2 Years ago I decided to buy one 2 TB Hard drive. My choise was WD because I had prblems with two drives from Seagate. So I bought one 2TB WD HDD (model WD20EARX-00PASSB0). After one year I have trouble when the OS write to drive.
It takes almost 1 hour until a 1GB is written to the drive. The transfer rate falls below 4MBytes /s. The SMART feature doesn’t report any trouble. When the transfer rate drops it seems that the drive seek the secors where to write.(Moves the heads back and forth)
At first I thought that can be a driver issue but is not be ,because I have another two drives (500 GB each) on the sane SATA Host and I don’t have this issue. I tried on different SATA ports (6 and 3 Gb).
The SATA interface settings in the BIOS is set to AHCI and NCQ is enabled.
My configuration is:
Mainboard: Intel® Desktop Board DX79SI
CPU: Intel Core i7 3930K
RAM: 32GB Geil Veloce (Quad Channel)
HDD: 1 x Intel 240 GB SSD (520 Series)
2 x Seagate ST3500320
1 x WD20EARX-00PASSB0
OS: Windows 7 SP1 64 bit
If you have some idea what else can I do, tell me please. If I find a solutin I will wrie it down. Thank You
