My guess is, very little, and no. It's not like they are going to tell you "it's going to die any day now", even if they know it is likely to. :) Any drive is a crapshoot, IMO. You might get lucky, but it WILL die and you're better off planning for that. My server was recently upgraded, and I'm now running RAID6 (raidz2) with 2 arrays for a total of 4 parity drives. Kinda sucks to lose that much space to protection, but with 1.5TB drives it takes so long to restripe in case of failure that I want the extra protection. <br>
<br>The bigger question I would have for WD is, when are you going to stop causing problems for people wanting to use your drives in a RAID config? Even the latest drives seem to cause people problems with the TLER settings. It's caused me to write off WD completely as I don't run non-RAID in anything but a laptop these days. It's one thing if they set them up from the factory that way if it makes things better for single-drive users, but it should be configurable if it causes problems for other users. And no, "buy the enterprise drives" is not an acceptable answer. They are overpriced and unnecessary for home and SOHO setups. <br>
