Compare capacity and cache, not just peak speed
Manufacturer speeds are maxima under stated test conditions. They do not show sustained writing after the cache fills. TBW is a write-endurance warranty limit, not a predicted failure date; time limits also apply. Check M.2 length, interface and heatsink clearance in the host manual. Price per TB uses nominal decimal capacity and a confirmed delivered total.
