First my apologies if this questions has been asked. I've googled… and googled some more and can't seem to find what I'm looking for.
Anyone know of a software or web based calculator that will let you plug in a RAID configuration (example below) and output expected R/W speeds, hopefully in MBs
Number of disk, size, spin, type , Raid type
EX. (8, 73Gb, 15k, SAS, Raid 1/0)
Or
EX. (6, 146Gb, 10k, FC, Raid 5)
I found severely that calculate available space. Some that give some speed info, but they can't be realistic because they don’t take spin or type in the consideration.

I don't know of a calcualtor that can tell you that, in part because there are so many other factors besides just the disk and connection type factors. The RAID controllers make a huge difference, as can the firmware on those controllers, the type of data, as does the ability of the motherboard to push data. Your best bet is benchmarking on your own. I can't even think of a way to write a calculator do do that sort of thing. Also I believe that probably for most operations the network will bottleneck before the RAID.
