As I've seen from Gigabyte forum there is no chance to make stable RAID storage system using Marvell SATA3 on my GA-P55A-UD3 mobo and the only option left for now (I'm in a hurry and have to build a new PC in two days) is to attach 6GB/s drives to Intel ICH10R SATA2 controller ports with a hope I could get some advantage of RAID anyway.
Just being curious would like to ask experts is there any Add-on PCI SATA3 controller which really can achieve 4x speed boost on RAID0 configuration as Gigabyte promised at some point (what a shame!)? Are those cards rare and expensive?
How big is the advantage should I expect from using SATA2 RAID0 virtually comparing to single connection?
And one more question: there is a jumper table on top of HDD telling the interfase speed can be lowered from 6 to 3GB/s manually. Do I really need to place a jumper or SATA2 controller will slow down the drive itself?
I would really appreciate any comments. Please drop a PM as I'm not really a subscriber.
