Generally, there is no performance advantage, unless the disk is a significant bottleneck for your workload. If you're receiving mail, generally the bottleneck is content inspection. If you're sending mail at under 100 msgs/sec, or virus-scanning outbound mail, a modern server with a RAID controller with a BBU, will be plenty fast. If you to get well north of ~300 msgs/sec, then perhaps you need a faster disk, or more machines, whichever is more cost effective. For a sufficiently expensive SSD, another server may be a better option, though cost of cooling, power and data-center space also comes into the equation. -- Viktor.
