# Team Group T-Force Cardea Zero Z440 1TB NVMe Review (2026)

The Team Group T-Force Cardea Zero Z440 1TB is a PCIe 4.0 NVMe SSD that combines Phison E16 performance with a slim graphene copper foil cooler and 3,000 TBW endurance — a drive built to fit where bulkier Gen4 SSDs cannot.

Quick answer: The Cardea Zero Z440 1TB is one of the most practical first-generation PCIe 4.0 SSDs available. The graphene foil cooling and slim profile solve a real problem — fitting under existing motherboard heatsinks — without sacrificing E16 performance. The 3,000 TBW endurance and 5-year warranty provide long-term confidence. The E16 platform is now a generation behind the E18 and newer controllers, so builders prioritizing raw speed should consider the Samsung 980 Pro or Sabrent Rocket 4 Plus. For users who value practical compatibility, strong endurance, and solid Gen4 performance at 1TB, the Z440 is a well-designed choice.

## Performance

The Z440 1TB delivers 5,000 MB/s sequential read and 4,400 MB/s sequential write — the E16 controller's ceiling. PCMag's independent testing confirmed these figures in CrystalDiskMark, finding the Z440 competitive with or slightly ahead of the Corsair MP600 and Seagate FireCuda 520 in several benchmarks. The drive set the pace for 4K random read speeds among the PCIe 4.0 drives PCMag had tested at the time.

In PCMark 10 real-world storage tests, the Z440 posted strong scores for Windows boot, game loading, and file copies. It tied or topped its PCIe 4.0 competitors in ISO and JPEG copy tests. The SLC cache at 1TB is roughly 333 GB (one-third of usable capacity), providing generous burst write headroom. Post-cache sustained writes settle to approximately 1,500 MB/s. The graphene foil keeps the controller below 80 degrees Celsius under load, which is adequate but not as effective as the C440's ceramic spreader or a dedicated aluminum heatsink.

## Endurance, TBW & Warranty

The 1TB model carries a 3,000 TBW endurance rating with a 5-year warranty. At 50 GB of writes per day, this translates to roughly 164 years. The MTBF is rated at 1.7 million hours. The 3,000 TBW figure is generous for a consumer drive and reflects the endurance characteristics of the Kioxia 96L TLC flash. Team Group offers a SMART Tool utility for S.M.A.R.T. data monitoring and benchmarking, though it lacks cloning and migration features found in Samsung Magician or Sabrent's toolkit.

## Pros and Cons

**Pros:**

- 5,000 MB/s read, 4,400 MB/s write on PCIe 4.0
- Graphene foil fits under motherboard heatsinks
- 3,000 TBW endurance with 5-year warranty
- Strong PCMark 10 real-world scores
- 1 TB capacity fits OS plus game library
**Cons:**

- E16 surpassed by E18 generation in speed
- Double-sided PCB limits laptop compatibility
- No management software available
- Graphene foil less effective than dedicated heatsinks


## Verdict

The Cardea Zero Z440 1TB is one of the most practical first-generation PCIe 4.0 SSDs available. The graphene foil cooling and slim profile solve a real problem — fitting under existing motherboard heatsinks — without sacrificing E16 performance. The 3,000 TBW endurance and 5-year warranty provide long-term confidence. The E16 platform is now a generation behind the E18 and newer controllers, so builders prioritizing raw speed should consider the Samsung 980 Pro or Sabrent Rocket 4 Plus.

## Frequently Asked Questions

### Is the Team Group Cardea Zero Z440 1TB good for gaming?

Yes. PCMag's testing found the Z440 1TB topping its PCIe 40 comparison set in game loading benchmarks, tied with the Seagate FireCuda 520. The 5,000 MB/s read speed and strong 4K random performance translate to fast game loads and system responsiveness. The 1TB capacity holds the OS plus 8 to 15 modern AAA games. The graphene foil keeps temperatures manageable during extended sessions.

### What is the TBW endurance of the Cardea Zero Z440 1TB?

The Z440 1TB is rated for 3,000 TBW (terabytes written) with a 5-year warranty. At 50 GB of writes per day — a heavy consumer workload — the drive would take roughly 164 years to exhaust its rated endurance. This is higher than most newer E18-based 1TB drives, which typically offer 600 to 700 TBW.

### Is the Z440 1TB compatible with PS5?

The drive meets the PS5's PCIe 4.0 x4 NVMe requirement. The 5,000 MB/s read speed is slightly below Sony's 5,550 MB/s recommendation but above the minimum practical threshold. The graphene foil is thin enough to fit under the PS5's M.2 cover. The 1TB capacity holds roughly 10 to 15 PS5 games. Sony does not officially list this model, but it meets the published hardware requirements.

### Does the Z440 need a heatsink?

The drive includes a thin graphene copper foil heat spreader that provides basic thermal management. For typical gaming and desktop use, this is sufficient when combined with a motherboard M.2 heatsink. For sustained heavy write workloads (video editing scratch disks, large file transfers), additional cooling is recommended. The foil alone may not prevent throttling during multi-hundred-GB continuous writes.

### How does the Z440 compare to the Corsair MP600?

Both use the Phison E16 controller and deliver similar rated performance of 5,000/4,400 MB/s. The Z440 uses a thin graphene foil while the MP600 ships with a bulky aluminum heatsink. The Z440 fits under motherboard heatsinks; the MP600 may need its heatsink removed for the same clearance. In PCMag's benchmarks, the Z440 slightly outperformed the MP600 in game loading and copy tests, though the differences were within margin of error.

### Is the Z440 good for video editing?

For light to moderate video editing, yes. The 4,400 MB/s write speed handles 4K preview files comfortably within the SLC cache. Once the cache fills after roughly 333 GB of sustained writes, speed drops to around 1,500 MB/s, which still exceeds the bandwidth needs of most editing codecs. The 3,000 TBW endurance is generous for write-heavy editing workflows. For heavy 8K or multi-stream 4K work, a newer E18-based drive with higher sustained writes would be more appropriate.
