I have entrusted this SD card with family photo's, documents for work, music, precious content which i need to keep safe. I wanted to transfer the content between my work computer and home macbook so i needed one of these to do the job. All i can say is, it's done the job well.
First impressions were a bit unsettling, with the packaging being almost impregnable and i got a bit worried about it working correctly for the first ten minutes until i realised the tiny lock button on the side. From that point onwards though things have been very smooth, i normally get a write speed of around 5MBps according to OSX Mountain Lion and a read speed of between 5 and 7 MBps depending on file size and whether or not my Macbook is having a bad day or not.
The card is very durable, it doesn't snap easily and can be rammed hard into SD slots all day long without breaking or bits chipping off it. Good news for the sticker too; that hasn't come off or jammed any of the SD slots it's been in so no problems to report there either. Given that these are quite expensive you would expect this sort of quality from them, and i'm glad it lives up to those expectations.
The memory card is easy to setup one you get the packet open, just check for the lock button at the side and ensure this is rammed all the way to the top. if it is slightly away from the top by about 3mm it can sometimes still stay locked. There is no quartz style lock on this so you have to check with your fingers if it is in the correct position.
Files have never corrupted on this device and reliability is good. I haven't lost data or found any files that moved themselves, and accessing encrypted files is just as easy as the unencrypted ones.
I have on many occasions left the SD card in the slot overnight, and even for 24 hours straight. It still works, and by the time i take it out, it's still reading at the same speed and there are no issues where file transfer is concerned.
Overall a fantastic little device with i have entrusted to keep precious content on. It is reliable and well built, a highly recommended SD card.
So if you have received or purchased a new digital camera over the holidays, you will have been greeted by the unpleasant message that informs you that you have no memory. If your camera is an Olympus, then you will be completely unaware of the need for a memory card until getting home and opening the box. Trust me, that is really annoying.
Sandisk seem to have become the dominant player in the memory card market. When looking to purchase a new card, the inclination will be to go for one with a larger memory, something like a 16gb or 32gb. The price will no doubt be more economical and just makes more sense if you only have one to worry about. Wrong. Memory cards can and will fail, so if you have 1 big card with all your prized pictures on and it dies, you won't be best pleased. Again, trust me.
So a 4GB is big enough to last you for an event, say a holiday and you can pick them up in packs. Little bit more expensive but that is piece of mind for you. So what do you get, not a lot as it happens. A roughly one inch rectangle made of blue plastic and approx 2mm thick. If you are of a mind to do so, you could snap it but other wise it can be thrown into a pocket or compartment without too much concern. On its reverse at the top are the contact strips. These are how the data is transferred from source to storage and eventually to your PC, so avoid damaging these. It weighs very little, if it is in your pocket you will forget about it.
In terms of storage, it will hold 1500 good quality photos and about 4 hours of normal video footage. Of course that can be increased or decreased by altering the quality of your shooting. Amazon.co.uk is selling these for just under £4.
If I was to have any complaints, then the lack of a protective case would be the one issue. I've just had to spend £2 for ten of them. When you consider the amount of plastic packaging the cards come in, it seems a little silly to not have something to protect your investment. In terms of card failures, I have suffered none and reviewers accross the web indicate this is a very safe product. So I think there are more people than just me that you can trust on that count!!
I have a number of different memory cards for my cameras as I have three different cameras which I use for different purposes. I have to admit that generally when I buy a memory card then I only tend to look at the size of the card, the type of card - and the price - and so far using that strategy really has served me pretty well. I do have a Sandisk (SD) 4 Gigabite card (as well as an Sansdisk 8GB) for my point and shoot camera and I've had it for the last two years without any problems at all really. The card was bought from Amazon.co.uk for just £6.70 - which really is a pretty amazing price!! I largely bought this disk because of the price which was about a good a price as I've seen. I have found that you generally get the best deal online, but you can pick this up from many high street outlets, such as Jessops, Dixons, Curry's, WHSmith etc.
This disk is suitable for any device that is SDHC compatible - which is a large number of point and shoot cameras. There are other manufacturers of SDHC cards, but I have to say that I have always found Sandisk to be really reliable in as much as the file content is kept safe and secure. I have used a few cheaper manufacturers and, on occasion, I have found that the file content had been corrupted. For that reason, I do like to use Sandisk because, so far, I have found Sandisk to be 100% reliable.
