Samsung 870 EVO
Score: 79/100Rankings
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 PNY CS900 1TB is a budget-friendly 2.5-inch SATA III SSD delivering solid sequential speeds and low power draw. Its main trade-offs are limited SATA bandwidth, lack of endurance data and advanced features. Best suited for users upgrading older laptops or desktops where cost and basic performance matter.

Professional reviewers and editors are scarce for this model; vendor and spec-sheet commentary positions the CS900 as a reliable, value-oriented HDD replacement, emphasizing its solid sequential performance and low power draw while noting the lack of advanced features found in higher-end SSDs.
Everyday users appreciate the noticeable speed boost over HDDs, especially faster boot and application launch times, and the quiet, low-heat operation. However, the limited amount of user feedback and absence of detailed endurance specs generate some uncertainty about long-term durability.
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.
