M4 Mac mini Teardown - UPGRADABLE Storage, Powerful, and TINY

[@hrznn]

As others have said, the SSDs aren't sold separately, BUT people are already soldering larger NANDs onto them, so I expect Aliexpress to sell cheap high capacity SSDs in the near future, as well as local repair shops maybe offering similar services. And harvesting these modules from broken Mac Minis will be a big business as well.

[@mingm]

i dont think so, m1 mac studio also has removable SSD and has been around since 2022. there's still no 3rd party SSD modules available. you still need to treat those as they were soldered ssd

[@MariusVirgilConstantin]

@@mingm Mac Studio is more expensive and it was no demand for 3rd party SSD like the demand that this little Mac mini will have for just 600 dollars.

I prefer to look at it a different way. If you buy the base model, you're letting everyone who pays for one or more of the $200 upgrades pay the Apple tax for you!

[@rdyt0]

​@@EnglishMike Buying 2x base models(16G+256G) is actually cheaper than buying 1x upgraded model with twice the RAM and SSD, 32G+512G). This would be considered tax evasion from your perspective, right?

[@El.Duder-ino]

Beautifully teared down, thx iFixit👍Apple should make these M.2-like modular storage modules swappable and widely accessible for the future upgrade and also not crazy expensive! SoC and RAM r soldered in and very little can be done with that due to performance benefits, however SSD storage should be fully upgradeable.

[@EnglishMike]

They should, but we all know they won't.

[@fritzp9916]

They could and should just use standard M.2 drives, but they won't because their pricing depends on the storage not being replaceable by a 3rd party SSD.

[@PaoYong]

Upgradeability aside the engineering of this thing is pretty beautiful. Not a little bit of space wasted.

[@thecanmanification]

So many people not understanding why the ssd change is a genuine improvement for repairability. The fact that it’s not soldered directly to the board and the memory controller is now on its own daughterboard means that if either component breaks it’s a much cheaper/easier repair than it was before.

[@pinkysweets]

almost nothing changes, apple does not sell replacement, you still need to solder new BLANK nand chip onto that board, and that board has drm. the only thing changed is doing soldering work on that removable board is easier than the main board

[@bmiller949]

Thanks for showing the ease of changing the CMOS battery. The other items are above my paygrade and I will pay someone else to swap out.

The holy grail, if there's room, would be an adapter card you can plug a regular NVME drive into (even if it's has to be a small one). I suspect that could be difficult since the controller chip is on the motherboard, but ingenuity might find a way.

[@CinematicFour]

The first mistake for a mini owner is to buy a unit and upgrade it. Mini are very flexible in how they use resources, even non upgradeable parts.

[@ennis_w]

I think replaceable storage units are also easier for Apple to assemble and reassemble them. Because I saw a lot of ridiculous configurations in Apple refurbished store, such as 8GB + 2TB.

[@RichardServello]

Also, no glue or expensive special tools needed to repair. I remember when I swapped the HDD from my 2010 Mac mini with an SSD and I needed a few special tools (one was literally to lift the motherboard out of the case) and they were VERY expensive.

[@larssandvik1347]

I’ve owned every generation of Mac mini and I love these devices but up until now you’ve always had to buy them exactly the way you wanted to own them their entire life cycle. Hopefully somebody will release the storage module for sale. This will definitely send a message to Apple for them to start making user upgradable products when somebody else is making money businesses usually listen

[@MaxOakland]

It's great to see upgradability return to Macs. Should be the RAM next. Otherwise we need government regulation

[@antonio.zanella]

Apple has been recommended by the EU to make its devices more repairable. In my opinion, in a few years, when the Mini M4 will be at the end of its life cycle, Apple will turn a blind eye if a third party builds a compatible SSD module for the mini M4, not before. However, for the next few years it will be obliged to provide original spare parts, unfortunately for us at a high price.

[@its_argho]

256gb is criminal as of today. This isn’t your phone where you install a couple of apps that take up few megabytes. This is a computer that is meant to run desktop softwares. Softwares that are literally gigabytes in size. To top that off, Mac OS itself and Apple Intelligence language models will be saved on it. You will only have about 150-180GB of usable space. Install maybe 6-7 softwares, store your photos and videos and suddenly you have a low memory warning. Not to mention that if you fill up your storage >90% it’s only a matter of time before the NAND starts corrupting itself. And suddenly all your data is gone.

[@whatever8282828]
