"They deliver up to 60% higher sustained sequential throughput than previous generation Adaptec controllers and up to 2GB/s sustained data transfer rate to the host."
•Direct IO
All read data is transferred directly to host memory bypassing RAID controller cache. Any Read Ahead data is cached.
All write data is transferred directly from host memory bypassing RAID controller cache if Write-Through cache mode is set
Recommended for all configurations
•Cached IO
All read and write data passes through controller cache memory on its way to or from host memory. Includes write data in Write-Through mode.
•This legacy option is being eliminated in a future release
我覺得他的測試結論待保留..
我不清楚為什麼他的測試結果是這樣..
不過作RAID的目的是:
1. 從最大傳輸率增加
2. 從整體的Seek Time,Access time 減少(非指單顆..)
他那個HD Tune測出來的Access Time(RAID過後對於Access Time, HD Tune應該是不會有太大變動..)...
結果是很奇怪的...
因為剩下需要改善的僅能從固件去增強...
你確定你的固件版本??
看能不能刷LSI的固件??
