Pros & Cons

Pros

✓ M.2 2230 form factor drops straight into Steam Deck, ROG Ally, and 2230-slot laptops
✓ 5000 MB/s sequential read on PCIe Gen4x4, with 3200 MB/s writes
✓ 5-year limited warranty from Addlink
✓ Backwards compatible with Gen3x4 slots, so older laptops still work

Cons

✗ 2.15mm max height can foul tight 2230 bays with thick thermal pads
✗ DRAM-less design leans on HMB, so speeds drop on hosts without HMB support
✗ Compatibility is only listed for select Steam Deck and ROG Ally models
✗ Thermal throttling kicks in under sustained writes in cramped handheld chassis
