Samsung 870 EVO
Score: 79/100
Fanxiang S101
Score: 62/100Rankings
The Samsung 870 EVO 1TB SATA SSD delivers top-tier SATA performance, a dedicated DRAM cache and strong endurance in a compact 2.5" form factor. It is limited by the SATA III interface and can see latency spikes under heavy sustained writes. Best suited for users upgrading laptops or desktops who need reliable, high-capacity SATA storage.
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.

Reviewers consistently describe the 870 EVO as the pinnacle of SATA SSD performance, applauding its ability to hit the full 560/530 MB/s sequential ratings and its markedly improved QD1 random reads. They also commend its endurance and the inclusion of DRAM, while noting that the drive remains bound by SATA's bandwidth ceiling and offers few architectural leaps over the 860 EVO.
Consumers love the noticeable boost in boot speed, the silent operation, and the ease of use provided by Samsung Magician. The most common complaints revolve around occasional compatibility tweaks on older hardware, the lack of flashy pricing incentives, and the perception that the performance gains are modest compared to a jump to NVMe.
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.
