1. General Description
Apacer’s SDM5A (SATA Disk Module 5A) is our next generation disk-on-module (DOM) series that offers
elevated speed boost and higher error correction capabilities. Built with SATA 6.0 Gb/s interface, SDM5A
delivers higher performance in data transfer than its previous SDM selections, reaching up to 65 MB/s in
read and 105 MB/s in write.
With its SATA interface compliance and compact size, this high-speed disk module defines an ideal
balance of performance, capacities, reliability and cost. SDM5A comes in moderate capacities that are
suitable to boot industrial applications and light operating systems for specific operations, while with some
extra memory space for data storage. The architectural nature of SATA disk module provides higher
resistance to external environmental influences and better flexibility for motherboard space.
Regarding data reliability, SDM5A is built in with powerful ECC engine that can correct up to 40 bits per
1KB data. In addition, the controller unit of this DOM device supports wear-leveling, SMART and power
failure management for data integrity. With its trustable reliability, performance and cost effectiveness,
Apacer’s SDM5A is definitely the ideal storage or cache solution for embedded and industrial computers,
servers and thin clients.
