As in subject - do those drives report “Deterministic read zero after trim” correctly ?
All modern drives behave this way - and basically any older model from past few years reported this feature (or at least older “Deterministic read after trim”). For reasons unknown (marketing ? encryption ?) recent models from other vendors (we tested crucial’s mx500s, adata’s sx950u, samsung’s 950s and 960s) stopped reporting rzat/drat altogether.
This makes it particularly frustrating when you put such disks behind e.g. LSI controllers that block trims unless rzat or drat is supported.
