Storm is Silicon Power's lit DDR5 kit, built as UDIMM for a desktop board with room to actually see a taller stick, and it's listed here in two capacities that share one speed grade.
Every listing in the family runs 6400 MT/s CL32, so the number worth comparing across kits is 64GB — 2×32GB at the larger end — since neither the clock nor the latency changes with it.
Because the lighting sits on top of a standard-height heatspreader, check tower-cooler and case clearance before ruling on capacity alone; RGB kits are usually the ones that get crowded out first.
