issue with the model drives that I'm using. I've got WD 3TB Green EZRX drives, which I recently found out via the RAID Wiki, that they didn't have error correction (after I spent over a thousand dollars on the drives in 3 years) ... Had I known better, I would have opted for different models.
That's not entirely true. EZRX drives have just as much "error correction" as any other drive. What they don't have is the ability to rapidly terminate their error correction (WD call it Time Limited Error Recovery or TLER). Nothing wrong with that provided your OS storage stack timeouts are set appropriately, as without that the drives will take longer to process the error than the OS will wait and things get ugly resulting in drives kicked from arrays.
Sure, they're not the best drives for the job, and buying new I wouldn't recommend them; but disable periodic head parking and spindown, set the timeouts appropriately and they'll do the job until they need replacing.
