1. Product Description
1.1 Introduction
Apacer’s mSATA A1 is a well-balanced solid-state disk (SSD) drive with compact form factor (JEDEC MO-300)
and great performance. Designed in SATA 6.0 Gbps interface, the mSATA SSD is able to deliver exceptional
read/write speed, making it the ideal companion for heavy-loading embedded or server operations with space
constraints for host computing systems. 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.

1. Display of total bytes varies from file systems. 2. Cylinders, heads or sectors are not applicable for these capacities. Only LBA
addressing applies.3. 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.
