Teamgroup T-Force Cardea Zero Z440 1TB SSD Review (PCIe Gen 4)

Rating: 9.0.

Teamgroup may be a name some of you don’t immediately recognise but they have been around for over 20 years. The company’s T-Force product line covers their high-performance and gaming products. The new flagship SSD of the T-Force line-up is the Cardea Zero Z440 SSD, a drive that sports the latest PCIe Gen4 x4 interface.


Teamgroup’s T-Force Cardea Zero Z440 uses a combination of a Phison PS5016-E16 controller (the world’s first PCIe Gen 4 controller) and BiCS4 96-layer 3D TLC NAND. At the time of writing, there are only two drives in the T-Force Cardea Zero Z440 line-up, the 1TB drive we are looking at here and a flagship 2TB model.

The official performance figures are the same for both drives. Up to 5,000 MB/s and 4,400MB/s for Sequential read and write respectively while the 4K random rating is up to a very impressive 750,000 IOPS for both reads and writes.

The official endurance figure for the 1TB drive is 1,800TB TBW and the drive is backed with a 5-year warranty.
