我在RAID 5配置中使用英特尔快速存储技术配置了5个2TB Seagate SATA磁盘。
我对Read性能感到满意,但写入性能非常差。
希捷规格。
在单个磁盘上显示210 MB / s的最大持续传输速率。
我意识到RAID 5配置有一些开销,但31.85 MB / s顺序写入太低。
有谁知道如何提高我的RAID 5阵列的写入性能。
谢谢您的帮助。

I configured 5 2TB Seagate SATA disks using the Intel Rapid Storage Technology in a RAID 5 configura
tion.
I am pleased with the Read performance but the write performance is very poor. Seagate Specs. show 210 MB/s max sustained transfer rate on a single disk. I realize there is some overhead with the RAID 5 configuration but 31.85 MB/s sequential write is too low.
Does anyone know how to improve the write performance of my RAID 5 array.
Thank you for your assistance.
