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?
