Corsair MP300 NVMe SSD (M.2 2230)
The Corsair MP300 is a PCIe Gen4 x4 NVMe SSD in the M.2 2230 form factor. The 2TB variant is confirmed working in the Framework Laptop 12 (Intel). Note that Corsair reused the "MP300" model name across two revisions — the 2024 batch uses a Phison E27T controller with 162-layer Kioxia TLC NAND, while a newer revision uses QLC NAND, so check the listing carefully if longevity matters.
