Compare HDD: 8 2 TB hard drives

Since our last hard drive comparative published in August 2010 and updated in January, several manufacturers have developed their disk array. This is the case with Hitachi Deskstar 5K3000 for the arrival and 7K3000, but Seagate has changed from generation to its 5900 rpm drives (eg Barracuda LP) which are now findable under the name Green.

7 models but 8 discs
At Hitachi Deskstar 7K3000's (HDS723020BLA642) and Hitachi Deskstar 5K3000 (HDS5C3020ALA632). Both drives run at 7200 and 5700 rpm and 64 and feature 32 MB cache. They share a SATA 6G interface and 3 plates with a density of 667 each. 

Samsung has only one drive of this capacity, the EcoGreen F4 (H204UI). 3G using a SATA interface, which is not problematic because hard drives her away from saturating, it has 32 ​​MB of cache and has 3 667 GB platters. 

At Seagate Barracuda XT (ST32000641AS ) and Barracuda Green (ST2000DL003). This time both drives share the SATA 6G interface and a 64MB cache Their respective rotation speeds of 7200 and 5900 rpm, and if the XT embarks 4500 GB platters, Green's team of 3 667 GB platters . 

For Western Digital, we test three discs. The WD Caviar Black one hand (WD2002FAEX) uses the SATA 6G interface and has 64MB cache. These trays 4 500GB running at 7200 rpm. For the WD Caviar Green WD20EARS, we have two versions: WD20EARS-00MVWB0 and WD20EARS-00J2GB0, which are respectively equipped with 3 shelves 667 GB and 4500 GB platters. 

Although the second version is scarce, it n is not impossible to find so we have to integrate into the comparison as Western has not bothered to create two separate commercial references. These disks share a 3G SATA interface and a 64MB cache Recently, a new reference to Caviar Green appeared, WD20EARX. According to the Western site it differs only due to its SATA 6G interface, and it is hoped that this appointment will ensure the presence of 3 plates.

The test
We have taken the test protocol inaugurated in the 2011 comparative SSD hard drive for this test. Only differences we use H2BENCH for sequential speeds, so as to obtain the flow depending on the position of the read head on the disc, and practice tests are relieved to be limited to the launch of 3D Studio Max, loading a level of Crysis and Photoshop CS installation 5. All tests are performed on P67, SATA 6G. However, the discs are far from saturating this interface, and switching to 3G have almost no impact on the performance of the manager 6G models.

Come naturally grafted specific tests to hard drives, namely the measurement of temperature records, and their noise. They are identified using a Cirrus Optimus CR152A Class 2 meter It measures sound levels as low as 21 dBA, which makes the room used to go down. This is the second use of this high-end sound level meter after our comparative cooler.