I have found that I can get around 250 photos that are around a 12MB size on a 4GB disk. The files can be compressed so that you can get more photos onto the disk, but this does diminish the quality of the photo and so I would recommend that you do not compress the files unless you absolutely have to. As the disk is so inexpensive and accessible, I would recommend simply buying more disks!
Transferring the files from the disk onto my Epson P7000 is always unproblematic and pretty quick. In addition to this, if you want to protect the files you have on the disk you can flip the little white lever and then you can't accidentally delete the files that you have on the disk.
Overall, I would recommend the Sandisk 4 GB and can't think of anything to not recommend it.
As a photography mad college student that tends to spend more time taking photographs than on things that I really should be doing such as coursework, I've found that I've needed quite a few memory cards over the years to store the photos I take on. This was just one of the many that I've acquired over the time I've had digital cameras for and I recently found it up so I thought I'd do a review on this one in particular.
I bought it about a year ago from a digital camera shop inside Asda in the Birchwood Centre in Ashton Under Lyne in Manchester for £9.97. I bought it because my old one was full and it was a nice day for taking photographs. It wasn't necessarily that I had to buy it, it was more of an impulse buy than anything else. I know that the same one is now available in Tesco for £7.74 though and I'm fairly sure you could get them for even less than that if you bought them online on eBay or Amazon. These memory cards are the ones most commonly used in digital cameras so they should be fairly easy to get hold of, I would think.
The colours that were available when I bought my one were just blue and black but this may have changed since I bought mine. I bought a blue one because my old one was black and I wanted to distinguish between them easily without having to read the card if I needed to quickly get the memory card into the camera for a photograph.
The shape and size of this piece is pretty much the same size as a stamp which makes it pretty easy to lose but then I suppose if you have somewhere to keep it, as I now have having bought a memory card holder from eBay for 1p (it really was a bargain - I half expected it not to ever turn up but I thought for 1p I'd try it and it actually arrived!) I now don't have to worry so much about the possibility of losing it as often as I used to. If you get one of these memory cards, I would definitely recommend that you get a holder as well because they're definitely very useful if you're always losing small things!
Another bonus point is that there is a 'lock' feature on it where you can choose to prevent the memory card from being wiped. One of my old ones didn't have this feature and you'd be surprised how many times I caught it and ended up losing the photos I'd taken. I think this is a really good feature on this one because it prevents data loss.
As for the amount this memory card can hold, when mine is empty it can hold the following amounts of photographs:
2M HD - 12873 photographs
3M - 7723 photographs
5M - 5941 photographs
7M HD - 4543 photographs
8M - 3861 photographs
10M - 3217 photographs
12M - 2757 photographs
14M - 2573 photographs
As you can see, this holds a lot of photographs so I think this is a very good memory card and a good amount of GB to have on a memory card as well because it can hold a lot of photographs so if you're away for a while and can't get access to a computer to get the images off it doesn't matter too much. On average, I will probably take around 100 images a day so this would last me for 40 days on average of taking photographs without emptying the memory card. I think that this is a very reasonable amount of space. A larger one would probably be more useful to me in a way but then it's all a matter of how often you use it.
When it comes to taking the images off of the memory card, I find that the easiest way of doing this is to copy the images into a folder already on the computer and then delete the images from the memory card. My computer is a windows 7 computer and it has no problems with loading on this computer. My old vista computer had no problems with it either which I think is a good thing because both of these are known to have problems with loading storage devices.
Overall, I have to say that this is a very good memory card because it has a decent amount of space on it and is easy to transfer data to and from. I also think that the price is good, averaging at £2 per GB which is very good in my opinion given how long you can use them for and how the space never really gets completely filled up because you can just delete something.
Surely, a memory card is a memory card, right? I mean, I understand there are different sizes, which makes sense, but surely there can't be much that one brand would have that much difference to the next, would there? At least, this is the attitude I used to take, until I started working with all manner of USB sticks and contraptions that need varying types of memory card.
