Hard drives had gotten much smaller, so they could be installed internally in computers. Instead floppies were replaced by hard disk drives and optical drives (CD and later DVD). The constraint was the hardware, not the little slip of magnetic media in the disk.Īs hardware improved, the need for floppy disks to become better disappeared, so not one invested in improving the technology. What mattered was how many sectors and blocks the drive hardware was capable of writing to or reading from the disk. if they were double-sided! Single-sided they only held a measly 180 Kb.Īs you can see, the physical size doesn't matter (the earlier 5.25" disks held less than the later, smaller 3.5" disks). Eventually the hardware became able to read/write on both sides of the disk, hence 1.44 Mb.īut before that, we all had to use 5.25" floppy disks, and those only held 360 Kb. ![]() It was a physical limitation of the drive hardware of the day.Įven worse: before 1.44 Mb floppy disks, the same 3.5" floppy disk only held 720 Kb. Why were 1.44mb floppy disks the standard? why are they all 1.44mb? can they get larger? if higher volumes are unreliable, why is this?
