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

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.

    That $1000 build sucks out loud. SLI is a worthless technology and those graphics cards are old. You could easily swap the crappy SLI setup for a single GTX 560Ti, step down to a 500W PSU and add a Vertex 2E for ultimate Windows performance and super fast game load times.

    Why would you even talk about GPUs? This is supposed to be a test for SSDs.
