In reply to CameronS. I know your comment is 2 yrs old, but what else would you recommend for extreme IO Raid controllers then? I use to use Adaptec in the oooold days around 2001 and they were expensive and mostly crap, I managed to break at least 2 I can think of, but its been 12 yrs and I am willing to try again, if you say they dont break :) How many times in how many 24-7 days did the Areca cards crash?

I know this is an old test, but how can this RAID controller fire off more than 2GB/s ?

It’s labeled as a PCI-e 8x, meaning 8 channels of 250MB/s each way, max 2 GB/s (bit less as we divide by 1024 but still).

Did they use the full 16x when they had to or is this testnumber of 3GB/s skewed by the cache on the RAID card?

Lets say you fired up 64GB RAM, used 56GB in a RAMdisk for extreme IO purposes, then took a backup of those 56GB to the RAID, could it maintain 2+ GB/s then?

Would be interesting to test out next time.

These may be great cards for enthusiast gamer workstations. We’ve had poor reliability in our IO intensive enterprise application. They crash, taking the OS with them. We’re swapping them back out, in favor of slower but reliable enterprise class controllers.
