The SanDisk Cruzer Mini 1GB USB drive that I ordered from NewEgg arrived yesterday. It's about the size of a pack of Wrigley's gum and is thin enough that it shouldn't block access to the other USB port on my laptop.
The unit came with three, differently colored caps for the male USB connector, and a lanyard. This morning I copied over between 550 - 600 megs of files. This took about 5 minutes using the USB 2.0 port on my Dell Latitude. While backward compatible with USB 1.1, the read and write speeds will be much slower.
Incuded with the SanDisk unit is their CruzerLock app, which can be used to encrypt a portion of the drive.
I plan to leave some free space on the drive in case I need to use it for sneaker-netting files from one PC to another. If I run into any weird issues I'll post them as well.
