Just a few days ago, we reviewed a quad-level-cell SSD for the first time ever. The experience left us wanting more. Not more QLC, to be clear. We want more of the comforting, familiar march of virtually indistinguishable drives based on various manufacturers' 3D TLC NAND that we'd been living through till recently. Soon, we may be looking back on those days wistfully. But you can't always get what you want, so today we've got another QLC drive on hand. Meet Crucial's P1 500 GB.The 860 QVO's role was cut and dried: to offer a sort of middle ground between smaller, faster SSDs and larger, cheaper mechanical storage.
