1. Product Description
1.1 Introduction
Apacer SFD18SH-M half-slim MO-297 SSD (Solid State Drive) delivers multiple technological advantages
of flash memory storage. With SATA 6.0 Gbps interface, SFD18SH-M offers exceptional data transfer
performance. Form factor wise, this model is fully compliant with JEDEC MO-297 standard, which is
designed with standard interface consisting of SATA 7-pin signal segment and 15-pin power segment, while
in compact size. This module provides low power consumption compared to traditional hard drive and hot-
swapping when removing/ replacing/ upgrading flash disks. Its capacity could provide a wide range up to
256 GB. Moreover, it can reach up to 430 MB/s read as well as 160 MB/s write high performance.

*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.
