Industrial Grade SATA M.2 2242 ArmourDrive™ EX
Series modules (referred to as “M.2 ArmourDrive” inthis factsheet) are high-endurance, high-reliability
solid state drives. They include 20, 40, 80, 160 or 320
GBytes of NAND flash memory with an advanced
Serial ATA (SATA) controller on a printed circuit board(PCB).

The NAND flash controller with built-in advanced
NAND management firmware communicates with thehost through the standard SATA protocol. It does notrequire any additional or proprietary software such as
the Flash File System (FFS) and Memory Technology
Driver (MTD). The firmware effectively optimizes theuse of NAND flash memory’s program/erase (P/E)
cycles and minimizes write amplification.
M.2 ArmourDrive is pre-programmed with a 10-Byte
unique serial ID and has the option of programming
an additional 10-Byte serial ID for even greatersystem security.

M.2 ArmourDrive is ideal for applications that require
removable form factor and more reliable data storage.
Serial ATA (SATA) M.2 solid state storage technology
is widely used in industrial computers, test andmeasurement
instrumentation,
multi-functional
printers, medical equipment, security and surveillancesystems, network servers and digital signage. These
removable solid state drives (SSDs) surpass
traditional hard disk drives (HDDs) in their small size,
security, reliability, ruggedness and low power
consumption.

GENERAL DESCRIPTION

Each M.2 ArmourDrive module integrates a SATA SSD controller with NAND flash multi-chip packages. Refer toFigure 2-1 for the M.2 ArmourDrive block diagram.

1.1

1.1.5

Optimized M.2 ArmourDrive

The ECC technology uses advanced algorithms todetect and correct errors, ensuring data integrity andextending the SSD lifespan.

The heart of M.2 ArmourDrive is the SATA SSDcontroller, which translates standard SATA signals
into flash media data and control signals. The
following components contribute to M.2 ArmourDrive’soperation.
1.1.1

1.1.6

1.2

Internal Direct Memory Access (DMA)

Power Management Unit (PMU)

The PMU controls the power consumption of M.2ArmourDrive. The PMU dramatically reduces thepower consumption of M.2 ArmourDrive by putting thepart of the circuitry that is not in operation into sleep
mode.

1.3

Advanced NAND Management

M.2 ArmourDrive’s SATA controller uses advanced
wear-leveling algorithms to substantially increase thelongevity of NAND flash media. Wear caused by data
writes is evenly distributed in all or select blocks in thedevice that prevents “hot spots” in locations that areprogrammed and erased extensively. This effective
wear-leveling technique results in optimized device
endurance, enhanced data retention and higher
reliability required by long-life applications.

The Flash File System handles inadvertent powerinterrupts and has auto-recovery capability to ensure
M.2 ArmourDrive firmware integrity. For regular powermanagement,
thehostmustsend
anIDLE_IMMEDIATE command and wait for command
ready before powering down M.2 ArmourDrive.
1.1.4

EnduroSLC™ Technology

EnduroSLC™ is a proprietary 3D NAND management
technology developed by Greenliant for high reliability
applications requiring ultra-high endurance andsuperior data retention. Using 1-bit-per-cell (SLC)
NAND configuration, EnduroSLC enabled SSDs are
ideal for write-intensive applications used in extreme
temperature, high stress environments. EnduroSLC
enabled solid state drives offer a high reliability flash
storage solution with ultra-high write endurance thatexceeds capabilities of legacy, planar SLC NAND
based products.

M.2 ArmourDrive uses internal DMA allowing instantdata transfer from/to buffer to/from flash media. This
implementation eliminates microcontroller overhead
associated with the traditional, firmware-based
approach, thereby increasing the data transfer rate.
1.1.3

Multi-tasking Interface

The multi-tasking interface enables fast, sequential
write performance by allowing concurrent Read,
Program and Erase operations to multiple flash media.

Microcontroller Unit (MCU)

The MCU translates SATA commands into data andcontrol signals required for flash media operation.
1.1.2

Error Checking and Correction (ECC)

Embedded Flash File System

The embedded flash file system is an integral part ofM.2 ArmourDrive. It is integrated in the controller’s
firmware that performs the following tasks:
1. Manages and optimizes the data access of flash
media
2. Provides flash media wear leveling to spread theflash writes across all memory address space toincrease the longevity of flash media
3. Keeps track of data file structures
