1. Product Description
1.1
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 multi-level cell (MLC) NAND flash memory
devices, the SAFD drive interfaces with the host allowing data to be seamlessly transferred between the host
and the flash devices.
The SAFD 254 drive is designed with a single-chip controller, offering capacities of up to 256 gigabytes and
providing full support for the SATA II high-speed interface standard. It can operate at sustained access rates of
up to 100 megabytes per second, which is much faster than any other solid-state or traditional SATA drive
currently available on the market.
In addition to buffer management through dynamical allocation, the SAFD 254 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. The SAFD 254 provides
the S.M.A.R.T. feature that follows the SATA Rev. 2.5, 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
The SAFD 254 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.
