Not What I Was Expecting
01/16/2011
This review is from: Rosewill RC-211 Silicon Image 2 port SATA II PCI Express Host Controller Card RAID 0/1/0+1/5 JBOD
Pros:
Has jumper to bypass onboard BIOS, very small size, seems sturdy, supports SATA II, supports LBA48, comes with latest firmware and drivers. Allows bootable install of RAIDed Windows XP once everything is figured out.
It will get the job done, although I will use it for DVD and backup drive in IDE/SATA mode via jumper setting.
Cons:
Confusing instructions, system will not boot if motherboard and card RAID are both turned on and drives are attached to card - at least one must be set to IDE/SATA mode (I was hoping to use both for RAIDing).
Poor overall I/O performance compared to SB700. Somewhat of a CPU hog at times. GUI is OK, but need to read all instructions on SI website, 2 or 3 times. Took a lot of trail and error to figure everything out.
Overall Review:
Stats from testing using PC Wizard on new Barracuda 250GB drives that were initialized, repartitioned and reformatted (Quick NTFS) before each test was run under Windows XP Pro:
