Do not use MBR (or manually do all to align).
63 - not 4k aligned.
To create the above shown partition layout I have not used gpart(8); I
just said:
# fdisk -I /dev/ada0
# fdisk -B /dev/ada0
...
What is wrong with this procedure?
The filesystem partitions end up at locations that aren't even multiples
of 4K. This can reduce performance. How much probably depends on the
SSD.
But this is then rather a bug in fdisk(8) and not a PEBKAC, or? :-)
A bug in the design of MBR. Which probably can be forgiven, considering
when it was created and the other problems with it. :)
gpart's alignment option can be used with MBR slices and bsdlabel
partitions._______________________________________________
