I’ve been looking into BD-Rs for long-term data backup, but I’m finding a lot of mixed information on whether current Blu-ray discs are HTL or LTH. There seem to be conflicting claims, and I want to clear things up:

• This post claims HTL BD-Rs are almost nonexistent now (with the exception of M-Discs): link to post.
• On the other hand, in another discussion, some users say that LTH discs generally don’t exceed 25GB capacity and are rare even at that size: link to post.

I’m looking to purchase BD-Rs to back up my data, but I’m not sure if they’re HTL or LTH, and there’s no mention of the type on the product page.

Does anyone have recent info on the availability of HTL/LTH BD-Rs, or tips on how to identify which type I’m buying?
