I have a Q9450 CPU, 8GB RAM, 6 HDDs and Windows 7 x64.
A few days ago I've mirrored one of the storage HDDs, a 2TB Samsung, using Windows 7 Storage Manager, using an identical 2TB Samsung.
Everything seems OK, the matrix is healthy, etc.
But, it feels like the system isn't as snappy as before, and the only thing that the PC is doing on that mirrored array is that uTorrent uploads at max 100KB/s.
Could Windows 7 software RAID1 slow down PC's response?
