Hello! Assuming that CPanel/WHM server is mainly dedicated for email purpose for accounts with 10-20 mailboxes each (also all active accounts are using Web pages) and these customers are using mail every day for their business. Average mailbox size 6GB. Are there possible to use SATA disks for servers? What can be limits (disk size, customer/mailbox count, average mailbox size) if mailboxes is used with IMAP when using SATA disks? Server will be virtualized on Cloud hosting provider (Citrix XenServer) Thanks!

  Mail operations run through small files in 2k-4k size. Sata disks have low file write read speeds, which can cause i / o wait problems on the system. It is preferable to use an ssd disk that has higher iops values in small files.

  For SATA, you need to be careful about using a consumer drive if you are building a RAID array. Some power saving features and in the case of Western Digital, some of their SATA drives have a "deep recovery" process when an error is detected. These can cause a SATA RAID member to be dropped or marked as failed if it is unresponsive beyond the timeout period. When a SATA RAID5 volume with huge drives drops a member, it is not uncommon for the rebuild to take several hours. During this time, performance will be abysmal.
