Buffer Performance

How to Calculate A Cameras Buffer Depth & Write Speed

1. On Full Burst, RAW, Sony shoots at 11 frames per second, for 2 full seconds, or 22 total files, each at 24MB each, or a total of 528 MB of files captured during those 2 seconds.

2. Once the buffer is full, the camera allows you to take another picture, as the buffer is clearing. So the assumption is you can take another picture as soon as that space becomes available, but if we know that we took 7 additional RAW files over 4.8 seconds, we can calculate:

7 x 24MB = 168MB written in 4.8 seconds, or 35MB/s. Write speeds are typically written in bits, which we find by multiplying that by 8, so the write speed of the A6300 is ~ 280 Mb/s.

Coming back to the total number of MB captured during those 2 seconds of burst, we subtract what should be the total amount a data written during those 2 seconds, or 35MB x 2 = 70MB.

528MB - 70MB = ~ 458 MB Buffer Space
