So a few years ago I bought a new laptop for school(contains Llano A6 3400m APU, 6GB 1333mhz, etc.) and then decided to throw an Intel 330 180GB SSD into it. Installed Win 7 into it, and found that the drive would freeze up/hang for 60sec+ regardless of what I was doing(Hard drive light was lit up whole time, system was unresponsive other then mouse cursor movement). Did a lot of reading, tried updating the AMD AHCI drivers, but did not fix it. Read that setting SATA mode to IDE (my laptops case is "Compatibility Mode") can fix the issues, or changing power management settings in the Intel SSD Toolbox if you have an Intel platform.
So, with my time off from school due to arm injury from mountain biking during spring break, I decided to upgrade my laptop to Windows 8.1, but for the first install i left SATA option to AHCI in the laptop BIOS, but the issue was still there with a clean WIn 8.1 install. Did it again with it in Compatibility Mode (IDE) and have not had freezing since. Pretty wierd issue really, sounds like I am not the only person with the issue with the Intel 330 drives. I guess this is one of the reasons they released the 335s, and didnt help anyone on the intel forums about the 330 issue, they just went silent till the 335s released.
So anyways I got the Update 1 this morning too, and so far its a nice improvement to what I already really liked in 8.1. Love that even Metro Apps now have EXIT and minimize buttons like normal window apps. Also now boot to desktop is on by default which is really nice. Even in IDE mode, this drive is still much faster then the original platter drive. Also got the new office and setup my laptop for pure school work and program development for my Cpt Science classes.
Kind of a redundant post, but oh well.
