At $129.99, this 500GB Gen 4 drive lands well under its 30-day average of $159.05 and its 90-day average of $167.65. The all-time low on this model is $136.99, so today's price actually beats that by $7.

If you have been watching NVMe prices during Prime Day. This is the lowest this drive has ever been.

What You're Getting

The Optimus GX 7100 is a PCIe Gen 4 M.2 2280 SSD built on Sandisk's 8th generation BiCS TLC 3D CBA NAND. Sequential read speeds hit up to 7,250 MB/s and writes reach 6,900 MB/s on the 1TB and 2TB models, with random read/write performance up to 1M/1.4M IOPS. The 500GB variant still delivers Gen 4 speed for faster game loads and DirectStorage support. Sandisk Dashboard software includes a Game Mode toggle, and the drive ships with Acronis True Image for Sandisk migration tools.

Who This Is For

Best for anyone building or upgrading a Gen 4-compatible system who wants a modern boot drive or dedicated game library at a Prime Day price. Also a strong pick if you need an extra NVMe slot filled without spending over $150.

If your motherboard only supports Gen 3, you will still get full Gen 3 speeds, but a cheaper Gen 3 drive makes more sense.

The Caveat

This is the 500GB capacity, so heavy game installers or creative project files will fill it fast. The 1TB and 2TB versions offer better value per gigabyte if your budget stretches further.

Final Verdict

At $129.99, this undercuts its own all-time low and lands well below what it typically costs. If you need a fast Gen 4 drive during Prime Day. This is the price to move on.
