    As per https://techcommunity.microsoft.com/t5/storage-at-microsoft/understanding-ssd-endurance-drive-writes-per-day-dwpd-terabytes/ba-p/426024
    If you choose to measure in TBW, we recommend 4 TBW per day of lifetime. Spec sheets often provide TBW cumulatively, which you’ll need to divide by its lifetime. For example, if your drive has a warranty period of 5 years, then 4 TB × 365 days/year × 5 years = 7,300 TBW = 7.3 PBW total.
