WD_BLACK 1TB SN850 NVMe Internal Gaming SSD Solid State Drive with Heatsink - Works with PlayStation 5, Gen4 PCIe, M.2 2280, Up to 7,000 MB/s - WDS100T1XHE
Overview
The WD_BLACK SN850 1TB NVMe with Heatsink is a high-performance M.2 2280 SSD built for gamers and power users who need the fastest local storage available. Using PCIe Gen4 x4 bandwidth, the 1TB model delivers up to 7,000 MB/s read and 5,300 MB/s write, dramatically cutting game load times and speeding asset streaming for content creation. The factory-fitted aluminum heatsink helps manage temperatures under sustained loads, making this drive a common choice for PlayStation 5 owners and desktop builders who want plug-and-play expansion without external cooling. It’s optimized for consumer gaming and workstation workloads — not designed for NAS or enterprise server use — and comes with Western Digital’s software tools and a limited warranty for peace of mind.
Key Features
- Interface: PCIe Gen4 x4 NVMe (backward compatible with PCIe Gen3, but Gen4 required for peak speeds).
- Form factor: M.2 2280 (22 x 80 mm) — fits standard M-key M.2 slots on desktops and many consoles; double-check physical clearance when installed with heatsink.
- Performance (1TB model): Sequential read up to 7,000 MB/s and sequential write up to 5,300 MB/s for accelerated load times and transfers.
- Thermal design: Integrated factory-fitted aluminum heatsink to improve heat dissipation and reduce thermal throttling during prolonged heavy use.
- Capacity & support: Available up to 2TB for large game libraries; supported by WD Black Dashboard for firmware updates and performance monitoring and covered by a limited warranty.
Pros & Cons
Pros
- Top-tier sequential performance: up to 7,000 MB/s read and 5,300 MB/s write (1TB model) for minimal load times and fast file transfers.
- Factory-installed heatsink reduces thermal throttling during long gaming or creative sessions.
- M.2 2280 form factor and PCIe Gen4 x4 interface fit modern motherboards and PS5 expansion (check Sony guidance for clearance).
- Available in up to 2TB capacity so you can store multiple large titles without frequent deletions.
- Includes WD software (Dashboard) for firmware updates, performance monitoring, and drive management.
Cons
- Higher cost per GB versus PCIe Gen3 and SATA SSDs.
- Heatsink adds height and may not fit some small laptops or systems with strict M.2 clearance — verify before buying.
- Performance limited to PCIe Gen3 speeds on older systems; you won’t reach Gen4 peak unless your platform supports it.
- Not intended for continuous-write, multi-user NAS or enterprise server environments.
Recommendations
- PC gamers who want the fastest local storage for triple-A titles and quick load times on PCIe Gen4-capable motherboards.
- PlayStation 5 owners seeking an internal, factory-heatsinked SSD that meets Sony’s performance requirements — verify physical fit before installation.
- Content creators and streamers who need a fast scratch disk for video editing, asset streaming, or working with large files.
- Desktop builders upgrading system responsiveness and game storage where sustained throughput and thermal control matter.
