Samsung unveiled its new flagship solid-state drives: 970 970 Evo and Pro. These models are made in the format M. 2 2280, support NVMe-based controller Samsung Phoenix.
The main difference is the memory type. Junior 970 Evo uses memory V-NAND TLC, and the older 970 Pro is based on V-NAND MLC. Hence, in theory there must be a difference in survivability, but modern SSDS in General are quite reliable, regardless of the type of memory.
Despite the different memory speed performance of the new products are very similar. Detailed parameters are described in the tables.
As you can see, the differences are really minimal. As for actual performance, colleagues from AnandTech have tested the drives.
In fact, the difference in the results corresponds to the difference in performance characteristics. Prices, as you can see, are quite reasonable, considering the characteristics of new products. True, the drives obviously are more expensive.
