See if you can find the Intel Matrix management software for your motherboard either from Gigabyte or Intel. Next, from what I can gather, newer SATA drives designed for "self preservation" aren't recommended for RAID. You need to buy drives specifically for these purposes. It has something to do with some sort of deep cycling or such which happens in the background. RAID specific drives, as I understand, don't do this but are all about "full speed ahead and don't look back". They cost more too. Go figure.
I've been noticing lately that my newly setup system is EXTREMELY slow to respond at times!
for instance if i create a new document or photoshop file.. the moment i click anywhere on the screen the software wont respond.. and the windows performance monitor actually shows the process is waiting on disk operation (writing the temp file)
My system is based on the following:
MB: Gigabyte GA-965P-DQ6(rev. 1.0) with Intel ICH8 RAID Controller, and Gigabyte SATA2 RAID controller
CPU: Intel Core 2 Duo E6600 @ 2.4GHz
RAM: 6GB DDR2 800
OS: Windows 7 Ultimate 64 bit
Drive C: RAID 1 (Mirroring)
2x Western Digital 250GB SATA HDD (WD2500JS-00NCB1)
(The drives are physically connected to port 1 and 2 of the INTEL ICH8 chipset)
Drive D: Standalone SATA
1x Samsung 500GB SATA (HD502IJ 1AA01110), connected to port 1 of the Gigabyte storage controller
Drive E: RAID 1 (Mirroring)
2x Western Digital 1TB SATA HDD (WD10EADS-00P8B0)
(The drives are physically connected to port 3 and 4 of the INTEL ICH8 chipset)
i thought the additional array is adding an overhead, so i booted up with it disconnected (i physically unplugged both 1TB drives, and the volume E disappeared), i also unplugged the standalone drive D from the other controller, bascially leaving the main volume alone.
No change.. performance was still misrable.
i have enabled read/write cache enabled on all volumes, same result.
i ran a benchmark on the arrays (HD Tach) and the results seem pretty okay somehow:
C:, 250GB RAID1 Array:
Random Access: 13.6ms
CPU utilization: 4%
Average Read: 55.6MB/s
Burst Speed: 1908.1 MB/s
D: 512GB Standalone SATA Drive:
Random Access: 14.7ms
CPU utilization: 4%
Average Read: 77.3MB/s
Burst Speed: 166.4 MB/s
E:, 1TB RAID1 Array:
Random Access: 13.7ms
CPU utilization: 3%
Average Read: 83.8MB/s
Burst Speed: 2089.8 MB/s
Actually the reason i decided to post this, is today i had to copy a few files around 4GB in size to another machine
i plugged a memory stick, and the process took over 55 minute to complete!!!
i had the same misrable performance trying to copy the files over the network or even burn them on a DVD.
basically all read and write operations are extremely slow
(once done, the files took 4-5 minutes to be copied from the stick to the other machine running linux and a similar RAID1 setup)
Thanks in advance!
