The Lacie’s Data Bank pairs unprecedented mobile convenience with exceptional technology ideal for transporting up to 40GB of data. All of Lacie HD Drives are shipped with comprehensive disk management software for Macs and/or PC's, as well as applicable USB, FireWire or SCSI cables, power cables and manuals. As for the CMS the Mac compatibility is currently under development. That is why you only see the Lacie advertise the in the stores.
The Lexar Elite is secure to use anywhere. There is the Lexar's Traveler Elite, this particular drive could carry your Internet settings, email, and address book on it for use on any computer, and it said you could browse the internet privately without leaving a trace on the computer that you use. All you have to do is open up the drive in My Computer and click on "Traveler.exe".
Another thing that I like about this is that if your motherboard supports booting from a USB device, you can boot from it.
