The ADATA Ultimate SU650 is a solid-state drive in the 2.5" form factor, launched in 2021. It is only available in the 512 GB capacity listed on this page. With the rest of the system, the ADATA Ultimate SU650 interfaces using a SATA 6 Gbps connection. The SSD controller is the RTS5735DLQ from Realtek, a DRAM cache is not available. ADATA has installed 128-layer TLC NAND flash on the Ultimate SU650, 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. The Ultimate SU650 is rated for sequential read speeds of up to 520 MB/s and 320 MB/s write; random IOPS reach up to 20K for reads and 75K for writes.
The SSD's price at launch is unknown. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. ADATA guarantees an endurance rating of 280 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
