1. Product Description
1.1
Introduction
Apacer’s SATA Disk Module (SDM) 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 SDM drive
interfaces with the host allowing data to be seamlessly transferred between the host and the flash devices.
The SDM drive is designed with a single-chip controller, offering capacities of up to eight gigabytes and
providing full support for the SATA
Ⅱ
high-speed interface standard. It can operate at sustained access rates
of up to thirty five megabytes per second, which is much faster than any other competitor in the market.
In addition to buffer management through dynamical allocation, the SDM 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 SDM provides the S.M.A.R.T.
feature complies with 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.

Functional Block Diagram
The SDM 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.
