    Hi,

    Hybrid drives combining a HDD and a small SSD already exist.

    Cheers, :)

    Not in the way I described. First, hybrids have NAND not actual DRAM like Iím talking about. Two, a HDD with internal hardware raid doesnít exist that Iím aware of.

    Hi,

    Why use volatile RAM for caching ? Every time the machine restarts it will have to rebuild the cache.
    As for hardware controlled RAID in a HDD, I fear that the cost will be tremendous to implement that.

    1.DRAM is faster than NAND
    2. You could upgrade the amount of RAM if it used a SODIMM slot.
    3. Infinite read/write cycles.
    4. No volitility if a small button battery were added to keep voltage on RAM. Also a copy of the RAM cache could be stored to disk and dumped back to RAM after power is restored. Sort of like a hibernation file.

    The internalized RAID setup would be expensive at first but would get cheaper as time went on and became more common.

    Hi,

    What you're describing is how a dedicated raid controller works.
    Why would you want to build it inside a HDD which has a relaitively short lifespan compared to a dedicated card which can take care of a multitude of drives at once .
    Moreover it can do a whole raft of raid configuration and combination thereof in one go.

    The controlers still exist for SAS drives for instance. Maybe for plain SATA drives as well but I haven't come across any as yet.
    Nowadays SSD sata drives are becoming much more accesible and faster and faster, especially the NMVe ones or systems using VROC raid setups.

    All in all I doubt any manufacturer would invest in developping HDDs much further except for higher and higher platter densities.

    Things get miniaturized and simplified all the time. No reason to think that an integrated RAID for a consumer HDD wouldn't do the same :)

    Also dedicated RAID controllers aren't something that you see in a PC sold @ Best Buy.

    As for the short lifespan of HDD's, mine are usually in service 3-5 years.

    There has got to be some way to make a traditional spinning disk more multitask friendly. It pissed me off when my PC is basically locked up because Windows 10 is churning the drive while installing updates or whatever other program wants to spin the disk @ 0.01 Mb/s.

    Hi,

    Sure but who'd invest in such a controller for a single disk. You'd basically need at least two indepent disk platter controlers, one raid controler too... And then there are format restrictions and so on. Feasible technically I'm sure but economically ?
    IOW, if it were realistic then I'm sure they'd done years before ssds hit the market.

    HDDs are mechanical devices so there's always the high latency because of that. If it were me I'd buy an ssd and use the spinner for sorage only.
    Hybrid HDD's aren't all that bad and offer up to 4 Tb of storage should you need it.

    Cheers,

    How did this thread get off the Optane of the OP ?
