Sandeep, I've been running WD Blacks in a RAID 10 on my server for almost 3 years, what's wrong with them? Other than I have had one fail per year (which I just RMA and replace) they seem to be fine.
The WD Black drives don't have TLER. TLER basically tells the RAID controller that the drive has an error in <7 seconds usually and then that error is corrected. Now the WD Blacks which don't have TLER can take up to two minutes to respond after finding an error. This long response time makes the controller think the drive has failed even though it's a recoverable error. It's probably why you see one fail per year. Drives don't (normally) fail that often. It's also dangerous since you could lose the whole array.
What do you recommend I move up to?
The Western Digital RE4 line is better. They are SATA drives with the enterprise features like TLER. They have SAS versions as well.
