Introduction
This product manual describes the functional, mechanical, and interface
specifications for the WD Blue™ 3D NAND SATA SSD (solid-state drive).
General Description
The WD Blue 3D NAND SATA SSD delivers high performance and reliability with low
power consumption in large capacities. It is based on state-of-the-art BiCS3 64L
TLC (triple level cell) flash technology and incorporates the proven tiered caching
architecture designed to improve responsiveness for corporate and consumer

Introduction
Advanced Flash Management
Defect and Error Management
The WD Blue 3D NAND SATA SSD contains an enhanced defect and error
management system that is similar to systems found in hard disk drives (HDDs). If
necessary, the device will rewrite data from a defective block to a good block. This
action is completely transparent to the host and does not consume any user data
space.
The WD Blue 3D NAND SATA SSD soft error rate
specification. In the rare case when a read error occurs, the drive uses Error
Detection Code (EDC) and Error Correction Code (ECC) algorithms to recover the
data. These defect and error management systems give it unparalleled reliability.
The WD Blue 3D NAND SATA SSD also includes a robust error handling mechanism
which can recover errors that other traditional error correction mechanisms cannot.
This mechanism can leverage a hardware XOR core to calculate the extra parity
the-fly with minimal impact in performance.
Wear Leveling
Wear leveling is an intrinsic part of the erase pooling functionality. NAND-based
SSDs use dynamic and static wear leveling and automatic block management to
ensure an even distribution of write/erase cycles throughout the entire device.
These processes guarantee high data reliability and maximize
Wear leveling is done between all TLC blocks and separately between all SLC
blocks.

Bad Block Management
Bad blocks are occasionally created during the life cycle of a flash component.
These bad blocks must be marked and replaced dynamically in order to prevent
read/write failures. When a bad block is detected, the embedded Bad Block
Mapping algorithm removes the block from future use.
Background Garbage Collection
The flash management firmware will perform internal housekeeping activities, such
consolidating and
data in the TLC array or SLC array. These activities are performed in the background
and are transparent to the host, thus improving performance while providing a
seamless user experience.
flushing the SLC blocks to the TLC storage or reorganizing the
Tiered Caching
The WD Blue 3D NAND SATA SSD uses a tiered caching structure to improve write
performance and endurance.
Introduction
Modern operating systems typically access the storage device using small access
blocks; the majority of these being 4KB. These access blocks are incongruent with
the physical block size (less than 1MB) of the newer generation of
technology, and writing directly to the TLC array is also slower than writing to SLC
blocks. To overcome these hurdles, the WD Blue 3D NAND SATA SSD employs three
storage layers:
▪ Volatile cache — DDR DRAM cache
▪ Tiered Caching structure — A non-volatile
▪ Mass storage — TLC NAND
The tiered caching structure is a pool of X1 blocks which are used as write cache to
accumulate and consolidate all writes at high speed. It works in the background,
then flushes them into the larger X3 storage blocks and uses optimized write
transaction sizes to maximize endurance.
All host data is written to X1 blocks to achieve the highest performance. Three X1
blocks are copied sequentially into one X3 block during the
when exceeding their threshold.

Low-Density Parity-Check (LDPC)
An enhancement introduced with the WD Blue 3D NAND SATA SSD is the lowdensity parity-check (LDPC) error correction code (ECC) technology. LDPC
significantly improves reliability over the previous generation of BCH code,
supports progressive levels of error correction, and runs on-the-fly using a
dedicated hardware core to minimize latency and impact on overall drive
performance. Consequently, it uses less power than deeper dynamic read retries.
Advanced Power Management
The WD Blue 3D NAND SATA SSD includes an advanced power management
system that supports Device Initiated Power Management (DIPM). Host Initiated
Power Management (HIPM) has been disabled in the WD Blue 3D NAND SATA SSD.

The device can enter in to the SATA Partial and Slumber low-power modes through
DIPM. In DIPM, the device sends a request to the host to enter into Slumber mode
upon completion of any command.
The device also supports the SATA Device Sleep (DEVSLP) mode. For more

the ATA standard and is not
be data residing in the WD Blue 3D NAND cache that have not been written to the
flash memory. To ensure that the data is properly committed to flash memory, the
WD Blue 3D NAND requires a STANDBY IMMEDIATE command before power down.
This command instructs the WD Blue 3D NAND SATA SSD to write all of its volatile
data cache to
flash memory and returns a GOOD status to the host after its

However, if power is lost without warning – leading to an ungraceful shutdown –
data loss may occur. This may also lead to a longer power-on time for the

Thermal Throttling
Thermal Throttling
To protect the integrity of the data and prevent excessive heat dissipation, the
X600 3D NAND SATA SSD uses an integrated thermal sensor in the NAND to monitor
its critical component temperature. If the sensor temperature rises above the
allowable limit, system performance is throttled until the temperature decreases to
an acceptable level. The X600 returns to full performance when the temperature
returns to a normal range. This performance throttling technique acts as a safety
measure.
The X600 3D NAND SATA SSD reads temperature from the integrated thermal
sensor every one second. The device then autonomously decides which throttling
level is required and reduces performance appropriate to the state.
The following table details the thermal throttling behavior for both the X600 3D
NAND SATA SSD 2.5”/7mm cased and M.2 2280 form factors.

Endurance
Endurance
The endurance (longevity) of the WD Blue 3D NAND SATA SSD is calculated using
JEDEC client workload (JESD219). Endurance is a direct function of user workload
and access pattern. Defined in terms of terabytes written (TBW), endurance
represents the amount of data that can be written to the WD Blue 3D NAND SATA
SSD during the WD Blue 3D NAND SATA SSD lifetime and varies by product
capacity.