The most common shape of memory card is this one, the one you see here in the picture. It's rectangular with a slight bit of the top corner missing, as if someone has snipped it off with a pair of scissors. SanDisk have been a leader of memory cards for a while, and are generally associated with good quality. I have always used them personally, and find them somewhat more reliable than some other, cheaper brands, whether it be transfer speed, security or general ease of use. Usually, you're likely to encounter 4GB cards, meaning they could hold 4GB in terms of memory, whatever type of file it may be.
The 4 GB SDHC card is a little bit different though. The first time I used it, I wasn't really sure what the difference was, and was surprised to find that the memory didn't actually get used up as much as I thought it would. It turns out that the SDHC (which stands for Secure Digital High Capacity) can actually compress your files to make them seem like they take up less storage space, thus effectively giving you 32GB of memory in some cases. This isn't necessarily everything you store on it, and I'm still not really sure on exactly what level it works best, but with high quality video, for example, you really can notice the difference and get more onto the card.
One problem I have found, though, is compatibility with various devices. SDHC is still a relatively new concept, only a couple of years in the making, and will not work in devices that don't support the format. Newer devices will support a basic SD card, but you may need to double check SDHC compatibility before buying something too powerful for your device to work. I had this issue with a card that my video camera wouldn't support (it was an old MV750i that could barely support a 2GB card anyway) and so found out the hard way just as I was going on holiday!
Transferral of data was easy enough. I found it runs quite quickly once transferring starts. A good example is always transferring it to your computer. I have a new laptop, and it picks the card up straight away, and pulling data from it to go on the laptop is very quick. Speeds can vary, but even on slower days it's quick enough for my needs. There's also a handy tiny switch on the side that allows you to lock it, meaning that it can be read but nothing can be saved on it. I can't see why I'd necessarily need this on a day to day basis, but if I wanted to make sure nothing happened to my photos while my 6 year old son was looking at them every now and then, this is one way I'd use them. Other than that, I'd keep this unlocked, but it's nice to know the option is there.
Other users seem to have had issues with this type of card freezing on them. I can't say this has happened to me, and I've been more than happy with the reliability of the SDHC from Sandisk. They continue to maintain their reliable status with me, and I can't see a reason I'd opt for another brand. I'm aware that speed and reliability factor in such decisions, and am keen to make sure I keep abreast of developments with cards, but for the moment, I don't feel I need to look elsewhere. I'd happily recommend this card without hesitation. Pricewise, expect to pay under £10 for it, and I know that some places are creeping the prices down to under £7 as memory continues to improve and become cheaper. A price well worth paying. Recommended.
With memory cards you always want one which is going to have high memory and good ability to keep information safe.
Sandisk have always been the top company for me in regards to memory cards and this has not changed for quite some time. There Sandisk 4 GB Class 2 SDHC is used primary for my digital camera.
What I got with this memory card was the SDHC part which stands for Secure Digital High Capacity the member of staff behind the till told me it would increase the memory to 32GB.
I had never heard of this before normally you get a 4GB memory card you get just the 4GB memory.
The design is blue and it is hard plastic and it is very much a rectangle shape and has the logo of the company on the front of the card. You have a section at the top which is where the information is transferred to the memory card.
I have used this to transfer my photos from my camera to the computer and sometimes vice versa because I love to transfer my images to a camera to show off to people who I know. I have never found an issue when it comes to transfering files to the memory card but I have in other ways.
Once I put over 200 pictures and they were ranging between 2mb and 5mb and it was for work purposes. Apparently the memory card claimed all files were corrupted and it was a shame. I then went back to my camera and the files were there so it was like some computers failed to find the files on the memory card.
One of the other problems I had encountered as when I plugged this into the computer it sometimes took ages to load up the files or it would freeze completely and had to result in me restarting the computer which was slightly frustrating. I do not think this is a good thing to have with a memory card at all.
You have files such as microsoft word documents which you can use and they take up hardly any memory at all. I have to admit with the SDHC part I unsure what this actually does. I have never filled the entire memory card up before and mainly around 2GB with various files and I would say how many it can take but each camera photo is different.
Some 3MP camera images I took were 600kb and some of the 10MP camera images were 4.1MB so the massive difference shows how hard it determine how many photos can be fitted onto this memory card.
In my view for £8 for which I paid for this it was good for great memory and it was decent also because it offered me a way to transfer files but having corrupted files when they were not is a problem for me. As mentioned above the SDHC part I am sure about and not really sure what it offers overall.
