OCZ's Vertex 3: Second-Generation SandForce For The Masses

Benchmark Results: 4 KB And 512 KB Random Reads

The header of these two charts is the same, except for one important detail. The first employs a queue depth of one, and the second uses a queue depth of 32. Why are these figures important? Well, look what they do to performance.

Native Command Queuing, part of the SATA specification, was originally designed to improve the performance of mechanical disks by allowing the hard drive itself to optimize the order in which read and write commands get executed. Of course, the physics of a hard drive don’t apply to SSDs. However, the multi-channel architecture of a solid state drive enables it to similarly field multiple concurrent requests—though Intel claims the bottleneck isn’t the drive, but rather the host system itself. Today’s SSDs are consequently dependent on high queue depths in order to realize the specifications you see manufacturers quoting.

With a QD of one, the Vertex 3 isn't quite as impressive as the Pro model, but this is to be expected. The gap widens with more concurrent requests applied to each drive. Fortunately, while they're plausible for the enterprise space, high queue depths are unrealistic on the desktop. Compared to the previous generation, though, the Vertex 3 shows a marked improvement. We are looking at nearly 215 MB/s to the Vertex 2's 81.2 MB/s.

    SSD prices are really down slow and that is because HDD is still selling.

    I agree and it is time for HDD to be retired. We don't need them anymore, but Servers.

    A far cry as far as "the masses" are concerned. Still, over $2/GB is too much. Getting closer however. I'd pay $200 for a 256GB SSD with these speeds.

    I am sure price will really drop by end of this year.

    mayankleoboy1the fact that they use ~15% of a quad core SB CPU, is amazing.with the mechanical drives, they were just sitting idle. this more than anything, makes the SSD worthwhile.
    Well what I didn't mention in the review is that the benchmark starts as ~20% across all cores during the first 10 seconds, which is from PCMark setting up the disk trace. After that, the IO activity throttles a single core up to 100% for almost all SSDs. For the hard drives, we see ~60-80% utilization of a single core.

    I say keep your desktop active all the time. I am running i980x overclocked to 4.0Ghz and there is no way i will put my computer into any type of power saving mode, it is useless and power saving is just mimick. We are talking about very small amount of money over a year. Having Turbo option makes sense from certain point of view but bottom line is that it is just wasted silicon and pretty much useless.

    "The problem is that any price above $2/GB is going to be a hard sell unless you're an early adopter by nature. Our choices in recent System Builder Marathon stories reflect this. Look at our December $1000 PC."

    Overall a good article. Anyone into MTBF's will find that one page uninforming and anyone not into it is likely lost.

    I would disagree with that statement only in the sense that a $1000 PC is not going to be filled with high-end superior performing parts. So I dont see a reason to apologize for its price. The person who can afford a $3000+ PC isnt going to blink buying the 240G model and will likely see it as entirely reasonable.

    Me? I think I have found my next ex-drive.....

    so as i said, will OC increase the scores a bit?

    and what about power saving enabled?

    None of our tests were executed in an environment that allowed any idling. Furthermore, we disabled CPU throttling. Power saving was enabled in the sense that the display was allowed to turn off, which is part of the default profile in Windows.

    OCing may increase performance, but only to the extent that the bandwidth will support it. As I mentioned, PCMark throttles a single core up to 100%. It isn't a sustained trend.

    on your 1000 dollar gaming system, I'd rather have a vertex 3 than two 460's hell even an agility 2... and still afford better than a 460.

    But then that's me, and to quote the great Inigo Montoya, "I hate wait" and most games I play are not bleeding edge, I also work on my computer, play HD movies and copying time makes me angry when I'm moving files. Buy an ssd, and later spend 60 bux on a 1tb drive down the road.
