Summary: I replaced my Seagate 2TB hard drive when the temperature began shooting up to 140 degree F. This new WD drive operates at a reliable 87 degrees F. I bought it as a kit expecting a disk, manual, and any needed parts.
Summary: Just the past month I had 3 WD hdd died on me, all while My computer was on. They just disappears, and when I restarts, my computer can't get past bios or can't start windows. Had to remove them.
Summary: I use one of these as a storage drive in my desktop. For my purposes this drive performs great, as it is used exclusively for storage and not for gaming. The drive represents great value but the trade-off: it's really slow. If you are not installing games off of this drive you will be okay.
Summary: This hard drive is quiet and quick. Two of my favorite things for hard drives. I did have trouble installing it though. I have older hardware (2008) with Win 7 64bit installed. Had to install special software and format the drive to 2TB and 1TB because of a 2TB limit with older hardware.
Summary: I don't know exactly how much power it saves, but I can tell you the spindles do in fact spin down. I use it as a media drive in my desktop computer. When it is reading or writing the drive stays active and performs well enough to not be noticeable.
Summary: Purchased for my Windows Home Server. Be sure to put a jumper on pins 7-8 for WHS to recognize, I installed without the jumper and even though everything looked ok, windows did not see the entire drive and started giving me disk full warnings when copying files back to the drive.
