Western Digital® PC SA530 3D NAND
SATA SSD
Exceptional Storage Options for a Broad Range of
Computing Applications
High Performance and High Capacity for Computing
Based on Western Digital 96-layer 3D NAND, the Western Digital PC SA530 3D NAND SATA
SSD delivers high performance, high capacity, and superior endurance. In capacities of up
to 1TB, the Western Digital PC SA530 achieves this while expending less power than our
previous generations of SATA SSDs.
The Western Digital PC SA530 combines Western Digital’s state-of-the-art 96-layer
3D NAND technology with our proven SSD platform. It also incorporates nCache
a tiered caching technology designed to improve responsiveness for corporate and
consumer workloads. nCache 2.0 uses a combination of both SLC (single level cell)
and TLC flash blocks to improve endurance, increase efficiency, and boost per formance.
Writing data first to the SLC cache reduces write amplification on the TLC blocks.
With on-the-fly hardware-based encryption, the Western Digital PC SA530 (SED models
only) provides complete end-to-end encryption to the storage, system and
infrastructure. It supports password protection, AES-256-bit encryption, TCG-OPAL
2.01 standard and PSID.

2.0,
Lower Power, Higher Capacity and Thin Form
Factors Offers Design Flexibility
The Western Digital PC SA530 is optimized for the demanding power management
requirements of ultra-thin and small form factor products.
It features Device Sleep (DEVSLP), more frequent use of low-power modes, and faster
transitions between various power modes. Also included for superior error recovery,
DataGuard
With a variety of design and integration options for manufacturers and systems builders,
the Western Digital PC SA530 is available in either an SATA 2.5”/7mm cased or an M.2 2280
form factor, with capacities of 256 gigabytes
