64K - Write - Average 336.7 MB/s Access Time 0.143ms
1MB - Write - Average 331.4 MB/s Access Time 0.108ms
Read - Random Access & Extra tests
Write - Random Access & Extra tests
Sequential 4KB randon Read - 66732 IOPS / Write - 91984 IOPS
ATTO DISK Benchmark over 512KB test, max read is 557.9 Mb/s and max write is 535.6 MB/s
Seq Read - 524.1 MB/s Write - 288.7 MB/s
<All 0xFF, 0Fill> Read - 527.4 MB/s Write - 524.9 MB/s
<All 0x00, 1Fill> Read - 527.6 MB/s Write - 525.1 MB/s
CrystalDiskMark default test is random. You can see right side performance is lower.
It?s characteristic of SandForce controller. It has lower performance in random algorithm.
Left pic is CrystalDiskMark sequential mode. The write performance is close to official specs.
AS SSD Benchmark - 811
Seq Read - 519.43 MB/s Write - 274.13 MB/s
4K - 64Thrd Read - 224.70 MB/s Write - 214.04 MB/s
AS SSD Benchmark Seq Write is similar to CrystalDiskMark.
Compression Benchmark write starts from 280MB/s to over 480MB/s.
SandForce in Sequential Write uses special algorithm, this is key weakness of SandForce controller.
In sequential or random read, 4K performance and continuous write, SF-2281 controller is very good.
PCMark Vantage - HDD Score : 78671
CrystalMark Sequential Read 503.02 MB/s Sequential Write 500.48 MB/s
1 minute - 100% Read / 100% Random 4KB
Total I/Os per Second => 55773.68
3 minutes - 100% Read / 100% Random 4KB
Total I/Os per Second => 56190.92
1 minute - 100% Write / 100% Random 4KB
Total I/Os per Second => 91791.99
