File Benchmark
Sequential 4KB randon Read - 66732 IOPS / Write - 91984 IOPS
ATTO DISK Benchmark超過512KB以上測試時就達到最高讀取557.9 Mb/s，寫入535.6 MB/s


CrystalDiskMark
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預設測試為隨機測試，如右圖在寫入的數據會偏低
主要是因為SandForce控制晶片的架構特性，在隨機的演算方式會碰到偏低的狀況
左圖CrystalDiskMark測試改為兩種純粹循序模式，寫入表現就可以接近官方規格的數據

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在Seq Write測試項目應該與CrystalDiskMark類似
Compression Benchmark寫入是由280多MB/s開始往上提升，最後超過480MB/s的效能
SandForce在Sequential Write使用特殊的演算方式，這也是SandForce控制晶片在效能上較弱的部分
在連續或隨機讀取、4K效能與連續寫入是SF-2281控制晶片較為拿手的強項
