Samsung 990 Pro 1TB NVMe PCIe 4.0 vs Samsung 870 EVO 1TB SATA III
The Samsung 990 Pro is a high-performance NVMe drive ideal for demanding users, while the Samsung 870 EVO is a solid, more affordable SATA SSD suitable for general use and older systems.
AI Verdict
Samsung 990 Pro 1TB NVMe PCIe 4.0 wins overall.
By the numbers
Performance
Pick A wins
The 990 Pro offers significantly higher sequential read/write speeds (7450/6900 MBps) compared to the 870 EVO (560/530 MBps), making it vastly superior for tasks requiring fast data transfer.
Value for money
Pick B wins
The 870 EVO offers comparable capacity and endurance for $10 less, providing better value for users who don't require extreme speeds.
Power efficiency
Pick A wins
NVMe drives generally consume less power than SATA SSDs, especially under load, making the 990 Pro more power-efficient.
Future-proofing
Pick A wins
PCIe 4.0 NVMe is the current standard for high-performance storage, offering significantly more bandwidth and better compatibility with future systems than SATA III.
Pick A if…
- • You are building a new high-end PC or upgrading a system with a PCIe 4.0 M.2 slot.
- • You frequently work with large files, video editing, 3D rendering, or demanding applications that benefit from extremely fast storage.
- • You want the absolute best performance for gaming, reducing load times and improving overall system responsiveness.
Pick B if…
- • You are on a tighter budget and need reliable 1TB storage for general computing tasks.
- • Your motherboard only has SATA III ports or lacks an M.2 slot, or you need a 2.5" drive for a specific enclosure.
- • You are upgrading an older system where the performance difference of NVMe would be bottlenecked by other components.
