Overview

The SanDisk Enterprise SN861 is aimed squarely at the data center, not the desktop. This 3.84TB model rides the PCIe Gen5 NVMe 5.0 bus and arrives in the E1.S form factor, a slim 15mm design that has become a favorite for high-density storage servers. It belongs to a capacity range that climbs to 15.36TB, so buyers standardizing a fleet can pick the size that fits without switching drive families. The target buyer is clear: system builders and IT teams provisioning storage where bandwidth, density, and reliability all matter at once.

On construction and ownership, the SN861 stacks the features enterprise operators tend to prioritize. Power loss protection helps preserve data that is mid-write when power drops, and end-to-end data path protection watches for corruption along the way. Security spans SE, ISE, and TCG encryption, covering a range of compliance postures. Manufactured by Western Digital under the SanDisk brand, the drive is also engineered for low power consumption, a detail that compounds meaningfully when a rack holds dozens of units. It is a purpose-built component, and its practicality is measured in uptime and efficiency rather than everyday convenience.

Frequently Asked Questions

It uses the E1.S 15mm form factor and a PCIe Gen5 NVMe 5.0 interface, making it intended for high-density enterprise servers and data center storage rather than consumer PCs or laptops.
The drive includes power loss protection to safeguard in-flight data, along with end-to-end data path protection that guards against corruption as data moves through the drive.
The SN861 offers SE, ISE, and TCG security and encryption options, giving enterprise buyers flexibility to meet a range of compliance and data-protection requirements.
No. The 3.84TB model sits within a broader SN861 family that scales up to 15.36TB, so higher-capacity single-drive options exist under the same product line.
It is engineered for minimal power draw to optimize efficiency and reduce operational costs, which matters most at data center scale where per-drive wattage adds up across many bays.
The drive is manufactured by Western Digital Corporation under the SanDisk brand name.
