There has been a debate among a few colleagues of mine centered around what can be gained by having larger cache on RAID controllers. While all kinds of 'tests' can be performed that show a larger cache can help with this or that specific type of IO on  a test basis, the other half of the question is that for a very large enterprise - hundreds of users  - with a wide mix of processing going  on - a great deal of word processing/Excel of relatively small files, some line of business app with some kind of SQL database, e-mail, the occasional large file transfer - the argument is that in general the users will not see any difference.

I would appreciate feedback on this especially if it's  backed up my real world stats as opposed to 'simulation' stats produced by  testing software or simply theories/logical analysis of why one or another alternative should make a difference that does not have some actual real world numbers to back it up.
