Hi there, I have 2 x Intel S3520 480GB in raid 1 on a M5016 raid card with Write Through, No Read Ahead, Disk Cache Enabled and after 4 months the write is still the same but the read slowed down. I have tried every setting that I could think of... I even formatted the drives again and still no luck with the reads.
