I have a Linux software RAID 6 setup with a bunch of 2TB Western Digital Green drives. The setup works well for a home system on a budget, but resource demands are growing and false drive failures are becoming more frequent. (Which often leads to re-builds, which I imagine isn't good for the life of the drives.)

I've been aware all along of the TLER firmware issue and most of the drives I own were successfully patched with a firmware update to counter that issue. Not all, though. (Depends on the specific model number, Western Digital updated the line to no longer be patchable a while back.)

As the prices of drives have continued to drop over time, I'm considering starting to replace these with a more officially RAID-friendly equivalent. However, it's kind of hard to see past the marketing message and into actual technical information.

I'm not asking for a product recommendation. Rather, advice on how to effectively research the products and what I should specifically be looking for. For example, I'm currently looking at the Western Digital Red line. It claims that it's RAID-friendly, but how can I know if that includes Linux Software RAID? What are the hardware and/or firmware specs I should focus on?

Often the word "enterprise" was tossed around to indicate drives raid (segate intel). Actually drives good for servers, Datacenters. The WD black was used a lot for raid, and it worked fine, even though WD says "Desktop drives are not recommended for use in RAID environments" and recommend red "With a 35% MTBF improvement " and 2X costs. The OS does not matter so much as the "type" of raid, and raid hardware vs software and all. Those differances is what made green drive issues. (even though I find greens worked fine). And the Overall reliability of the drives. Focus on having backups :-) –  Psycogeek Jul 30 '13 at 4:38
