An SSD can speed up boot times, reduce load times and ease file transfers. Choosing between an NVMe internal SSD and an external SSD mainly depends on possible installation and the mobility you want.
Internal NVMe SSD
An M.2 NVMe SSD plugs directly into a compatible slot in the computer. This can offer very fast connectivity and a clean integration, but you must check the form factor, interface, available space and motherboard or laptop compatibility.
Installation may also require backup, system migration or reinstallation. If you’re unsure about the procedure, first document the exact computer model.
External SSD
An external SSD connects by cable and can be used with multiple computers. It’s suitable for backups, transporting projects and expanding capacity without opening the machine. Its real-world performance depends on the SSD, the enclosure, the cable and the port used.
An external 2.5″ enclosure also lets you reuse an old SATA SSD or hard drive. This solution won’t necessarily match an internal NVMe’s performance, but it can give new life to an available component.
What capacity to plan for?
Documents and office work can get by with modest capacity. Photos, videos, games and project libraries require more space. Avoid filling an SSD completely: keep headroom for updates, temporary files and internal storage management.
Commerce Meritium offers a Netac NVMe M.2 SSD in multiple capacities and a USB enclosure for 2.5″ drives. Compare capacities and interfaces with the device you’ll use.
Upgrading internal storage often means reseating the cooling system too — see our guide on thermal paste vs thermal pad.
Quick decision: Choose an internal NVMe for integrated upgrades and an external SSD for mobility, backups or reusing an existing drive.
