1. General Descriptions
1.1 Introduction
Apacer’s SM210-25 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.
For data efficiency, the internal controlling unit of the SSD is engineered with DRAM for enhanced
random performance. 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.
1.2 Capacity
Capacity specifications of SM210-25 are available as shown in Table 1-1. It lists the specific capacity
and the default numbers of heads, sectors and cylinders for each product line.

*Display of total bytes varies from file systems, which means not all of the bytes can be used for storage.
**Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
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.
