22 MACH2 2.5-Inch Serial ATA Solid State Drive
WRITE DMA QUEUED CCh This command is mandatory for devices that implement the TCQ
feature set. The command is similar to the Write DMA (CAh)
command. The device may perform a release or may execute the
data transfer without performing a release if the data is ready to
transfer. If the device performs a release, the host should reselect
the device using the SERVICE command. Once the data transfer
has begun, the device shall not perform a release until the entire
data transfer is complete.
WRITE DMA QUEUED EXT 38h This command is mandatory for devices that implement the TCQ
and 48-bit Address feature sets. The command is similar to Write
DMA Extended (35h). The device may perform a release or may
execute the data transfer without performing a release if the data
is ready to transfer. If the device performs a release, the host
should reselect the device using the SERVICE command. Once
the data transfer has begun, the device shall not perform a
release until the entire data transfer is complete.
WRITE DMA QUEUED FUA EXT 3Eh This command is mandatory for devices that implement the TCQ
and 48-bit Address feature sets. The command is similar to the
Write DMA Extended (35h) command. The device may perform a
release or may execute the data transfer without performing a
release if the data is ready to transfer. If the device performs a
release, the host should reselect the device using the SERVICE
command. The device does not perform a release once the data
transfer has begun and has been completed.
WRITE MULTIPLE C5h This command is similar to the Write Sector(s) - 30h command.
Interrupts are not presented on each sector, but on the transfer of
a block which contains the number of sectors defined by the Set
Multiple Mode - C6h command.
WRITE MULTIPLE EXT 39h This command is mandatory for devices that implement the 48-bit
Address feature set. The command will write the number of
logical sectors specified in the Count field. The command is
similar to Write Sector(s) (30h). Interrupts are not presented on
each sector, but on the transfer of blocks that contain the number
of sectors defined by LBA mode.
WRITE MULTIPLE FUA EXT CEh This command is mandatory for devices that implement the 48-bit
Address feature set. The command has the same functionality of
Write Multiple Ext (39h), except that regardless of whether write
caching is enabled, the user data is written to the media before
the ending status of the command is reported.
WRITE SECTOR(S) 30h This command will write from 1 to 256 sectors as specified in the
Sector Count Register. A sector count of 0 (zero) will request 256
sectors. The transfer begins at the sector specified in the Sector
Number Register.
WRITE SECTOR(S) EXT 34h This command is mandatory for devices that implement the 48-bit
Address feature set. The command will write 1 to 65,536 logical
sectors as specified in the Sector Count Register. A sector count
value of 0 will request 65,536 logical sectors.
