    Z77 RAID5 Performance is HORRIBLE!


      I built Z77-based system. I have five 2 TB WD disks connected to the Z77 controllers. I have them set up in a RAID 5 array. I'm running Win 64-bit.


      When I run disk speed tests I can reads around 300 MB/sec. That's awesome!


      However, when there is continuous disk reading or writing, the system gets super sluggish.


      I've got Media Center running. If I'm recording two HD shows and playing another one back, I can't do much else on the system.


      If I try and rar or unrar some large file during this recording the system is crazy sluggish.


      What can I do to fix this? I'm really disappointed.
