s ata - disk module ap - sdmxxxx1pa x s - e 3 ? 20 10 apacer technology i nc. rev . 1. 1 1 . p roduct description 1.1 introduction apacers sata disk module ( s dm ) is a solid - state disk (ssd) drive that contains a controller, embedded firmware, and f lash m edia along with a male connector. using nand flash memory devices, t he sdm drive interfaces with the host allowing data to be seamlessly transferred between the host and the f lash devices . the sdm drive is designed with a single - chip controller , offer ing capacit ies of up to eight gigabytes and providing full support for the sata high - speed interface standard. it can operate at sustained access rates of up to thirty five megabytes per second, which is much faster than any other competitor in the market . in addition to buffer management through dynamical allocation, the sdm adopt s the static wear - leveling scheme to allow uniform use of all storage blocks , ensur ing that the lifetime of a flash media can be significantly increased and the disk performance is optimized as well. the sdm provides the s.m.a.r.t. feature complies with the sata rev. 2. 6 , ata/atapi - 7 specifications and uses the standard smart command b0 h to read data from the drive. this feature protects the user from unscheduled downtime by monitoring and storing critical drive performance. 1. 2 function al block diagram the sdm drive include s a single - chi p sata c ontroll er and the f lash m edia , as well as the sata standard interface. the c ontroller 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. f igure 1 - 1 apacer sdm block diagram
