Mac mini M4 2TB SSD Hard Disk Upgrade DIY

October 2025 update: Still very happy with my choice. It's been working fine for months now with no issues. I would definitely buy from this company again. Works great, and still going strong after a month. Following iFixit and other YouTubers' instructions worked well for me. No problems getting into the case, but I did have the help of an iFixit kit that includes spudgers and guitar picks to pop the bottom shell open. Once you get past that (without any scrape marks!), it's pretty easy. I did not need to pull away any of the connectors, like some people do with the power switch. That little connector is very fragile, and does not pull away laterally the way most people would think it works. It needs a gentle upward tug. When you put it back on again, press down from above, and don't try to slide it in. I watched one YT'er break his on camera because he pulled in the wrong direction, so be very careful if you decide to remove yours. I'm extremely pleased with the extra speeds I'm getting, and very, very pleased with my new 2TB Mini!

Working solid for 5+ months. Planning to buy another soon. Initial installation appeared faulty, however, all was fine after verifying electrical contact between main circuit board and disk circuit board. I suspect the contacts may be compromised if the disk circuit board mounting screw is too tight or too loose. We invested in a torque driver to set the Torx Plus 8IP screw to 0.65 Nm per Apple instructions.

Was excited to beat the egregious Apple storage upgrade tax. Tried several times with multiple Macs, USB-C cables, even different firmware versions. DFU failed every time. Error code 21 is a hardware failure. The Mac works fine with the stock SSD. I'll try again, because I am an expert at taking apart the Mac Mini M4 at this point. I wanted to request an exchange but the automated system only let me do a return. UPDATE: I did buy another SSD upgrade from another vendor on Amazon, and it’s working fine. Fired up on the first attempt. I think these just might have a high failure rate and minimal testing/QC by the vendors, so if you don’t have the patience to try a couple times, this project could be frustrating.

Why did you pick this product vs others?: I was nervous about installing this, and there were some issues during the install. It took me a few tries before I found a thunderbolt 4 cable to update the firmware from my other Mac. Failed 3 times before I made the switch. But once I had the right cable it updated flawlessly. My New 2TB SSD is faster than the original and has more storage space than I need. Maybe not for the faint of heart, but this is an incredible value! Watch several of the YouTube videos and make sure you follow the instructions carefully!

This is a good value and high performance SSD replacement for my Mac MINI M4. For some reason, the first SSD I receive did not work after running DFU. It kept showing an error and even if I tried to re-run the DFU process, it failed for at least 5 attempts. I've done this process a few times before so I'm pretty sure it was not user error. It appeared the first SSD I received was a lemon. However, once I contacted Amazon, the agent was able to ship me the replacement overnight (again), and the 2nd SSD I got worked instantaneously. In summary, this purchase was a a sound investment to upgrade your M4's storage. However, be sure that you follow the installation steps (from You Tube) carefully. Also, there is NO need to remove the power ribbon cable nor the fan cable at all. You just need to be cautious when you lift up the lid. I highly recommend this SSD for anyone who owns a Mac Mini M4. I got a lemon (DOA) initially, and had to wait for the replacement. Hence I remove 1 star but the replacement worked flawlessly. This is something to keep in mind.

I was afraid the chip may not work as its a brand new kit for installation on a now replaceable drive for macs. However, after watching some howtos, and selecting what I believed to be a better option to purchase from the others, I'm glad I got this one. I have had my mini m4 running nonstop for several months and its working without a problem. Updates are no issues for mac os updates and read/write speed are fantastic for video edits upto simple 8k edits according to my blackmagic disk speed test. I've only done upto bmpcc 6k videos and its working as it should.

Don't waste money by paying Apple for their overprice storage!! This kit is easy and way more affordable way to max out your M4 Mac Mini storage option. Take your time and watch a couple tutorials. I would say almost anyone can install this kit. The build quality also appeared to be pretty decent. The read/write speeds are also an improvement over the standard 256GB that my M4 came with.

Installed really easy into the Mac mini. M4 works great nice and quick love it.

Montato senza troppi problemi il 16 Giugno, oggi è il 21 Agosto e ancora funziona tutto regolarmente. Sono contento di aver acquistato questo prodotto, ho risparmiato bei soldini, spero duri a lungo.

Works well no issues so far, easy to install. I found the included screwdrivers were no good not quite the right size there was a worry about stripping the screws so I would use alternate drivers.

The setup is a bit ‘nerdy’, but fairly simple and foolproof with the required tools and one of the good how-to videos on YouTube; you also need to have another fairly recent Mac at hand. It takes about an hour and the result is truly spectacular, transforming the cheapest Mac ever (?) into a powerful, fast tool.

Finger weg.

Upgrade is straight forward as long as you do your research and take steps to protect your device during the process. The only issue I had was not using an Apple USB C cable which caused the restore to fail in DFU mode. My Mac now has a 2TB SSD (was 256GB) at a fraction of the price Apple will charge you.
