Yes, with your current SATA SSD it would drop your boot time to under 20 seconds. The 2014 mini has an internal port for an even faster PCIe SSD. That is why 2014 Fusion Drive minis have great storage performance.

Both types of SSD are somewhat challenging* to install.

*This recalls your impulse that "I am gonna have to ditch the 2014 model for a 2012...". You may choose to replace that mini with a 2012 or more potent 2014 after weighing the cost, effort, and risks involved with an internal storage upgrade against the basic limitations of a 2012 base model mini. Regardless of what you do to that mini you will always be limited to 4GB of RAM and a CPU clock rate that is a bit over half as fast as the 2012s and other 2014s. Because the 2012 minis have upgradeable RAM and the 8GB available in the other 2014 minis is enough for most tasks you need to consider these factors and others.

Are you good at tinkering with compact or delicate electronics? Experience with laptop repairs would help as would the videos, text info, and tools from iFixit and others.

How do you plan to use this mini? Eight really is enough for most folks most of the time. Upgrading my 2012 mini RAM from 4GB to 8GB provided a real improvement but the next step to 16GB was more subtle. With the RAM maxed out Activity Monitor stats like Memory Pressure reveal that this Mac is never short of RAM but it is hard to pinpoint specific performance improvements.

I wonder what sort of bootstrap times others experience with similar setups?

Seems like we are covering the same ground again. As I posted above, I get a 30 second boot time on Sierra with an external Samsung T3 500gb SSD on a 2012 2.5ghz i5 Mini with 16gb RAM. My 2012 i7 2.6 ghz 16gb quad Mini boots MacOSX 8.5 in 14 seconds from the original internal Apple 256gb SSD.

My 2014 base mini seems like it takes about a half hour to boot from the original 500gb hard drive. :p

Boyd01 is right! The posted information already indicates that your 48 second boot time is right on target for your mini equipped with a slower CPU and ¼ of the memory of his 2012. In other words, tuning probably won't shorten this boot time so you have a choice to make.

OP, think about your use case. Mine - Have a 2011 I5 mid-spec with AMD 6630M....a ticking time bomb. But after all these years it still works great, so I repasted and we'll see. I recently bought a 2012 2.3 Quad, added a second drive, and this is my iTunes and Plex server. 16gb RAM, 256gb SSD + 2tb Firecuda drive and quad for Handbrake. This machine is online 24/7 but at boot it takes seconds. What is really important to you?
 
I got myself late 2012, 2.3, i7, 8gb, I will be installing Samsung 120gb SSD. Should I keep 1TB along with SSD or replace with 120gb SSD? I want to upgrade the ram to 16GB. Can someone tell where to get good priced 16 ram? Also can someone point me to a video that has good instructions on upgrading SSD.
 
Samsung SSD installed removed 1TB hard drive and put it USB external case.

Need to find two 8GB ram cards, Canadian store.
 
Do I need to enable TRIM? If so, can you please provide a URL with steps.
 
Enable, Disable TRIM through Terminal under Sierra OS
Launch launch Terminal (Found in /Applications/Utilities/), then enter the following command line.

sudo trimforce enable
You then will be asked to confirm your action with your administrator password.

Similarly, use the following string to disable TRIM

sudo trimforce disable
Note: The mac need to be rebooted to complete the process.

Why Disable?
 
Stopwatch started a soon as I hit power until I saw Desktop

2014-1.4ghz,4gb,i5,external ssd took 48sec to boot

2012-2.3ghz,8gb,i7,internal ssd took 25sec to boot

I will be upgrading 2012 Mac Mini ram from 8gb to 16gb

I didn't know external ssds were slower

I get 14 seconds with the original Apple 256gb ssd, which is my only internal drive. Try running the Blackmagic disk test and see how fast your SSD is. This is what I get. But really, does it matter? Why the fixation on boot times? :)

I recently added SSDs to two late 2012 Mac minis. My advice is: 1) Watch the OWC videos. The static PDFs make the process look terrifying. The videos just make it look moderately challenging. 2) Go very slowly. If a step in the video looks confusing once you have your mini open, watch it again and again until it's clear. Take as much time as you need. 3) No matter how tight a connector is, and no matter how frustrated you become, resist the temptation to apply more force. Just keep gently wiggling and pulling. Eventually, it will come loose.

Where can I find a Mac Mini Late 2012, prefer i7, 2.6, 16gb. I have a ssd that I can use. I want to replace my late 2014 with late 2012.


Glad I Held onto mine, I have a 2012 i7 server that came with 2 1tb hdd's installed. I added 16 gigs of ram and exchanged the two drives for ssd's. It boots in under 10 seconds. Never seems slow. Its been running nonstop for almost 5 years without a hiccup. I feel like I could easily get another 5 years out of if.
