## Long description

Western Digital 4 TB M.2 PCI Express 4.0 SN7100 is a high-capacity NVMe SSD in M.2 form factor designed for desktop and laptop systems that support PCIe 4.0. The drive offers very high sequential read speeds up to 7000 MB/s and sequential write speeds up to 6700 MB/s, and uses 3D TLC NAND to balance performance with endurance. With 4 TB of usable capacity it provides space for large game libraries, multimedia projects and heavy application data while fitting compact M.2 slots.
Advantages
The SN7100 delivers sustained high throughput and low latency typical for PCIe 4.0 NVMe drives, reducing load times for games and accelerating file transfers. 3D TLC NAND combined with SSD controller optimizations provides a balance of performance and durability. Its M.2 form factor enables direct motherboard installation without additional cables, saving space inside systems. The large 4 TB capacity reduces the need for external storage solutions for bulky files.
Suitable for
 High-performance gaming systems requiring fast game load and install times
 Content creation workflows such as video editing, 3D rendering and large asset libraries
 Workstations and desktops running virtualization or database applications with heavy I/O
 Users who need a high-capacity internal drive for media storage and backups

How to use
Install the M.2 SSD into an available M.2 slot on a compatible motherboard that supports PCIe 4.0 for optimal performance. Power down the system, ground yourself to avoid electrostatic discharge, insert the module at the correct angle and secure it with the mounting screw. After booting, initialize and format the drive in the operating system's disk management utility, then transfer data or install applications. For laptops, verify physical clearance and thermal considerations before installation.
Usage recommendations
To maintain performance and longevity, ensure proper system cooling and keep firmware up to date via the manufacturer's support tools. Use the drive as a primary location for applications and active projects, and maintain regular backups for critical data. If the system supports PCIe 4.0, enable it in BIOS/UEFI for best throughput; otherwise the drive will operate at the highest supported interface speed.
