Any reference about the &#x27;no discard&#x27; advice ? I used it for a while on an Intel 520 80GB SSD, it was fine at first but when I reached low free space (~1GB) the SSD became sluggish, which isn&#x27;t unexpected, but even after freeing 4GB it was still slow.
Manually trimming reported &#x27;0 Bytes trimmed&#x27;. Only after remounting the disk without `discard` and then `fstrim --all` that the SSD got decent performances back.
