I use this type of memory card for my Fujifilm A340 4 megapixel camera and i have never had a problem with it.
There has never been loss of data / corrupt files which is one of the most important things you want from a digital camera memory card.
On the 4 megapixel 'fine' setting it can store about 60-70 photos which is fine if you have access to your computer to download them and start afresh, but nowadays plenty of people are looking for more storage space so less time is spent downloading.
But if you just want to print standard size good quality photos then this tends to hold around 160 - 180 pictures.
This ment when i was on holiday i only had to go into a shop twice to put them on a cd and wipe the card
- although some might say 430 photos is a bit extravagent...!!
On the web style setting this card can hold over 1000 photos which is great if you are wanting to post lots of holiday snaps on the internet say.
The actual card itself is very small (20 x 25 x 1.7mm) so if you have more than one they aren't going to take up your handbag space.
The best bit about this card is the fast read and write speeds:
Read speed 5 Mb/s
Write speed 3 Mb/s
This greatly increases the battery life of the camera you are using the card in as less time is spent saving/deleting a picture to the memory.
It operates at 3.3V and this card can be picked up from £10.99 which is a bargain for such a stable card.
If you have a camera which takes xD picture cards then BUY IT .
If not then i would seriously consider getting a camera which uses these (if you dont already have one) as they seem to be pretty future proof.
Hope that helps anyone who would consider purchasing one.
