Windows 7: WD Black HDDs - Not RAID Compatiable????

Update to the WD Caviar Black non-RAID support issue

Hello 7 Forums, 1-year lurker new poster here, with an update to this issue.

As an update to this older discussion that is very relevant, I've been experiencing crashes with my 2 1TB WD Caviar Black drives in RAID 1 recently. Symptoms seem consistent with this lack of a TLER. Calling WD Support, they said that even though you can use these drives in RAID 0 or 1 arrays, they are not guaranteed to be flawless. I could barely believe that claim, since I remembered reading from the product descriptions for the drives before I built this system that they specifically had been tested for RAID 0 and 1 compatibility... so I went digging.

HerrKaLeun you would like to see this, based on your post above regarding clearly labelling these drives for this issue. This WD Caviar Black product page here: specifically claims in the "Applications" section at the bottom of the first page that (and I'll quote):
"Desktop / Consumer RAID Environments - WD Caviar Black Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 / RAID-1)." The publication date on that .pdf sheet is March 2011.

So, are WD incompetent, or lying? They claim up to two months ago that the Caviar Black drives support RAID 0 and 1, but then their tech support claim (one did so to me not 20 minutes ago) that "well, it does work in those, but it cannot be guaranteed to work all the time." In my book, as an engineer with graduate degrees, that means THEY DO NOT WORK.

Imagine if you were running only RAID 0, not RAID 1, and got this "normal" failure? Boom, data loss... and their response would be that "well, they're not recommended for RAID in data-critical applications," even though their own spec-sheet on the drive claims that they're tested for it in the drive's Applications section? Anyone else picking up a lot of cognitive dissonance here?

I've lost a lot of faith in WD today; I found their product support excellent in the past, but this "it works most of the time even though we claim it works perfectly and when it fails it could be catastrophic to your data system" BS is beyond the pale.

Any recommendations for Seagate or Hitachi drives that are known to be RAID 1 solid?
