Unfortunately, we can’t be that enthusiastic about Western Digital’s Velociraptor Duo at $900.
Gigabyte Z77X-UP5TH scorecard
Pros:Last-gen, no holds barred Z77 motherboard.
Great feature set including x2 thunderbolt ports, x4 6Gb/s SATA ports and x10 USB 3.0 ports.

Good layout and construction.
Cons:A tad expensive, even for what you’re getting.
Cons:Very expensive and not a great value versus SSDs.
For more capacity, WD’s own Thunderbolt Duo might make more sense.
