You can’t use a normal M.2 NVMe SSD as an internal replacement. The Mac mini’s internal “SSD module” looks M.2-like, but it doesn’t have a storage controller (the controller is in the Apple silicon), so standard M.2 drives are incompatible for internal upgrades. iFixit[[2]](https://freemwiki.com/index.php?mobileaction=toggle_view_mobile&title=Openai%2F695d12de-8bb4-8008-aa2c-fc8e5d77b9e2#cite_note-2) 2. If you mean “most compatible M.2 SSD to use externally” (in a USB4/Thunderbolt NVMe enclosure), then the SSD model matters less than the enclosure + chipset + cable, and even sleep/wake behavior. macOS TRIM/SMART support varies primarily by connection/bus + interface. The Eclectic Light Company[[3]](https://freemwiki.com/index.php?mobileaction=toggle_view_mobile&title=Openai%2F695d12de-8bb4-8008-aa2c-fc8e5d77b9e2#cite_note-3) And there are reports on macOS 26.2 + Mac mini M4 of USB4/TB external SSD disconnects, often linked to sleep/wake and certain enclosure chipsets (commonly mentioned: ASM2464-based).

For Mac mini M4, a standard M.2 NVMe SSD is only usable externally (USB/Thunderbolt enclosure). You can’t drop a normal M.2 into the Mac mini as an internal replacement. Since you said 10Gbps USB (USB 3.2 Gen 2): ##### What’s “most compatible” at 10Gbps[edit](https://freemwiki.com/index.php?title=Openai/695d12de-8bb4-8008-aa2c-fc8e5d77b9e2&action=edit§ion=9 "Edit section: What’s “most compatible” at 10Gbps") At 10Gbps you’re capped around ~900–1,050 MB/s, so the “best” SSD is the one that’s cool, low-power, and stable (because most real problems are enclosure chipset / sleep / hubs). Also: macOS generally doesn’t give you “full” TRIM/SMART behavior over plain USB the way Thunderbolt does.
