WD Black SN7100 2TB for a compatible desktop or laptop

The SN7100 was designed with laptops and gaming handhelds in mind, but physical fit still matters. This is an 80 mm M.2 2280 drive; it requires a slot and mounting position that support that length. The module is rated at 80 x 22 x 2.38 mm and 5.8 g. Check the computer's service manual for NVMe support, cooling clearance and installation access.

TLC NAND and Gen 4 bandwidth

The drive combines TLC 3D NAND with a PCIe Gen 4 x4 connection. Random performance reaches up to 1,000,000 read IOPS and 1,400,000 write IOPS. Maximum figures depend on the host, workload and usage conditions, so they are not guaranteed transfer speeds for every file.

A larger working library

Its 2 TB capacity gives you space to keep installed games alongside updates, recordings and project files. Actual usable space is lower after formatting and system overhead. The 1200 TBW rating describes write endurance under the manufacturer's specified client workload.

Monitoring from Windows

The manufacturer's Dashboard software supports drive-health checks, performance monitoring and firmware updates on Windows. The SN7100 has a DRAM-less design. Back up important data separately and check available firmware before moving an existing operating-system installation.

Does the WD Black SN7100 2TB include a heatsink?

This version is supplied without a separate heatsink. Use the cooling arrangement specified for your motherboard or computer, and check clearance before installing an additional cooler.

Can it work in an older PCIe system?

The manufacturer lists backward compatibility with PCIe Gen 3 and Gen 2 connections at x4, x2 or x1. The slot must support PCIe NVMe storage, and the connection limits available performance.

Is this the 1TB or 2TB SN7100?

This listing is the 2TB WDS200T4X0E model. Its sequential ratings are up to 7250 MB/s read and 6900 MB/s write, with 1200 TBW endurance.

What manufacturer warranty applies?

The WD Black SN7100 2TB carries a limited five-year manufacturer warranty or its maximum endurance limit, whichever comes first. Region-specific warranty terms and eligibility apply.
