I installed Win7 64bit on bootcamp yesterday.

My ssd is 'Owc aura pro 6G 480'.

It seems to be bad.. for random 4K read/write.

Is this normal?

IRST and AHCI driver is installed already..

I allowed 50GB space for bootcamp partition.

thats your problem, sandforce doesnt perform well, needs more space and currently windows on your machine should be gulping half of that.

its simple you need more space if you want better performance

unallocated space is a good idea as well, when anandtech gets back online, check the review of the intel sc3700 ssd, specially in the consistency section

Bootcamp partition( 50GB of toal SSD 480GB) has 70% free space.
Is not enough?:(

Total my ssd space 480GB.

I allocated 50GB bootcamp with bootcamp utilty.

So my mac has two partitions.

mac os X partition has 360GB free of 430GB,

bootcamp has 38GB free of 50GB

you should enlarge the bootcamp partition that should solve the low 4k results, test it under osx as well

um..I understood that performance is affected by free space,

but in my case, bootcamp has enough free space (38GB of 50GB).

I think 'low 4K' problem is unrelated with bootcamp total space..

Is it wrong?

Is there any person has problem like me??

I'm confused with 38GB free (out of 50) why should he enlarge his bootcamp partition with so much free at the moment. :confused:

I said to enlarge because in any case if the OP install something there like office, thats 1.5gb out of the park if install a game that 10gb out.

um..I understood that performance is affected by free space,

but in my case, bootcamp has enough free space (38GB of 50GB).

And to answer maflynn and you, try to test it under OSX as well as I said before, and enable trim on OSX

if its the same result its not performing as it should

Another thing to try is to wipe it all out and install a new

And no, low 4k depends on several factors, and the size of the bootcamp partition may be one of the,
