Package: debian-installer Severity: wishlist Tags: d-i Hello,
Because many consumer grade SSDs are not over-provisioned by the manufacturer it might be nice to have an option, in the automatic partitioning, that reserves a percentage (or a choice of percentages) of a SSD and leaves the space un-partitioned. Reserving unused space on an SSD that is never written to helps prevent write-amplification and so preserves drive performance. The need for this is dependent upon how much/whether the manufacturer has over-provisioned the SSD. See: https://en.wikipedia.org/wiki/Write_amplification If this is implemented it would also probably be prudent to suggest to those creating LVM physical volumes that they may wish to use a partition instead of a raw physical volume so that space can be reserved for manual SSD over-provisioning.
