Team Group T-Force G70 Pro 4TB SSD vs WD Black SN850X 4TB NVMe SSD

The WD Black SN850X is the safer pick for most people: a well-known controller, a long track record, and strong owner ratings. The Team Group G70 Pro matches or beats it on paper with slightly higher read speed, a graphene heatsink and a huge 2,960 TBW endurance rating. Build quality is close on both, but the SN850X has more independent testing behind it. Buy the Team Group if you want the heatsink included and the higher endurance figure; buy the WD if you want the proven name.

  • Choose the Team Group G70 Pro if you want a heatsink in the box, the higher rated endurance, and top-end Gen4 read speed for a PS5 or a desktop.
  • Choose the WD Black SN850X if you want the drive with the longest independent track record and strong owner ratings, and you can supply your own heatsink.

What reviewers say

Team Group T-Force G70 Pro 4TB SSD

Owners and reviewers treat the G70 Pro as a fast, well-priced Gen4 drive that hits close to its rated speeds and runs cool enough for a PS5. The main reservations are the thin heatsink under sustained load and less confidence in the brand's firmware support than the big names.

What people mention
  • SpeedPraisedReviewers find it close to its rated Gen4 sequential speeds in benchmarks.
  • HeatsinkMixedThe graphene sheet fits PS5 and laptop slots, but some say it is too thin for heavy sustained loads.
  • ThermalsMixedIt runs cool in normal use, though long writes can push temperatures up without airflow.
  • EndurancePraisedThe 2,960 TBW rating is seen as generous for a 4TB consumer drive.

WD Black SN850X 4TB NVMe SSD

  • 4.8 / 591 ratings

Owners rate the SN850X very highly, praising its speed in games and large file transfers and its steady behavior over time. Complaints center on heat under long writes and the lack of a heatsink on this version.

What people mention
  • SpeedPraisedOwners say games and large files load noticeably faster than on older PCIe 3.0 drives.
  • HeatCriticisedSustained writes push temperatures up, and some say a heatsink is needed in desktops.
  • ReliabilityPraised

Questions and answers

Which is better for a PS5?
The Team Group G70 Pro, because it ships with a graphene heatsink and Sony recommends a heatsinked drive. The SN850X without heatsink needs a separate heatsink fitted before use.
Which lasts longer?
The Team Group publishes a 2,960 TBW endurance rating, which is high for 4TB. WD does not publish a comparable figure for this drive in the listed specs, so the Team Group is the clearer claim.
Is the WD worth stepping up to?
If you value a proven controller and a long review record, yes. On raw speed the two are close, and the Team Group is slightly ahead on rated read speed.
Do both need a heatsink?
Only the WD, which is sold without one. The Team Group includes a graphene heatsink, though you can remove it for a laptop slot if clearance is tight.
Are they the same size and fit?
Yes. Both are M.2 2280, PCIe 4.0 x4, NVMe, so they fit the same slots. The Team Group is thicker because of its heatsink.
Which is better for sustained large file writes?
Both have DRAM cache and should hold up well. The Team Group's higher endurance rating suggests it is built for heavier write loads.
