NTFS compression on SSD

[LOST TALE]

Should I turn on file compression on an SSD. Could it be so fast that my CPU bottlenecks read speed during game load times?

 

I read this but posting for comments:

MIght as well try it. I have found games to have no noticable load time difference, but will use about 10-40% less disk space.

 

CPUs can compress and de compress data very fast now, normally faster than the ssd can read or write the data.

 

Random IO is a bit worse due to how NTFS does compression, so 64k(i think) of data needs to be read for any random read.

how bad is the effect on random IO as it seems to be very important for performance. Have you tested and compared on crystal disk bench?

Also, I used compression on one of my drives but now I wonder how better random 4k would be without it.

Crystal disk mark isn't a great test here as its either uncompressable data, or all zeros, so not a good test.

 

Why not test it your self? You already have the hardware and software to test.

and no because it's easier to look it up or ask
