T530 Intel SSD 520 Freeze Issue Win 7/8

Question

I've tried asking Lenovo support, however I'm yet to receive a reply. The other concern is that now that I know more, which may speed the reply, I'm unable to update the support request, which is annoying that such a feature is missing from the support system!
Anyway, I thought I'd try this forum to see if anyone else is having/had this issue, and may be able to help.
The issue: Widows 7/8 Freeze often for around ~30 seconds. 
In Win 7 - Event viewer says "\Device\Ide\iaStor0 did not respond within the timeout period"
In Win 8 - Event manager says "Reset to device, \Device\RaidPort0, was issued."
After doing much research on the Internet, it would seem that this is a common issue with some SSDs and Intel's controller. The issue, in my case, is that Win 7 and 8 freezes when configured to use HIPM and DIPM, though I'm not sure if it's both or only one. In Win 7 I was able to use a registry hack (I say hack because I should have to resort to this to get it to work) to make Intel's SATA AHCI drive work. However, I wasn't able to use this same method in Win 8 as the new driver is slightly different and I can't find the necessary information to know how to implement it properly. You think that considering the SSD, chipset, and driver are made by Intel it would work, right? WRONG

I have found a work around in Win 8, but I consider this not good enough, because I feel that all that should be required is for me to install the "Intel Rapid Storage Technology Driver" from the Lenovo support page and that should be it, the device should work. There should be no need to a registry hack or lose many hours trying to make it work - simply, not good enough!
Reference: The work around I have for Win 8 is:
Remove Intel's "Rapid Storage Technology Driver" in favour of MS's generic version
Applying another registry hack to enable MS's power manger to show the HIPM and DIPM options
Disable HIPM and DIPM

Answer 1

I would not think so.
My understanding is that it's more of a powersaving feature than anything else. I beleive HIPM and DIPM simply stands for Hardward Initiated Power Manager (Internals request power off for the sata bus), and the other Device Initaited Power Management (HD requests power off for the sata bus).
