Brief Essay On Hard Drive Technology
Hard drive technology The mechanics of hard disks are much more precise than the mechanics inside the humble floppy – hence the extra expense. The surface of the disk drive is housed in a hermetically sealed unit (which keeps out all the dust, grit, tomato sauce, biscuit crumbs and smoke particles etc. ... The rotational speed of the early hard disks was typically 10 times that of a floppy, and was thus about 3000 rpm, but the latest disks rotate at 5,400 rpm or even 7,200 rpm, thus improving performance considerably. The early small hard disks had very modest capacities of about 5 Mbytes, but today’s hard disks have several Gbytes, even on the most basic of microcomputer systems.
