Hm. If it's a system with only 1 PCI bus, there are still a few things to consider here. If it's plain old 33mhz, 32 bit PCI your 100MB/s(ish) usable bandwidth is actually total bandwidth. That's 50MB/s in and 50MB/s out, if you are copying disk to disk... I am about to update my home server for exactly the issue of saturating my PCI bus... It's even worse for me, as I'm mirroring, so, that works out to closer to 33MB/s read, 33MB/s write + 33 MB/s write to the mirror. All in all, it blows. I'm looking into one of the new gigabyte NVIDIA based systems with the 750aSLI chipsets. I'm *hoping* the Solaris nv_sata drivers will work with the new chipset (or that we are on the way to updating them...). My other box that's using the Nforce 570 works like a champ, and I'm hoping to recapture that magic. (I actually wanted to buy some more 570 based MB's but cannot get 'em in Australia any more... :) Cheers!
