I just connected this drive to my Mac Pro, and it works as advertised. It is also calm, and drive access for substitute is pretty straightforward. But, I was surprised to discover that it uses Apple’s software RAID for mirroring, rather than implementing hardware RAID directly. Why should you care? Because Apple’s software RAID is not good, in my experience. In specific, when it discovers a read error on a drive, it considers that complete drive to be failed. Suppose drive 2 really fails. You pull it out and replace it with a new drive 2. Now software RAID replicates the contents of drive 1 onto drive 2. But, if it encounters a read error while reading drive 1, it’ll refuse to restore the RAID to full functionality, and you will have to restore from backup. This may sound not likely, however Western Digital’s datasheet for the drives in this unit quote a maximum unrecoverable read error rate of 1 per 10 14 bits. Think about that a 4TB drive holds 4 10 12 8 = 0. 32 10 14 bits, if you read the complete drive, there is up to a 32% chance of an unrecoverable read error occurring. Doh. This really bit me on the RAID I am using this drive to replace. The sad conclusion: using RAID 1 (mirroring) on this drive results in a lower improvement in dependability than you’d expect, and is no substitute for recurrent backups.

Update 9 Sep 2015Last update. I just wanted to let everyone know there’s a way to encrypt a RAID volume without purchasing an app. The information may be found herehttp://apple. Stackexchange. Com/questions/81504/why-doesnt-filevault-work-on-a-raid-volume————————————————-Update 27 Jan 2015I’m writing this update as a public service announcement that to get a drive with error correction or TLER is not as simple as I thought. I had a gut feeling I should read more about Western Digital Red drives before spending close to $200 on a couple, and I am happy I did. So what did I discover? Are Western Digital Red drives good for an enclosure that holds 2 drives? The simple answer is, if you’re running RAID 1, yes. If you’re running RAID 0, no. The long answer I found on a forum is:The reason you do not want TLER in RAID 0 is TLER is intended if a drive in a RAID array hits a bad sector, instead of keep trying to read the sector, the drive gives up after 7 seconds and tells the RAID controller to manage the error. The controller then finds a redundant copy of that sector data from another drive in the array (with RAID levels 1 or 10) or calculates the missing data from parity info (RAID levels 4, 5 and 6). The problem with TLER in RAID 0 is that there’s no redundant copy of the data anywhere, nor can it be calculated from parity because there’s no parity. You need the drive to keep trying to recover the data from a bad sector, because good or bad, it is the only copy you have. Hence, TLER in RAID 0 is bad. Now I understand why Western Digital gives us Green drives with this enclosure.

Bought this some years back after a few of failures with my 4TB Seagate drives. Was not a big fan of Western Digital for some years do to subpar merchandise but I have to say they have changed my mind with this drive. I bought the 8tb variant with the thunderbolt connection. Its been flawless since the start, calm as may be, and the software that comes with it for the MAC works perfectly and updates on a regular basis. Write speeds are great and it reads fast enough to not give me any delay when streaming music or movies off of it to my wireless devices or apple tv. Its a great purchase and I am happy to see the price coming down gradually, I will be buying another in a year or so.
