Please clarify, are you saying that 2TB of of blank Blu-Ray discs are 35% cheaper than 2TB of external HDD storage? Unless prices in Europe are way different than in the U.S., your price comparison seems to be off.
I made a comparison of optical disc storage vs HDD storage back in 2016 and calculated costs of $33.20/TB for Blu-Ray (40 discs @ $0.83) vs $35/TB for HDD (external or internal). A quick price check on Verbatim Blu-Ray blanks shows them to still be ~$0.83/disc and 2TB portable external HHDs are still around $35/TB.
Yes, 3.5" 2TB external HHDs are hard to find, but jump to 3TB+ drives and you're looking at less than $35/TB, as low as <$20/TB when you get to 8TB.

O.K i was just looking for seagate and WD discs. And yes, it is 35% cheaper to buy 2TB in BD discs here. Also notice when you bought bigger package, not 10 but 25 pack you get even lower. And I'm also sure you are right about bigger HDD are cheaper, 3TB HDD but still 25 dollars for cheaper buy BDs. And has to say it is far cheapest seagate, wouldn't bet at this HDD too much.
Edit: the problem seems to be dollar is now 3/4 what used to be, and they forgot to get hdd prices down. It is quite common, seems to me. On other hand BD are still same so.

I use BDR for my cold storage backup, so would pretty much only go to them if my main file store (RAID array) failed*, and the relevant USB hard drive (because of fiddliness of recovering off 10/100s of optical disks, USB hard drives are my first line of backup) also failed. I have just over 400 burned disks stored out of the house as my backup fallback. Here in NZ the the local availability of media is terrible, and we are at the tail end of the international supply chain, so I use 50GB disks and import them myself. What I lose in the extra per-GB disk cost is easily offset by the shipping savings from reduced spindle count. Plus, it saves a bit on storage space.
* Unless I needed a movie etc that I figured I would never want again and had deleted from the main server to free up space. I burn batches of files to BDR as I transfer them to the server. Since the disks are write-once, files stick around after they are purged from the main array.

No, i don't compared LTH, only HTL that never failed at my side (just some Verbatim DL). LTH are not more sold I hope. And yes, I'm sure compared HTL.
So pricing strategy in my country is bit different than in overseas areas.
Going back to my original question on what DVDs are more reliable.
These are the types we can get here in Brazil. I'm not sure if they are their cheap bad quality variety.
In a few months I may be able to buy a better type in Argentina, byt I wonder what type these ones I show are.
