The Neo Forza NFP455 is a solid-state drive in the M.2 2280 form factor, launched in 2021. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Neo Forza NFP455 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the IG5236 (Rainier) from InnoGrit, a DRAM cache chip is available. Neo Forza has installed 128-layer TLC NAND flash on the NFP455, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 313 GB, once it is full, writes complete at 1200 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 NFP455 is rated for sequential read speeds of up to 7,400 MB/s and 5,300 MB/s write; random IO reaches 450K IOPS for read and 900K for writes.
At its launch, the SSD was priced at 130 USD. The warranty length is set to five years, which is an excellent warranty period. Neo Forza guarantees an endurance rating of 900 TBW, a typical value for consumer SSDs.
