The older (slower) drives will tend to last longer.
I had/have an Quantum 1.4 gig (5400 rpm ?) drive that
I bought back in 1993 for the Amiga BBS I was running
at the time. I ran that drive 24/7 365 for about 5 years.
When I shut down the BBS I installed the drive in my
A3000 for several more years (4 or 5 years). I removed it
because on boot-up it didn't always want to spin up.
With a little coaxing it will spin up and all data is
still intact.
I 'LIKE' the older Quantum drives .........
IMHO they are the best ..
