I also solved this problem by setting ACHI link power management to 'Active'.

Yes I too have a freezing issue. It stops for some 20 seconds before resuming. I have SATA2 mobo - ECS A780GM-A V1. Perhaps this isn't part of the sata 2 standard? Have set AHCI to Active and will see how I go ta.

Setting the AHCI to active has helped to get rid of the freezing (thanks to this thread), however, now my laptop (Toshiba T215D-1150, Windows 7) seems to be too active: the fan is constantly running and the battery drains much more quickly even if no program is running at all. Has anybody had the same problem? Any thoughts?

Thanks for your fast reply. I checked the processes in the task manager first thing after I had realized how hot my laptop runs. But there is no obvious (i.e. clearly visible) process that sucks CPU power. I also checked if my drivers are up to date but they seem to be fine. I installed speed fan to see what the fan does but although I can see core, HD, and CPU temps, I don't seem to be able to get a reading for fan rpm and control that. The only thing I did was following the instructions here (http://www.sevenforums.com/tutorials/177819-ahci-link-power-management-enable-hipm-dipm.html) and installing the AHCI Link Power Management registry changes. Just out of curiosity, did you (all) install fresh systems on your SSDs or went the clone-route?

i have added an ASUS USB3.0 / SATA3 6GB/s controller, and installed the drivers for it on my windows, then moved the cable to the controller, haven't had a single problem anymore. I thought of this because of no option to choose between AHCI or IDE mode in my bios (i think this is because of the Striker II Extreme bios in my Striker II NSE mobo).

Bad news everybody.
I just noticed the problem returning, most importantly with NZB / News usage.
freezes are just shorter and more often now, so most applications see it as lag or just handle it ok, but it is NOT yet solved.
Becomes more frequent by the day. WIll need to swap it i guess.

I had this same problem and finally found a fix.
I am running a Lenovo X60 laptop with Windows 7 (SATA 1) with a SDSSDX-240G-G25. When I installed the drive it worked, except it would randomly "freeze" for 30 seconds or so, especially when doing a lot of reading (e.g. booting, virus scan). The drive light would be solid green the whole time as someone else described. I was upgrading from a previous SSD that didn't have this problem. I did upgrade to the latest firmware (R211) before installing.
Anyway, the DIPM seemed to be the right diagnosis, but the solution of changing the setting in the power settings didn't work for me. However, when I examined the related Registry Settings, this function was still active. So I reset the registry settings directly and the drive has been fine since.
I got the registry settings from this thread:
You may want to check the registry before modifying it just to verify that LPM/DIPM are turned on.
Hope this helps!

Same problem here. Two Extreme 480Gb. Both with R211. Both randomly hang. Resetting the PC takes a long time in POST and does not detect the drive that hung. The only way to return to operation is to power cycle the SSD. I have confirmed this by pulling the power from the hung SSD, reconnecting it and then it can be found by the PC BIOS.
Motherboard is Gigabyte GA-Z77X-UD5H. The hanging problem only started when R211 was loaded. With R201 installed it all worked nicely. AHCI power management is off ('active') and appropriate registry entries added for iastor (as per a post I found with google).
I am starting to regret the purchase of these SSDs. My Corsair F120 still plugs along day after day after day without problem.
Is it possible to downgrade the SSDs to R201?
