It just seemed like yesterday when I’d back up my data to 1 CD (that is about 0.7 GB). Yes, this was before I got my first digital camera and my TV card, so I didn’t have that much data.
Now I used DVDs. Specifically single-layer, single sided. They hold about 4.7 GB.
I must admit to wondering (okay, worrying) about the durability of those old CD back ups. What if the media fails? So recently I’ve started consolidating the old CD backups onto DVDs.
It’s about 6:1, I can squash 6 CDs onto 1 DVD.
And so to Blu-Ray. The smallest capacity (single sided, single layer) Blu-Ray disk is 25 GB. So I can further consolidate; copy my DVD back ups onto Blu-Ray. Once I get a burner 🙂
The ratio is a pleasant 5:1. So, 5 DVDs onto 1 Blu-Ray disk. Or, if you do the maths, 30 CDs.
So, all of my old data backup CDs can easily fit on the smallest Blu-Ray.
