Intel SRT SSD Caching performance issue/degradation over time

idata — Sat, 17 Mar 2012 06:37:59 GMT

Hi,

I have a problem with intel SRT feature.

I have HDD disk D:\ that is accelerated with SSD disk.

After PC reboot the speed of cached disk D:\ is ~500 MB/s with ATTO bench.

Then after some time (day or two) the cached disk D:\ performance degrades to the speed of the HDD (~150 MB/s).

Status in intel SRT console is OK.

After PC reboot the speed of cached disk D:\ is again ~500 MB/s.

Some data:

- Caching is set to enhanced

- The size of SSD is 60 GB Corsair force 3

- Motherboard is Asus P8Z68-M PRO

This is what I tried to fix(doesn't work):

- I tried to use ALL for Caching

- I tried to use only 18 GB for Caching

How can I fix the speed problem without rebooting every time?

Thank you
