The Orico J-20 is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 512 GB variant. With the rest of the system, the Orico J-20 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the RTS5772DL from Realtek, a DRAM cache is not available. Orico has installed 144-layer QLC NAND flash on the J-20, the flash chips are made by Intel. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 125 GB. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The J-20 is rated for sequential read speeds of up to 5,000 MB/s and 4,700 MB/s write.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Orico guarantees an endurance rating of 150 TBW, a relatively low value compared to other SSDs.
