back to article Intel unveils gen 2 Optane SCM, bellows: You Barlow Pass, as it unfurls roadmap

Intel has dropped the veil on its gen 2 Optane technology, code-named Barlow Pass, although the details are still light, and revealed it is developing 144-layer QLC (4bits/cell) NAND technology. Chipzilla is also opening a second Optane development line at its Rio Rancho, New Mexico facility, and will be running second …

    QLC - no thanks

    Until QLC has been in use for years to build a reliability and lifetime database, I will not trust it for anything important.

      I will only use the upcoming OLC (8-bits-per-cell) drives.

    Does that stand for Side Channel Memory?

    Persistent storage + Spectre + Meltdown (or their successors) - what could possibly go wrong?

Wondering out loud if this has anything to do with their long time partner SAP?

    Sly naming rights, "Sapphire" along with 3rd generation XPoint". Strange that the two are now "Tick-Tocked" together....,
