Samsung 870 EVO
Score: 79/100
Western Digital WD Green
Score: 63/100Rankings
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 WD Green 1TB SATA SSD offers up to 545 MB/s sequential reads with ultra-low power consumption, making it a cost-effective choice for laptops and secondary storage. Its DRAM-less architecture and modest 400 TBW endurance limit performance for demanding tasks, and it's less suited as a primary boot drive. Best for budget-conscious users needing basic storage and long battery life.

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.
“fastest SATA SSD yet”
“fast boot times”
Professional reviewers position the WD Green 1TB as a budget-oriented SATA SSD that excels in power efficiency and price, but its DRAM-less design and modest endurance make it unsuitable for high-performance or write-heavy scenarios.
General users praise the drive for its rapid game loading, smooth everyday performance, and easy installation, seeing it as a solid value for a 2 TB capacity. Recurring concerns revolve around thermal throttling without a heatsink and occasional slowdowns during long write operations, especially for those expecting flagship-level consistency.
