SanDisk Optimus GX 7100 2TB NVMe SSD

The SanDisk Optimus GX 7100 is an internal NVMe SSD built for gamers and creators who need fast storage. It uses a PCI-Express 4.0 x4 interface in the M.2 2280-S3-M form factor. The drive delivers sequential read speeds up to 7250 MBps and write speeds up to 6900 MBps.

PCI-Express 4.0 x4 NVMe 2.0 interface

This drive connects through a PCI-Express 4.0 x4 lane running the NVMe 2.0 protocol. That interface sets the maximum throughput ceiling for the controller and 3D NAND TLC memory. Random read performance reaches 1,000,000 IOPS while random write hits 1,400,000 IOPS. The 2TB capacity provides space for large game libraries and project files.

Thermals and power in normal use

The drive operates between 0°C and 85°C without a heatsink. Idle power draw is 5 mW. Average active power measures 3.7W during reads and 3.9W during writes. MTBF is rated at 1,750,000 hours with 1200TB total bytes written endurance.

Questions about this item

What does the 7250 MBps sequential read figure mean when the drive is installed in a system?

The 7250 MBps sequential read is the maximum throughput the Optimus GX 7100 can deliver over its PCIe 4.0 x4 link when reading large contiguous files; real-world speed depends on the host controller, workload and thermal conditions.

How does the PCIe 4.0 x4 interface with NVMe 2.0 protocol limit performance in practice?

The PCIe 4.0 x4 interface caps the drive at a theoretical 8 GBps bandwidth, so the stated 7250 MBps read and 6900 MBps write sit within that ceiling; NVMe 2.0 adds command-set improvements but does not raise the link speed.

Will the M.2 2280-S3-M form factor fit my laptop or desktop slot without a heatsink?

The drive uses the standard M.2 2280-S3-M keying (80 mm length, single-sided components) and ships without a heatsink, so it fits any M.2 2280 slot that accepts single-sided modules; check your device clearance if a motherboard heatsink is present.
