and SAS may not be faster always, it deeply depends on motherboard
,bios versions, drivers, date of release, storage modell etc

SAS could be faster but it must not everytime and everywhere

IMAP and specially mailserver storages may have other needs
as other servertypes, so it depends on general parameters
which you like to goal, parameters i.e may your budget
number of mailboxes, size of mailboxes, number of parallel users,
mailbox type, cluster filesystem ,loadbalancing setup
soft/hardware raid/hardware, use drbd and/or san/nas specialized
hardware etc

so i found very interesting info in this thread , but at the end
it is not very helpfull to decide what to use in real world mailsetups
this is always a local decision by local circumstances

there are no general easy answers for this theme, that fit simply all
and as in real life , dont think what fits best to you , ist the best
for others
