Which types of 8.5 GB DVDs do you recommend?

[leonardevens]

I've been using CDs and 4.5 GB DVDs to record large format camera images, but now I find I need to use larger size DVDs for that purpose.

I had a few Office Depot DVD+R DL DVDs which record at 2.4 X, but I now need to order faster recording ones.

My computer and DVD drive are relatively new having been purchased in the last wo years.

What considerations should I consider in choosing these DVDs with respect to speed, quality, etc?

Any recommended brands?

I've been buying DVDs from retail stores such as Office Depot or Microcenter. Is there any potential problem in having such media shipped from Aamazon or another Internet provider?

I store my image directories on a large external USB drive, but I need the DVDs for "permanent" backup.

In principle, I would like my children, grandchildren, and descendants doown the line to have these images.
