* For all present ThinkStation, the total capacity in any RAID schemes can't exceed 2.2 TB (due to BIOS limitation). ** ThinkStation S20 does not contain onboard SAS controller, some models contain an additional SAS card (See SEV6-1 or SEV7-2). *** ThinkStation D20 supports two RAID schemes simultaneously from 5 disk bays. **** The spare disk is used to recover faulty hard disk from the RAID and cannot be used as a normal hard disk.
