Question: how much tbw do i need?
Answer: 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.
