\nHEED THE DATA LOSS WARNING! There are a number of extremely buggy SSD models out there (like almost all the Samsung 8* and various Crucial models) that will permanently delete the wrong data ('https:\/\/blog.algolia.com\/when-solid-state-drives-are-not-that-solid\/') when issuing TRIM commands. The bug is not dependent on queued TRIM, it happens even when using the non-queued version. All the Samsung SSDs beginning with a \"8\" (840 and 850, both EVO and Pro) are known to have the data-destroying TRIM bug and TRIM is blacklisted on those drives on other platforms.\n<\/p><\/blockquote>\n
