Yes, I use Samsungs F1's and like you it was a budget driven choice. I have 16 of them however.
One thing to consider is that you intend to use them in Raid0, which has no redundancy. Reliability is therefore a critical consideration. Bill got a nice deal with the 7200.12 disks. That is one possibility, the other is the WD RE, which you mentioned, or the Samsung F3's. However, notice that I had 2 out of my 16 drives fail within the first 4 months. Both replaced under guarantee and after rebuilding the array, no data loss. That, unfortunately is a luxury you don't have with raid0. It is a difficult call to say "get this one". How critical are the data on the raid0, how easy are they to restore in case of a disk failure, what is that worth to you in $$$. My gut feeling is that the WD RE are the most reliable, the Samsung's have the best price and the Seagates 12 series are somewhere in between.
My gut feeling is that the WD RE are the most reliable.
I agree. I think I just need to bite the bullet and spend the money. Because I'm doing RAID0 and then backing up right after each editing session, I'm better off paying for reliability (and hope one of the drives doesn't go kaboom in the midst of editing). Eventually I'll get to a rack with 1+0 for speed and redundancy.I suppose I could do RAID1 for now, but I'd rather have performance. Plus, the stuff I'm working on isn't THAT mission critical!
Thanks for the input.
