And /dev/sda doesn't really say much, of course.

I often have to remember which drive was how big and made by whom to
untangle this question. That's why you want to use the UUIDs as much
as you can. With the manufacturers, sizes, knowledge of how the RAID
was set up, and UUIDs, you can use /dev/disk/* to figure out what you
need.
