Product Description
The GLS88AR128G3 / 256G3 / 512G3 / 001T3 /002T3 Commercial Temperature NVMe M.2
ArmourDrive™ PX Series (referred to as “M.2
ArmourDrive” in this datasheet) are high-performance,high-reliability solid state drives. They combine 128,
256 or 512 GBytes, or 1 or 2 TBytes of NAND flash
memory with an advanced NVMe PCIe controller on aprinted circuit board (PCB). NVMe is a highly scalable
protocol optimized for efficient data transport overPCIe for storage on NAND flash.

The NVMe PCIe SSD controller with built-in advanced
NAND management firmware communicates with thehost through the standard PCIe interface. It does not
require 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’s advanced NAND management
technology improves endurance, enhances data
security and helps prevent data corruption during
unexpected power failure events. This innovativetechnology combines robust NAND controller
hardware error correction capabilities with advanced
wear-leveling algorithms and bad block management
to improve data reliability and significantly extend thelife of the product.

M.2 ArmourDrive is ideal for applications that require
removable form factor and more reliable data storage.
NVMe M.2 solid state storage technology is used inindustrial and cloud computing, datacenters, highperformance enterprise storage and networking
systems, endpoint and thin clients, gaming machinesand broadcasting equipment. These removable solidstate drives (SSDs) provide low latency and fast
sequential and random read/write speeds.

GENERAL DESCRIPTION

Each M.2 ArmourDrive module integrates an NVMe PCIe SSD controller with up to four NAND flash multi-chippackages. Refer to Figure 2-1 for the M.2 ArmourDrive block diagram.

1.1

1.1.5 Power Interrupt Data Protection

Optimized M.2 ArmourDrive

The MCU translates PCIe / NVMe commands into
data and control signals required for flash media
operation.

Power Interrupt Data Protection is a mechanism toprevent data corruption during unexpected power
failure events. Enhanced data integrity is supported by
the controller’s advanced firmware during abnormal
power loss. The controller proactively optimizes theamount and stay time of the “in-flight” data residing inthe cache. To ensure there is no data loss risk causedby power cycling, the controller sends anacknowledgement to the host only when the incoming
data is fully committed to the NAND flash.

1.1.2 Internal Direct Memory Access (DMA)

1.1.6 Error Correction Code (ECC)

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.

The ECC technology uses advanced LDPC algorithms
to detect and correct errors, ensuring data integrityand extending the SSD lifespan.

The heart of M.2 ArmourDrive is the NVMe PCIe SSD
controller, which translates standard PCIe signals intoflash media data and control signals. The following
components contribute to M.2 ArmourDrive’s
operation.
1.1.1 Microcontroller Unit (MCU)

1.1.7 Multi-tasking Interface
The multi-tasking interface enables concurrent Read,
Program and Erase operations to multiple NAND flash
media.

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

1.2

M.2 ArmourDrive’s controller uses advanced wearleveling 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.
1.1.4 Embedded Flash File System
The embedded flash file system is an integral part of
M.2 ArmourDrive. It contains MCU firmware that
performs the following tasks:

1.3

1. Translates host side signals into flash media
writes and reads
2. Provides flash media wear leveling to spreadthe flash writes across all memory address
space to increase the longevity of flash media
3. Keeps track of data file structures

Advanced NAND Management

Advanced Data Security

Advanced data security measures include end-to-end
data path protection, data sanitization and Secure
Erase support. Secure Erase is an effective method toquickly wipe all data from a PCIe-based SSD using theNVMe protocol (Format NVM).
