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 2 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 absorbed more quickly. The cache is sized at 691 GB, once it is full, writes complete at 2159 MB/s. Copying data out of the SLC cache (folding) completes at 863 MB/s. 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 7,400 MB/s and 6,600 MB/s write; random IO reaches 1000K IOPS for read and 1000K for writes.
At its launch, the SSD was priced at 159 USD. The warranty length is set to one year, which is quite short for the SSD industry. Pichau guarantees an endurance rating of 1000 TBW, a high value.
