Thin Provisioning
The device supports thin provisioning and the READ CAPACITY 16 (9Eh) command, but
the level of thin provisioning support varies by product model. Thin provisioning re-
turns a default data pattern from a READ command to a logical block even when that
block is not mapped to a physical block by a previous WRITE command.
To determine whether thin provisioning is supported and which of its features are im-
plemented, a READ CAPACITY 16 (9Eh) command must be issued to the drive. The
LBPME (logical block provisioning management enabled) bit settings indicate whether
the logical unit implements LBPM (logical block provisioning management). The
LBPME and LBPRZ (logical block provisioning read zeros) bit settings are shown in the
table immediately below.
