Upgraded mac mini HDD to SSD and now it's the speed it should have been

Less of a question. More of a statement, but the statement that I had trouble finding when I was trying to understand why my Mac mini was so slow for the last 3 years.


I have a late 2014 Mac mini - with 8GB RAM and 1TB HDD (5400rpm). Since I bought it, it's run slow. I'd Google what to do to improve it - downloaded lots of software to clean it up and make it run quicker. Nothing worked. The CPU never got busy, and iState menus rarely showed it doing anything but idling, even when I wanted software to open and it was doing nothing.


Eventually I ran a test to see what speed my HDD was being read and written to, and the results were poor. I found one post somewhere that suggested a SSD replacement would make a difference, so I bit the bullet and paid £350 for an Authorised Reseller to replace the 1TB HDD with a 1TB SDD.


From the moment I reinstalled from the Time Machine backups, this Mac mini is now the speed it should have been from day 1. It is blindingly fast now. No longer do I have to wait minutes for it to boot up. No longer do I have to wait minutes for it to open software. It's in the blink of an eye, as fast as my MacBook Pro, which also has an SSD.


So I wanted to state a couple of things:


  1. If you have a slow Mac mini and can't figure out why. Replace the HDD if it's 5400 rpm. Get an SSD, it is like having a new machine.
  2. I don't know why this information isn't more widespread.
  3. I don't know why Apple sold this Mac mini with a disk speed that cripples its performance.


That's all. Hope this helps someone.

Hi again,


I appreciate subjective perceptions of speed are just that, and of course, I would always want a new SSD to be quicker than my old HDD, but here's a piece of data to back up the point.


  • Average boot time before SSD (average of 10 boots) from chimes to log-in screen, was 4 mins 35 seconds.
  • Average boot time after SSD (with Time Machine backup reinstalled on the SSD) = 15 seconds


That's a pretty big improvement. I know it's only one measure, but hopefully it gives an indication that this isn't a marginal difference.


Let's see how things last over time.... :)

Hi - thanks for posting. A few replies back...


  1. The processor is the same as before, yes. But the responsiveness and speed of the overall machine (not just the processor/video card) is dramatically improved.


Before, the processor was running only minimally, even at times when it should have been working hard (e.g. to boot-up or open apps), I guess perhaps the read/write times of the HDD didn't give it enough 'food' to process and spit back out. Now it's up to 75 - 80%. As I say, in terms of the responsiveness and speed of the overall machine (not just the processor/video card) it's dramatically improved.


2 - I now have a 4-5 year old Mac, which is faster and more responsive than it did when it was new and had an HDD. I find it hard to understand why more people don't change the drive now: usually the advice is the bulk up the RAM.


3 - Understood about the price point need. But it was almost unusably slow from the get go.

I know you believe this, but without hard data (such as recording the before/after times) you are relying on your perception of a old and slow Mac compared to a old and slow Mac you want to believe is a lot faster. Think of it in terms of being on the highway, then suddenly entering a 25 MPH zone. In your perception you are traveling a lot slower, but in reality it is merely 30 MPH slower than being on the highway. The reverse is equally true - if you have never traveled above 25 MPH then 55 seems like light speed in your perception.

I find it hard to understand why more people don't change the drive now: usually the advice is the bulk up the RAM.

My advice is always to replace the Mac. There is too much performance to be gained in 5 years to justify only replacing the hard drive. Looking at the GeekBench scores for the latest MacMinis shows them topping out at 28,094. The fastest of the late 2014 MacMinis pegs out at 7,834. That's roughly 3.5 times slower than the 2018 models. An SSD is not going to close that performance gap in any appreciable way that justifies the cost.

So I wanted to point out a few flaws in this posting:


  1. No, it won't be like having a new machine. The processor/video card will still turn in the same Cinebench/GeekBench numbers as before. You *perceive* the Mini is faster, but the processor still handles the same workload as before. The addition of a SSD will not turn a MacBook 2.13 GHz Core 2 Duo into a 4K editing station.
  2. This information isn't more widespread as you still have an old, slow Mac with an arguably faster hard drive.
  3. Apple sold the Mini with a 'slow' hard drive to hit a price point. How quickly we forget SSDs used to be multi-thousand dollar items. I purchased one of the first available 500GB SSDs from Crucial, and paid over a thousand dollars for it. A 1 TB drive - as I recall - was not even available at the time, but if it were the price would have at least doubled.
