I've just been replacing my desktop drives (all seagates, 1, 2 and 3 TB) as they fail. I've got 5 WD REDs now, in two separate arrays. I think 2 2TB REDs (out of 7 drives total) in my main NAS raid5 array (If I had room for one more drive, I'd make it a raid6), and 3 3TB REDS (out of 6 main drives, one hot spare, and one cold spare) in my backup raid6 array. Yeah, I've become paranoid enough that I have a full backup of the main NAS array now. I actually had to use it recently, due to a really stupid mistake I'd rather not talk about that wiped the filesystem ;D probably half of the array "failures" I've had were pebkac, so having a full backup copy is incredibly important for me. The backup array also stores backups of my /important/ rsnapshot backups of my machine configs, documents, and other important things. > I will look at the the raid timeout.
