Comment on Cursed 32 Gig NVMe drive?

  More or less. Fusion Drive was introduced when high capacity SSDs were rather expensive. Although the SSD part had 128 GB iirc. Apple stuck with Fusion Drive BTO options for way too long and also nerfed it to 32 GB as evidenced here.

  Man, Intel seriously needs to license Optane out. That technology represents a new paradigm for digital storage. It’s cheaper to manufacturer than flash memory and its speed is more comparable to RAM than flash, it’s at least an order of magnitude faster than current nvme drives. It’s also three dimensional, so there’s potential to make super fast terabyte, even petabyte sized drives.

  I wish the world was competing to make better Optane/xPoint drives like they are with flash, it’s a shame the tech is locked behind a patent…

    As someone who has performed data recovery on optane systems. No, just no.

    There’s larger slow mechanical storage.

    Faster flash and xpoint storage

    RAM.

    Any device can use a level up to cache and appear faster.

    But RAM caching is generally better handled by the OS itself.

    Flash coaching isn’t an awful idea except when it goes wrong your back to “safety remove disk” being absolutely vital. So the OS needs to be aware and cutting power at the wrong time can kill your install.

    Every update says “so not turn off your computer” for a reason but the actual redundancy we now have is leagues better than 10 years ago

    God forbid one component in an optane chain becomes unreliable.

    Ultimately everything needs to run in RAM. Everything needs persistent storage. A non-standard middle step between persistent and volatile memory is best avoided.

    Xpoint was an interesting experiment but CXL replaced it. Ultimately the choice for data centres is to support more RAM. The additional RAM replacing the optane cache while the waits to be written is more compatible and predictable.

    You can now have terrabytes of RAM and if you rarely boot and have redundant systems. There’s need for the middle step.

    The cost of memory and SSD per gigabyte as a cache matters. But RAM error correction and other protocols give even more advantages to avoiding optane.
