SandForce Performance Differences

To best illustrate how SandForce SF-1200 series SSDs perform against each other, we used several different products that contain the SF-1222 storage controller to demonstrate relative performance levels. Each SSD was given the exact same preparation prior to testing, and all benchmarks were conducted on exact same system and drivers.

AS-SSD Benchmark

While the 4K 64-thread read-from results varied slightly, the write-to results were all nearly identical. Displayed in the chart below, the 64-thread 4KB IOPS performance results for several enthusiast-level storage products illustrates which products offer the best operation under load:


ATTO Disk Benchmark

Peak read and write performance was identical for all SandForce SSDs using ATTO Disk Benchmark with a default queue depth of four. The chart below does an excellent job of illustrating where the SandForce SSDs are positioned in terms of bandwidth speed.


CrystalDiskMark 3.0 Tests

Displayed in the chart below, the maximum 4KB queue depth 32 IOPS performance results for several enthusiast-level storage products illustrate which products offer the best operation under load:


Iometer IOPS Performance

To measure random I/O response time as well as total I/O's per second, Iometer is set to use 4KB file size chunks over a 100% random sequential distribution at a queue depth of 32 outstanding I/O's per target. The tests are given a 50% read and 50% write distribution. While this pattern may not match traditional 'server' or 'workstation' profiles, it illustrates a single point of reference relative to our product field. Our chart below illustrates random Read and Write IOPS performance over a 120-second Iometer test phase, with the average displayed in our benchmark results where high I/O is preferred:


Up until this point, the SandForce SSDs have been either identical or roughly similar. Clearly, the Corsair Force F100 SSD has separated itself from the crowd by performing at nearly twice the level of the other SF-1222 SSDs. In our next section, we take a closer look at the firmware versions and explain why the focus on firmware could mean more than performance.



# SF1500 ? and others tests ;)Federico La Morgia 2010-06-03 22:49
I saw on the website that there is a version of sandforce SF1500 enterprice class, you know if any SSD on the market uses to be able to test since SF1200/1220?

A tip, there is some PCI-Express RAID controller that supports RAID SSD without disable the TRIM command and other commands that provides the sandforce and has at least 8 channels like normal RAID controllers from 300-1000 euros?
Because it would be interesting to test 8-10 SSD with RAID controllers with Sandforce 0-1-5-10-50-60-51-61 doing many tests including those that completely filled and completely empty the resulting volume in order to understand how deteriorate the overall performance over time!

I understand that now I hate the fact that I beg you to do many more tests, some seemingly strange, but I think it could bring to light strengths and weaknesses nasconti that would not normally go out :)

So the manufacturers are marketing SSD's with known bugs and flaws in the firmware (1222), and it's up to the buyer to upgrade the firmware to get the SSD to work properly, OR IT DIES???

This has a bad smell!
