Conclusion

Announcement: Despite the circumstance that the rating of a product is based on as many objective facts as possible there are factors which can have an influence on a rating after publication. Every autor may perceive data differently over time whereas one possible reason for example is a deeper background knowledge or understanding of certain processes. Certain unforseen market conditions as well as changes have the potential to render a descision made at a certain point in time obsolete.

A closer look at the sequential thoughput rates reveals that this drive offers some serious performance. Regarding sequential reads we se a maximum value of 541 Megabytes per second. Concerning sequential writes the drive tops out at 523 Megabytes per seconds. When it comes to random IOPS we measured almost 51'000 IOPS for 4k random reads and aobut 75'500 IOPS for 4k random writes. On the box of this drive you can find that it should be able to perform 555 Megabytes per second when doing sequential reads and 525 Megabytes per second when it does sequential writes. During our tests we haven't been able to confirm these values but we found that they are very close to what the manufacturer promises. Furhtermore you can also see that the sequentials are very stable and robust. Already 32k block size the reach the maximum throughput.

It doesn't matter if you look at sequential or random performance, the toggle NAND flash - which in this case comes from San Disk - that is being used, gives this drive the last bit of speed which is needed to keep up with the very fast single controller drives available these days. Toggle NAND flash really suites best to SandForce's SF-2281 controller.

Last but not least our recommendation: if you're looking for a very fast SandForce driven solid state drive, the Force GS from Corsair will be a great choice and you can be sure that you'll do nothing wrong. These days you can find the for 221 Euros (est. CHF 265.-) on the price comparison portal Geizhals.at. With this price tag, the drive isn't a bargain, but compared to drives with synchronous NAND flash toggle NAND is simply more expensive.
