Have narrowed it down to two. G Tech G Drive Mini or Seagate Free agent Go , both have great reviews and are Mac and Time Machine ready. The G tech is a little pricier, but cost is not a factor.
Greetings, i purchased Seagate Momentus 7200.4 ST9500420AS - harddrive - 500 GB - SATA-300 and it works flawless. I haven't bothered to update the EFI to 1.7 though so i can't say anything about that. My impression is that the harddrive is very silient and very fast, go for it!
I use G-Tech drives for my critical work. Very robust drives (especially the mini's which are outrageously cute). I beleive the mini ones come with a carry case but i'm not sure.
They come with a three year warranty. Keep that in mind when making your comparisons. They were bought out by hitatchi some time ago, so they use exclusively hitatchi drives.
Two very ugly drives. What's wrong with the WD Passport? Screw firewire.
That's a nice drive!http://eshop.macsales.com/shop/firewire/on-the-go
Two, Western Digital external drives are NOT bootable on Macs. If booting from the external matters to you don't get a Western Digital.
