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 !
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.
Summary: Speeds I achieved with this drive were about twice as fast via Firewire 800 as they were via USB2. That's all due to the interface and should be expected. Unless you're forced to use USB2 with this thing, use the FW800 instead.
Pros: Nice small drive Powered from the data cable Great speeds via Firewire 800 It's from Western Digital! USB2 and 2 Firewire 800 Ports (so you can daisy chain it with other stuff) Completely quiet. Comes with both cables (USB and Fw800)
Cons: There really are no cons for the drive itself... But Windows 7 won't natively talk to this without either loading software for it or reformatting the drive. I sorta think that's unfortunate, since a Mac will read a Windows (NTFS or Fat32 drive) without any special software. You'd think Windows 7 ...
