SanDisk Cruzer 4 GB USB 2.0 Flash Drive SDCZ36-004G-A14F

To summarize the reviews of 99% of the other reviewers and my own experience all at once, here is everything the potential buyer needs to know:

* If all you want is the best possible price on a USB flash drive, this is perfect for you. It performs and you can't beat the price per unit of storage (note, however, that WalMart currently carries them for cheaper).

* As others note, there is no way to connect it to a keychain, even though there is a metal post where a metal ring SHOULD be. If you're really desperate and broke, I suppose you could fashion something from a paper clip, but it likely would not be secure.

* Yes, the drive is very flimsy feeling, and I'm not 100% sure I'd even want it banging around next to my keys anyway. I'd also be very wary of it getting wet, because I've actually taken mine apart (trying to get a damn key ring on there without any success) and there's absolutely NOTHING between the tiny circuit board and the elements...Read more

This is a great, compact flash drive. I would recommend getting as big of a flash drive as you can reasonably afford- you'll be surprised how useful it is if you are moving between computers. Its far better than dealing a couple of CD/DVD-Rs or file transfers.

Its the fastest/easiest way to boot into Linux for my needs (student, learning Linux of course). I even had 1GB space left over that's on its own partition that's still FAT32 (the only format recognized by Xbox360). It works marvelously- and then I disconnect the drive and my computer (or any computer) boots into its normal OS.

My one complaint is the physical design of the keyring/lanyard slot/loop. The drive does not include a lanyard or mini-key ring, and the part is SO small that you can't simply attach a normal key ring. Pretty minor, but its...Read more

I have bought countless USB thumb drives over the years, and the brands I prefer are SanDisk and Transcend. After losing many caps, now days I only buy ones with RETRACTABLE USB connector, like this one. This SanDisk 4 Gb Flash Drive is very compact and has a higher quality feel compared to older models. It would be nice if the maker includes a lanyard, so that this tiny thing doesn't get lost too easily, but unfortunately these days it appears that no one maker does this.
