An NVMe enclosure lets you use spare M.2 SSDs as external storage. Cheaper than pre-built external SSDs but requires assembly.
Enclosure + SSD combo vs pre-built external SSD: cost comparison
**DIY route**: Enclosure ($20–40) + 1TB NVMe SSD ($70–100) = $90–140 total.
**Pre-built (Samsung T7)**: $150–180 for same capacity.
Saving: $40–90 by DIY. Trade-off: Requires assembly (2 min, very easy).
**USB 3.1 (10 Gbps)**: $20–30, good for NVMe (which max at 1,000 MB/s = 8 Gbps).
**USB 3.2 (20 Gbps)**: $30–50, overkill, future-proof.
**Thunderbolt**: $80+, overkill for SSDs, mainly for video.
Key enclosure features: passive cooling, M-key support
**Passive cooling**: Aluminum or copper design (no fan). Important for long transfers — NVMe throttles if hot.
**M-key support**: Standard M.2 NVMe slot. Avoid B-key only (SATA, not NVMe).
Best budget enclosure: Anker NVMe Enclosure (~$20)
Compact, USB 3.1, aluminum passive cooling. Reliable, most popular budget pick. Add any 1TB SSD for total $90–120.
