SanDisk Optimus GX 7100 Spec and Price in the United States
The GX 7100 drops down to PCIe 4.0 without a DRAM cache, landing at 7,250/6,900 MB/s sequential, numbers nearly identical to WD's own SN7100 given the shared engineering lineage. Random write IOPS still reach 1.4 million despite going DRAM-less, and its 1,200TB endurance rating matches the pricier GX PRO 8100 tier for tier. It reads as the mainstream-to-upper-mid choice for buyers who want gen4 speed without paying for PCIe 5.0 headroom they won't use.
Tied 26th of 106 models in the SSD catalog on Sequential read — 3 models share this figure. Tied 16th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.
