Samsung 990 EVO Plus 4TB vs Team Group T-Force G70 Pro 4TB SSD

Both are 4TB PCIe 4.0 M.2 drives that hit similar sequential speeds, so the choice comes down to endurance, DRAM and support. The Samsung 990 EVO Plus has a stronger track record: thousands of ratings, a well-known Magician app and Samsung's firmware support, and owners call it fast and reliable. The Team Group G70 PRO adds a DRAM cache, a graphene heatsink and a higher rated endurance, which suits heavy sustained writes and PS5 use. Buy Samsung for proven reliability and software; buy Team Group for endurance and cooling.

  • Choose the Samsung 990 EVO Plus if you want a proven drive with mature software, wide owner feedback and simple drop-in installation for gaming or creative work.
  • Choose the Team Group G70 PRO if you write large files often, want a DRAM cache and a heatsink, or need a drive rated for a PlayStation 5.

What reviewers say

Samsung 990 EVO Plus 4TB

  • 4.9 / 5386 ratings

Owners and reviewers rate the 990 EVO Plus very highly, calling it fast, cool-running and dependable for everyday use. Most praise comes from gamers and creators who moved from older SATA or Gen3 drives. Criticism centres on the lack of DRAM and on write speeds dropping during very large transfers.

What people mention
  • SpeedPraisedOwners say boot times, game loads and file copies feel much quicker than the SATA or Gen3 drives they replaced.
  • HeatPraisedReviewers note it runs cool and efficient, so it rarely needs a heatsink in a desktop.
  • DRAMCriticisedBuyers point out it has no dedicated DRAM cache and relies on host memory buffer instead.
  • Sustained writesCriticisedVery large transfers slow down once the SLC cache is full, which matters for heavy video work.

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.
Reviews
  • Fast and reliable

Questions and answers

Which is better for gaming?
Both load games at similar speeds on PCIe 4.0. The Samsung has the longer track record with gamers and the Magician app; the Team Group runs cooler under sustained load thanks to its heatsink.
Which lasts longer?
The Team Group is rated for 2,960 TBW against 2,400 TBW on the Samsung, so it tolerates more total writes. Real-world lifespan also depends on heat and workload, and both carry multi-year warranties.
Is the Team Group worth stepping up to?
If you move large files often or use a PS5, yes: the DRAM cache, heatsink and higher endurance are real gains. If you want proven reliability and better software, stay with the Samsung.
Does the Samsung need a heatsink?
Not for normal desktop and laptop use; it runs efficiently at Gen4 speeds. In a PS5 or a cramped case with heavy sustained writes, add a third-party heatsink.
Will either fit a laptop?
Both are M.2 2280, so they fit most modern laptops. The Team Group's heatsink makes it thicker, so check clearance before installing it in a thin laptop.
Do both work in a PCIe 5.0 slot?
Yes, both are backward and forward compatible and will run at Gen4 speed in a Gen5 slot. You won't get Gen5 bandwidth from either drive.
