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 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.
1.2
Functional Block Diagram
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.

*Display of total bytes varies from file systems.
**Cylinders, heads or sectors are not applicable for these capacities. Only LBA addressing applies.
***Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
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.
