Partition alignment
Apparently, it?s quite important to align the partitions, especially on SSDs. If it?s wrong the disks can perform poorly and wear out more quickly. This disk uses a new technology (TLC) which has an unusual erase block size of 1536kb. I can?t find anywhere online which explicitly says to use that as the value for the sector boundary, but I guess it would be OK.
I did find a question about aligning the partitions for these disks which explains how to use gdisk to do it. The answer suggests to use the lowest common multiple of 1.5 and 2 to be on the safe side: 6MiB. In brief, you use `gdisk /dev/sdX`, hit ?X? for expert mode, ?L? to set the sector alignment, and use 6144 as the value. Hit ?m? to return to normal mode. Now ?p? will show ?Partitions will be aligned on 6144-sector boundaries? so you?re ready to create new partitions.
