Remember the X CD rom speed craze?
Seems like it topped off at quad speed in '94 then 8X, 12X and even 16X P-CAV drives came out.
True-X at 42X and 72X showed promise as they didn't sound like a Pratt & Whitney firing up when accessing inner tracks. Their digital audio extraction was super fast but unfortunately plagued with errors.
My Plextor SCSI optical drives, both caddie and tray were very reliable. And DAE speed was nothing to sneeze at either.
And speaking of mid 90's back in the day with EZ CD creator it was considered nearly impossible to burn a CD at 2X speed on the fly without buffer underruns. And when you did make a coaster it was a big deal because blank discs were close to ten dollars apiece!
Let's not forget the slot loading craze. Loved the Pioneer 6X DVD drives.
USB flash drives replaced Zip drives. I never liked Zip drives. The Jaz drive was capacious and fast but since it was actually hard disk tech with flying heads the carts were very susceptible to physical damage. Syquest had their Syjet 1.5GB which was HUGE back in 1997. Faster than most hard drives. But also very failure prone. GTFF (guarantee to fail factor) about equivalent to JTS hard drives. (remember those?) At least the Quantum Bigfoot drives were reliable. But slow as pouring maple syrup at Kemi in January.
