Hi all, wondering if any of you could shed some light on a problem I'm having.
I have a Gigabyte GA-EP35C-DS3R motherboard with the Intel ICH9R RAID chip on it. I have Raid 0 set up over 2, 250GB Western Digital HDD's, the 2500AAKS model. RAID is set up with default values, 128kb stripe.
However, I get HORRIBLE write performance. According to FreshDiagnose, I am getting 9.36MB/s. It's so slow my computer starts jerking on boot up and when doing HDD intensive things (running VM)
Read speed is fine, rated at 169MB/s in HD Tach (and 2250MB/s burst speed???)
I have updated the Intel chip's drivers to the lastest version from Intels site, 7.8, and have updated the BIOS to the latest version, with absolutely no performance increase.
If I put on write back caching, I get to around 14MB/s but this is still bad.
Even when it was working, I didn't find it much faster in practice.
I used a hard drive benchmark back then and only saw a 5-10% increase in performance but that was a few years ago and the current generation of RAID chips and/or hard drives probably perform better now.
