What's your opinion on using rw Blu-ray disks for storing movies, ect? (lemmy.dbzer0.com)

Well I thought about using them instead of buying a hdd, I looked for some comparisons and found a 50 pack of 25gb blu ray drives and a 2tb harddrive for 60, it can store 35 movies more (thinking the movie is 24 GB) than the pack of drives, and that isn't accounting the disk drive to read the disks (Keep in mind these are just the first results on Google for me)

In my opinion the blu ray drives are more fun to use than clicking a file on a computer, but the storage payoff is huge

What is your opinion on this?

PS: I'm definitely buying the hdd instead

Blu-ray isn't really rewritable (at least, not in the same way as a hard drive). You can add to it incrementally and erase everything once, after which it becomes a normal disc. So ultimately, it's one-directional writing.

But my biggest problem with CDs (of which Blu-ray is a type), is that they are only as good as both the reader and the physical storage method. Want to watch a movie? Maybe the player's laser has dust on it (or worse, a scratch). Maybe the motor has a short. Maybe your disc has a scratch in just the right place to make it unreadable by the player.

There's just a lot more points of failure, even if you wanted to go that route.

You're thinking of BD-R: BD-RE can be rewritten/erased hundreds of times

And as people are starting to find with old cheap CDs, they have a shelf life and just degrade after a certain amount of time. That time may be decades away, but depending on your use case it's worth consideration.
