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 1 TB 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 processed more quickly. The cache is sized at 250 GB. Copying data out of the SLC cache (folding) completes at 150 MB/s. 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 300 TBW, a relatively low value compared to other SSDs.
