I just built my PC last night and my HDD is only getting a 5.9 in WEI while everything else gets above 7. Is this normal? The HDD is a Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s. Also, when I was extracting a large zip file, it was only transferring data at about 19.2 MB/s. Seemed a little low for the HDD I have. This is my first build so I may be missing something obvious. Thanks.
