1. Product Overview
1.1 Introduction of InnoAGETM InnoAGE 2.5” SATA SSD 3TI7
The InnoAGETM SSD comes with a Microsoft Azure Sphere inside, and is further integrated with
Innodisk’s customized firmware, software, and hardware technology. This new solution enables
multifunctional management: smart data analysis and updates, data security, and remote control
through the cloud, while benefitting from the power of the Azure Sphere to guarantee secured
communications between the SSD and the cloud.
The InnoAGE™ SSD delivers an easy-to-use interface with its customized cloud management
platform. In technical terms, the Innodisk-developed firmware receives commands from the Azure
Sphere via a second connection to Azure. Therefore, it is able to execute SSD debugging messages
as well as monitor read/write behavior patterns to increase the storage device’s lifespan. Most
importantly, system operators can quickly revert to the default settings from the cloud-based
dashboard in the case of a device or system crash.
In other words, the InnoAGE™ SSD is designed for both in-band and out-of-band network
management, providing full recovery even when the operating system has crashed or is severely
impaired to the extent that in-band management would be of little help.
CAUTION TRIM must be enabled.
TRIM enables SSD’s controller to skip invalid data instead of moving. It can free up significant amount of
resources, extends the lifespan of SSD by reducing erase, and write cycles on the SSD. Innodisk’s handling of
garbage collection along with TRIM command improves write performance on SSDs.

3. Theory of Operation
3.1 Overview
Figure 2 shows the operation of Innodisk InnoAGETM 2.5” SATA SSD 3TI7 from the system level,
including the major hardware blocks.
Figure 2: Innodisk InnoAGETM 2.5” SATA SSD 3TI7 Block Diagram
Innodisk InnoAGETM 2.5” SATA SSD 3TI7 integrates a SATA III controller and NAND flash memories.
Communication with the host occurs through the host interface, using the standard ATA protocol.
Communication with the flash device(s) occurs through the flash interface.
3.2 SATA III Controller
Innodisk InnoAGETM 2.5”SATA SSD 3TI7 is designed with a SATA III 6.0Gbps (Gen. 3) controller.
The Serial ATA physical, link and transport layers are compliant with Serial ATA Gen 1, Gen 2 and
Gen 3 specification (Gen 3 supports 1.5Gbps/3.0Gbps/6.0Gbps data rate). The controller has 4
channels for flash interface.
3.3 MCU
Innodisk InnoAGETM 2.5”SATA SSD 3TI7 is with out-of-band signaling, which is integrated MCU
to separate connection channel. This independent communication channel is assuring constant
access, InnoAGETM 2.5”SATA SSD 3TI7 is always ready for user to remotely control such as

InnoAGETM 2.5” SATA SSD 3TI7
18 Rev 1.0 TPS, Apr., 2020
recovery, backup, and secure erase without depending on the reset of the system being functional.
InnoAGETM 2.5”SATA SSD 3TI7 is embedded Azure Sphere to implement out-of-band function.
Azure Sphere is Microsoft-designed MCU intended for use in IOT devices. Functioning as a system
itself, the Azure Sphere runs the Azure Sphere OS, which allows the device to operate
independently of the host device’s OS. To ensure that device remains fully protected against
external threats such as unauthorized access attempts, Microsoft has created a powerful security
suite to ensure device integrity ad to protect the hardware form malicious actors. The security

3.4 Error Detection and Correction
Innodisk InnoAGE 2.5” SATA SSD 3TI7 is designed with hardware LDPC ECC engine with
hard-decision and soft-decision decoding. Low-density parity-check (LDPC) codes have excellent
error correcting performance close to the Shannon limit when decoded with the belief-propagation
(BP) algorithm using soft-decision information.

3.5 Wear-Leveling
Flash memory can be erased within a limited number of times. This number is called the erase
cycle limit or write endurance limit and is defined by the flash array vendor. The erase cycle
limit applies to each individual erase block in the flash device.
Innodisk InnoAGE InnoAGE 2.5” SATA SSD 3TI7 uses a static wear-leveling algorithm to ensure
that consecutive writes of a specific sector are not written physically to the same page/block in the
flash. This spreads flash media usage evenly across all pages, thereby extending flash lifetime.
3.6 Bad Blocks Management
Bad Blocks are blocks that contain one or more invalid bits whose reliability are not guaranteed.
The Bad Blocks may be presented while the SSD is shipped, or may develop during the life time of
the SSD. When the Bad Blocks is detected, it will be flagged, and not be used anymore. The SSD
implement Bad Blocks management, Bad Blocks replacement, Error Correct Code to avoid data
error occurred. The functions will be enabled automatically to transfer data from Bad Blocks to
spare blocks, and correct error bit.
3.7 iData Guard
Innodisk’s iData Guard is a comprehensive data protection mechanism that functions before and
after a sudden power outage to SSD. Low-power detection terminates data writing before an
abnormal power-off, while table-remapping after power-on deletes corrupt data and maintains
data integrity. Innodisk’s iData Guard provides effective power cycling management, preventing
data stored in flash from degrading with use.
3.8 Garbage Collection/TRIM
Garbage collection and TRIM technology is used to maintain data consistency and perform
continual data cleansing on SSDs. It runs as a background process, freeing up valuable controller
resources while sorting good data into available blocks, and deleting bad blocks. It also
significantly reduces write operations to the drive, thereby increasing the SSD’s speed and
lifespan.
3.9 Trim
The Trim command is designed to enable the operating system to notify the SSD which pages no
longer contain valid data due to erases either by the user or operating system itself. During a
delete operation, the OS will mark the sectors as free for new data and send a Trim command to
the SSD to mark them as not containing valid data. After that the SSD knows not to preserve the
contents of the block when writing a page, resulting in less write amplification with fewer writes to

the flash, higher write speed, and increased drive life.
3.10 iPower Guard
iPower Guard technology is a set of preventive measures that protect the SSD in an unstable
power supply environment. This comprehensive package comprises safeguards for startup and
shutdown to maintain device performance and ensure data integrity.
3.11 Die RAID
Die RAID is a controller function which leveraged user capacity to back up the data in NAND flash.
Die RAID supported can ensure the user data in the NAND Flash more consistent in certain
scenario. Innodisk M.2 (S80) 3TE7 series is default enable the Die RAID function for the industrial
application.
3.12 Hardware-based 256-bit AES
Innodisk InnoAGE 2.5” SATA SSD 3TI7 is designed with 256-bit AES engine, which is built-in the
controller. When controller receives the data package from host, AES engine encrypts the data
package and save the encrypted data into NAND flash. Thus, unauthorized personal has no access
to decrypt the data in NAND flash. Hardware-encryption also means that the process is fully OS
independent, as it does not require compliance with any system or software.
3.12.1 InnoAGE SSD with AES Flow Chart
In order to complete the physical security layer of protection, encryption needs to be paired with an
ATA user password by ATA security command. After setting the authorized key by ATA security
command, every time when you power on the system with SSD encrypted, you will be requested
for a password to access the SSD. If the password is correct, the SSD will run well; if not, then you
will not be able to access the SSD then.
