What am I doing wrong that I can't get my SSD to read and right  over 250mbs with HD Tune and Atto bench program. I have my SSD on 3.0 sata cable and I even bout a a PCIE sata 3.0 6gb controller card, but I still can't get past 250mbs. Any help would be cool. I am running windows 7 64 bit. 7gbs 6400 ddr2 memory. 1000w power supply. GeForce 560 ti video card. A biostar p43-a7 mother board. Intel 3.0ghz core 2 duo processor. 120gb OZC agility 3 SSD.

You may be otherwise limited i.e. cpu limited.. Was it a significant upgrade in the speed you were getting before?

This benchmarking review shows your drive is about right for that model: http://benchmarkreviews.com/index.php?option=com_content&task=view&id=762&Itemid=60&limit=1&limitstart=6

I'm guessing you are benching the same SSD you are booting from.  If so, then you are getting much more I/O then you give the SSD credit for.  The benchmark isn't factoring in everything else that is going on in your computer. It is only measuring the benchmark I/O.

If you want a decent benchmark, you need to boot to another O/S and not mount the drive and run raw I/O at physical device.  Based on this premise, the numbers you are getting are perfectly reasonable.

Wow Davis that is what mine does show. On new egg it says it can do this.

Performance
Sustained Sequential Read
up to 525 MB/s (SATA 6Gbps)
up to 280 MB/s (SATA 3Gbps)
Sustained Sequential Write
up to 475 MB/s (SATA 6Gbps)
up to 260 MB/s (SATA 3Gbps)
MTBF
2,000,000 hours

But like dlethe said I am not think about the fact that it is my OS. so I think it is running great in that case.  Thanks guys.
