AS-SSD High Queue Depth Incompressible Sequential Performance
The AS-SSD sequential benchmark takes place at a very high queue depth of 32 and uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.
For all intents and purposes, worst case sequential read performance is identical between the Vertex 3 and Intel SSD 510.
While ATTO showed us the Vertex 3 with a signficant advantage over the 510, AS-SSD gives us the other end of the spectrum. If you're going to be copying a lot of H.264 movies around on your SSD, the 510 will likely have better write performance than the Vertex 3. However if you're copying large databases around instead, the advantage will shift back to OCZ/SF.

Article says "Write speed with fully incompressible data is easily a victory for the SF-2200 based OCZ Vertex 3. "I think you meant "Write speed with compressible data is easily a victory for the SF-2200 based OCZ Vertex 3. "
Excellent article, I was interested in the 3rd gen intel SSD, but not at these specs. Wish you gave the read latency time (it can be inferred to some degree from the elapsed time charts which are good). Also, given the size of internal cache these devices use perhaps running for more than 3 mins would be a good idea. The average performance is still changing at 3 mins.

"I mentioned earlier that the 510 would go through Intel’s extensive validation testing, just like any other Intel product."Yea right! Just like the H67 and P67. Yea, that made me so happy.

That's 100% a valid point and it does show that even with extensive validation errors can still get through.You'll remember that the X25-M was the first to have major firmware issues before any of its present day competitors were even created.
Only time will tell how well Intel has learned from those experiences and how seriously it's taking the validation of the 510. Initial compatibility testing looks good but we've got a long road ahead of us.
Take care,
Anand

At least Intel's labs identified the problems themselves, disclosed the problem themselves, will recall and exchange to fix the problem.These things makes me feel very confident to buy future Intel products.

A good point. Unlike certain NVIDIA mobile chipsets.Chloiber - Wednesday, March 2, 2011 - link
...I think Anand is right. Many of you are complaining, but as he said on the final page: it is not clear, where the actual limits are for random speeds. Of course, it's always better to have more. The thing is, that your PC at home can't benefit from 60'000 IOPS. It just can't. You can run it through benchmarks which show high numbers, but as soon as you feed the drive and the CPU with real data, the drive is NOT the limiting factor anymore.I'm not saying that it's a good thing the Intel 510 has such low random speeds, compared to other, even older drives. But in the end, the question is whether or not you can actually benefit from 200MB/s random reads and random writes with QDs above 4.
Anand said himself, and I assure you that he is correct - you can trace it yourself if you want - that with standard workload on home desktop PCs, Queue Depth rarely exceeds 1 or 2, especially not with an SSD in your system. Not even during boot!
And now THINK AGAIN. What are the random 4k read speeds for low QD of EVERY SSD today? It's actually limited by the NAND being used and it's between 20MB/s and 30MB/s for EVERY SSD.
Again, I'm not saying that high IOPS aren't important. I'm just saying, they aren't as important as you think. Not anymore, not in the very high regions we are today and especially not with very high QDs.
The 510 seems to have very good performance in real world benchmarks - it seems that most of you rate synthetic benchmarks higher than real world benchmarks. This, I don't quite understand.

The fact is, you will not be using a very competitively priced 250GB SSD for net browsing. When I get my SSD, I'll be using it to store my test VMs where I do a lot of software installations and snapshot jumping.The 510 is not a mainstream product where the QD rarely goes above 2. Not at that price at least. I've installed an SSD for a few average users but they were all 60GB drives. I could never justify the price of a 250GB SSD to them but a pro user might (i.e. someone who might make use of a high IOPS drive).

Meant to say "uncompetitively". Too expensive for the average computer user.tno - Thursday, March 3, 2011 - link
Spot on, and so a mainstream drive this is not. As workstation drive, however, this seems pretty solid.Nentor - Wednesday, March 2, 2011 - link
If it (the 510) was very cheap everything you say makes sense, but since it is not they'd better make it as fast as possible.
