1. Product Description
1.1 Introduction
Apacer’s Serial ATA Flash Drive (SAFD) 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 SAFD drive
interfaces with the host allowing data to be seamlessly transferred between the host and the flash devices.
SAFD 25P drive is designed with a single-chip controller, offering capacities of up to 256 gigabytes and
providing full support for the SATA II high-speed interface standard. It can operate at sustained access rates
higher than 200 megabytes per second, which is much faster than any other traditional SATA-based hard disk
drive currently available on the market.
In addition to buffer management through dynamical allocation, SAFD 25P adopts the global wear-leveling
scheme to allow uniform use of all storage blocks, ensuring that the lifespan of a flash media can be
significantly increased and the disk performance is optimized as well. SAFD 25P provides the S.M.A.R.T.
feature that follows 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 Functional Block Diagram
SAFD 25P 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.
