SanDisk 4GB Cruzer Titanium Flash Drive
The SanDisk 4 GB Cruzer Titanium is quite a bargain. If you're a PC person running Vista, this memory stick can augment the RAM that's available to your computer. In this case adding 4 gigs of RAM would be a huge improvement for most PC's. The Cruzer Titanium is also very tough - it's got a metal case and a convertible nub that pulls inside the metal case for protection.
I've been using the 2GB version for a couple years now, and the thing is tough as nails. The best part is that there is no connector cap to lose; the business end of the flash drive just retracts into the memory stick like a switchblade. The flick-out connector system has gotten a little looser over time, but it still works like a charm. Flash memory is the wave of the future.
This flash drive is cool because of the retractable USB connector which means that there's no cap to lose. It offers password protection and also backs up your files online so you don't accidentally erase them. At 4GB, this is one of the larger USB flash drives.
