The Kingspec XG7000 Pro is a solid-state drive in the M.2 2280 form factor, launched in 2022. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Kingspec XG7000 Pro interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the IG5236 (Rainier) from InnoGrit, a DRAM cache chip is available. Kingspec has installed 128-layer TLC NAND flash on the XG7000 Pro, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The XG7000 Pro is rated for sequential read speeds of up to 7,400 MB/s and 6,600 MB/s write.
At its launch, the SSD was priced at 67 USD. Kingspec guarantees an endurance rating of 1200 TBW, a very low value compared to other SSDs.

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
