Western Digital is the first company to develop and introduce the first 512GB 64-layer 3D NAND chip, while it has initiated litigation with Toshiba.

Mechanical hard drives or HDDs are beginning to fall out of use, using only for mass storage and specific solutions that require storage capacity, not high read and write speeds. Western Digital is aware of this trend and that is why in recent years it has gone on to develop NAND type memories, specifically the latest advance in this regard is the 3GB 512D NAND chips. Toshiba and Western Digital teamed up to jointly develop solutions, and WD owns 20% of Toshiba's shares.

That was the beginning, since right now there are certain tensions between both companies. Western Digital appears to be trying to prevent Toshiba from marketing these 3GB 512D NAND modules. Everything indicates that both companies will solve their problems in court. The conflict seems to be going on for a long time and WD wants to take the initiative in this conflict and it seems that they have already decided to commercialize the aforementioned chips, without waiting for trials or anything. The development of these chips has been developed with great secrecy on the part of the company, so we do not know anything about their specifications, we simply know the most superficial data.

Both WD and Toshiba have made a big leap in development, thanks to BiCS3 technology. The manufacturing process so far was 256GB, which is very important. With the new technology it has been possible to double the density, thus doubling the capacity of these memories. These advances are very important for the industry, which will be able to develop more complete solutions. As soon as we have more data on these reports, we will offer them, but for now the data is minimal.
