due to a failing drive, I am looking to replace my Series 3 (OLED) 250GB stock hard drive. I wasn't looking to do a huge upgrade since this is a DVR in a basement rec room and not used a lot. It was recommended that I get the Western Digital 500GB WD5000AVDS drive. I also have a S3 OLED image to put on it vis WinMFS so can do the whole procedure on my own. While it is highly rated for DVR use, this also appears to be a "green" drive, correct? If so, does this mean I will ultimately have to disable its "intellipark" feature? Or should I maybe go with another 500GB model? If so, which one?
