I have 8 hard drives in my PC, assigned as storage.
- Three of them are attached to the mainboard.
- Four of them are attached to a controller [ SiL 3114 ]
- One of them attached to an another controller [ SiL 3114 #2 ]
These hard drives are the very same, Samsung Spinpoint models. Same RPM, same size.
I wanted to make a raid from ALL of them, using Windows Server 2008R2. However, the performance is just outright terrible. It's hardly faster than one hard drive.
I checked the SMART values, they are all correct.
Any ideas, what might be the problem?
Ps.: There is a spare 320gb WD disk in the machine, and a 320gb WD as system drive.
