Product Description
The GLS89SQ128G3 / 256G3 / 512G3 / 001T3 /002T3 Commercial Temperature SATA 2.5”
ArmourDrive™ PX Series (referred to as 2.5”
ArmourDrive” in this factsheet) 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 DRAM and an advanced Serial ATA(SATA) controller in a standard 2.5-inch form factor
housing.

The SATA SSD controller with built-in advanced
NAND management firmware communicates with thehost through the standard SATA protocol. 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.
2.5” 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.

2.5” ArmourDrive is ideal for applications that require
hot-swappable and reliable data storage. 2.5” SATA
solid state storage technology is widely used inservers, laptops, network-attached storage, industrial
computers,navigation
systems,
testandmeasurement instrumentation, multi-function printers,
security and surveillance equipment, digital signage
and networking systems. These removable solid statedrives (SSDs) surpass traditional hard disk drives(HDDs) in their security, reliability, ruggedness andlow power consumption.

GENERAL DESCRIPTION

Each 2.5” ArmourDrive integrates a SATA SSD controller with NAND flash multi-chip packages and DRAM in astandard 2.5-inch form factor housing. Refer to Figure 2-1 for the 2.5” ArmourDrive block diagram.

1.1

Optimized 2.5” ArmourDrive

1.1.5

Power Interrupt Data Protection is a mechanism tohelp prevent 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 an
acknowledgement to the host only when the incoming
data is fully committed to the NAND flash.

The heart of 2.5” ArmourDrive is the SATA SSD
controller, which translates standard SATA signals
into flash media data and control signals. The
following components contribute to 2.5” ArmourDrive’soperation.
1.1.1Microcontroller Unit (MCU)

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

Internal Direct Memory Access (DMA)

1.1.6

2.5” 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

1.1.7

Power Management Unit (PMU)

Multi-tasking Interface

The multi-tasking interface enables concurrent Read,
Program and Erase operations to multiple NAND flashmedia.

1.2

Advanced NAND Management2.5” 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 ensure2.5” ArmourDrive firmware integrity. For regular powermanagement,
thehostmust
send
anIDLE_IMMEDIATE command and wait for command
ready before powering down 2.5” ArmourDrive.
Embedded Flash File System

The embedded flash file system is an integral part of2.5” ArmourDrive. It is integrated in the controller’s
firmware that performs the following tasks:

1.3

Advanced Data Security

Advanced data security measures include end-to-end
data path protection, data sanitization (Secure Erase)and cryptographic erase (Crypto Erase) support.
Secure Erase is an effective method to quickly wipe alldata from a SATA-based SSD using the SATA
protocol. Cryptographic erase resets the cryptographic
key of an OPAL-activated SSD making all encrypteduser data useless. 2.5” ArmourDrive’s controller
supports industry standard AES-256 encryption toprotect sensitive user data.

1. Manages and optimizes the data access of flash
media
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

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

The PMU controls the power consumption of 2.5”
ArmourDrive. The PMU dramatically reduces thepower consumption of 2.5” ArmourDrive by putting thepart of the circuitry that is not in operation into sleep
mode.
