1. Product Description
1.1
Apacer’s Serial ATA Flash Drive (SAFD25M2) is a solid-state disk (SSD) drive that contains a controller,
embedded firmware, and flash media along with a male connector. Using NAND flash memory devices, the
SAFD25M2 drive interfaces with the host allowing data to be seamlessly transferred between the host and the
flash devices.
The SAFD25M2 drive is designed with a single-chip controller, offering capacities of up to 32 gigabytes and
providing full support for the SATA Ⅱ high-speed interface standard. It can operate at sustained access rates
of up to 100 megabytes per second, which is much faster than any other solid-state or traditional SATA drive
currently available on the market.
In addition to buffer management through dynamical allocation, the SAFD25M2 adopts the static wear-leveling
scheme to allow uniform use of all storage blocks, ensuring that the lifetime of a flash media can be
significantly increased and the disk performance is optimized as well. The SAFD25M2 provides the S.M.A.R.T.
feature complies to the SATA Rev.2.6, ATA/ATAPI-7 specifications and uses the standard SMART command
B0h to read data from the drive. This feature protects the user from unscheduled downtime by monitoring and
storing critical drive performance.
1.2
The SAFD25M2 drive includes a single-chip SATA Ⅱ Controller and the flash media, as well as the SATA
standard interface. The controller integrates the flash management unit with the controller itself to support
multi-channel, multi-bank flash arrays. Figure 1-1 shows the functional block diagram.
