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.

    I admittedly only did a quick read of the article so I may have missed it, but were there any comments on noise and vibration compared to previous VelociRaptors and other mechanical drives?

    My Raptors have always been smoother and quieter than other drives. I have 2 of the first-gen 2.5" mounted on the 3.5" form factor heat sink, and I can't even tell they are running, except to see the drive light on the front of the computer flicker (and, of course, the computer is running properly).

    I agree with the conclusion... "if I needed to buy a high-performance mechanical hard drive, it's the one I'd pick."

    I always had a raptor until SSD became affordable to me (about the time of the Vertex2's release). With a 120gb Vertex 3 drive currently $139 after $20 rebate at Newegg, why bother?

    Use the SSD as your OS and apps and several of your favorite games and a large cheap HDD for storage, movies MP3's old games, etc - things that don't need fast access. 120gb is plenty big for that. My Vertex3 is set up that way and has 50% space free still. Fast as hell.

    Is so fast it doesn't even allow the Win7 colors to touch on the launch screen. Before the 4 colors swirl and then come together and strobe, its it Windows. sigh...

    Anybody know how the multiple drive setups will work under Win8?

    Apparently the Drive Extender from the original Windows Home Server (which was ripped out of the sequel) is part of Windows 8. What kind of control will be available concerning which files go where when using this in Win8?

    It's irresponsible to recommend the Vertex 3.

    It's irresponsible to recommend OCZ products, period. Their strategy of bringing products to market six months early, then using their customers for the validation phase has long since shown its true colors. Combine that with a policy of ridiculing anyone who dares question them has turned me from a customer to running away from anything they produce.

    I have somewhat mixed opinions about Vertex 3's since we upgraded to them at work. Probably about 50% extra cost hidden in the man hours wasted trying to sort out firmware, and we're still not completely BSOD-free. The price has come down and they're fast, but not faster than my problem-free Intel 510.

    But to generalise to all OCZ products is unfair. My reapers are still great after 4 years, and the SSD bugs are partly down to Sandforce.

    LOL, it's irresponsible to recommend ANY OCZ SSD ;)

    Access time?
  • Scott314159 - Monday, April 16, 2012 - link

    I think there is still a role for the raptor in the budget server market where enterprise SSDs are still too expensive. While in the consumer SSD space confidence and longevity are still not where they need to be (any disagreements or counter arguments with references??).

    I will probably use these drives in my next server build...
