Introduction

Apacer’s mSATA M4-M is a solid-state disk (SSD) drive in mini PCIe form factor that contains a controller,

embedded firmware, and flash media along with a male connector. mSATA M4-M leverages the advantages

of standard SATA SSDs in terms of wide compatibilities and reliable performance. Though built with MLC, this

SSD can work in highly demanding environment as it can withstand ambient temperature from -40°C to +85°C

(for certain capacities only).

mSATA M4-M drive is designed with a single-chip controller, offering capacities of up to 128 gigabytes and is

compliant with the SATA

high

Ⅱ

-speed interface standard. Complying with JEDEC MO-300 standard, this

mSATA SSD is the widely adopted embedded storage with compact size and exceptional performance.

In addition, mSATA M4-M adopts the Apacer-specific global wear-leveling scheme to allow uniform use of all

storage blocks, ensuring that the lifespan of a flash media can be significantly increased and the disk

performance is optimized as well. mSATA M4-M provides the S.M.A.R.T. feature that follows the SATA Rev.

2.6, ATA/ATAPI-7 specifications and uses the standard SMART command B0h to read data from the drive.

This feature protects the user from unscheduled downtime by monitoring and storing critical drive performance.
