Mac mini M4 SSD 1TB Hard Disk Upgrade DIY Kit

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!

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

Was not able to DFU and setup on an Apple Mini m4. Received repeated errors when trying to setup. Tried numerous times with different cables and reboots. Returned for refund. Note: Chips on the memory card did not look anything like the photos on Amazon. Chip was from an unknown company called Deep Sea Technology.

Works perfectly and save me so much money over the apple upgrade!

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.

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.

Great product… Very straightforward, had no issues. It was a little bit slower than I would like… But still very close to the stock SSD.
