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.

Weighing in at a cool 500GB (465GB formatted capacity), Seagates ninth generation Barracuda drive is ideal for those of us with huge storage needs who dont have the room in our PC case for multiple disk drives.
Massive storage space... 
Price per gigabyte a little high The Final Word While two 250GB drives may be cheaper, having 500GB in a single drive is very convenient. The 7200.9 is quiet, fast and cool.

The question of compatibility overshadows the 7200.9 as we expect that storage should plug in and behave, and the idea that a hard drive may ‘disappear' at any moment is deeply concerning. The 7200.9 is fast, quiet and good value, but its new SATA2.5 feat... |

Seagate joins Maxtor and Hitachi in offering a 500 GB hard drive in this era of ever increasing storage capacity. The Barracuda 7200.9 is a 4-platter drive with 16 mb of cache and SATA 2.5 compliance. We take a sample for a spin around our lab.
The noise character of the 7200.9 was a bit of a disappointment. The mysterious whine-at-a-distance that only showed up with the drive in certain positions was highly irritating for me, although Mike did not seem to mind it so much. That said, we have... |
