Crucial T705 2TB NVMe PCIe 5.0 vs Samsung 990 Pro 2TB NVMe PCIe 4.0
The Crucial T705 offers significantly higher performance for users with PCIe 5.0 compatible systems and demanding workloads, while the Samsung 990 Pro provides excellent performance and superior value for the vast majority of users on PCIe 4.0 platforms.
AI Verdict
Samsung 990 Pro 2TB NVMe PCIe 4.0 wins overall.
By the numbers
Performance
Pick A wins
The Crucial T705 boasts nearly double the sequential read and write speeds (14500 MBps read, 12700 MBps write) compared to the Samsung 990 Pro (7450 MBps read, 6900 MBps write) due to its PCIe 5.0 interface.
Value for money
Pick B wins
The Samsung 990 Pro offers comparable capacity and endurance at less than half the MSRP ($179 vs $369), making it a far more cost-effective solution for its performance.
Power efficiency
Pick B wins
PCIe 5.0 drives generally consume more power and generate more heat than PCIe 4.0 drives, giving the Samsung 990 Pro an advantage in power efficiency and thermal management.
Future-proofing
Pick A wins
The Crucial T705's PCIe 5.0 interface positions it better for future high-bandwidth applications and upcoming hardware generations, though current real-world benefits are limited for most users.
Pick A if…
- • You have a motherboard with a PCIe 5.0 M.2 slot and a CPU that supports PCIe 5.0.
- • You frequently transfer extremely large files (e.g., 8K video editing, massive game development assets).
- • You want the absolute fastest sequential read/write speeds available for bleeding-edge performance.
Pick B if…
- • You have a PCIe 4.0 compatible system or an older PCIe 3.0 system.
- • You prioritize excellent performance at a significantly lower price point.
- • You are a gamer or general user where the real-world performance difference between PCIe 4.0 and 5.0 is negligible.
