Quick Answer
Premium NVMe is worth it for VR fitness only when sustained write speed or capacity is the real bottleneck. A Gen5 2TB drive at 12,000MB/s+ helps large-file scratch work; for most tasks a 2TB Gen4 at ~5,000MB/s (about R1,900 to R2,900 currently stocked at Evetech) delivers nearly the same felt speed for less.
Where Premium Drives Earn Their Price
Premium NVMe buys you three things: higher sustained writes for moving very large files, larger capacity in one slot, and better endurance (TBW) for write-heavy work. Gen5 peaks at 12,000MB/s+ versus Gen4's ~5,000MB/s, but games and apps barely show the difference because they read in small bursts, not one giant stream. The premium pays off when you regularly copy 50GB-plus files, run a scratch disk, or need a 4TB drive in a single slot. Otherwise a quality 2TB Gen4 is the smarter spend.
NVMe For VR Fitness Sessions
VR fitness titles load levels and stream assets that a fast NVMe handles without the wait that breaks momentum mid-workout. A 1TB-2TB Gen4 drive at ~5,000MB/s loads VR scenes quickly and keeps the headset's frame pacing smooth alongside the GPU. Premium Gen5 speed is rarely the limit here; capacity for several VR titles matters more, so a 2TB Gen4 is the value pick.
FAQ
Is Gen5 NVMe worth it over Gen4 for gaming?
Not really. Games load only a second or two faster on Gen5, and the drives run hotter and cost more. A 2TB Gen4 at ~5,000MB/s is the smart pick for gaming; save Gen5 (12,000MB/s+) for heavy file work.
How much NVMe storage do I actually need?
2TB is the practical sweet spot. Modern games run 80GB to 150GB each, so 1TB fills fast. A 2TB Gen4 (about R1,900 to R2,900 currently stocked at Evetech) holds a healthy library plus the OS.
Do I need a heatsink on my NVMe drive?
For Gen4 a heatsink is nice-to-have; for Gen5 it is essential. M.2 drives throttle past roughly 70C, so a heatsink or a motherboard M.2 cover keeps speeds steady during long transfers.
