With some hard disk controllers it is normal for it to show up as a SCSI disk - particularly if the disk controller is running in AHCI mode, which is preferrable since it allows features such as NCQ. One thing you may want to check is: locate the drive itself under "Disk Drives" in device manager and go into the properties. Select the "Policies" tab and view what is set. For better performance you will want it set to "Better Performance" with both of the boxes checked. Though if you lose power you may run into minor file corruption issues - I personally have not had issues with this. If you disable those check-boxes performance can decrease significantly.
