All this makes the Samsung EVO 870 the fastest SATA SSD on the market. An important improvement in practical use is the significantly improved sustained performance. This means a significantly later drop in performance of the SSD under high sustained load. From the 1 TB version onwards, there is no longer any measurable drop in write performance in tests at all, even if the SLC mode, which Samsung calls “TurboWrite”, is no longer active.
As with the Samsung EVO 860, five storage capacities are available for its successor, the EVO 870, ranging from 250 gigabytes to 4 terabytes.
