Our Verdict

At $53.79 for 250GB ($0.215/GB), the PNY CS900 250GB is the most expensive drive per GB among the sub-300GB options in this batch. Sequential reads reach 515 MB/s; writes land at 400 MB/s, reflecting a budget controller at this price tier. TBW endurance is 100, adequate for a light OS drive. The Patriot P210 256GB ($39.99, $0.156/GB) covers near-identical capacity for $13.80 less, with 500/400 MB/s speeds and 80 TBW — the performance difference is negligible in real-world use on SATA. PNY's 5,327 reviews outpace the P210's 6,093 only marginally. Both 250–256GB options are capacity-constrained for a primary drive in 2026: Windows 11 can occupy 30–50GB after updates, leaving under 200GB for applications and files. Either works as a dedicated OS boot drive paired with secondary HDD or SSD storage; neither is appropriate as a sole drive for a general-purpose machine. Right buy for: SATA-only systems that need a small, dedicated OS-only drive and already have separate file storage — step down to the Patriot P210 256GB ($39.99) to save $13.80 unless PNY brand compatibility is a specific requirement.
