Hard disk drives are today's fastest permanent storage media and have a large capacity. For this two reasons they are the most used storage medium in computers and servers. When buying a new hard disk, there are three important things to consider: - The connection of the disk to the computer or other device you will be using it with has a big influence on the speed with which data can be read from/written to the disk. Make sure the connection of the disk you buy is compatible with your computer! - The rotational speed is also important for the speed with which data can be read from/written to the disk and determines the time it takes to find a file on the disk. - Last but not least, the storage capacity of the disk, i.e. the amount of data that can be stored on the disk.

Western Digital's 640GB Caviar Green is the most environmentally-friendly drive in this month's Labs. The 500GB and 1TB Caviar Green drives consume a meagre 4W, but the 640GB model uses only 3W of electricity. Performance was less impressive, though. T...
Bottom line The greenest drive on test, although performance is disappointing...

Hard disk drives are quickly and constantly growing up in capacities. Of course, every one of us would be glad to be presented a large HDD as a gift, but when it comes to purchasing one for your own money, there are other factors to consider. Some user...
Bottom line Now that we’ve come to the end of today’s test session, we should name the fastest 500GB hard disk drive available today. There are actually two winners: the Seagate Barracuda 7200.12 and the Western Digital Caviar Black. The former has somewhat higher...

Western Digital has been on our watch list since they sent us their (then) flagship 500 GB drive with seeks that we could hardly hear. This is the WD first drive sample that weve seen since, and its unusual: Their PR says its Green, low power, and v...
Bottom line Its the quietest desktop drive weve ever tested. Its the most efficient drive weve ever tested. And it comes in capacities up to 1 TB. What more do you want? As far as SPCR is concerned, this could be the perfect drive — at least until flash media...
