Hello everyone!

I've been using SRT successfully for a number of years and have seen benefit from it caching a 1TB Seagate barracuda drive with a 64GB OCZ Vertex SSD. However, after the recent Windows 10 creators update, it seems that the SRT isn't actually kicking in despite the UI and OROM showing that acceleration is configured successfully.

I have an ASRock Extreme 4 (Gen1) Motherboard, which is a Z68 chipset. I'm using 12.9.4.1000 RST(e) drivers in Windows and have an Intel 10.8.x OROM and latest BIOS. Everything is set up properly, I have the 1TB drive accelerated in Maximized mode and the IaStore UI shows that everything is good to go, but crystalmark/hdtune file benchmarks with all zero file and multiple passes shows no benefit for sequential or 4K read. I've tested with the acceleration turned off and get the exact same speeds. I mainly use the large drive to store games and use the acceleration to speed up the loading times/etc. This definitely used to work, but now I have objectively measured the app loading time on reboot (so it's not cached in RAM) and it clearly isn't using the SSD cache even though I have launched the same app many times. The loading times are noticeably slower than before when the cache was working (about double).

I store my OS and critical programs on a separate OCZ drive (identical to the one I use for my cache drive) and all benchmarks for that drive show great speeds with no issues. I have attached several screenshots showing this.

Drive Info (Cache disk, accelerated disk, system boot drive):








Just wanted to check if anyone else with a Z68 has actually noticed SRT kicking in on Windows 10 (specifically with creators update)? Maybe I'm missing something simple here or am I just SoL and should just go buy a big SSD/migrate my data over since this doesn't work anymore?

I know the OROM is an older version, but I don't believe it should matter since I'm not booting off the accelerated drive and none of my disks are > 2TB.

Thanks,

Hello Fernando,

Thank you for the reply! Of course, using the two in raid0 would have been faster, but at the time (about 6 years ago) when I was building the system I wanted something where I could play a lot of different games and not have to worry about manually creating symlinks or installing certain games on the raid array due to space constraints. At that time larger SSD's were also much more expensive.

Intel RST seemed like a good solution since I could store my steam library (~400GB+) on the 1TB drive and RST would take care of automatically using one of the SSD's to cache my most played games and I would get SSD performance for loading levels/etc without any manual intervention/moving games around or making symlinks. Basically, set it and forget it.

Initially when I was on Windows 7, it worked just fine and did exactly that. However seems that ever since I upgraded to Windows 10 it just stopped working despite UI saying everything is good.

I tried the 13.2.8.1002 driver, but it still doesn't seem to be working. I removed/re-created the accel config and everything, but no dice. Again not sure if this is a problem for me specifically or just that SRT with the z68 chipset doesn't work anymore on Win10 (was hoping someone else that still has this old chipset may comment and you could add it to your notes).

At this point large SSD's are so much cheaper that I just went ahead and ordered an 500G 850 EVO and will just use that for my boot and main storage and RAID0 my two old OCZ vertex2 drives ( which will still be slower than the EVO by itself ) for some additional storage.

Again, thanks for taking the time to respond!

Regards,

Gene

Have you tried updating RAID OROM/EFI to 12.9?
