Samsung now mass producing 512GB storage for phones
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:

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.
