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 -- Best Regards MfG Robert Schetterer
