WD Black SN850X NVMe SSD vs Crucial P310 NVMe SSD

The WD SN850X is the stronger drive for gaming and sustained writes. It uses TLC NAND with a DRAM cache, reaches 7,200 MB/s reads and 7,300 MB/s writes, and its Game Mode 2.0 software is a real extra on Windows. The Crucial P310 is a DRAM-less QLC drive with a heatsink and a five-year warranty; it is fine for everyday use and laptop upgrades but slows more under long writes. Owners and reviewers rate the SN850X highly for consistent speed; the P310 is the budget-minded pick.

• Choose the WD SN850X if you game, move large files, or want the fastest sustained performance and a DRAM cache.
• Choose the Crucial P310 if you want a simple, cool-running drive with a heatsink and a long warranty for everyday tasks.
