PNY CS2340 1TB NVMe SSD vs WD Black SN850X 1TB NVMe SSD

The WD Black SN850X is the stronger drive for gaming and heavy sustained writes. It has a proven controller, a large body of owner feedback, and a 600 TBW endurance rating. The PNY CS2340 claims slightly higher peak sequential read and write speeds and is a fine everyday boot and game drive, but it has far less track record. Buy the SN850X for a primary gaming or workstation drive; pick the CS2340 for a secondary drive or a budget build where peak numbers matter more than pedigree.

• Choose the PNY CS2340 if you want a fast Gen4 boot or game drive and you care more about peak sequential read and write numbers than about a long track record.
• Choose the WD Black SN850X if you want a proven primary drive for gaming, video work, or a PS5, with published random IOPS and a 600 TBW endurance rating.
