Summary: I did quite a bit of research here on Amazon and other places before deciding on this particular model as my primary backup to my desktop iMac. I can honestly say, this little unit is amazing.
Summary: I've ordered a number of external hard drives on Amazon; so far, the WD My Passport Studio 500 GB is the keeper. It's portable, holds the same amount of data as my PowerBook's hard drive, and couldn't be easier to deal with--it works quite literally out of the box.
Summary: Writing this review after more than two years of owning this drive. Have had absolutely no problems with it. I have a couple of Mac partitions and a windows partition on this and its been read and written to countless times. Solid drive, but a really late review !
WD My Passport Studio 1TB Mac Portable External Hard Drive Storage...

Summary: I ordered this to augment/replace an older WD drive that was only 250MB, specifically because my Time Machine backups had eaten up all but 3.5MG of the available space. I'm using the firewire connection and all appears to be just fine.
Summary: I bought that drive a few months ago when my storage needs got over control. I needed something small to hook-up to my laptop who act as a desktop replacement. I did not want a desktop drive, too much hasle, noise and wires. I recommand that drive to any MBP owner.
