Hard Drives 
The MD3200i and MD3220i support SAS hot-pluggable HDDs (hard-disk drives) and SSD (solid-state 
drives).  MD3200i allows for both 3.5-inch and 2.5-inch form factor drives, and the MD3220i allows for 
2.5-inch form factor drives.  Note that 2.5” HDD in the MD3200i requires a unique drive carrier that 
houses a 2.5” HDD and fits into a 3.5” HDD slot.  Any combination of SAS rotational speeds and SSD 
drives can be mixed within an MD3200i or MD3220i enclosure.
