The Pichau Aldrin Pro is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Pichau Aldrin 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. Pichau has installed 128-layer TLC NAND flash on the Aldrin Pro, 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 Aldrin Pro is rated for sequential read speeds of up to 7,300 MB/s and 5,200 MB/s write; random IOPS reach up to 900K for reads and 800K for writes.
At its launch, the SSD was priced at 105 USD. The warranty length is set to one year, which is quite short for the SSD industry. Pichau guarantees an endurance rating of 500 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
