If I put my mac hard disk system with with bootcamp in a USB caddy, after replacing it with an SSD, will it appear as 2 drives when plugged in?

Few general questions about PyQwt

I consider to use PyQwt for plotting realtime data as a part of my thesis work, but I have doubts about it for a few reasons:
Last release was in 2009
There are very few questions and most of them are dated 2009 - 2012. Looks like that more experienced people use it rare for some reason.
Is it still a good choice for that sort of things for unexperienced programmers as it's not my main occupation?If I put my mac hard disk system with with bootcamp in a USB caddy, after replacing it with an SSD, will it appear as 2 drives when plugged in?

I'm going to replace my MacBookPro system drive / hard disk with an SSD. I will then re-install MacOS and Windows via bootcamp.
The original drive will be put in a USB caddy to be used as an external drive.
My system drive has bootcamp on it, so it has been partitioned HFS+ / NTFS
If I plug this drive as an external drive via USB will 2 (two) drives appear on my Mac Desktop? One for the MacOS partition and one for the NTFS partition?
(When I've put a partitioned drive in a USB external caddy and then plugged it into a Windows machine, several drives appear, 1 per partition.)
