The Samsung 850 EVO 4TB SSD Review

AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.

The 4TB 850 EVO is slightly faster overall on the Heavy test than the 2TB 850 EVO, so it takes over as the fastest TLC drive. The 1TB and 2TB 850 Pros are only a little faster.

Average service time of the 4TB 850 EVO has regressed somewhat compared to the 1TB and 2TB models, but it still can't be beat by TLC from anybody other than Samsung.

The quantity of latency outliers experienced by the 4TB 850 EVO places it at the bottom of the highest tier of drives and below the 1TB and 2TB models.

The 4TB 850 EVO uses very slightly more power than the 2TB, but both are much more efficient than the 1TB model and score reasonably well given the high capacity.
