It's a 64x difference. And even that is grossly understating it because most database systems feature write coalescing. It's actually "ironic" in that database systems were built to avoid random IO because it was glacially slow on spinning rust storage. They do everything possible to avoid it, and in actual, empirical metrics running databases on flash the write amplification has been very low, and hardly mirrors the claims throughout this thread. |
