The $/TiB storage cost currently creates weird choices in backup media... even making some older media formats economical again. Just finished a consumer storage option survey yesterday.
Even if you account for consumer drive+spare cost, a 8TB HDD is still the best JBOD option. For under several dozen 25GB projects, the BD-R disc drive is currently the cheapest media backup option (about 35% cheaper than HDD above 12TiB). Note 50G and 100G BD EOL media are actually equal to or a worse deal than HDD.
Also, HPE LTO9 18GB Tapes are currently around 5 to 15 times cheaper than HDD and SSD in terms of data storage cost, but the fixed cost of tape auto-loaders and drives don't always make sense until you have a significant amount of backup data. Tapes may also create a single point of failure in use... so incremental backups are a non-zero risk, and triple redundant hardware is required (old hardware gets hard to find.)
The classic joke is still true: "Fast, cheap, or good.. choose any two..."
I looked in to the bluray thing and concluded it just doesn't make sense at any level. You have to buy a bluray writer which will become increasingly rare, and then you are limited to 25GB disks where you have to factor in a chunk of that will go unused as each project won't fit on exactly 25gb.
For the effort you are expending, just getting a hard drive makes way more sense even if the $/gb is technically a little worse. The utility of hard drives is much better.

I mostly agree, but the 25GB M-Disc EOL media format is fairly interesting for archival purposes. The gamble actually made sense in this rare instance as each active project folder still fit on one disc, and the $120USD omnidrive firmware drives should keep the retro-equipment running for a few more years. These are relatively inexpensive even with a spare unit in the box.

In many cases this can be true, but the 3 years of HDD flight time compared to the 7+ year SSD wear life is also fairly close. It is weird, but the cost of higher capacity 18TB/24TB HDD also no longer make sense for JBOD either... unless you are hitting rack space constraints. =3
AWS is an option up to 30TiB, but also feeds into the over-provisioned data-center market pressures. The recent "rclone --gui" solution does bestow rsync/sshfs like features for Windows users now, and remote mounts are easier/cleaner to bring up. =3
