    "demand for such HDDs is expected to grow in the coming years, particularly in China"

    no its not. unit shipments will go down not up. dubious claims about "network recorder market" will not be reversing a decade long trend.

    just because you put "china" and "growth" in one sentence, doesnt mean its automatically true. on what grounds are about to see a major shift in the market?

    SSDs have double in GB per dollar in the last 18 months alone. to think that will have no impact, that no pct of the market will care? and there will be no market share loss, because SSDs "ARE WAY TOO EXPENSIVE" as my replies will be pointing out.

    HDD unit shipments in 2020 will be 70% of 2019. and in 2021 it will be 70% of 2020. its called exponential decay to zero.

    its been doing that b4 3D nand showed up. its been doing that for a decade. and no amount wishful thinking will over ride that.

    " HDD unit shipments in 2020 will be 70% of 2019. and in 2021 it will be 70% of 2020. its called exponential decay to zero. " source for this ??

    " when was the last time you used an optical disc "?? last night actually.. i STILL put optical drives in my comps, and will continue to do so, as i still use them. the DRM, is crap.. some can be disabled just by disabling the autoplay feature...

    " hard drives are not as sticky as optical drives and will die even faster. " thats hard to say.. it really depends on how the ssd market grows, and expands as far as size and prices, drives above 1 tb here.. are still a tad on the expensive side compared to mechanical hdds ...

    "source for this ??" if you had read the next sentence, I already answered you. on top of that there is data from a company that makes hard drive motors.

    didnt even see that post back in may.... interesting... but still.. ssds is no match for the space mechanical storage is able to provide for the price.. a 4 tb ssd, starts at $720 here, 4 tb mechanical, starts at $150 as i said.. still a tad on the expensive side....

    You need to look beyond the headline. The implosion is in PC hard drives. Surveillance applications would either be data center - which is growing - or consumer electronics - which is slowly shrinking. In the latter case the shrinking is probably due to the decline in home TV DVRs (and which will probably accelerate in the nearish future because the PS5 and XBoxNext are both expected to use SSDs not HDDs for storage). SMB video surveillance could easily be a growing segment within the CE bucket even as the entire market as a whole continues to shrink.

    storing video is the worst possible application for ssd's, unless you are live editing it. and even then linear video editing is totally acceptable on an ssd. people used to do that on TAPE AND FILM you know...

    The rated annual workload equates to a sustained data transfer rate of under 6MB/sec.This seems low for the stated application even with extensive upstream data compression.

    ppl said optical drives are not going away. because the offline cold storage of disks was too precious and too valuable. what was the last time you used an optical disk ??

    and optical disks/drives had a huge advantage that HDD dont have. i call it "established investments". ppl who had bought large number of movies on DVD and blu ray would need to buy players or lose their library. ppl who kept buying players were a large market for future movies. same with games and consoles. it also had a DRM advantage for record companies who wanted to control hardware and not just software and yet it died and no one missed it.

    hard drives are not as sticky as optical drives and will die even faster.

    I'm using my optical drive today.
    I like it. It's very good for booting Linux, backing up data to permanent storage, etc.
    Just because the manufactures wanted to save space and a few bucks doesn't make the technology bad or dead.

    Hey! I can make the same argument about steam locomotives: The era of steam locomotives is NOT over! You don't believe me? There are many people who love steam locos, i am one of them. And there are many steam locos still in operation. And just yesterday i was taking a ride on a steam train. Just because locomotive manufacturers have some reasons to not build steam engines anymore doesn't make steam locos bad or dead.

    And Union Pacific doesn't just run their steam locomotives around to allow people to take pictures, they haul actual revenue trains with them. Even some of those smaller tourist railroads, where you ride behind a steam locomotive on the weekend, haul freight with the same locomotive during the week.
  • TheSkullCaveIsADarkPlace - Friday, December 6, 2019 - link

    Yeah, railroads in Europe do this on main and branch lines as well, occasionally. Mostly in passenger service (both as part of the regular train schedule or as special charter trains), but doing some freight services once in a while is also not unheard of. :)

    I also have a unicorn in my backyard. I needed to muzzle it so that it stopped poking me with it's horn, but there are no muzzles for unicorns. You know what I did? I used an old Slackware CD! So we really do need optical drives!

    More seriously, in 2009 the M-Disc came out and it's still used by quite a few people for permanent storage. The M-Disc has not been bettered by modern SSDs, HDDs, Tapes, or any other consumer oriented product I'm aware of. Thus optical drives are still a worthwhile investment for a user interested in long term storage solutions (everyone).
    The alternative someone uninformed will point me to is cloud storage. In case you've never read the user agreement, I know people who have (but not for every storage provider), and they state that the storage is not permanent and that data loss can occur at any time through a disclaimer of liability.
