SATA vs NVMe: what your laptop accepts
There are three common laptop SSD types. A 2.5" SATA SSD fits the old hard-disk bay. An M.2 SATA SSD fits a small M.2 slot but runs at SATA speed. An M.2 NVMe SSD fits an M.2 slot and is several times faster. The M.2 types look alike but depend on the slot’s key and protocol, so confirm what your laptop supports before buying.
- 2.5" bay → SATA SSD
- M.2 slot → M.2 SATA or NVMe
- Check M.2 key (B/M) + protocol
- NVMe needs slot + BIOS support
