I'll be getting a 13" MBP 2010 model with SD reader.
I'd like to utilize as additional storage.
 
I will be sticking a smallish SSD and installing current HD in optical bay.
I'm not buying a new / larger SSD.
 
I use the SD card for OS testing... currently got a El Capitan installed on a SD card so I don't need to mess with the partitions on my main drive. Also use it as a back up (but never had to use it yet) if my main OS dies at a gig I can boot from the SD card instead.

How do you install an OS to an SD card? Also, how do you boot to that drive?
 
SD cards have awfully slow random read/write times. Running an OS or any app that has a lot of I/O to the drive will cause it to crawl. I wouldn't use an SD card for anything but music/video file storage.

That's all I use them for. Copying files to an SD card sometimes seems slow but copying from sometimes seems much faster.

There was one time I booted a MBP from an external hard drive that was originally in the MBP and that was extremely slow.
 
I only use it as a last resort backup if my main OS dies at a gig (and some testing) , I wouldn't use it as a main OS drive .
