@yukku16: Here is how insane HDD head technology really is. If you scale up that tiny read/write head to the size of a 70-meter Jumbo Jet, the physics become absolutely mind-blowing. Imagine this Boeing 747 screaming at a super-low altitude of just 1.6 millimeters off the ground. It’s blasting along at Mach 2,800—that's about 3.4 million kilometers per hour, fast enough to leave spacecraft in the dust. And while it's flying at that ridiculous speed, it has to scan every single grain of sand on the ground, reading them as "black or white" without missing a single grain. That is the level of absolute mad precision happening inside a hard drive. SSDs might be the standard now, but you’ve gotta love the pure mechanical romance of this tiny metal box pulling off this hyper-G, nano-scale miracle flawlessly for years. #HDD #HardDrive #PCMR #Physics #fyp
