WD Black SN770 NVMe SSD vs Crucial P310 NVMe SSD

The Crucial P310 is the faster drive on paper, with sequential reads up to 7,100MB/s against 5,150MB/s for the WD Black SN770, and it ships with a heatsink and a five-year warranty. The SN770 uses TLC NAND with a proven controller and strong owner ratings, while the P310 uses DRAM-less QLC, which can slow down on sustained large writes. Buy the P310 for a PS5 or a Gen4 desktop where peak speed and cooling matter; buy the SN770 for steady all-around PC gaming and content work.

  • Choose the WD Black SN770 if you want consistent write performance for game installs, large file transfers and everyday PC use, and you value a long track record of good owner reviews.
  • Choose the Crucial P310 if you are filling a PS5 or a Gen4 slot that benefits from a heatsink and the highest sequential read speed.

What reviewers say

WD Black SN770 NVMe SSD

  • 4.6 / 5924 ratings

Owners rate the SN770 highly, calling it a fast, reliable Gen4 drive for the money. Most praise comes from gamers and laptop upgraders who see big load-time drops. Complaints center on sustained write speed and the lack of DRAM.

What people mention
  • SpeedPraisedOwners say games and apps load much faster than on SATA or Gen3 drives.
  • ValuePraisedBuyers call it one of the better price-to-performance Gen4 drives.
  • Sustained writesMixedLarge transfers can slow once the cache fills, though everyday use feels fast.
  • DRAM cacheCriticisedSome owners note the lack of DRAM and hardware encryption versus premium drives.

Crucial P310 NVMe SSD

Reviewers treat the P310 as a solid value Gen4 drive for gaming and general use, with fast reads and easy setup. They warn that its QLC NAND and DRAM-less design make sustained writes and heavy workloads its weak spot.

What people mention
  • SpeedPraisedOwners report quick boot times and fast game loads from the high sequential reads.
  • Sustained writesCriticisedReviewers note write speeds drop once the SLC cache fills on large transfers.
  • EnduranceMixedSome buyers accept the QLC endurance rating for gaming, while heavier users see it as a limit.
  • HeatsinkMixedThe heatsink helps temperatures in desktops and PS5s but can foul tight laptop slots.

Questions and answers

Which is better for a PS5?
The Crucial P310 with the heatsink. Sony requires a heatsink on expanded PS5 storage, and the P310's higher sequential read meets the spec comfortably. The SN770 works too, but you would need to add your own heatsink.
Which lasts longer?
Both carry five-year warranties. The SN770's TLC NAND generally handles heavy sustained writing better over time, while the P310's QLC is fine for game libraries and light writes.
Is the P310 worth stepping up to over the SN770?
Only if you want the higher peak read speed or the included heatsink. For most PC gaming, the SN770's steadier writes and lower heat make it the safer pick.
Does the SN770 fit a laptop?
Yes, in the M.2 2280 size, and the single-sided design helps in thin laptops. The P310 is 2280 only, and the heatsink version is too tall for most laptops.
Will either one slow down when copying big files?
The SN770 is less likely to. The P310's QLC cache can fill during long writes and drop to much lower speeds, which matters for large video or archive transfers.
Do I need a Gen4 slot for these?
Both are PCIe Gen4 drives and work in Gen3 slots at lower speed. You only get the full rated read speeds from a Gen4 M.2 slot.
