1. Product Description
1.1
Introduction
Apacer’s SAFD18S4 is a solid-state disk (SSD) drive that contains a controller, embedded firmware, and flash
media along with a male connector. Compliant with SATA II standard, the drive conforms to most mainstream
host system platforms with SATA-compliant interfaces, making it the primary storage solution for replacing
traditional hard disk drive.
SAFD18S4 drive is designed with a powerful single-chip controller, offering capacities of up to 64 gigabytes
and providing full support for the SATA high-speed interface standard. It can operate at sustained access
rates of up to 160 megabytes per second while operating at relatively low power consumption, this SATA SSD
is an ideal replacement for conventional hard disk drive in industrial computing applications.
In addition, SAFD18S4 adopts the Apacer-specific global 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. SAFD18S4 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.
1.2
Functional Block Diagram
SAFD18S4 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.

*Display of total bytes varies from file systems.
**Cylinders, heads or sectors are not applicable for these capacities. Only LBA addressing applies.
LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of
the device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small
portion of the capacity is reserved for device maintenance usages.
