Features of the Single M.2 Adapter:
6 Gbps SATA host interface (connects to the PCH)
Supports one 6 Gbps SATA M.2 drive**
Supports 3 different physical sizes of M.2 drives: 42mm (2242), 60mm (2260) and 80mm (2280)*
Drive firmware update using Lenovo firmware tools
Management via I2C interface
VPD reporting of adapter inventory
* 2242, 2260 and 2280 are the industry terms for the M.2 drive dimensions. For example, 2280
corresponds to a drive that is 22mm wide and 80mm long.
** When using configure-to-order (CTO), you can also select zero drives and add drives as a field upgrade.

* These drive options do not have power-loss capacitors, which means they do not have protection against
a potential loss of data when a write operation is underway just as a power outage occurs. As a result,
these drives are not recommended for general purpose storage functions.
