Our Take

Best for: Gamers and content creators needing massive fast storage.

0 NVMe SSDs on the market, and this 8TB version with the included heatsink is a powerhouse for anyone who needs both speed and capacity. Read speeds up to 7,300MB/s make load times nearly non-existent, and the 8TB capacity means you can keep your entire game library installed without juggling files. 0 for optimized performance. 0 is still plenty fast. At $400 off the original price, this is an excellent deal for a high-end storage upgrade.
