What are the sequential read and write speeds of the WD_BLACK SN850X 1TB?

The drive achieves up to 7300 MB/s sequential read and 6300 MB/s sequential write speeds via PCIe Gen4 x4 NVMe 1.4 interface. These performance levels support high-bandwidth tasks like 4K video editing and large file transfers, as per SanDisk Official Datasheet.

What is the random IOPS performance?

Random read reaches 800000 IOPS (4KB) and random write up to 1100000 IOPS (4KB), enabling low-latency access for databases and multitasking. This outperforms many Gen3 drives, ideal for virtualized environments per SanDisk specs.

Does it include a heatsink and what are the dimensions?

Yes, it features an integrated heatsink. Dimensions are 80 mm length, 23.4 mm width, 8.8 mm height, weighing 24 g in M.2 2280 form factor. Ensures thermal throttling prevention during sustained loads.

What is the endurance rating and operating temperature?

Endurance is 600 TBW with operating temperature from 0°C to 85°C. Built on TLC 3D NAND, it handles write-intensive workloads reliably in enterprise and consumer setups.

Which operating systems are supported?

Compatible with Windows 8.1, 10, 11, and PlayStation 5 (heatsink model, software 21.02-04+). M.2 2280 form ensures plug-and-play in most modern motherboards.

What NAND technology and interface does it use?

Utilizes Western Digital TLC 3D NAND with PCIe Gen4 x4 (NVMe 1.4), M.2 M-key connector. Provides 1TB capacity optimized for gaming and professional storage needs.
