Questions and answers
- Which is better for a Steam Deck?
- The Crucial P310. It comes in M.2 2230, the size the Steam Deck takes, and the SN7100 is 2280 only.
- Which lasts longer?
- The SN7100, at 600 TBW. The P310 is listed with a low TBW rating, so it wears out sooner under heavy writes.
- Is the SN7100 worth the extra over the P310?
- If you have a 2280 slot, yes for capacity and endurance. If you need 2230, the SN7100 will not fit at any price.
- Which is faster?
- The SN7100 on paper: 7,250 MB/s read and 6,900 MB/s write versus 7,100 and 6,000. Real-world game load times will be close.
- Do either have DRAM?
- No. Both are DRAM-less, so both rely on host memory buffering and can slow on long sustained writes.
- Can I put the P310 in a PS5?
- The listing says it works with PS5 and PS5 Pro. It has no heatsink, so add one for the console's slot.
