You're mixing Si units and IEC units[1]. The article's measurement of 278 GB (sic) is really 278 GiB. 1280 horizontal resolution x 720 vertical resolution x 3

You're mixing Si units and IEC units[1]. The article's measurement of 278 GB (sic) is really 278 GiB.
1280 horizontal resolution x 720 vertical resolution x 3 8-bit bytes per pixel x 30 frames per second x 3600 seconds per hour is 298,598,400,000 bytes per hour. 1GiB (1,024 bytes x 1,024 KiB x 1,024 MiB) is 1,073,741,824 bytes. Dividing that out gives ~278.09 GiB.

- lightedman 7y agoI'm responding directly to the GB claim. I'm very well-aware of binary prefix (in fact several of my other online names are those very words) and the general industry-wide mix-up that is used on the common consumer is to start with KiB and then just run that in plain units of 1,000 for MB and GB, which is what I went with.
