I've been trying to resolve this situation for some weeks now...
I have the following set up with a V4 on port 0 and a WD HDD on Port 1.
MB: ASUS P8H61-MX USB3
GPU: AMD Radeon HD 7770
I'm experiencing incredibly slow to non response from the SSD; with windows 8 new task manager you can see the utilisation for the drive is frequently at 100% for long periods, the latency is over 1000ms and the transfer rates are terrible. I know its a cheap SSD but I do not believe its ment to be performing in this way...!
This setup was intended to use the SSD for the system only... i've tried a number of things to mitigate the situation:
- ensure plenty of free space (11GB +)
- performed Trim
- left running idle for long periods (for garbage collection)
- disbled indexing
- transfered the pagefile to D
- installed all latest drivers
I've yet to try disabling LPM because the newer versions of Intel RST have iaStor, iaStorA, iaStorF and iaStorV under
