As far as I know, the 2015 Retina MacBook is the only Mac supplied by
Apple to date with an SSD that is soldered to the logic board. All
others are socketed.
In recent models, Apple has been using proprietary connectors based on
PCIe. Based on OWC's product listings, it appears that the variants are:
1. MacBook Air (Late 2010 to Mid 2011)
2. MacBook Air (Mid 2012)
3. MacBook Pro (Mid 2012 to Early 2013)
4. MacBook Air (Mid 2013 to Early 2015) and MacBook Pro (Late 2013 to
Mid 2015)
5. iMac (Late 2012 to Early 2013)
6. Mac Pro (Late 2013)
I don't know offhand if they vary in terms of connector compatibility,
or just in form factor.
OWC has no SSD options for 2013 and later iMacs, nor do they mention
PCIe SSD module upgrades for Mac Minis, only SATA.
Apple may in fact be using common modules around similar timeframes
(e.g. in Mid to Late 2012 models), which would simplify management of
components, but OWC just markets them as being for different families to
minimise potential confusion.

The SSD is a part which has a limited lifespan that might need to be
replaced within the five to seven year official support window (plus
however many months that model was available, for those bought early
rather than late).
Apple doesn't offer SSD upgrades, but they can replace faulty ones
(presumably for an exorbitant fee, if AppleCare has lapsed).
