I have recently purchased an HP a1350n AMD 64 x2 with a 250 GB SATA II hard drive. I am using this machine for my main desktop and am looking for the best performance while using multiple "recourse and data intense" apps and large file read/write operations.
The motherboard has two slots for SATA cables a PCI e and 3 PCI slots. The second available SATA slot is for an additional drive for additional storage, there is not onboard RAID controller
I am currently using a multiple monitor setup that uses a gForce PCI e card and only have 1 of the 3 PCI slots available. I have done some research on PCI cards that provide RAID solutions but have not been able to clearly determine if the read/write speeds would be better running RAID 0 through the PCI bus or just using a single HD connected to the SATA port on the motherboard. The current HD is large enough for my needs and I would be willing to sacrifice the PCI e graphics card if it meant a "significant" speed gain by using a PCI e RAID controller card.
Would a SATA II RAID 0 PCI or PCI e card solution (up to about $200 US) provide a significant performance increase?
