1. General Description
Apacer’s ATA-Flash Drive (AFD) is a high-performance, solid state drive (SSD) designed to replace a
conventional IDE hard disk drive. AFD supports standard ATA/IDE protocol and can be plugged into a
standard IDE connector commonly found in desktop or portable PCs. It is more rugged, reliable and
power-efficient compared to the mechanical hard drive and is designed for use in rugged laptops, military
devices, thin clients, Point of Sale (POS) terminals, telecom, medical instruments, surveillance systems
and industrials PCs. AFD also offers users selectable Master/Slave operation through an external jumper
setting. Apacer AFD Series is the best instant replacement for high-maintenance HDD where reliability is
a major concern.
AFD includes a built-in microcontroller and file management firmware that communicates through with the
ATA standard interfaces. AFD is designed to work at 5 Volts, support the standard ATA/IDE protocol up to
PIO Mode-4, Multiword DMA Mode-2, and Ultra DMA Mode-6 interfaces, and use a standard ATA driver
that fits to most of the mainstream operating systems. Featuring technologies as Advanced Wear-leveling
algorithms, S.M.A.R.T, Flash Block Management, Power Failure Management, and ATA Secure Erase,
the AFD device assures users of security in storage applications.
