When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different standard of measurement and report
a lower capacity. In addition, some of the listed capacity is used for formatti ng and other funct ions, and thus wil l not be available for data storage. Actual quantities will vary based on various factors, including file size, file
format, features and application software. Actual data rates may vary depending on operating environment and other factors. The export or re-export of hardware or software containing encryption may be regulated by

Seagate BarraCuda 120 SSD Product Manual, Rev A 19

www.seagate.com Feature Details

7. Feature Details

7.1 Flash Management

7.1.1 Error Correction Code (ECC)

Flash memory cells deteriorate with use, which might generate random bit errors in the stored data. The BarraCuda
120 SSD applies the 340 bit/2 KB LDPC (Low Density Parity Check) of ECC algorithm, which detects and corrects errors
that occur during read process, ensures data is read correctly, and protects data from corruption.

7.1.2 Wear Leveling

NAND flash devices can undergo only a limited number of program/erase cycles. Commonly, areas of the flash media
are not used evenly. If some areas are updated more frequently than others, this reduces the lifetime of the device.
Wear Leveling extends the life of the NAND Flash by evenly distributing write and erase cycles across the media.

Seagate’s advanced Wear Leveling algorithm spreads the flash usage throughout the whole flash media area.
Implementing dynamic and static Wear Leveling algorithms improves the life expectancy of the NAND flash.

7.1.3 Bad Block Management

Bad blocks do not function properly and they can contain more invalid bits. This can make stored data unstable and
bad block reliability is not guaranteed. Blocks identified and marked as bad by the manufacturer are called “Early Bad
Blocks”. Bad blocks that develop during the lifespan of the Flash are called “Later Bad Blocks”. Seagate’s bad block
management algorithm detects the factory-produced bad blocks and manages bad blocks that appear with use. This
practice prevents data from being stored in bad blocks and improves data reliability

7.1.4 TRIM

The TRIM feature improves the read/write performance and speed of SSDs. SSDs cannot overwrite existing data, so
the available space becomes smaller with each data block use. The TRIM command tells the SSD (through the
operating system) which data blocks can be removed permanently because they are no longer in use. The SSD erases
these unused data blocks.

7.1.5 SMART

SMART, stands for Self-Monitoring, Analysis, and Reporting Technology, is an open standard that allows an SSD to
automatically detect its health and report potential failures. When SMART records a failure, users can replace the drive
to prevent unexpected outage or data loss. SMART can also inform users of impending failures while there is still time
to copy data to another device.

Seagate BarraCuda 120 SSD Product Manual, Rev A 20

www.seagate.com Feature Details

7.1.6 Over Provisioning

Over Provisioning (OP) preserves an additional area beyond user capacity in a SSD, which is not visible to users and
cannot be used by them. With Over Provisioning, the performance and IOPS (Input/Output Operations per Second)
are improved by providing the controller additional space to manage P/E cycles, which enhances the reliability and
endurance as well. Moreover, the write amplification of the SSD becomes lower when the controller writes data to the
flash.

7.1.7 Firmware Upgrade

Firmware is a set of instructions on how the device communicates with the host. Firmware can be upgraded when
new features are added, compatibility issues are fixed, or read/write performance gets improved.

7.1.8 Thermal Throttling

The purpose of thermal throttling is to prevent any components in a SSD from over-heating during read and write
operations. the BarraCuda 120 SSD is designed with an on-board thermal sensor and with its accuracy, firmware can
apply different levels of throttling to achieve the purpose of protection efficiently and proactively via SMART 12
reading.

7.1.9 Low Power Management

7.1.9.1 DIPM/HIPM/DEVSLP Mode

SATA interfaces contain two low power management states for power saving: Partial and Slumber modes. For Partial
mode, the device has to resume to full operation within 10 microseconds, whereas the device will spend 10
milliseconds to become fully operational in the Slumber mode. SATA interfaces allow low power modes to be initiated
by Host (HIPM, Host Initiated Power Management) or Device (DIPM, Device Initiated Power Management). As for HIPM,
Partial or Slumber mode can be invoked directly by the software. For DIPM, the device will send requests to enter
Partial or Slumber mode.

7.2 Advanced Device Security Features

7.2.1 Secure Erase

Secure Erase is a standard ATA command and it writes all of “0xFF” to fully wipe all the data on hard drives and SSDs.
When this command is issued, the SSD controller erases its storage blocks and returns to its factory default settings

7.2.2 SSD Lifetime Management

Total Bytes Written (TBW)

TBW measures the lifespan of the SSD. This measurement represents the amount of data written to the device. To
calculate the TBW of a SSD, use the following equation:

TBW = [(NAND Endurance) x (SSD Capacity)] / [WAF]

NAND Endurance: NAND endurance refers to the P/E (Program/Erase) cycle of a NAND flash.

SSD Capacity: The SSD capacity is the specific capacity in total of a SSD.

Seagate BarraCuda 120 SSD Product Manual, Rev A 21

www.seagate.com Feature Details

WAF: Write Amplification Factor (WAF) is a numerical value representing the ratio between the amount of data that a
SSD controller needs to write and the amount of data that the host’s flash controller writes. A better WAF, which is near
1, guarantees better endurance and lower frequency of data written to flash memory.

TBW in this document is based on JEDEC 218/219 workload.

7.2.3 Media Wear Indicator

Actual life indicator reported by SMART Attribute 231 (E7h) Life Remaining by percentage, recommends User to
replace drive before reaching 0%.

7.2.4 Read Only Mode (End of Life)

When the SSD is aged by program/erase cycles, media wear-out may cause increasing numbers of bad blocks. When
the number of usable good blocks falls outside a defined usable range, the drive notifies the host through AER event
and Critical Warning to enter Read Only Mode to prevent further data corruption. When this happens, the user should
replace the SSD with another one immediately.

7.3 Adaptive Approach to Performance Tuning

7.3.1 Throughput

Based on the available space of the disk, the BarraCuda 120 SSD regulates the read/write speed and manages the
performance of throughput. When there is a lot of space, the firmware continuously performs read/write actions.
There is no need yet to implement garbage collection to allocate and release memory to accelerate the read/write
processing and improve performance. When there is less available space, the SSD slows down the read/write
processing and implements garbage collection to release memory.

7.3.2 Predict and Fetch

When the Host tries to read data from the SSD, the SSD performs only one read action after receiving one command.
However, the BarraCuda 120 SSD applies Predict and Fetch to improve the read speed. When the host issues
sequential read commands to the SSD, the SSD automatically expects that the following is also read commands.
Therefore, before receiving the next command, flash has already prepared the data. This accelerates data processing
time, and the host needs to wait less time to receive data.

7.3.3 SLC Caching

The BarraCuda 120 SSD firmware design adopts dynamic caching to deliver better performance, endurance and user
experience.
