How many photos fit on that?
Photo counts are the only storage unit most people can picture. Here is what a drive actually holds.
32,000 × a phone photo
128 GB ÷ 0.004 GB = 32,000 photos.
Reference figures are measurements and are rounded; the unit conversion behind them is exact.
| Reference | Size | Yours ÷ theirs | Note |
|---|---|---|---|
| phone photo | 0.004 GB | 32,000× | A 12 MP JPEG |
| MP3 song | 0.005 GB | 25,600× | |
| camera RAW file | 0.03 GB | 4,267× | |
| lossless song | 0.035 GB | 3,657× | |
| minute of 4K video | 0.35 GB | 366× |
Worth knowing
- A 128 GB phone holds about 32 000 JPEGs — or 6 hours of 4K video, which is why the video is what fills it.
- RAW files are seven times larger than JPEGs from the same sensor, because they keep the sensor data instead of throwing most of it away.
Frequently asked
How many photos fit on 128 GB?
About 32 000 phone JPEGs at 4 MB each, or roughly 4 200 camera RAW files at 30 MB.
Why do photos vary so much in size?
JPEG compression depends on the content. A picture of a plain sky compresses to a fraction of the size of one of a leafy tree, at identical resolution.
