I have 2TB WD Black, 2013 version. At first, I used it for operating system, and found that when running a game, HoN, the hard drive almost always ran at 100% and caused lags sometimes; however, I had another PC that had WD Blue and lower specs, it ran fine. The drive seems to be slower than WD Blue as well. So I bought an SSD and moved OS to it. Even for photo viewing only, it is still slow. I ran a benchmark based on Userbenchmark.com and it said that my drive’s speed is only around 70% of what it should be on average. In addition, there is no app really running on it at the time I tested it. I ran benchmark 3 times, resulted similarly. I did defragment and check using WD Data life guard, there is no error. Do you think “write zero” might help? Or should I just send it to be fixed?
My PC specs:
Core i5 4590
RAM 4x4GB Kington 1600MHz
SSD: Intel 730 240GB
Mainboard: Gigabyte Gaming 3 Z97X
Running on Windows 10. I updated both Windows and drivers to the newest. Thanks in advance
