SSD storage technology continues to improve by giant companies. And Samsung is leading the innovation, announcing the fifth generation of V-NAND. That will increase the number of layers up to 96 with relatively few other changes in the form. The fifth generation comes with Samsung’s first QLC NAND flash (four bits per cell), with a capacity of 1TB (128 GB) per slot. 96-layer memories: Increased storage, durability, and lower power consumption

96 layer V-NAND 11 percent higher data writing speed
Last year, Samsung had announced its fourth generation of 3D NAND, with the 64-layer design. This fourth generation of V-NAND is now in production. And will be used in many products in the coming months. Most products will use 256GB or 512GB TLC matrices. Compared to the 48-layer third-generation V-NAND, the 64-layer V-NAND offers the same read performance, but writing performance is about 11% higher.
96 layer RAM energy consumption
Power consumption has been ‘significantly’ improved with the current required for a read operation decreasing by 12%. And for a write operation, the required power consumption has reduced by 25%. Samsung claims that its 64-layer V-NAND in a TLC configuration can last from 7,000 to 20,000 program/erase cycles, so with this new 96-layer memory, the drives will have a longer lifespan.

Samsung also introduces SSDs based on previous V-NAND technologies. These Include a 2.5 ‘128-bit SAS SSD based on QLC. For this unit, Samsung will stack 32 arrays per packet, for a total of 4TB on each BGA device.
That is a new step in sweep out magnetic disks from the market.
