What is the lifespan of an 8TB SSD?

An 8TB SSD's lifespan typically ranges from 5 to 10+ years for consumer use, determined by its endurance rating (TBW - Terabytes Written), with modern drives designed to handle extensive data writing, often exceeding their rated limits before failure, though factors like usage, drive quality (consumer vs. enterprise), and heat influence longevity. You can estimate its life by dividing the TBW by your average daily data writes.

What is the lifespan of a micro SD card?

Micro SD cards can last from under a year (with heavy use/low quality) to over a decade (with light use/high quality), but generally, expect 2-5 years for normal use, though flash memory cells wear out, so backing up data is crucial. High-endurance cards (like for dash cams) last longer, while constant writing (like video recording) shortens lifespan, but proper shutdown and quality cards (SanDisk, Samsung) help them last longer, with some lasting 10+ years.
