Samsung 990 PRO
Score: 81/100Rankings
The Samsung 990 PRO 1TB is a high-performance PCIe 4.0 NVMe SSD delivering up to 7,450 MB/s read and 6,900 MB/s write speeds with strong security features. Its heatsink-less design and limited pSLC cache can limit sustained heavy workloads. Best suited for gamers, content creators, and professionals who need maximum PCIe 4 throughput on desktops or laptops with adequate cooling.
The Fanxiang S101 1TB SATA SSD offers an affordable upgrade path for older laptops and desktops, delivering up to 550 MB/s read speeds with reliable TLC NAND. Its limitations include the SATA III bandwidth ceiling and lack of advanced features such as DRAM cache or hardware encryption. It is best suited for budget-conscious users needing a simple storage boost on legacy systems.

Professional reviewers consider the S101 a solid, low-cost option for users who need a simple SATA upgrade. While it delivers the expected speed gains over HDDs, its SATA III bandwidth and lack of premium features make it unsuitable for performance-critical workloads, and external use via USB shows markedly lower speeds.
Professional reviewers commend the 990 PRO for its exceptional speed, gaming-optimized random performance, and strong reliability, while noting the smaller DRAM cache and lack of a heatsink as potential drawbacks under heavy sustained loads.
Everyday users praise the drive's blazing speed and security, but note concerns about the smaller DRAM cache and possible throttling without a heatsink.
