1. Product Description
1.1
Apacer’s SAFD18S4 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 SAFD drive interfaces with the
host allowing data to be seamlessly transferred between the host and the flash devices.
SAFD18S4 drive is designed with a single-chip controller, offering capacities of up to 64 gigabytes and
providing full support for the SATAⅡ 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, 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-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
SAFD18S4 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.
