Hard drives or SSDs

A hard disk drive (HDD), is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating
disks coated with magnetic material. A solid-state drive (SSD), is a solid-state storage device that uses integrated circuit assemblies as
memory to store data persistently. SSDs have no moving components. SSDs are typically more resistant to physical shock, run silently,
have lower access time, and less latency.
Your system supports up to two 2.5-inch SAS or SATA or PCIe SSDs or SAS or SATA hard drives and four 1.8-inch SATA SSDs. The hard
drives or SSDs are supplied in special hot-swappable drive carriers that fit in the drive bays and these drives connect to the system board
through the hard drive backplane board.
NOTE: Mixing of SSD or SAS or SATA hard drives is not supported.
