Why can't industrial level datacenters use custom washing machine sized disc pack drives with petabyte/platter storage? Why do they have to compete on the supply of 3.5" drives and drive consumer prices to insane levels?
>>108661677multiple reasons, first a bigger disk = better for sequential reading but most files aren't 100Gb..Think about it you have one 1000T disk VS 100 10T disk, the 100 disks have 100 reading heads and can read in parallel. In big servers we want Input/Output Operations Per Second to be high. Second is just mechanical they are just harder to make because of the vibrations. Anyway for cold storage we have better technology than HDDs.
