1. Product Description
1.1 Introduction
Apacer SM220-300B is a well-balanced solid-state disk (SSD) drive with compact form factor (mSATA mini)
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. For data efficiency, the internal controlling unit of the mSATA 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 Functional Block Diagram
SM220-300B drive includes a single-chip SATA Controller and the flash media, as well as the SATA standard
interface. The controller integrates the flash management unit with the controller itself to support multi-channel,
multi-bank flash arrays. Figure 1-1 shows the functional block diagram.

1.3 Capacity Specifications
Capacity specifications of SM220-300B product family are available as shown in Table 1-1. It lists the specific
capacity, the default numbers of logical cylinders and heads, and the number of logical sectors per track for
each product line.

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