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 workloads.
The WD Blue 3D NAND SATA SSD is optimized for the demanding power management requirements of Ultrathin and small form factor products. It features Device Sleep (DEVSLP), more frequent use of low-power modes, and fast transitions between various power modes.
The WD Blue 3D NAND SATA SSD also features a robust error-handling mechanism technology which uses a page-level striping with distributed parity for an added layer of data protection. This mechanism thus recovers errors, without interrupting user data flow that other traditional error correction mechanisms cannot.
Available in either a SATA 2.5"/7mm cased or an M.2 2280 form factor, the WD Blue 3D NAND SATA SSD offers drive capacities of 250 gigabyte ^1 (GB), 500GB, 1 terabyte ^2 (TB), and 2TB.

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 is superior to the HDD 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 on-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 flash life expectancy. 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 flushing the SLC blocks to the TLC storage or reorganizing the 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.
Tiered Caching
The WD Blue 3D NAND SATA SSD uses a tiered caching structure to improve write performance and endurance.
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 flash memory 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 flash write cache
■ Mass storage — TLC NAND flash
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 flush to mass storage when exceeding their threshold.
Low-Density Parity-Check (LDPC)
An enhancement introduced with the WD Blue 3D NAND SATA SSD is the low-density 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 information, refer to the SATA revision 3.2 specification available at www.t13.org
General Product Specifications
Interface
The device interface complies with the Serial ATA standard published by ANSI. It complies with the SATA 6Gb/s (rev. 3.2) specification and supports ATA-8 Command Set ACS-4. It is also backwards compatible with SATA 3Gb/s (rev. 2.0) and SATA 1.5Gb/s (rev. 1.0).

Graceful Power-off Requirements
On most operating systems, Write Cache is enabled by default. This is a feature of the ATA standard and is not specific to WD Blue 3D NAND SATA SSDs. There may 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 successful completion. This command is handled transparently by most operating systems during the shutdown sequence (e.g., hibernation, shutdown, and standby).
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 subsequent power-up.
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
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.

Reliability Characteristics
Uncorrectable Bit Error Rate (UBER)
The uncorrectable bit error rate is one error per 10^16 bits read.
Mean Time to Failure (MTTF)
Mean Time to Failure (MTTF) ^23 is a reliability figure that indicates the expected time to failure of non-repairable electronic equipment. Estimates of MTTF made using a prediction methodology based in accordance with the Telcordia Special Report SR-332. The prediction is based on a Parts Stress Analysis.
Quality levels were defined as industrial grade (I) for all of the components. The detailed prediction for the system was performed at a temperature of 25^ C in a GB (ground, benign) environment.
The MTTF for all WD Blue 3D NAND SATA SSD form factors and storage capacities is 1,752,000 hours.
