Samsung 990 EVO 2TB
Score: 87/100
Crucial P310 1TB
Score: 48/100Rankings

The Samsung 990 EVO 2TB offers a balanced mix of high random performance, strong power efficiency and modern PCIe flexibility, making it ideal for laptops and compact PCs. Its DRAM-less design keeps costs and power low, though heavy write workloads may see a slowdown once the cache is depleted.

The Crucial P310 1TB PCIe Gen4 NVMe SSD delivers flagship-class sequential speeds and strong random IOPS in a compact single-sided M.2 2280 form factor, but its modest endurance and lack of hardware encryption limit its appeal for heavy-write or security-focused scenarios.

Professional reviewers praise the 990 EVO for its flexible dual-mode PCIe support, strong power efficiency and solid random performance, while noting that raw sequential speeds lag behind flagship models and sustained writes are not class-leading.
Everyday users rate the drive highly, highlighting easy installation, fast boot times and noticeable gains over older SATA or PCIe 3.0 SSDs, with occasional complaints about the lack of a heatsink and DRAM-less architecture.

Professional reviewers praise the P310 for its flagship-class sequential speeds, impressive random write IOPS, and cool operation without a heatsink, noting its compact design and 5-year warranty, but consistently flag its modest 220 TBW endurance, DRAM-less architecture, and lack of hardware encryption as drawbacks.
Everyday users are overwhelmingly positive, highlighting the instant boost in system responsiveness, easy installation, and noticeable load-time reductions, with only minor mentions of the missing heatsink.
“Excellent random 4K performance for a DRAM-less SSD, outperforming older models like the 980 PRO in some benchmarks.”

“Users consistently rate the drive highly (4.8-5.0 stars across platforms), praising its ease of installation and fast boot times.”

“The single-sided design fits perfectly in my mini-PC and stays cool.”
