Summary: I used to have a 5400rpm, 80 GB hard drive in my Vista laptop. After a year and a half of new software, and gunking up the hard drive, I had only 10 GB of space left, which made my laptop pretty slow. I popped this 7200rpm, 320 GB hard drive in, and reinstalled from the factory image. WHAT A HUGE DIFFERENCE! No problems at all swapping it out. It boots up in half the time it did when new with the smaller hard drive.
Summary: I upgraded my Dell XPS 1645 HDD with ease. I did a clean install of Windows 7 Pro and everything went well, not a single problem. This thing is fast and very quiet, did not think a 7200 RPM would be this quiet. I have always trusted Western Digital with my data, from external to internal hard drives. Highly recommended!
Summary: OMG it does actually run quicker! And a whopping 500GB MORE CAPACITY! Well I never really believe it was going to be so easy to find a replacement but this took the biscuit! SO EASY to replace! I honestly felt so gutted when my HD failed and I knew it had cos it was leading up to the event. I was honestly thinking I might have to face a new purchase at a heavy cost. Amazing and thank you for packaging the disk so safely..!
Summary: Purchased as a replacement drive for a Macbook Pro. Turned out that a cable had failed in the mac so using this as a drive in an external HD video recorder. Great drive, quiet operation which runs cool and fast enough to capture files. Great drive, good capacity and price.
