SanDisk WD_BLACK SN8100 internal SSD 1 TB M.2 2280 PCIe 5.0 x4, 14900/11000 MB/s

The WD_BLACK SN8100 (Powered by SanDisk) is an M.2 2280 internal SSD with a PCIe 5.0 interface for gaming and work PCs. This 1 TB drive reads at up to 14,900 MB/s and writes at up to 11,000 MB/s, uses TLC 3D NAND and supports hardware encryption, so it works equally well as a fast system drive or as a home for your game library.

  • Capacity: 1 TB (1000 GB)
  • Interface and form factor: M.2 2280 (M key), PCIe 5.0 x4, NVMe

  • Use: desktop and laptop, 2.2 mm thick

Description

PCIe 5.0 speed for gaming and creative work

Reads of up to 14,900 MB/s are roughly twice what a fast PCIe 4.0 drive delivers and dozens of times faster than a SATA SSD. Games launch and stream new areas sooner, large video files open in your editor without a pause, and AI models load into memory in seconds. To reach full speed the drive needs an M.2 slot with PCIe 5.0 x4 support.

Write speed that stays close to read speed

Sequential writes of up to 11,000 MB/s mean saving large projects, installing games and copying from another fast drive are quick as well. nCache 4.0 caching keeps writes fast during short heavy bursts. Random reads of up to 1.6 million and writes of up to 2.4 million IOPS keep the system responsive even when it is juggling thousands of small files at once.

TLC 3D NAND and an efficient PCIe 5.0 design

The drive uses TLC 3D CBA NAND, combining speed with reliability. The manufacturer highlights the SN8100's power efficiency: average operating power stays around 7 W, which for a PCIe 5.0 drive means relatively little heat. As a result, speed holds steady for longer even without active cooling. The operating range is 0 to 85 °C and the storage range is −40 to 85 °C.

A slim drive that also fits laptops

Without a heatsink the drive is only 2.2 mm thick and measures 22 × 80 mm. The manufacturer lists both desktops and laptops as intended use, so it can go into a slim notebook as long as its M.2 slot supports NVMe. In a desktop, you can mount it under the motherboard's M.2 heat spreader, which helps keep temperatures down during long workloads.

Hardware encryption

The SN8100 supports hardware encryption, and the manufacturer names TCG Opal among its security features. Data is encrypted by the drive's controller without loading the CPU, and compatible management software can lock the drive. This protects sensitive files if a laptop goes missing or the drive has to be removed from a computer. Windows 10 is listed as the supported operating system.

Who this internal SSD is for

Gamers upgrading a PCIe 5.0 desktop who want short load times; content creators who need a fast system and scratch drive; laptop owners whose machine supports PCIe 5.0 NVMe and who want a slim, quick upgrade; and anyone for whom 1 TB is enough room for the operating system and their main games.

Questions & answers

Will this SSD fit my laptop?

It will if the laptop has an M.2 2280 slot with an M key and NVMe support. The drive is 2.2 mm thick without a heatsink. Full speed requires a PCIe 5.0 x4 slot.

Does it work in a PCIe 4.0 slot?

Yes, PCIe is backward compatible. The drive works in PCIe 4.0 or 3.0 slots, but the slot limits the maximum speed.

Does this drive have a heatsink and RGB lighting?

No. This 2.2 mm version has no heatsink; the SN8100 with a heatsink and RGB lighting is a separate model.

Can the data on the drive be encrypted?

Yes. The drive supports hardware encryption and the manufacturer names the TCG Opal standard, so encryption is handled by the drive's controller without loading the CPU.
