The Colorful CN700 is a solid-state drive in the M.2 2280 form factor, launched on October 31st, 2022. It is available in capacities ranging from 512 GB to 1 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Colorful CN700 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the MAP1602A Falcon Lite from MaxioTech, a DRAM cache is not available. Colorful has installed 128-layer TLC NAND flash on the CN700, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The CN700 is rated for sequential read speeds of up to 5,000 MB/s and 4,500 MB/s write.
The SSD's price at launch is unknown. The TBW rating for the Colorful CN700 1 TB is unknown, too.

YMTC 128L Xtacking 2.0 cell architecture consists of two decks connected through deck-interface buffer layer which is the same process with KIOXIA 112L BiCS 3D NAND structure. Cell size, CSL pitch, and 9-hole VC layouts keep the same design and dimension (horizontal/vertical WL and BL pitches) with previous 64L Xtacking 1.0 cell. Total number of gates is 141 (141T) including selectors and dummy WLs for the TLC operation.
This layout has a 1x 4 Plane layout, each one lineup side by side
