PCMark 7 Performance
For workloads that are particularly read intensive and small enough to make good use of the on-board NAND, the Momentus XT cannot be beat. The VelociRaptor does come very close however, and it does win in enough other benchmarks to make it clearly the better overall performer. Philosophically I understand why Western Digital opted against equipping the VR with any NAND (cached operations do sort of defeat the purpose of having a 10,000 RPM spindle speed), but that doesn't change the fact that it would've made for one pretty impressive hard drive.
Power Consumption
Despite its 2.5" form factor (the drive itself), the VelociRaptor's 15mm height prevented it from being used as a notebook drive. Even if you had a thick enough notebook, the VR's power consumption is more in-line with a 5400RPM 3.5" drive than a standard 2.5" mobile drive. That being said, as a 10,000RPM 3.5" drive the VelociRaptor is quite power efficient. Idle power is competitive with WD's Caviar Green (and lower in the case of load power).
Power consumption is down compared to the previous generation as well. Once again, compared to an SSD however the drive isn't anywhere near efficient.

Greetings from Palm Springs. I am a old man with money to burn. Then retired, grumby and old fashioned. Still rocking a pristine condition Dell XPS 730x H2C. Typical for Dell replaced almost every proprietary part in it due to failure since my 2009 $5,300 system purchase. WD VelociRaptors (low capacity) were big at the time and I had two of them installed. Needed to replace them as well. But for today I just installed (2) new updated 1TB Raptors for old time sake eventhough much too expensive. Feels like the 2009 XPS 730x is running better with VelociRaptors and not SSD's? But then was does an old man like me know and with bad hearing to boot?
