Technology we could rely on in the last century.
It started with Winchester Drives then the MFM & the RLL drives, which needed manual parking & low level formatting.
Later it became the three and a half inch Magneto mechanical hard drive.
On my Amiga computers the Fujitsu HDDs spin* at a dizzying 10.000 RPM!
The Fujitsu is an Ultra Wide 68 pins SCSI HDD, with a transfer speed so high my Amiga never had to wait for data from the drive.
