Yesterday, Samsung's 970/980 series was exposed. It is said that Samsung will abandon the EVO/PRO naming method and only use numbers in the future.
Today, the information of Samsung 860 EVO appears in the database of SATA-IO (Serial Bus International Organization).
The 860 EVO is designed with various capacities of 250GB, 500GB, 1TB, 2TB, 4TB, 2.5-inch SATA interface, and 7mm thickness.

According to data, the 850 EVO was released in 2015. It is Samsung’s first third-generation V-NAND product, which is 48-layer TLC flash memory. In terms of performance, it can read and write continuously at 540MB/s, 500MB/s, and QD32 4KB random read and write 97000 IOPS, 89000 IOPS.

It is expected that the new 860EVO will have a slight improvement in reading and writing, but it is limited by the SATA3 interface, which is not much.

At present, the price of 850EVO 250GB is 668 yuan, occupying the top of Amazon's SSD best-selling list for many years.

Because of the advantages in the main control and flash memory, disk drop occurs less frequently, and Samsung's low-end SSD purchase value is relatively high. Of course, it seems that 850EVO is very likely to use 64-layer 4bit QLC flash memory.
