I have many many flash drives, with this one being one of them that I have used for quite some time now and find it to be as good as any of the others.
It is compatible with your typical USB 2.0 and the even older 1.1, although there no nice surprises trying to get a higher transfer rate with a USB 3.0, so if your PC has a USB 3.0 port you're not going to get the higher speeds using this in it.
Don't get me wrong, the speeds are good enough. I sent a 500MB file over to it in less than a couple of minutes, so there's no real waiting about. But if it's speed you want then 3.0 is the way to go.
It is what is a FAT file, which doesn't mean that it has eaten all the pies, it just means that the file system is FAT,
It also boast to be something called RoHS compliant, according to the info on the box. This simply means that it is EU safe as it has passed the Restrictions of Hazardous substances... (and no, i'm not that clever, I checking up on line to find out what RoHS was all about, although I do Know what CoSHH stands for..???).
It's your standard capped flash drive, which means that there's a chance you could lose the cap if you're not too careful, and it is small enough for your pockets, being about 70mm long, 20mm wide and 8mm thick. There is a little hole on the rear end which is designed for a keyring to slip through so that you can put this with you bunch of keys.
And the price for this flash drive is a very nice £8 or so … although the price varies depending on the GB size versions you buy. The higher the GB the higher the price.
