I have a 5 disk Raid5 array of Western Digital Green (WD10EADS) 1TB. Raid5 is via Windows Server (software raid).
One disk has failed, and it looks as though I can't get the same model replacement. I've also read that the newer (consumer level) WD alternatives will misbehave in a Raid array (TLER issues etc).
The array has been powered up for 29,000 hours (3.2 years). Given that these are consumer drives, should I try to replace the dead disk or assume that the rest are going to die soon and replace the whole lot?
Edit: Just realised that rep doesn't transfer from stackoverflow, so I can't upvote just yet... sorry!
