OCZ Vertex 3 Preview: Faster and Cheaper than the Vertex 3 Proby Anand Lal Shimpi on February 24, 2011 9:02 AM EST
Faster than the Vertex 3 Pro?
SandForce’s specs put the SF-2281 at up to 500MB/s reads and writes, just like the SF-2582/2682. OCZ’s specs for the Vertex 3 however put it slightly above the performance of the Vertex 3 Pro:
I asked SandForce to explain the discrepancy. It turns out that SandForce doesn’t really enforce its specs on its partners. It’s up to the partner to test and advertise whatever it would like as long as it can back those claims up. In this case, the Micron 25nm NAND appears to perform a bit better than the 32nm Toshiba NAND that was used on the Vertex 3 Pro. As a result, sequential write speeds are slightly higher.
OCZ also rates the Vertex 3 as having slightly lower random write performance than the Vertex 3 Pro, but the difference is not that great in practice.
For desktop performance this does mean that the Vertex 3 will likely be a bit faster than the Vertex 3 Pro we previewed a week ago. You trade off enterprise level features for price, but you don't sacrifice performance.
I'll point out once more that this is beta hardware running beta firmware. I've only had the Vertex 3 for a matter of days before publishing this and that's honestly not enough time to put it through anything more than a handful of performance tests. Real reliability and bug testing will take weeks if not months. Keep that in mind if you decide to be an early adopter on one of these drives.
