A new log-aggregation server is projected to write its entire 800 GB data set roughly ten times every day. The hardware vendor groups its enterprise SATA SSDs into Read-Intensive (≤ 1 DWPD), Mixed-Use (≈ 3 DWPD), and Write-Intensive (≥ 10 DWPD) categories, where DWPD represents the number of full-drive writes the device can sustain daily over a five-year life. Which SSD category should be selected to minimize premature wear in this write-heavy deployment?
Read-Intensive (≤ 1 DWPD)
Mixed-Use (≈ 3 DWPD)
Write-Intensive (≥ 10 DWPD)
Endurance is the same for all SSDs, so any category will suffice
The application will subject each drive to about ten complete rewrites per day. Only SSDs rated as Write-Intensive are engineered for that level of endurance (≥ 10 DWPD), meaning they are warranted to survive at least ten full-capacity writes every day for five years. Read-Intensive drives (≤ 1 DWPD) and Mixed-Use drives (≈ 3 DWPD) would exceed their design limits and wear out early, and endurance clearly does vary among SSD classes-so choosing any class indiscriminately is not acceptable.
