The SanDisk Optimus GX 7100 is a 4TB PCIe 4.0 NVMe drive in the M.2 2280 form factor, rated at up to 7,000MB/s sequential read and 6,700MB/s write. It uses 8th-generation BiCS TLC NAND, SanDisk nCache, and supports Microsoft DirectStorage. The 4TB capacity suits large game libraries and content work that outgrows 1TB and 2TB drives, and the power-efficient design targets laptops and handhelds. It is a high-capacity, high-speed drive rather than a budget pick; rivals in this class trade small speed differences and price, and the five-year warranty and SanDisk Dashboard software round it out.
