post #1 of 9
Thread Starter 
Check out the Drive speed reductions going from near empty drive to almost full!

EMPTY:



FULL:

Yup, that'll happen. The drive needs empty blocks to "cache", I think.

Sandforce drives have a "feature" lol that causes write speed throttling if there are too many writes in a short period of time. That "feature" is called duraclass and is supposed to protect the longevity of the drive. Running 5x1000mb packages of Crystaldiskmark will cause write throttling faster than anything so I recommend creating a system image with the Windows 7 tool, secure erase the drive and re-image. If you have to use CDM, at least select 1 pass and a smaller file size. Change from random data to all 1's or zeros.

Next time you get up from your PC log out and leave it at that screen for an hour or two.

It's a simple matter of garbage collection.
I'll run a benchmark that nearly reaches advertised speeds with 20 GB free when I get home if that would make you feel better.

Hard drive, not solid state.
HDD slow up as you write data farther near the center which does not have the same velocity as the outer edge.
