Estimate How Many Gigabytes a Dedicated Photo Device Should Hold

Estimate how much storage capacity a device built only for keeping photos would need. Lay out your assumptions, show the arithmetic, and recommend a capacity. ```hint Separate the drivers People differ enormously in how many photos they take, so segment them instead of using one average person. Keep photo size and how long the device must last as separate assumptions you can change later. ``` ### Clarifying Questions - Who uses the device: one person, a household, or a business such as a photo studio? - How many years of photos should it hold before the owner needs more space? - Does it store only photos, or videos as well, and are files kept at original quality or compressed? - Should the figure include room for a second copy on the device (for example mirrored drives) in case one drive fails? ### What a Strong Answer Covers - A clear scope (who, what media, how long) chosen before any numbers. - A written equation linking photos taken, size per photo and years kept. - User segments with labeled round-number assumptions and correct arithmetic. - Headroom and redundancy factors that turn raw data volume into a device capacity. - A sanity check, and how the answer moves for video or very large files. ### Follow-up Questions - The owner also wants to keep every video the household records. How does your estimate change, and which assumption matters most? - What capacity tiers would you sell, and how would you pick the default one? - A professional photographer who shoots large RAW files wants the same device.
