1. Product Description
1.1
Introduction
Apacer’s Serial ATA Flash Drive (SAFD) is a standard 2.5-inch solid-state drive (SSD) designed for
embedded applications in demanding environments. SAFD 25P-M drive is designed with a single-chip
controller and provides full support for the SATA II high-speed interface standard. The device supports
capacities up to 512GB and is able to operate at sustained access rates at an ideal speed up to 260 MB/s,
which is much faster than any other traditional SATA-based hard disk drive currently available on the market.
Though built with MLC, this SSD can work in highly demanding environment as it can withstand ambient
temperature from -40° to +85° (for certain capacities).

In addition, SAFD 25P-M 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-M 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-M 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.

*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.
