Intel 330 120GB lower performance when filled with data ?

post #1 of 2
Thread Starter 
Hi,

I have an Intel 330 120GB SSD.
Before Windows installation when it was blank I got in Crystal Disk Mark Seq test for example 470MB/s read and 160MB/s write.
Now after I installed Windows, drivers, application I get 440MB/s read and 130MB/s write.
I have an AsRock Z77 Extreme 4 motherboard and the SSD is connected on Intel controller with latest Intel Rapid Storage drivers installed.
Also I saw on reviews that they got even higher scores, why do I get lower scores ?

P.S.

Also I have 2 hdd's WD 1TB FAEX ... both new, one is giving me 106MB/s read and the other 130MB/s ... why is that difference ?

As far as I'm aware all SSDs will become slower when they're filled. As for the difference in speed between the 2 HDDs, I think that the speed they advertise is an average so not all of them are going to run a t the same speed.
