No issues so far 12/22/2012
- Huge capacity
- First 4TB drive to market
- They run cooler than my previous Barracuda 1.5TB disks
- Rated for 24x7 use (though don't mistake these for "enterprise" class drives)
- Lots of other people are reporting problems (mainly high infant mortality rates).
For the last two months I've had 6 of these drives in a RAID array on an Areca ARC-1280ML (w/ 4GB BBU cache), under what I would call "medium duty" usage. Not a single problem so far, and great performance. I've been monitoring SMART stats with Hard Disk Sentinel and haven't yet seen any reallocated sectors. Temperatures stay around 35°C; and have never exceeded 42 (with push-pull cooling). The drives are just as quiet as any other modern HDD.
Taking other reviews into account, I suggest you take the time to break in new disks (exercise them with a period of intense reads/writes to weed out any premature failures) and then install them in mirrored, RAID6 or RAID-Z3 configuration. Array rebuild times for 4TB disks are huge; don't go RAID5 with consumer disks (Google "RAID 5 URE" for why).
Based on my own experience, if you heed the advice above, I see no reason to avoid this brand. All 4TB models are new and it will take time before any meaningful "in the field" reliability metrics are known. The seemingly-high DOA rate (especially on RMA replacements) is a cause for concern, but keep in mind users with negative experience are far more likely to leave feedback and those who are chugging along just fine.
