There are physical limitations. An electron trap will have a minimum size. New ways for leaps and bounds need to be discovered. I think it's not reasonable to assume that both magnetic and electric storage have the same maximum density of infinity.
- baybal2 6y agoRead/write speeds will be the limit. How many years it will take to write 120TB on it? A 120TB flash array can be written in minutes with enough upstream bandwidth, and takes just one rack. Tape on other hand was always speed limited, is just fine in its nice with that limitation.
- jbverschoor 6y agoDoesn't take a whole rack. You can literally buy 4 x 30TB 2.5" SSDs and have 120TB.
- wtallis 6y agoIf you want to be able to read or write the full 120TB in a few minutes instead of 4+ hours, you need to use SSD smaller than 30TB.
- gbrown_ 6y agoUnlike disks flash has the nice advantage that it's not really constrained by form factor though. With a server full of E1.L drives you get strong performance and large storage in a dense space. Of course that's eye-wateringly expensive today but I think the combination of these factors will be what displaces disks rather than purely $$$/TB.
