WD SN530 256GB NVMe SSD vs WD Green SN3000 2TB NVMe SSD
Buy the SN3000 2TB if you have a standard M.2 2280 slot and want far more space and speed: 2TB versus 256GB, PCIe Gen4 with 5,000 MB/s reads versus Gen3 at about 2,400 MB/s. Buy the SN530 256GB only if your device takes the short M.2 2230 card, such as a Steam Deck, Surface or compact ultrabook.

Questions and answers
- Which is better for a Steam Deck or handheld?
- The SN530. Handhelds use the short M.2 2230 slot, and the SN3000's 2280 length will not fit. The trade-off is 256GB of storage.
- Which is better for a gaming desktop?
- The SN3000 2TB. It gives eight times the capacity and roughly double the read speed, and a desktop 2280 slot takes it directly.
- Is the SN3000 worth it over the SN530?
- For most 2280-slot buyers, yes. You get 2TB instead of 256GB and Gen4 speed. Check both live prices on this page, since no prices were provided.
- Which lasts longer?
- The SN3000 has far more capacity, so its total bytes written rating is much higher. The SN530's TLC NAND and 256MB cache help, but 256GB wears out sooner under heavy writes.
- Can I put the SN530 in a desktop?
- Only if the board has an M.2 2230 mounting point or you use a 2230-to-2280 adapter. Most desktops expect a 2280 card like the SN3000.
- Do either need a heatsink?
- The SN530 runs cool at 75 mW active and does not need one. The SN3000 runs faster and warmer, so a heatsink helps in a desktop or under sustained writes.
