PNY CS2340 1TB NVMe SSD vs Samsung 990 EVO Plus SSD 1TB

Both are 1TB M.2 2280 NVMe drives with similar sequential speeds, so the choice comes down to platform flexibility and track record. The PNY CS2340 claims slightly higher peak sequential numbers on a Gen4 x4 link. The Samsung 990 EVO Plus runs on either Gen4 x4 or Gen5 x2, carries a 600 TBW endurance rating and AES 256-bit encryption, and has a large base of owner ratings behind it. Buy the Samsung for a laptop or a system where power draw and proven reliability matter; buy the PNY if you want the highest advertised sequential read on a Gen4 desktop.

• Choose the PNY CS2340 if you have a Gen4 x4 slot and want the highest advertised sequential read and write figures of the two.
• Choose the Samsung 990 EVO Plus if you want a drive that works in Gen4 x4 or Gen5 x2 slots, with encryption and a long public track record.
