Hi, I'm trying to find out which controller card people here recommend that can
drive 8 SATA hard drives and that would work with my Asus M2N-SLI Deluxe
motherboard, which has following expansion slots:
2 x PCI Express x16 slot at x16, x8 speed (PCIe)
The main requirements I have are:

After checking some more sources, it seems that if I used the AOC-SAT2-MV8 with
this motherboard, I would need to run it on the standard PCI slot. Here is the
full listing of the motherboard's expansion slots:
2 x PCI Express x16 slot at x16, x8 speed
2 x PCI Express x1
3 x PCI 2.2

Are you taking snapshots periodically? If so, you're
using a build old
enough to restart resilver/scrub whenever a snapshot
is taken.
Actually yes, I take snapshots once an hour of various things. I'll try
disabling them for the time being and see how far along it gets.
Thanks!

I use the AOC-SAT2-MV8 in a ordinary PCI slot. The PCI slot maxes at 150MB/sec
or so. That is the fastest you will get. That card works very good with
Solaris/OpenSolaris. Detects automatically, etc. Ive heard though that it does
not work with hot swapping discs - avoid this.

It's great to hear that you've had good experiences with the card. It's a great
