4TB PCIe 4.0 NVMe drive

The SanDisk Optimus GX 7100 is a 4TB internal SSD built to the M.2 2280-S3-M form factor. It connects over a PCI-Express 4.0 x4 link using the NVMe 2.0 protocol. The drive uses 3D NAND TLC memory and ships without a heatsink.

Suits PCIe 4.0 slots with 4TB needs

This drive fits desktops and laptops that have an M.2 2280 slot wired for PCIe 4.0 x4 and can accommodate a single-sided module. Systems limited to PCIe 3.0 or shorter M.2 keys will not reach the stated speeds. Builds that require a factory-fitted heatsink should consider other models.

Check slot key length and thermal plan

Verify the motherboard or laptop provides an M.2 2280-S3-M socket with PCIe 4.0 x4 electrical wiring. Confirm the operating temperature range of 0 to 85 °C matches the chassis airflow. Ensure the firmware supports NVMe 2.0 features before installation.

Questions about this item

What M.2 slot key and length does my motherboard need for the Optimus GX 7100 4TB?

The drive uses the M.2 2280-S3-M form factor, so the slot must accept 80 mm modules with an M-key connector.

Will the Optimus GX 7100 run at full speed in a PCIe 3.0 x4 slot?

It is a PCIe 4.0 x4 NVMe 2.0 drive; in a 3.0 slot it will operate at PCIe 3.0 speeds instead of the rated 7000 MBps read and 6700 MBps write.

How can I verify the Optimus GX 7100 is delivering its rated random performance after installation?

Run a 4 KB random read/write test and look for results near 900,000 IOPS read and 1,350,000 IOPS write.
