Anyone else have a disk performance they would like to share.


I've got a single WDBlack for a system drive, and 5.9 is my score as well. Something must wrong? confused Is write-caching enabled on your drive?

Yes. I'm running one 1Tb WD now and it's still showing 5.9 so it must be pretty easy to hit that mark.
The two drives were benching around 99Mb/sec and this WD by itself is around 70.

5.9 is the is the limitation that 99% of drives will run into if they are running a standard SATA drive. You can slightly higher if running an optimized hardware RAID 0 setup and the drives and controller have a good amount of cache (my setup got 6.1).

To get higher than that, you will need to step up to SSD over SATA or SCSI, iSCSI, or SAS.

Sorry guys, but 5.9 is it unless you make a significant increase in spending.

That is VERY high UTR. What card do you have?

I have a GTX295, flagship of the nVidia line, and that only gets a 7.3...
