    Great stuff, but please give us 10x transfer rates as well, otherwise it will takes days to populate/empty!
    Even backing up a drive will put it out of action for so long, it wont be viable for many.
    With smaller drives, parallel backup operations make it feasible.

    If we're talking contiguous sequential reads, it should be about 10x faster. Random reads could be disastrously slow though.
    I'm sure these drives will only be on SAS, since that manages higher transfer speeds than SATA.

    In either case, I'm sure these drives will still be horribly slow to back up. They might actually be better to back up to.

    Modern hard drives are 250-260 mb/s its not THAT slow, its kinda half of SATA SSD speed, of course thats for sequential speeds, but thats what HDD used today to archive, to keep your movies/tv collections, game isos and so on.

    IF they could do that SSD drives would hella of alot cheaper.... and then there would truely be war of who can do faster and cheaper.... and we would not have SSD more then double the price for same hdd capacity. among other things..

    Only at the start of the drive.
    Average speeds are much lower and end of drive is about 1/2 the max.
    And small files dont get anywhere near that.

    would be great wouldn't it???!

    But knowing how money rules all they will conspire to keep prices stupid.


    One can dream of day we see SSD that cost same per tb as HDD

    no they aren't.

    Context clarification,
    Consumer drives sold in consumer densities do not reach this,
    Datacenter drives that don't really belong in desktop pc's (because of noise, TLER, etc) only reach this at the top densities.

    I was talking about Segate Exos x16 series that advertised as 261MB/s
    I have bunch of them in 16tb and 14tb sizes, and yep these are enterprise but these are also the one you get inside external boxes and they sold cheaper then just standard internal HDD, so people buy them and then shuck.
    So price-wise its the mainstream, even cheaper somewhat.

    no need
    even 5900rpm is plenty fast for storage
    just make 10tb+ affordable and more durable

    even if I decided to shed out for a 10tb drive,I'd be worried about 5 years warranty max
