PCMark Vantage - HDD Score : 77278
CrystalMark Sequential Read 1045.61 MB/s Sequential Write 940.61 MB/s


PCMark Vantage HDD Score is same as single drive. I think it?s software issue.
CrystalMark still has almost double speed.

IOMETER 2008
1 minute - 100% Read / 100% Random 4KB
Total I/Os per Second => 75398.85


3 minutes - 100% Read / 100% Random 4KB
Total I/Os per Second => 68926.28


IOMETER 2008 Random Read 4KB increases 24~35%.
1 minute to 3 minutes later, the performance drops 9%.

1 minute - 100% Write / 100% Random 4KB
Total I/Os per Second => 112569.77


3 minutes - 100% Write / 100% Random 4KB
Total I/Os per Second => 112823.49


IOMETER 2008 Random Write 4KB increases about 23%.

SSD Benchmark TOTAL => 7455.18


This software also increases 48%.

Windwithme mentioned several times when sharing SSD Raid 0 test.
That moment, Intel Rapid Storage Technology didn?t support Raid 0 Trim mode. So the speed would drop after using for long time.
Few months ago, Storage Technology Drive 11.5 released and official support Raid 0 Trim.
This is really a good news for Raid 0 mode users.
It also pushes SSD further performance and applications to wider range.



SandForce SF-2281 controller has been launched over 18 months.
From high end SATA3 SSD position to current 80% market share, the price is close to entry SATA3 SSD.
As different service terms and warranty, the price is different.
Popularity and price is SandForce strength. The weakness is random write beginning is risng from 200 more MB/s to 500 MB/s slowly.

This time, CORSAIR Force GS uses different NAND Flash ICs. Some performance is improved a little.
As Max Random 4k Write (IOMeter 08) over 90k IOPS (4k aligned) is the major improvement.
This article shares you the different performance of SandForce SF-2281 controller with different NAND Flash.
Also, Intel Rapid Storage Technology Drive high performance in Raid 0 mode.
You can use it as your reference for further SSD purchasing. :)
