How does this sound?

Sweet!

Performance will always be limited by the slowest bottleneck. As you've found when creating a RAM disk, you can really see that a single non-RAID desktop system has pretty slow disk I/O compared to the ReadyNAS. I suspect that you may be hitting some sort of bottleneck on your Mac Mini. Maybe you need to buy another Utra to test performance! :wink:

I've written an article on some of the factors that come into play when testing performance: http://home.bott.ca/webserver/?p=363

Does adding one more disk do anything with the performance? Does it help or hurt it?

More disks = more speed 8) - viewtopic.php?f=21&t=54618#p310625

Ok, I now have 4 disks installed, which I added one at a time, waited for the volume expansion to complete, and then tested. Bonnie (add-on disk diag) reported 1 disk - 59.7 MB/s 2 disks - 110 MB/s 3 disks - 219 MB/s 4 disks - 319 MB/s So the disk throughput definitely goes up as you add more disks. However, the iometer speed did not change on my Windows 7 machine. No matter how many drives were installed, I still see 55-60 MB/s of read performance, and 80-83 MB/s of write performance. So there is more investigation needed on that.
