If the SSD is user expandable, then its damn near perfect, but I get the feeling they pointed out the DIMM and not the SSD as replaceable.

- wmf 8y agoBecause of the way the T2 works, storage will never be replaceable/expandable in those Macs.
- mcphage 8y agoHow so?
- mcrute 8y agoNormally an SSD has an on-board flash controller that communicates something like NVME or SATA to the host and a protocol like CFI to the actual NAND chips, it will also map from disk blocks (OS unit of storage) to NAND columns and cells using an internally stored table. These chips do a lot of other mundane things like wear leveling for NAND, clearing written cells, etc. If the T2 is taking the place of this controller and communicating directly with the NAND chips it would be at best duplicative of an external SSD controller and at worst completely incompatible.
- mcphage 8y agoThanks :-)

- mcrute 8y agoBased on the marketing photos on the Apple site it sure looks like the NAND is soldered to the board and not socketed.
- jamesfmilne 8y agoAlas no, it's basically soldered on. I'd love it with a pair of M.2 NVMe slots, but no such luck! I'd advise getting the smallest flash drive option then just use an external NVMe drive via Thunderbolt. At least you can upgrade that.
