It would be good to find a practical place other than a safe deposit box to store the drives if being able to gain access to them immediately after your death is important to you. Depending on the situation, gaining immediate access can become dicey.
Each month I put some external SSDs with my important data files and photo files into my safe deposit box and I bring home the ones which have been living in there for the past month. Needless to say, COVID-19 really screwed up my usual system for quite a while but now at least for the moment, we're back on track as I have access to my box whenever I feel the need to get to it.
Being able to gain access to my photo files or my data files after my death -- well, since I will be DEAD that won't matter a flying fig to me, then, will it? Certain important data I also have made available in a print format which would be available to my heirs fairly soon after my death. I actually suspect that my photo files and most of the data files really won't be of interest to my heirs anyway, and that they'll do with them as they choose.....which probably means looking at them maybe once and then wiping the drives to use for their own current purposes. Fine with me..... For now, while I'm alive and kicking and shooting, I want to have backups of my files that are important to me available in several ways, including in offsite locations. I don't have the luxury of family or trusted friends living close enough by that it would be convenient to stash some of my external SSDs in their homes, nor do I have a desk drawer in an office at work, since I am retired.
Whatever happens with my stuff after I'm gone will no longer be my concern. Since my remaining small family isn't all that close anyway, I don't anticipate a lot of interest in much of my stuff, especially the photos. I'm not a prize-winning photojournalist or someone who has put out best-selling photograph-laden "coffee-table" books. While I am of course interested in what I shoot I am not harboring any illusions that anyone else is or would be.
The younger generation has their own concerns, own priorities, own focus on life. That said, though, yes, older family photographs are still readily available in various photograph albums lovingly put together by those who came before me and a few by me as well, and I'm sure that those will be cherished by my heirs. They aren't going to give a darn about my photos of Alfred, the Great Blue Heron or the Hooded Mergansers -- they'll be more interested in photos of themselves as children with their parents and grandparents, etc.
