1. Product Description
1.1 Introduction
Apacer’s SFD18A is a well-balanced solid-state disk (SSD) drive with standard form factor and great
performance. Designed in SATA 6.0 Gbps interface, the SSD is able to deliver exceptional read/write speed,
making it the ideal companion for heavy-loading industrial or server operations. In regard of reliability, the drive
comes with various implementations including powerful hardware ECC engine, power saving modes, wear
leveling, flash block management, S.M.A.R.T., TRIM, and power failure management.

*Display of total bytes varies from file systems.
**Cylinders, heads or sectors are not applicable for these capacities. Only LBA addressing applies.
LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of
the device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small
portion of the capacity is reserved for device maintenance usages.
