1. Product Description
1.1
Introduction
Apacer’s Serial ATA Flash Drive (SAFD) is a non-volatile SATA solid-state drive (SSD) that serves as the
ideal boot drive or mass storage device. Compliant with SATA 3.0 Gbps 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.
SAFD 25M4 drive is designed with a powerful controller, offering capacities of up to 64 gigabytes and
providing full support for the SATA 3.0 Gbps high-speed interface standard. It can operate at sustained
access rates up to 165 megabytes per second, while power consumption remains at minimal level. Regarding
data integrity and memory efficiency, the controller unit of the device handles wear leveling, ECC, bad block
management and power management in urgent situations.
In addition, SAFD 25M4 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 25M4 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
SAFD25M4 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.
