Since I felt that my Windows 10 system wasn’t performing at its max, I decided to check the speed of the 3 drives in my machine with HD Tune. What I found out was that the system drive’s speed is around 2-5 mb/s. which of course is unacceptable.
So I decided to clone that system on to another drive, and booted from that instead.
- Result with the new drive: Same - very slow!
- Result with the old drive: Now the readings look good, 140-150 mb/s. Booting from the old drive afterwards made it again show as very slow, whereas the new drive would show normal reading speed (>100 mb/s).
I’m not changing any cables and not changing the SATA port they’re connected to, just changing the drive/partition being booted from in a menu created using EasyBCD.
What on earth can be causing this, and what can be done to resolve it?
PS: Given the nature of the problem, I’m assuming there’s no need to post a bunch of details about hard drive models etc. Correct me if I’m wrong.
