i had flash drives with read errors after less than 7 months of no power.

That explains a lot!!! Thanks

SSD/flash drives [...] have a lifespan of no longer than 2 years if they are not turned on periodically.

What, really?!?!

I could buy a 25 GB BD for 0,44€.

sheesh, I wish, I actually never considered BD for storage and today was the first time I saw a pack of BD for sale because I had to search for it LOL

Why are high capacity Blu-rays so much more expensive, especially compared to HDDs or SSDs where the price per GB/TB usually drops with higher capacity?

I believe it's because of the density? the space is the same but you have to store way more

Where I live I can't even get a 4TB one for that price

I hate my country
