The Teracle T450 is a solid-state drive in the M.2 2280 form factor, launched on January 3rd, 2023. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Teracle T450 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the IG5236 (Rainier) from InnoGrit, a DRAM cache chip is available. Teracle has installed 176-layer TLC NAND flash on the T450, the flash chips are made by SK Hynix. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 666 GB, once it is full, writes complete at 2200 MB/s. Copying data out of the SLC cache (folding) completes at 800 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The T450 is rated for sequential read speeds of up to 7,400 MB/s and 6,400 MB/s write; random IO reaches 1000K IOPS for read and 800K for writes.
At its launch, the SSD was priced at 140 USD. The warranty length is set to five years, which is an excellent warranty period. Teracle guarantees an endurance rating of 1200 TBW, a typical value for consumer SSDs.
