Apple has made it nearly impossible for users to upgrade their storage and memory after buying a Mac computer, so whatever configuration you get at the time, you'll need to use it for the rest of its life. However, there are other ways to increase the existing storage space on these machines, and one modder showed how he went the extra mile to increase the flash memory of the latest M3 Max MacBook Pro to 8x the original configuration.
The latest M3 Max MacBook Pro in Liplippsi's hands comes with 1TB of storage, and while most users will find this sufficient, others will find it completely limited. It's also disappointing that Apple is charging a ridiculous premium for upgrading 512GB of RAM to 1TB, so modders have come up with an "easy" way to increase memory. Unfortunately, this task is difficult for the average user of the MacBook Pro, as it requires some soldering tools, a steady hand, and a sophisticated understanding of the internal structure of the MacBook Pro.
As you can see, the M3 Max MacBook Pro has some empty solder joints on it that can be used to mount flash memory, and in the next image, we see that some NAND chips have filled this particular area. The exact storage capacity is not mentioned in the article, but assuming that this MacBook Pro comes with 1TB of storage, then in order to upgrade to 8TB, the existing flash memory may have to be removed, so 4 memory chips means that each NAND flash memory will have 2TB of storage.
Still, soldering some storage exactly to the M3 Max MacBook Pro doesn't mean the machine can boot up right away, as macOS is already pre-configured to recognize that the product has 1TB of internal storage. Therefore, some software tweaks are required before the operating system recognizes the memory upgrade, although for some reason the modeler does not show this step in the image.
The M3 Max MacBook Pro's upgrade path also doesn't detail the 8TB flash drive**, but it's easy to assume that it will be very affordable compared to what Apple charges customers. Unfortunately, Apple doesn't seem to change its stance on upgrading its machines, so you'll either have to pay an "extra tax" to the Cupertino giant or find someone with enough skills and the necessary hardware to make it happen.
