I have two optical drives. The one in my iMac and an external FW optical drive.
To this day, I, too, still get a lot of use out of these drives!
I don't think it's that ridiculous that there are still users out there using optical media.
Using optical media for important data backups is still far cheaper and more reliable and stable for long term data storage than continually adding/replacing expensive external hard drives where you'll be lucky if these newer hard drives last 5 years, no?
I STILL have important backed up data on optical discs that is over 10 years old and still readable!
This is a hard claim to make with any of the newer crop of avaialble hard drives that are out there.
I just had almost 12 year old 256 GB WD external FW 400 hard drive that finally started giving me problems where I, April 2015, i had to replace with a new external FW800 hard drive.
I don't think these new hard drives are going to last as long as that one did!
And there is no other new types of "more permanent" media to long term store important data onto.