As a busy graphics student and keen photographer, I have a fair few SD cards scattered about my room. I previously reviewed my 2GB SD card, but since then I have ventured into the realms of the 4GB SD card, as I felt it was time I got myself a higher memory card, as my 2GB cards filled up easily, with the amount of photography work I do for my course and with general camera use.
I purchased the SanDisk 4GB Class 2 SDHC (which stands for Secure digital high capacity) from Curry's, after being advised this would be suitable for my work. I paid something like £24 which I have since found is an absolute rip-off, as they can be purchased for as little as £6.65 on Amazon - D'oh! The design is pretty much the same as the smaller cards from the SanDisk range, blue and red with white text.
In terms of memory capacity, it does depend on what camera or other device you use to determine how many pictures/footage this card will hold. On my particular camera (Canon Ixus 900ti), I found it will hold 941 photo's/40 mins of footage. This could be increased or decreased depending on if I made the resolution of these images smaller or if I changed to a lower quality film setting.
I have found this memory card pretty invaluable, especially on my travels whereby I didn't have my computer to empty the card on to free up more space, as this held pretty much all the footage and pictures I needed to take. Although, the average piece of 5 minute footage ends up taking up about 400mb of room which can be a little frustrating.
A problem I have found with this card, is although it's fine with my laptops, my pc really doesn't like it and it tends to make it crash and essentially go in a huff. My pc is 4 years old and perhaps this is the problem, but either way it doesn't seem to want to accept anything over 2GB meaning I can't edit any footage on my PC without first transferring it to my laptop, and then over to my PC, which is a little time consuming and not to mention a hassle.
Having said that, I am glad I switched to a higher capacity SD card as it means I can get alot more work done and not have to worry I won't have any room left on my camera. I have also found this card to be extremely reliable, as I never get misplaced data or images and everything is as it should be.
When purchasing this, the salesman told me that different SD cards will perform at different speeds, and that the one I had bought wasn't "that fast at recording footage". I don't know if this was a con to try and make me part with more money or if he was actually telling me the truth, but I have found this SD card extremely quick at capturing footage, and gives great detail and speed when filming in HD mode.
Overall I am really happy with this purchase and would recommend it, but I would also shop around first as I paid about 3 times too much for this. As SD cards are quite delicate, I would also suggest having a little hunt for the SD Card protective cases I have seen, as you certainly don't want to damage or scratch these in any way! San Disk is a brand I trust when it comes down to SD cards, and so I would recommend them.
SD, short for Secure Digital, is a memory card format developed for use in portable devides, such as digital cameras and camcorders, PDAs, media players, mobile phones etc. While standard SD cards have a maximum capacity of 4GB, the SDHC variation, Secure Digital High Capacity, allows for more than 32GB. The SD format is one of the most popular ones for handheld devices, excluding devices from Sony, which typically utilise the Memory Stick Pro Duo format. Smaller devices often use the MicroSD or MiniSD variation of the SD cards, which uses the same technology, but in a much smaller physical size. The CompactFlash format is also present in the market, with competitive transfer speeds and price/capacity ratio, but is far less common.
This review is of the 4GB capacity version of Sandisk's SDHC memory card, which has been available since 2007. I got mine in 2008 and have been using it steadily since then as the only storage for my digital camera.
The card is made of hard plastic. It feels solid to the touch, and is thicker than my Memory Stick Pro Duo memory card. I really can not imagine physically breaking this card by accident. It comes in blue and has a blue and red sticker with white writing on it. The sticker does neither fade nor come loose after prolonged use. There is a slide on the side of the card that can be used to lock the card so that it can not be written to. This functionality is not likely to be needed by most consumers. It will write protect the card so that new data can not be written to it, and so that old date can not be deleted.
THE CARD IN USE
I've been using the card primarily as storage for my digital camera. Although the camera can be connected directly to the PC, I prefer to eject the SDHC card from the camera and insert it into the card reader on my PC. I do this to save battery power on the digital camera. The card is invariably recognized by the PC within a second of insertion. Pictures, video files and anything else you have stored on the card may then be viewed directly from the card or copied to your hard drive. Transfer speeds are very decent, at about 4.5MB write per second or 8.5MB read per second.
