The most important feature you look for a flash drive is the speed of data transfer and with this item you have got it. I had owned a flash drive previously and it was 256MB memory. This one has greater memory and is still fast than that!!!

The flash drive is fast in copying files and data. I had tried with big files, and it seems to be pretty fast and its unique design of gripping makes it easy to handle and install to a USB port.

It is a crying shame that this device did not live up to its most important advertized feature: its storage capacity. I chose the "512MB" TravelDrive due to its physical design - the cap is very secure, and it is the cap that can attach to a keyring, not the stick itself, so you don't have your keys hanging from your computer when you use it. It also sports a large rubber grip for ease of insertion/removal. Sadly, the reason "512MB" is in quotation marks is that it does not contain 512MB of storage. Even by the definition of an MB being only one million bytes, my TravelDrive comes up short at 498,122,752. It should have at least 512,000,000... and I've compared other devices from other manufacturers and they have always met "MB = million bytes" at the minimum. (A witness has a SanDisk 512MB Cruzer Mini himself, and his clocks in at over 515,000,000 bytes, for comparison.) The stick tested fine in every other way - it seemed reasonably fast - but I paid my money for the advertized capacity, and I didn't get it.

That is not a small difference. At best, mine is defective; at worst, this is grand scale [...]. Either way, that's one strong recommendation against buying one yourself. Incidentally, I contacted Memorex Tech Support, and their reply was a "return procedure" form letter; no thank you, I'll just return it to the store and get one from a different company. - ZM

I have two of these memorex jumps "thumbdrive." Both have worked fine and taken a lot of abuse as well! No problems with pc or mac, usb 1, 1.21 and 2.0. you don't need any drivers, just stick it in the usb and it comes up as a drive adn you can drag and drop.

I have had problems with cuprrupted files on cheaper brands but never on memorex. Memorex support is great, I had one drive I crushed in a door (my fault and a strong enough impact to also destroy may car alarm gizmo) and they sent me a new one! I have had other brands (ironically the lexar "sport"), where the keychain holder broke, memorex is actually more study than most)

Memorex jumps are also true usb 2.0 and there are a few cheap ones that aren't.
