Decision Lantern

Cameras and audio calculator

External SSD versus HDD for video

Reviewed Skip to the planner

Editors choosing a working drive. The decision this page isolates is narrow on purpose: pick a portable ssd, hdd, or raid class from project size and whether you edit from the drive. Payload, channel count, and distance decide the class. A sample photo does not.

This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Samsung, SanDisk, and OWC. It produces an explainable class so Samsung T9 Portable SSD, SanDisk Desk Drive SSD, and OWC Envoy Pro FX can be compared as examples of that class.

The working method is: Prefer a fast SSD when editing from the disk and an HDD or DAS when the job is mainly archive. Planning notes are grounded in SD Association. This page does not quote a price or rank a brand.

How to use this calculator

Editors choosing a working drive. Pick a portable SSD, HDD, or RAID class from project size and whether you edit from the drive. If you can answer project size in tb, this page can produce a class you can shop against.

What this page will not do

  1. Enter the planning inputs

    Choose a drive category by recording project size in tb. Use real measurements or counts, not a rounded marketing number.

  2. Mark the constraints that change the class

    Only check need to edit directly from the drive when that constraint is actually present. Extra checks can jump the class.

  3. Read the drive category

  4. Compare official pages, then verify

    Open the official page for each example in that class. Confirm current specifications, dimensions, and terms. Decision Lantern does not quote a live price or complete an install review.
