Western Digital, through its SanDisk subsidiary, has introduced the 7550GB iNAND 256 e.MMC memory units for mid-range smartphones and 8521GB iNAND 256 UFS for high-end smartphones.

We are at a critical moment in the memory market and it is necessary for the main manufacturers to put the batteries to lower the price of the absurdly expensive SSD, M.2 SSD and RAM memory. Western Digital takes a small step in this direction by announcing the company's most advanced memories, the SanDisk iNAND, which will come in two different models depending on the technology used for their manufacture and which are called the iNAND 7750 and iNAND 8521. The two models of memories are based on 3-layer 64D NAND Flash technology.

The new memories presented by Western Digital are characterized by being designed only for smartphones. Specifically, the iNAND 7750 are designed for mid-range terminals that need a large amount of memory at a more reasonable price. These memories have an e.MMC interface, possibly e.MMC 5.1, which offers 250MB / s of reading and 125MB / s of writing. The iNAND 8521 memories are designed for high-end smartphones and have a UFS 2.1 interface, which is approximately ten times faster than e.MMC memories, especially designed for high-end smartphones, which have the ability to record and play content in 4K, games are played or high internet connection speeds are used.

Apparently 256GB modules may seem like a lot of capacity for a smartphone, but forecasts for 2018 indicate that a lot of capacity will be needed, because it will be a year of expansion of VR and high-resolution content, which takes up a lot of space compared to content ' traditional 'and also, there are more and more smartphones without a microSD slot, so the capacity must cover all the needs of users, if there is this restriction.
