What @buggybuggy is trying to say makes sense. If not now it is relevant for years to come. I backed up all my digital photos from 2005 and scanned photos from the 90s in DVDs that I thought were cheap. I bought a stack of Sony DVDs and thought it is a good option for lifelong storage - a single 4.7 GB DVD costed Rs. 20. Much cheaper than HDDs or SSDs before 2015. Although they are affordable now, I don't know if I can still plug in my drive after 10 years and use it with no issues. Heck you would have to find a USB-C to USB-A connector for that. Now retrieving all the stuff from those DVDs is not an easy thing to do as I don't find a disk reader. I might do it any sooner as I fear those disks might be corrupted. Cold storage is a good option for stuff like photos and other unimportant files as the pricing might come down in a long run. Media compression is evolving and with faster connections we can have quick access to it in the future.
