I am running a HP p410 in a dl180g6 l5639/8g on server 2008 with the latest drivers/firmware. The drives are 4 samsung f4eg 2tb in raid 5, 128K stripe, with updated firmware. read speeds are good at 322MB/s while writes are terrible at 44.6MB/s. The other raid 5 array on the same controller with 3 segate 1tb drives also shows similarly poor write performance. I was previously running these arrays on a highpoint card in raid 5 with writes around 140 MB/s.
Is there any way to improve write performance?
