You are correct on this.
When i finished my installation and booted from external HDD. Under disk utility both the SSD and 1TB hDD were in red. When i tried Disk utility to have them formatted it asked me to fix and i did.
Apple Disk Utility automatically combined them both as 1 Internal Drive.
I wasnt sure if thats how it was but i still went ahead with OWC procedure after it finished and it still showed as 1 Disk.
Under about this MAc and more info, i see Storage as MAss+Flash so its COOL!
You can set it up that way. Some feel it is better to have two separate drives so that if one fails the other is still OK. With Fusion if one fails you lose your data because they are joined at the hip. The speed may be better on the stand alone SSD because it is not writting to HD. As an example you could use the HD as a time machine backup drive for your SSD if your SSD is large enough for your speciifc use. I like having having a large SSD and an external HD for TM backups but that's just me.
1> What is the largest SSD drive (required specs would be appreciated) that you can install in a late 2012 mac mini next to the 1 TB internal HD.
2> I already have tons of programs and files running on the internal HD, I don't want to lose anything adding that SSD. Advice?
3> Fusion or standalone 2 drives? Speed is my primary goal here cause I believe that mac mini with just internal HD in unusable. I can't even run Apple mail program normally.
Thanks a lot for help in advance.
I am running 2 drives in my mid-2011 mac mini server a 240gb ssd & a 1.5TB spinning hard drive.
