I'm looking for a hardware RAID5 capable PCI-E SATA controller to replace my Highpoint RocketRAID 2320. The current spec of the system is as follows: Asus P6T7 WS Supercomputer Intel i7 950 @ 3.07 ghz 6gb of RAM 350gb Raptor – boot drive 1.5tb Seagate- network drive 8 x Seagate 1.5tb drives in a RAID 5 array via a Highpoint RocketRAID 2320 Radeon 5870 Pioneer 5090 Plasma display @ 1920 x 1080 Corsair HX450W running RAID array and a 1000w supply feeding the rest It needs to be Win 7 64 friendly, have full hardware RAID, take at least 8 drives and be quick enough for HD movie files to be accessed across the network. The RocketRAID 2320, while claiming to be hardware RAID, is far too processor hungry - in Win 7 just running the card has CPU usage sitting at 15 - 20%, in Vista it is up around 35%. It also seems to be throttling the north bridge on my P6T7 WS Supercomputer (something I barely thought possible) and killing the performance of my newly installed Radeon 5870. Any advice would be much appreciated - price isn't too much of an issue but I'd be reluctant to go above £800.
