Samsung 990 PRO vs WD_BLACK SN850X vs Crucial T700: NVMe SSD Battle
The WD_BLACK SN850X wins on value, the Samsung 990 PRO leads Gen 4 performance, and the Crucial T700 delivers PCIe 5.0 speeds that only professionals will fully exploit.
Overview
The NVMe SSD market in 2024 offers buyers a fascinating crossroads: do you invest in a proven, polished PCIe 4.0 drive, or leap into the blazing-fast but demanding world of PCIe 5.0? This three-way battle pits two of the finest Gen 4 drives against each other — the Samsung 990 PRO and WD_BLACK SN850X — while the Crucial T700 crashes the party with next-generation PCIe 5.0 muscle. All three offer 2TB capacity, 1,200 TBW endurance, and 5-year warranties, so the differences come down to speed tiers, thermal behavior, features, and value.
Design Comparison
All three drives share the standard M.2 2280 form factor, making them physically interchangeable in compatible motherboards. The Samsung 990 PRO sports a clean, professional aesthetic with a dark label and no included heatsink on the base model — though Samsung does sell a heatsink variant. The WD_BLACK SN850X leans into gaming culture with its bold black label and aggressive branding, also shipping without a heatsink on the standard model. WD offers a heatsink version as well, which is particularly useful for PlayStation 5 installations.
The Crucial T700 is the outlier here: while it technically ships in a bare M.2 form, Crucial strongly recommends — and sells — a heatsink model, and for good reason. PCIe 5.0 controllers generate substantially more heat than their Gen 4 counterparts, and running the T700 without thermal management in an enclosed case is a recipe for throttling. If you're considering the T700, budget for the heatsink model or ensure your motherboard's M.2 slot has robust integrated cooling.
