Back when I was an intern at Imprimis (before they got bought by Seagate), I worked with the Manufacturing Engineers for the Wren series of 5.25” drives, including the Wren VII, which was the first consumer SCSI drive with a capacity of 1GB or more. I looked at the drive actuators at the time, and I was incredulous when the guys told me that all operations were serial. I asked why they didn’t do parallel reads and writes, and I was told that technology was already common for mainframes but too expensive for consumer gear. So, fast forward from 1989 to now, and I’m sure that idea will come back — sooner or later.
