The Teamgroup T-Force Z540 is a solid-state drive in the M.2 2280 form factor, launched on February 23rd, 2023. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Teamgroup T-Force Z540 interfaces using a PCI-Express 5.0 x4 connection. The SSD controller is the PS5026-E26 from Phison, a DRAM cache chip is available. Teamgroup has installed 232-layer TLC NAND flash on the T-Force Z540, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 210 GB, once it is full, writes complete at 3697 MB/s. Copying data out of the SLC cache (folding) completes at 1800 MB/s. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent. The T-Force Z540 is rated for sequential read speeds of up to 12,400 MB/s and 11,800 MB/s write; random IO reaches 1400K IOPS for read and 1400K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Teamgroup guarantees an endurance rating of 1400 TBW, a typical value for consumer SSDs.
