The answer to that will depend on a mountain of things, not least:

1) How many *concurrent* users?
2) What IMAP server?
3) What configuration of SATA drives?  A single 1 TB drive will be
slower to read than a pair of 1 TB in a RAID0, which will be slower
than 4 half TB drives in a RAID10.  Good quality (ie expensive) SATA
RAID will be faster than cheap hardware RAID, and software RAID may be
faster than cheap hardware RAID.
4) What else is the host doing?