I did once experience an issue where the data on the card was corrupted. However, this has nothing to do with this being a Sandisk card, it's only related to my negligence. I am not sure exactly what I did. I think I must have ejected the card while the card was being read from or written to. What happened was that when I reinserted the card, I got a message from Windows that there was a fault with the device, asking me if I would like to scan and fix the problem. I clicked "yes", and this resulted in all my data disappearing. the space taken up by the files was not accessible to me, yet I could not see the files. What I then did, was run file recovery software on the card, and I was able to retrieve all the data. As mentioned, this has nothing to do with the brand of card, only a mistake I made that would have corrupted any card. A good tip to any user would be to "safely remove" the card within Windows after use, the way you would "safely remove" any usb device. You would then be prmopted with a message saying the card could not be removed because it still was in use if it was being read from or written to. Should you not be acquainted with the "safely remove" functionality of Windows, this appears in the taskbar, to the bottom right in Windows, and has an icon that looks like a gray usb plug with a green circle on top of it with a white tick inside of the green circle. Upon cliking this you can choose to "safely remove" the SDHC card after use.
One thing to watch out for is that there is SD and there is SDHC. First there was SD, which was limited to a maximum capacity of 4GB, and then SDHC was developed, which allows for higher capacities than 4GB. However, while SD and SDHC cards are based on similar technology and visually look the same, some devices that support SD do not support SDHC. However, SDHC devices are backwards compatible with SD. What you have to do if you are unsure if the device you want to buy a memory card for can support SDHC, is refer to the manual for the device, or the manufacturer's web site. I wanted to buy an SDHC card for my girlfriend's camera, however, on the manufacturer's web site there was a list of supported memory cards, and it did not say that SDHC was supported. Only SD cards were supported. Most newer devices should support SDHC, but it's always good to refer to the documentation for the device to make sure.
When I got the Sandisk 4GB SDHC card in 2008, I paid around £10 for it. Today you can get it for around £8, or alternatively get the 8GB version for around £10 or the 16GB version for around £18 (June 2010). I would wholeheartedly recommend the Sandisk card. The build quality is great, capacity is very good, I can't complain about the transfer speeds. If I was going to buy an SDHC card today, I would probably get the 8GB version. 4GB is more than enough for me. I've never ran out of space during a vacation. I went to Iceland for a week, and all the pictures and video I took came up to less than 2GB. However, 8GB would mean you wouldn't have to transfer your pictures to the PC as often to free up space.
I was able to find a 2 pack of this product for around £12-14 from HMV last Christmas. So for £6-7 each they definitely seemed a good deal!
And, still fine a year later they have proved worthy! I have used them in my digital camera, photo frame and numerous laptops and have never had a problem.
I only really use them to store photos and the occasional document and for this they tend to be relatively fast. I have never lost any data or had any corrupt files and they are generally just stored in a device.
There are more expensive memory cards on the market, however if your use is exclusively for photos/documents then this should be perfectly suited to your needs; for videos I would personally go for a faster card with greater storage.
Overall, I would definitely recommend this product and will in fact be buying more myself.
I use this card in my Casio Exilim camera and have tried it on two laptops. Of course the camera and laptop ahrdware will have a lot to do with it as well so this review and any other review you read will be biased. These are just MY experiences with the card.
For storing photographs:
Very reliable as expected from any SD card. It hasn't lost any data to date after two years of use and is ample storage for the amount of photos I take. At 7.1 mega pixels it holds over 700 photos and some short video clips. Read speeds are instantaneous on my camera, write speed is noticeable but ok for the casual user
For storing videos:
Likewise for photos I have found this SD card to be very reliable, I'm not sure how much video footage it can hold as I don't tend to take many video recordings. Again read speeds are instantaneous but write speed is noticeable (by write speed I mean there is a short loading screen once you have finished recording).
Data files from computer:
Once again no problems and read/ write speeds for small files and music Is quick. You would have to be fairly impatient to got frustrated by it. However read my next point.
This may be due to some sort of formatting done by my camera (I have never used any other card in it), but I can't get this SD card to work directly with any of my computers that have built in card readers (3 of them) it only seems to work if I use one of those usb sticks that I put the SD card in which cost a few pence on ebay.
