PNY CS900 Spec and Price in the United Kingdom
Where the CS3140 chases flagship NVMe numbers, PNY's CS900 stays in familiar SATA territory: 550/530 MB/s sequential read/write and a three-year warranty on a 2TB 2.5-inch drive. TLC NAND keeps it consistent for everyday use, and the SATA interface makes it a straightforward swap into any older laptop or desktop still limited to SATA ports. It's positioned as a capacity-focused hard-drive replacement rather than a performance play — the numbers top out at what the SATA III bus allows.
Tied 96th of 106 models in the SSD catalog on Sequential read — 4 models share this figure. Tied 89th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.
