Kingston NV3 or KC3000? 1 TB SSDs compared
Compare the advertised speeds, write endurance and compatibility of the NV3 1 TB and KC3000 1,024 GB.
Published 1 October 2026 · Source-based comparison
At this capacity, the NV3 and KC3000 differ in advertised write speed and TBW rating. The KC3000's features may be useful for demanding file work; for extra storage alone, purchase price may be the deciding factor.

Product specifications are manufacturer claims. Figures in standards comparisons are not measured real-world results. Conclusions depend on how you use the device.
Capacity changes the speed figures
This table uses figures for the NV3 1 TB and KC3000 1,024 GB. Do not apply the 2 TB model's write speed to a 1 TB model in the same range. The NV3 also comes in different physical sizes; this comparison covers the 2280 version.
TBW is not a failure date
TBW describes the manufacturer's specified amount of data written, not a promise about the date the drive will stop working. Check the warranty's time and write-endurance limits. Both drives still need a backup.
Consider the workload, not just the peak figure
Games, large video projects and sustained writes are different workloads. The table's peak sequential speeds do not measure game loading times or speed after the cache fills. If your work writes a lot of data, also look for independent sustained-performance tests.
Three checks before buying
- Confirm NVMe and M.2 2280 support in your computer's manual.
- Check the exact capacity and product code.
- Consider cooling and the drive thickness your laptop allows.
Frequently asked questions
Will a PCIe 4.0 drive work in a PCIe 3.0 slot?
In a compatible NVMe slot, it may work at the slower connection speed. Check the motherboard or laptop manual.
Does a higher TBW rating make a better backup?
No. A single SSD does not replace a separate backup.
