We already know more details of the new generation of SSD NVME Samsung PM981 units. Among its specifications, we find a controller Samsung Polaris V2, a format 2280 and rates of writing/reading that is very fast.
Samsung 96-layer V-NAND memories
In the following table, we can see the main characteristics of the successor generation of the series 950 EVO. The Samsung PM981 will feature the new Samsung Polaris V2 controller and 64-layer NAND Flash TLC memories. We are surprised that in this range of high performance this model of memories is used. Remember that they have a worse longevity than the memories of the MLC range.
It seems that the main criticisms of her little sister ‘ Samsung 950 EVO ‘ have not served much to get a higher model, at least for now.
