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 drive

transfers data between the host and the storage devices at a radical high speed, making it a great partner for

embedded systems and servers.

SAFD 18P drive is designed with a single-chip controller, offering capacities of up to 128 gigabytes and

providing full support for the SATA 3.0 Gbps high-speed interface standard. It can operate at sustained

access rates of up to higher than 260 megabytes per second, providing an ideal solution for industrial

applications.

In addition, SAFD 18P adopts the Apacer-specific 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. SAFD 18P provides the S.M.A.R.T. feature that follows the SATA Rev. 2.6,

ATA/ATAPI 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.

SAFD 18P drive includes a single-chip SATA 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.
