what is your experience with 3TB drives, WD and others?
I have some experience with the 2TB Green drives, the ones I bought right after launch had a very high failure rate, the ones I got as replacement and purchased 6-12 months after launch, have fared a lot better.
I am however replacing them now with WD Red drives (only one so far, had my first failure in a year a few months back). The raid resync went very smoothly, I had constant 130 megabyte/s write speed to that 2TB Red drive during the resync.
As for people still talking RAID5 for these sized drives, I don't understand anyone not running RAID6. The rated read error rate on the drives are frightening (10^-14), so with single drive failure and doing resync, it's not uncommon to get read errors. RAID6 is definitely recommended.
