The Digma Top G3 is a solid-state drive in the M.2 2280 form factor. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Digma Top G3 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the IG5236 (Rainier) from InnoGrit, a DRAM cache chip is available. Digma has installed 128-layer TLC NAND flash on the Top G3, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Top G3 is rated for sequential read speeds of up to 7,400 MB/s and 5,500 MB/s write; random IO reaches 330K IOPS for read and 560K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Digma guarantees an endurance rating of 2000 TBW, a high value.

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
