On Tuesday, Western Digital announced the launch of UFS 3.1 Flash, named iNAND MC EU521, that meets the latest JEDEC specification. Western Digital sees the new UFS 3.1 flash memory as designed for 5G phones, tablets, and more, speeding up scenarios such as gaming, AR/VR, machine learning, artificial intelligence, and more.
According to the JEDEC documentation, the main improvements in UFS 3.1 compared to UFS 3.0 are higher write performance, lower power consumption, and more stable performance management. To achieve write acceleration, Western Digital introduced a sixth-generation SmartSLC caching technology with a sketch of up to 800MB/s, comparable to the actual download speed of a 5G network, and would not drop even when the capacity was fully loaded.
Although the type of storage particle has not been announced, Western Digital says it is cost-effective and appears to be highly likely to be TLC.
It is not immediately clear which phone or tablet will be equipped with the Western DigitalNAND MC EU521 UFS 3.1 flash memory chip, and the iQOO 3 5G, to be released on February 25th, will be the first UFS 3.1 flash memory. The UFS 3.0 flash memory, previously introduced with the Write Acceleration Xiaomi 10 Series, can also be written to speeds of more than 700MB/s.
