Good performance, potential issues with reliability
26 September 2013
Pros: It had a good performance and matched my expectation when worked.
Cons: My working environment requires large but relatively short-lived backups. Average size of backup is 74GB and backups are performed four times a day. I used the storage in RAID1 configuration. After four months of usage I noticed that some backups fail because storage unexpectedly run out of room. I run all tests provided by WD utility; and the drive pass all without any warning. Being familiar with WD service (I have few other WD devices), I even did not try to open a...
Bleeding Edge, Fastest HDD external to date. Raid 1, Raid 0, 2TB X 2 HDD

13 January 2013
Summary: I would have really liked to see what the USB 3.0 speeds were. I bet there are the exact same as the Thunderbolt speeds, but if that got out, they couldn't charge the huge premium of thunderbolt. Since both still need external power, I’m not seeing the advantage of Thunderbolt here. If it were an SSD, then the 400MB/sec speeds that thunderbolt can real world output could be pretty cool.
Pros: -The RAID option is awesome. 2TB redundant (Raid 1) or 4TB Speedy (Raid 0) or just 2 disks, etc.
Cons: No USB or Mac’s beloved Firewire? You drop how-ever-much this costs and they can’t add USB or Firewire port? Unacceptable. Also it’s quite bulky, but that’s understandable. Also, no on/off switch. 2/3rds of the price of this external HDD is this fancy enclosure, it should have ALL the bells, whistles and connectivity. At time of this writing you are paying $200 more for this Thunderbird over USB/1394, why not include their connectivity?
Summary: I understand this drive is marketed toward Mac users, thus the drive offers no other connection types like USB or Firewire. Also the drive does not include a Thunderbolt cable. That’s an additional $50 investment in itself.
Pros: It’s pretty good in size. Much bigger and heavier than I expected.
Cons: The Western Digital “My Book Thunderbolt Duo” 4TB is a little slower than other Thunderbolt storage devices on the market. Assumably why it is a lot more affordable compared to other available Thunderbolt devices out there.
Pros: Silent round, it doesn't hear and produces not too much heat. Configure in RAID 1, it is still fast and can write and read at the same time without loss of speed for backup! I now have a backup of my digital archives as safe that I have ever had and I have access to the files as if they were in my internal drive, wow!
