| // expectations and encourage use of devices comparable to |
| // internal storage performance.) |
| |
| // However, since then, internal storage has started moving from |
| // eMMC to UFS, which can significantly outperform adopted |
| // devices, causing the speed warning to always trigger. To |
| // mitigate this, we've switched to using a static threshold. |
| |
| // The static threshold was derived by running the benchmark on |
| // a wide selection of SD cards from several vendors; here are |
| // some 50th percentile results from 20+ runs of each card: |
| |
| // 8GB C4 40MB/s+: 3282ms |
| // 16GB C10 40MB/s+: 1881ms |
| // 32GB C10 40MB/s+: 2897ms |
| // 32GB U3 80MB/s+: 1595ms |
| // 32GB C10 80MB/s+: 1680ms |
| // 128GB U1 80MB/s+: 1532ms |
| |
| // Thus a 2000ms static threshold strikes a reasonable balance |
| // to help us identify slower cards. Users can still proceed |
| // with these slower cards; we're just showing a warning. |
| |
| // The above analysis was done using the "r1572:w1001:s285" |
| // benchmark, and it should be redone any time the benchmark |
| // changes. |
