In this week’s poll we asked you how much storage is enough. Currently, most popular phones come with 32GB-64GB and the most you can get is 256GB. Samsung intends to change that as it started mass production of 512GB eUFS storage.
The new storage has the same physical dimensions as the current 256GB storage, good news since internal space in phones is at a premium. Samsung built it out of 64-layer 512 gigabit chips, eight of them, while the older eUFS storage used 48-layer chips.
The new storage promises 860MB/s sequential reads and 255MB/s sequential writes. It takes 6 seconds to copy a 5GB file from this storage and 20 seconds to copy to it. Samsung estimates you can store 21 hours of 4K video on these new chips.
Performance for apps is similar to the previous generation – 42,000 IOPS and 40,000 IOPS respectively. Compare them to the Application Performance Class of SD/microSD cards:
|Tech||Random Read (IOPS)||Random Write (IOPS)|
|Samsung 512GB eUFS||42,000||40,000|
|Samsung 256GB eUFS||45,000||40,000|
Samsung intends to use these new 64-layer chips in SSDs and memory cards as well, not just phone storage. Production of these as well as the older 48-layer chips will be increased in the future so expect mid-range phones to get more storage as well.
