The 4TB variant of the P3 SSD from Crucial is a DRAMless design sporting the Phison PS5021-E21T controller but also four ICs of Micron’s 3D QLC NAND (176-layer N48R FortisFlash), double density this time versus the 2TB SKU. The quantity of pseudo-SLC cache has doubled, hence the speed drop after writing about 1TB, which is excellent for a mainstream drive! The drive temperatures remain decent even in the most stressful environments, so we won’t argue installing it in a laptop to get a combination of good speed and great capacity!
