Choosing the Physical Drives
The SuperTrak EX Controller card supports:
SAS physical drives
SATA 3.0-Gb/s physical drives
SATA 1.5-Gb/s physical drives
Hard Disk Drives (HDD)
Solid State Drives (SSD)
For optimal performance, install physical drives of the same model and capacity.
The table above shows the number of drives required for each RAID level.
Level Number of Drives Level Number of Drives
RAID 0 1 or more RAID 6 4 to 16*
RAID 1 2 only RAID 10 4 or more**
RAID 1E 3 or more RAID 50 6 or more
RAID 5 3 to 16* RAID 60 8 or more
* Requires SAS expansion
** Requires an even number of drives
Note
You cannot mix HDDs and SSDs in the same disk array. If you
attempt to create an array with HDDs and SSDs, the Controller will
create two separate disk arrays, each with the specified number of
logical drives.
