DB LabsThe Quick Verdict
In 2026, the sweet spot for most users is 256 GB — the new default on iPhone 17 and the best balance of price and room to grow. If you shoot lots of 4K video or travel with offline movies, step up to 512 GB. Reserve 1 TB for photographers, videographers, and power users who record ProRes or ProRAW regularly. 2 TB (available only on iPhone 17 Pro Max) is overkill for 99% of users. Skip 128 GB if you can — you'll fill it within a year on an active iPhone.

By User Type
Light User (128 GB)
You check email, browse social media, take occasional photos, and use iCloud Photos. 128 GB holds a year or two of casual shots before you need to delete old ones. Use with iCloud subscription (50-200 GB) for photo offloading.
Typical User (256 GB)
You take daily photos, record short videos, keep 2-3 dozen apps, and stream music/video. 256 GB is comfortable for 3-5 years without active management. The new default on iPhone 17 recognizes this reality.
Active Shooter (512 GB)
You take multiple photos daily, record family videos, travel with offline media, and play large games (Genshin Impact, Call of Duty Mobile). 512 GB lasts the full 5-7 year lifespan of a flagship iPhone.
Photographer / Videographer (1 TB)
You shoot in ProRAW regularly (50-75 MB per photo), record 4K 60fps video, or use the iPhone as your primary camera for client work. 1 TB is the minimum for sustained pro use without constantly offloading.
Pro Videographer (2 TB)
You record ProRes 4K (6 GB/min) for long sessions and need local storage for editing. 2 TB is only available on iPhone 17 Pro Max. If you're shooting ProRes all day, consider recording to an external USB-C SSD instead — it's cheaper and more flexible.
iCloud vs Onboard Tradeoff
You can save $100-$400 upfront by buying a smaller iPhone and paying for iCloud storage instead. Math: $100 storage upgrade vs $2.99/mo for 200 GB iCloud = 33 months breakeven. If you keep your iPhone 5+ years, onboard storage wins. If you upgrade every 2 years, iCloud wins.
