Now supported by X79 chipsets!

All you need is the IRST driver v11.7.x.xxx or newer!

Thanks ericeod for bringing that to my attention. thumb.gif

Hello there fellow overclockers,

I am a newcomer to this site and have been out of the loop of tech stuff for about 4 years since I was living under a rock. recently I have been doing some intensive researching because I bought my new laptop.

so here is the setup,

it is i73740QM
1TB 5400 rpm HDD
32 gb SSD

Of course my purpose was for caching to boost performance. so upon booting from factory setting, the iSRT interface did show the accelerate tab, I clicked into but click cancel again to jump out to ensure I have the right setting from all components, i then immediately reboot and checked my bios, which it read as RAID, after logging in and opening my ISRT, the accelerate tab when missing.

I did a few things from here on:

i updated to the newest driver after i uninstall the previous ones.

I have switched back to AHCI then reboot, then reboot again to change to RAID, then reboot again to no avail. It still wont show.

out of desperate measure, I checked there aren't any partition on the SSD so I reformat the SSD. Then I restore the system back to its factory state. which the older driver was install, the bios was in RAID mode but the accelerate tab still doesn't show.

I have now updated my BIOS to the latest version too which still doesn't help.

Anyone could help me on this?

Very useful information for those down the path of SSD caching. I'll offer my setup as food for thought for those of you thinking this through.

First off, an SSD cache can only cache 1 volume. This volume can be partitioned like any hard disk, i.e. C, D, E, etc, but the cache can only cache a single volume.

This is an important fact because what if your OS is on the C, and let's say it's a mirror, and then you have a raid0 for games etc... you can't cache them both because in this scenario they are two volumes. Another scenario using IRST is multi volume configuration on a raid set, raid 1, 5, 10, etc. You can't boot to larger than a 2TB volume using MBR so if you make a <=2TB MBR and the rest a GPT, guess what? It's 2 volumes and you can't cache them both!

I solved this issue by UEFI booting to a RAID10 array. I use 4 x 2TB 3gb/sec Seagate Constellation Enterprise SATA drives. This created a single 3.6TB volume which I partitioned C to 500gb and D to 3.1TB. I use a OCZ Vertex4 64gb SSD to cache the entire "volume" (partitioned in this example to C & D), and I get the performance and redundancy of a RAID10 array boosted by SSD caching. As a note: I do not set the cache to maximized, rather optimized mode, because my rig is not a pure gaming rig, and I burned myself once with lots of cross linked files "tinkering" while the cache was set to maximized.

Why 3gb/sec vs 6gb/sec SATA? because Intel only provides 2 6gb/sec ports on most motherboards, and one of those should be your SSD cache drive. I've never seen a motherboard with 4 6gb/sec ports on the Intel controller, only 2 on the Intel and 2-4 on the secondary controller. Also, the Intel controller servicing a RAID10 array on the SATA 3gb/sec ports offers optimized raid set performance. I believe it'll be bottle necked by the drives, not the controller. So I suggest there is no need for a raid10 6gb/sec disk set on Intel desktop raid controllers to date until drive performance gets significantly better, but what do I know tongue.gif

You could of course do the same thing on a raid0 or raid5 with 4 disks configuration, I just use raid10 for redundancy and performance characteristics.

For your information, a pic of my IRST setup, and ATTO benchmark. The cache was warmed up for this benchmark so you see enhanced read performance, when not warmed up the read and writes were about the same performance, and If I was using maximized mode you'd see better write performance.




Happy Caching thumb.gif

Hello Bigchief here. I just recently dropped the bomb on my pocket and bought the intel 520 ssd 480 gigs. What i was wondering is it possible to run RST on two ssds and will there be any improvements. reason being i have an old ocz vertex 2 60 gigs laying around the house and want o put it to some use. Which takes me to my next question can i run two different brands of ssds on RST . thanks if you have any knowledge you want to share.

Sounds to me like you'd be slowing down your nice brand new blazing fast 480gb SSD with a slow 60gb SSD. The smaller SSDs are slower in general even in same product line, adding an older generation 60 to the mix sounds pretty bad.

uninstall IRST from your system.

Try this driver installer: www.station-drivers.com/telechargement/intel/sata/intel-rst_12.0.0.1083(www.station-drivers.com).exe

Hi all!
Yesterday I bought wd 3tb red hdd, and then I tried to install everything, so this is what I did and where I stuck:
- put the option in BIOS from AHCI to RAID
- went to windows 7 installation, where it only showed that hdd have 746gb
- then I tried formatting it to GPT in Ubuntu GParted, and win was the same, but I loaded IRST drivers to it and then it showed - 2000gb and 746gb separately
- I couldnt partition any of these two volumes, and then I tried anotner win 7 disc, which couldnt show me my hard drives and I couldnt load drivers for it
- after that I tried with formatting hdd to GPT and setting it to NTFS
- it showed as full drive but I couldnt install windows to it
- so I deleted the partition, and I could partition the volume
- I started with installing but it stucked at 0% and got some error that it cant install for some stupid reason...
Any ideas what I can try, or doing something wrong?
Tnx!

Sean...My Apologies for duplicating the question here: I've been searching for the past 8 hours...my head is spinning. I'm building with a 256 SSD for the OS and a 2TB for data storage. Is there a configuration that enhances data transfer and read/write using IRST?

Do you know if IRST is better than Asus SSD caching when using Marvell Controller?

I've been trying to set up IRST all night. I installed my OS with SATA set to ACHI, then read your articles, changed it to raid, and loaded IRST....but never saw my drives available for accelerating.

After reading so much, I'm not sure it's even worth it.

Thanks for your help.
