Capacity and interface

The SanDisk Optimus GX 7100 is a 500GB internal solid state drive using the M.2 2280-S3-M form factor. It connects through a PCI-Express 4.0 x4 interface running the NVMe 2.0 protocol. The drive employs 3D NAND TLC memory components and ships without a heatsink.

Who this suits

This SSD suits PC builders and laptop owners who want faster game loading and responsive creative workflows on a PCIe 4.0 platform. The power-efficient design draws 5 mW idle and around 3.5 W active, making it practical for handheld gaming consoles and thin notebooks. Buyers who need a heatsink pre-installed or who require higher endurance than 300 TBW should consider other options.

Deciding specification

The single specification that decides fit is the M.2 2280-S3-M form factor combined with the PCI-Express 4.0 x4 interface. Your motherboard or device must provide an M-keyed slot wired for four lanes of PCIe 4.0 to achieve the stated 6800 MBps read and 5800 MBps write speeds.

Questions about this item

Does the SanDisk Optimus GX 7100 500GB include a heatsink or mounting screw, or must they be bought separately?

The drive ships without a heatsink. A motherboard M.2 mounting screw is also not included; reuse the screw from your board or purchase one separately.

How do I decide between the 500GB Optimus GX 7100 and a larger capacity in the same series?

Choose 500GB if you need a single fast NVMe drive for the OS and a handful of active titles; step up to 1TB or 2TB when your library grows beyond that footprint.

What does the 6800 MBps sequential read figure mean once the SSD is installed in my PC?

It represents the peak throughput the controller can sustain on a PCIe 4.0 x4 link; real-world game loads and file copies will typically run lower depending on workload and thermal conditions.
