 A typical practice for personal computers is to have each partition aligned to start at a 1 MiB (= 1,048,576 bytes) mark, which covers all common SSD page and block size scenarios, as it is divisible by all commonly used sizes - 1 MiB, 512 KiB, 128 KiB, 4 KiB, and 512 B.Modern operating system installation software and disk tools handle this automatically.The ext4, Btrfs, XFS, JFS, and F2FS file systems include support for the discard (TRIM or UNMAP) function.
