@Mik said in I'm so old I remember when a gig of storage was a lot.:
When I was in school a 10MB hard drive would set you back $10K.
When you say 'hard drive', don't you actually mean 'stone tablet'?

On a more serious note, we've stopped using HDD's for backup.
We had one, and the manufacturer didn't update the drivers after Windows 7, and it now refuses to work with Win10, so we can't access the data without going through a right old bunch of bullshit.
Tossers.
I was only joking

The saying, "Lite is just one damn thing after another," is a gross understatement. The damn things overlap.

Formatting and links are goofy because I copied from an email.No, I wouldn't use an SSD, either. We mostly use the Cloud - I'm seriously pissed off with Western Digital for not keeping their drivers up-to-date. Imagine selling something that's intended for archiving, but allowing the device drivers to become obsolete.

Re: using SSD for TimeMachine backup
I have replaced a TimeCapsule’s HDD with an SSD, and directly hooked up an SSD to a Mac for use as a TimeMachine drive. I get the argument that SSD “writes” will slow down after it’s filled, but not really seeing the numbers yet to show, after the SSD has slowed down, whether it would still be faster than an HDD.
BTW, anyone here has old TimeCapsule (the version that looks like a tall column) for sale? Apple Inc. discontinued that product line but I still like them as TimeMachine backup drives. And since I can replace the HDD myself, I figure I can still make use of TimeCapsules that still function OK except the HDD is shot. :man-shrugging:

Notice that “play” and “stop” are two separate buttons.
Modern UI designs have mostly combined the two into one button. -

Interesting. I have a regular hard drive that I use for Time machine.
I think I should do what you do George and have back up to that one and keep the backup "off site" and then every so often, switch them out.
