Erasure coding: 2 real scaling case studies

2 of the 94 engineering write-ups in our database are tagged with the technique "erasure coding". They come from 1 company (Dropbox) and were published in 2019 (1 undated). Stack that shows up most often in these stories: Custom storage (2). 1 of the 2 state concrete scale numbers, for example "500 PB" (Dropbox). Each card below links to our short summary and the original post.

Dropbox's Magic Pocket cold tier uses erasure coding for rarely read data. For other ways to move cold data to cheaper storage, see tiered storage examples.
