Western Digital WD 2TB 3D NAND SATA III 2.5" Internal SSD (Retail) - Manual (Page 7)

2 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.
