DVD+RW or DVD+R for long term storage

I would like to archive some data for at least 15 years and I wonder which of DVD+RW or DVD+R would be most reliable. Please indicate why one format over the other would be better.

Thanks.

Neither is really “proven” for archiving. But RW is clearly the wrong choice.

Why do you suggest that DVD+RW is the wrong choice?

The clue is in the name, it’s erasable. “Phase change”, and that’s exactly what it does over time, it “un-records” itself.

I believe so.
But what would be good enough for archiving then?

a cheap hdd :slight_smile:

I am using a brand new hard disk also for archival purposes. I wonder if it needs to be “spun-up” every now and then to keep the bearings from sticking into position.

Does anyone have any advice, hints or suggestions on the best storage/maintenance procedures for hard disks that are being unused for years with important data for archival purposes?
