The XPG Gammix S70 Blade is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the XPG Gammix S70 Blade interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the IG5236 (Rainier) from InnoGrit, a DRAM cache chip is available. XPG has installed 128-layer TLC NAND flash on the Gammix S70 Blade, the flash chips are made by YMTC. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. 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 Gammix S70 Blade is rated for sequential read speeds of up to 7,400 MB/s and 6,800 MB/s write; random IOPS reach up to 750K for reads and 750K for writes.
At its launch, the SSD was priced at 300 USD. The warranty length is set to five years, which is an excellent warranty period. XPG guarantees an endurance rating of 1480 TBW, a typical value for consumer 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
