For hard drive storage, |prod| supports high-performance |SSD| and |NVMe|
|
|
drives as well as rotational disks.

To increase system performance, you can use a |SSD| or a |NVMe| drive on |prod|
|
|
hosts in place of any rotational drive. |SSD| provides faster read-write access
|
|
than mechanical drives. |NVMe| supports the full performance potential of |SSD|
|
|
by providing a faster communications bus compared to the |SATA| or |SAS|
|
|
technology used with standard |SSDs|.
|
|
|
|
On storage hosts, |SSD| or |NVMe| drives are required for journals or Ceph
|
|
caching.
|
|
|
|
.. xrefbook For more information about these features, see |stor-doc|: :ref:`Storage on Storage Hosts <storage-hosts-storage-on-storage-hosts>`.
|
|
|
|
For |NVMe| drives, a host with an |NVMe|-ready BIOS and |NVMe| connectors or
|
|
adapters is required.
|
|
|
|
To use an |NVMe| drive as a root drive, you must enable |UEFI| support in the
|
|
host BIOS. In addition, when installing the host, you must perform extra steps
|
|
to assign the drive as the boot device.
