Pretty much all of the deployments that I have seen, a single mirror set is

I would be looking at the disk queue using perfmon and making sure that
there isn't a backlog of requests. As long as there isn't then there
shouldn't be a major hassle with disk performance on a Citrix server.

It's definitely a case of YMMV though. I have seen some instances with
applications that build a a database locally, copy data from another
database server into it's database, use it and then wipe it at logoff. When
you have 40 users on a server, it can blow the disks away. The same would go
if you were running a VMWare server and had the disks locally for 10 servers
sitting on top, the IO/sec requirements could be quite high.

Either way, take a look at what you are actually doing, and if required get
some smaller disks then less large ones, this will give you more IO/sec.
