Hello,
I ran a full system test at http://www.pcpitstop.com/
The results were fine except for BOTH my hard drives. Their uncached were very low, 18 and 15 mb/s respectively for Samsung SV3063H and Western Digital WD600BB-00CXA0 (These are the names in my device manager).
Compared to other systems with similar processor and clock speed, they were at 47% and 39% speed respectively.

I'm not quite sure what they mean by this. Their definition:
"Cached and uncached speed is measured in megabytes per second (MB/s). When a percentage is shown for cached and uncached speed, it compares the performance of the drive with those of systems in our database with the same processor and clock speed. (Our database currently has 2198 similar systems.) A rating of 200% means a disk is twice the performance of similar systems, 50% means it's half the performance. Cached disk speed generally measures the efficiency of the system's processor and memory system, not the performance of the hard disk. Uncached speed is most affected by the physical hard disk and the disk interface. "

Is something wrong with my drives that coudl slow down my system? If so what is it and how can the problem be resolved?
