WhatAftermarket M.2-to-Apple-proprietary SSD adapter boards with plug-and-play macOS compatibility, sold as DIY upgrade kits for Mac Studio and Mac Mini users.
SignalCommenters are frustrated that Apple uses proprietary SSD connectors instead of standard M.2, making storage upgrades expensive and locked to Apple's ecosystem despite the hardware technically being modular.
Why NowWith the Mac Pro gone, the Mac Studio becomes Apple's top desktop — meaning far more units in the field needing storage upgrades, and third-party reverse-engineering of Apple's SSD interface has matured enough to ship reliable adapters.
MarketMac Studio and Mac Mini owners needing more storage; millions of units sold. OWC has some kits but availability and compatibility are spotty. ~$300M TAM in Mac storage upgrades.
MoatFirst-mover on reliable, validated adapter designs for each new Apple Silicon generation creates brand trust and repeat purchases in a market where reliability is paramount.
