For me I have things like sda1 sdb2 sdc3 sdd4 and I align the partitions to the physical slot.
What do you do when it comes to 5,... (as MBR only supports 4 primary partitions ;-) ?
Then you make something an extended partition.
This makes it easier to see what is the failed disk; "sdc3 has fallen out of the array; that's the disk in slot 3".
Because today's sdc may be tomorrow's sdf depending on any additional disks that have been added or kernel device discover order changes or whatever.
That's why I like the [block] device naming strictly derived from topology of machine (e.g. FreeBSD does it that way), then you know, which physical drive (or other block device, e.g. attached hardware RAID) a device /dev/da[x] is. I remember hassle when Linux switched numbering of network
How? I've had them move around on a non-RAID m/b (for example, a drive fails, and you put one in an unused bay, and then you've got, say, sda, sdc and sdd, no sdb, until reboot), and even then, it's *still* a guessing game as to whether hot-swap bay upper left, lower left, upper right lower right are sda, sdb, sdc, sdd, or sda, sdc, sdb, sdd, or, for the fun one, lower right is sda....
