Spec snapshot
| Spec | Samsung 990 Pro 1TB | WD Black SN7100 1TB |
|---|---|---|
| Capacity | 1 TB | 1 TB |
| Interface | PCIe Gen4 NVMe | PCIe Gen4 NVMe |
| Form factor | M.2 2280 | M.2 2280 |

Figures are indicative; real-world speeds depend on motherboard slot generation and cooling.
Where each wins
Performance for the end customer
Both deliver excellent sequential and random performance for gaming libraries and creative work. The 990 Pro often posts slightly higher sequential numbers on paper; day-to-day game load times are usually within a few seconds of each other when the rest of the system is equal.
Platform requirements
Both need an M.2 2280 NVMe slot. Full Gen4 speed requires a Gen4-capable motherboard/CPU. In a Gen3 slot either drive will run slower than its rating. Check whether the board supplies an M.2 heatsink—sustained writes benefit from cooling.
Software and warranty perception
Samsung Magician and WD Dashboard both offer monitoring and firmware tools. Warranty length and conditions should be confirmed for the exact SKU sold in your market.
Practical recommendation
| Scenario | Prefer |
|---|---|
| Maximum sequential rating priority | Samsung 990 Pro |
| Strong gaming brand preference | WD Black SN7100 |
| Price is close | Either; pick stock |
| Motherboard only has Gen3 M.2 | Save money on either |
End customers should treat both as premium Gen4 choices and focus on current street price and availability. Dealers, stockists and super-stockists must confirm live stock, warranty terms and pricing before quoting.
