A few words about…
The first drives of the line with this name appeared in 2015. They were very similar to the 840 Evo, instead of planar crystals of 128 Gbps 32-layer 3D of the same capacity were used.
In the older model there is even the same tri-core MEX controller as in the 840 Evo, and the rest received dual-core, but improved MGX, working in combination with LPDDR2 memory with a frequency of 1066 MHz and a capacity of up to 1 GB. At the same time, the drive (like its predecessor) was positioned as a competitor to mid-range devices - at that time, mainly using MLC memory. However, even those had only a three- and not a five-year guarantee, which became the visiting card of the Evo family. Including, and appeared a little later modification of 2 TB - which at that time was a very serious value, so it required the emergence of a special controller MHX (at the same time, and DRAM-cache in this model was transferred to a faster LPDDR3-memory).
