Intel ICH10R RAID help...

post #1 of 3
Thread Starter 
Hey guys, im having some issues with using the Intel ICH10R RAID controller on my Rampage III Gene. After reading over an overwhelming amount of data regarding disk alignment, stripe sizes, etc, i feel rather lost.

What stripe size should i use (2GB to 50GB files utilized) and is alignment in Win7 x64 an issue? Is the cache on the (circa 2007) laptop hard drives i have the source of my slow write times? I back up data regularly; this is purely for performance. I know they *should* be able to write much faster; and thats what im after. Same with read times; they seem slow as well.

Without needing to get into the technicalities (listed below), i have 2 RAID 0 2-disk configurations, each set as 128K (drives 1 and two, below) on the ICH10R Intel RAID controller, as well as a pair of Blu Ray burner drives, which are NOT in use during any stressful hard drive activity.

I am used to using separate RAID controllers, and only dabbled in on-board RAID; im looking for the optimum setup for my system and would LOVE some help! I will try to be as technical and precise as possible. I am fairly knowledgeable about computers, but this is the first time i have tried to tweak on-board RAID, as i donated my own RAID controller to my business so we had two identical editing machines.

The system is a Core i7 950 at 4.07Ghz or 4.3Ghz with 12GB RAM at 1510Mhz, 8-8-8-20 timings, running Windows 7 64-bit Ultimate, so it is more than capable.

I have twin Intel X25M 80GB SSD's on the Marvell SATA III controller in RAID0; performing flawlessly around 370MB/sec read and 140MB/sec write; im more than happy with that.

I have played around with Intel RAID (and quickly abandoned RAID0) on an ICH9R board. At work, we have ARECA RAID controller cards, but i like to do some work (HD video) at home, so a RAID setup would be nice to have. I need at least 4 logical drives for optimum performance with Adobe CS5, hence i have them split into RAID0 drives and additional USB 3.0 drives.

However, on the Intel SATA II ports/controller setup, im having consistently low read/write speeds. Here are the setup specs... I got the laptop drives for $35 a pop a month ago (all are identical models, firmware, buffer, speed, etc), and i have 2 spares. i tested read/write speeds on all 6 and they all check out just fine.

I have only 4 of them installed on my home machine (2 are spares because the Pioneer blu ray drives take up 2 SATA II ports). They read around 220MB/sec high, 170MB/sec low in a 2 disk RAID 0 array. Write speeds are around 120MB/sec high, 80MB/sec low; seems low to me... Both RAID o hard drive arrays are 128K (due to working with 2GB-50GB files regularly). The Rampage III Gene motherboard has no Ultra ATA (ribbon) cable interface, so i went with SATA disk drives.

Drive 0 - 2X Intel X25M in RAID 0 on Marvell SATA III, Windows 7 64 bit, CS5 suite and all software

Drive 1 - (intel ICH10R 2 disk RAID 0) Media/projects

Drive 2 - (intel ICH10R 2 disk RAID 0) Pagefile/Media Cache

Drive 3 - Preview files - OCZ Enyo USB 3.0 128GB

Drive 4 - Export files - OCZ Enyo USB 3.0 128GB

RAID 0 configuration...
Port 0 - Intel X25M 80GB SSD
Port 1 - Intel X25M 80GB SSD

Intel ICH10R SATA II

RAID 0 configuration... Intel ICH10R
Port 1 - Fujitsu Lifebook 80GB 2.5" 7,200RPM HD 8MB Buffer
Port 2 - Fujitsu Lifebook 80GB 2.5" 7,200RPM HD 8MB Buffer

RAID 0 configuration... Intel ICH10R
Port 3 - Fujitsu Lifebook 80GB 2.5" 7,200RPM HD 8MB Buffer

Port 5 - Pioneer BDR-206 Blu Ray burner
Port 6 - Pioneer BDR-206BK Blu Ray XL burner (arrived yesterday!)

I also have 5 1TB USB 2.0 drives as backups, so i am not worried in any way about losing data; just want to make sure i am getting optimal disk performance for CS5 work. I am using Harm Milaards' guidelines for my disk setups

What does a single 80GB lifebook bench? Your 2 disk raid0's should be going around 190 to 195% of a single drive. Windows 7 should align itself correctly and you'd want the largest stripe for large files.
