PNY CS900 500GB SATA III 2.5"
The 500GB SATA III drive delivers 550 MB/s read and 500 MB/s write speeds, with TLC NAND and a DRAM-less design that keeps costs down. Its 200 TBW endurance and 2,000,000-hour MTBF offer reliable daily use, while the 2.5-inch form factor fits most desktops and laptops. This is best for budget-conscious buyers upgrading an older system for faster boot times and everyday file storage, not for heavy workloads or portable use.
