I've been installing raid 1 based server and the first time i did it. I didn't know which one to choose to I chose at random (I think ICH7R/DH one). Everything worked, but disk access times were cosmic (around 20ms). I immediately realized the driver was wrong, but i couldn't find any reference as to what each of those "ECH7XXXX" mean or what they are for.
So here's a small list of drivers, could anybody tell me what the difference between them are and what they are for? Also, what do tose "MDH" and "R/DH" mean?
- Intel(R) Desktop/Workstation/Server Express Chipset SATA RAID Controller
- Intel(R) Mobile Express Chipset SATA RAID Controller
- Intel(R) ICH7MDH SATA RAID Controller
- Intel(R) ICH7R/DH SATA RAID Controller
I am using Asus z77-a motherboard, 2 ssd drives (that by the way give great speeds apart from access speeds in this setup). ALso I am using Win XP with F6 instalaton. The list of drivers I left are ones provided in Asus website, so I don't think any of them are built for wrong hardware, i just suspect they malfunction because wrong ones are installed.
Another thing i might add is: the reason I am even bothering with this is applications that should take seconds to start are taking a half a minute or so and that's long past the possible mirror build time, because before my current installation the PC has been running for several days.

. Although after instalation I tested access speeds twice and got 16 and 20ms – Zero – 2015-06-12T09:27:43.410Check the event viewer to see if there's any faulty conditions (both errors and warnings) report by the RAID controller. – cheong00 – 2015-06-12T10:14:13.977
A lot of print related errors and a few time sync errors, but nothing even remotely connected to motherboard, RAID or storage. I mean the PC works and SSDs work (and are setup as a single volume through bios), everything works without a single visible error or sign of corruption (I used several diagnostics tools and drives didn't show any signs of corruption), apart from the slow data access speeds. – Zero – 2015-06-12T10:39:26.327
I'm unable to figure out the problem then.
If Intel RST encounter error will create log in event logs. I was suspecting there are error in the SSD's controller so it's access mode is degraded. (Some old memories regarding DMA and PIO modes) – cheong00 – 2015-06-13T01:25:26.587
