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.
The SanDisk Optimus GX 7100M is a PCIe Gen4 x4 NVMe SSD in the compact M.2 2230 form factor, built on the SanDisk A101-000171-A1 controller (DRAM-less/HMB) and 218-layer BiCS8 TLC NAND. It delivers sequential reads up to 7,250 MB/s and writes up to 6,900 MB/s. Reviewed by Tom's Hardware in August 2026, it was called "the best 2230 drive you can buy," making it a strong candidate for the Framework Laptop 12 and Framework Storage Expansion Cards.
The WD_BLACK SN7100 is a PCIe Gen4 x4 NVMe SSD (NVMe 1.4) in the M.2 2280 form factor, built on the WD/SanDisk Polaris 3 A101 controller and Kioxia 218-layer BiCS8 TLC NAND. Despite the high "7100" model number it is a PCIe Gen4 drive, not Gen5. It delivers sequential reads up to 7,250 MB/s and writes up to 6,900 MB/s with notably strong power efficiency, and was used in the Framework Laptop 13 Pro review unit tested by Tom's Hardware.
The XPG Mars 970 Plus (ADATA part AMTG970P) is a PCIe Gen5 x4 NVMe 2.0 SSD in the M.2 2280 form factor, built on the Silicon Motion SM2508 controller (TSMC 6nm) and 232-layer 3D TLC NAND. It delivers sequential reads up to 11,000 MB/s and writes up to 10,000 MB/s in a single-sided, laptop-friendly design. It is now offered directly by Framework on the Framework Laptop 13 Pro DIY Edition, where Framework qualified it for better performance, efficiency, and long-term reliability.
