Hi,

I need your help here. I got this Micronet 4-bay eSATA external enclousre recently. The drive came with a pci-express x1 raid controller card that uses the Silicon image sil3132 chipset.

I have the 4 drives setup in a raid-5 configuration. The setup went smooth, but what troubles me is the write speed. It is very very slow, barely exceeded 3.1MB/sec. I thought the problem was in the BIOS or the driver, so I updated my system with the latest BIOS and drivers for the controller card, but no changes on speed at all.

Is RAID-5 always this slow? What kind of speed I should expect from a raid-5 setup using the sil3132 cards?

I am thinking of buying a better and faster raid controller card. It has too support raid-5 and have e-sata ports. Do you have any recommendations?


My system:

Motherboard: asus p5w-dh deluxe
CPU: intel quad core Q6600
OS: windows vista 64bit
RAM: 6GB RAM




Thanks!
