Addlink S22 QLC SSD review: Quad-level cell NAND that sustains write speeds, on the cheap
The Addlink S22 QLC surprised me in two ways. It can sustain write performance at a hefty 450MBps even with very large files, a first for us with QLC drives. Also, it reads said large files 80MBps slower than it writes them—atypical with a vengeance. Odd or no, I’ll take that trade-off any day, given that the 1TB model I tested costs less than 9 cents a gigabyte.
Design and features
The S22 QLC is available in two capacities: 512GB (currently $48.88 on Amazon) and 1TB (currently $86.88 on Amazon). Both are 2.5-inch SATA III 6Gbps SSDs that are 7 millimeters thin, hence suitable for just about any laptop that uses 2.5-inch drives. The NAND is 64-layer QLC (Quad-Level Cell/4-bit) NAND, the controller is Phison’s S11 controller, and there’s 32MB of SDRAM on board to speed smaller transfers.
