It turned in improved benchmark results in both gaming and general storage tests (including a stellar score on the 3DMark Storage benchmark). You'll definitely want to use a heatsink with this speedster; it's available with or without one. About all it lacks is hardware-based security.

With an impressive 4,800 TBW endurance rating and a 5-year limited warranty, this drive is built to last. Now, I'll be honest, the 8 TB version uses 162-layer BiCS 6 NAND instead of the BiCS 5 found in smaller capacities, which means it's slightly slower than the 4 TB models, but it's still the fastest 8 TB SSD available and blows away the competition.

Also, while the SN850X is fast, it's priced at a premium compared to some competitors that offer slightly lower speeds, but come at a better cost.
