Thanks for the tips and link. I don't need a portable but the western digital units looks like they would be ideal for work. This requirement is for my home office for backing up/freeing up space so high speed is not essential. I'm going to read some more reviews, hadn't even thought of doing that thanks Charles.
i recently went through a similar dilemma as I had run out of room on my external Lacie drive. I have always been a great fan of Lacie products, I have the screen etc and I have always recommended their products over the years.
I began my search for a reasonably priced 1TB external hd that would also give me a good transfer speed. From endless searching and reviews I come to the conclusion that the Western Digital My Book Studio Edition was the best solution. The thing that made my decision was the various different connections, including the common high-speed links eSATA and Firewire 800
I currently have an internal Seagate drive in my G5 and I have unfortunately got a dodgy one, which could drop out any day. This has obviously lowered my opinion of Seagate, hense the move to Western Digital.
I'm currently running a Seagate FreeAgent Pro, and touch wood not had any problems with it, also came with a 5 year warranty, although that's not much help if it ever does have a serious error and you lose the data!
If you get a 2TB drive but with 2 x 1TB SATA drives, you can then format it to RAID 1 which basically gives you 1TB of storage but automatically mirrors everything onto the other 1TB. As they're separate drives if one should fail you have an identical copy on the other.
It obviously makes it an expensive 1TB drive, but with added security. And if it's full of commercial projects etc. then it's certainly worth it.
We used western digital throughout the company and had 5 1TB mybooks of which 4 crashed and burned, unable to retrieve any information, they lasted just over 2 years. We may of been extremely unlucky but I personally wouldn't touch a western digital again.
