Why does my C partition is slower than the other even though it was in the same physical drive?

[shouenga]

I partitioned my HDD into two, C and D drive. After using it for quite some time I noticed my boot time is slowing down, and so I benchmarked my C drive using Parkdale.

Here is the benchmark of the C drive using Parkdale http://i.imgur.com/EUPHBJW.jpg
Not too good isn't it?

Driven by curiosity, I also benchmarked my D drive although it was in the same physical drive as C.
Here is the benchmark of the D drive http://i.imgur.com/frqD2TV.jpg
As you can see, the difference is staggering. How did this happen and how could I fix it?
Should I move my windows installation to D instead?

Thanks in advance!

Hi there shouenga,

You could try defragging the drive.
Another thing you can do is to just test the drive and see whether there is something wrong with it: http://www.tomshardware.co.uk/forum/282651-32-best-diagnostic-testing-utility
In case there is, you will need to back up the data stored on it.

Is it the same after reinstalling Windows?

don't know if this helps, but i've noticed the same thing on my PCIe SSD (samsung xp941) - i get benchmarks closer to the advertised specs when i run the tests on "D" or "E" partitions than when on the "C" partition

i assumed it was because the C partition has less free space and/or it was reading and writing to the same partition - but fwiw, my benchmarks are 7-10% on D & E partitions

Will try, thanks!

Haven't tried it yet, but I did consider moving the OS to D: drive

That's interesting, but that would mean migrating the OS to D: won't help : (

i didn't suggest moving the OS to D - just that whatever partition the OS is on would be slower for the reasons i suggested
