I just posted the article French research: Avoid Blu-ray LTH discs for data archival.

If you store data on recordable discs, then you should read this.

Well, the problem is two fold… (reason #1) there are virrtually no HTL blue ray discs being sold due to the ultra high cost… (reason #2)… without volume sales, HTL will never take off-- for further detail see reason #1.

If I had my choice to buy HTL discs at current prices or a cheap hard drive as backup-- I’d buy the extra hard drive… HTL needs to become LOW priced!!!

Most of us enthusiasts would probably pay the “VERBATIM AZO” % premium that are attached to those discs for HTL blue rays, but the literally sky high pricing keeps them out of the hands of people who WOULD use them for archival… and that’s a damned shame!

Hey Domi, thank you for bringing this to the front :flower:

Judging by our members’ posts, there are quite a lot of people buying HTL BD-R. In the US, HTL BD-R are by far the cheapest available. The situation is a bit different in other countries, where LTH can be among the cheapest.

Some of us will undoubtedly continue to use optical media as a second or third tier for archival storage. And we are most certainly anxious for any news on their longevity.

@tmc8080: I don’t think that you’re keeping up with BD-R prices. Currently you can get those long lasting Panasonic BD-R for $.07/GB, making the price per GB lower than HDD and an attractive option. Far lower than the $.33/GB cost of archival grade DVD-R. In fact you’re getting 1TB of high quality BD-R for $70.00. Looks darn good to me. And the advantage of reduced shelf space required by BD-R vs DVD-R just sweetens the deal.

I use verbatim’s. When I was looking around the last time i bought some (6 months ago?) the LTH’s were about $25 for a 20pack and the HTL’s were about $33 for a 25 pack. I paid the little bit extra and went for the HTL’s.

I hadn’t really read anything good about LTH discs. I did use one pack of them when I first got my bluray burner, then switched because the price difference wasn’t that much.

I still use optical for backup purposes though. Mostly because I’ve generally chosen quality discs. Which means stuff I’ve burned from the 90s still seems readable. I still trust optical media more then hard drives. If a hard drive dies you loose so much stuff. If a few discs become unreadable you lose some stuff.

The prices for HDD’s have obviously fluctuated… the PRE FLOOD street price for a 1tb hard drive was as LOW as $50… now you can only find 500gb hard drives around this price range… people forgot this price range… while blu rays were about $1 per disc or 4 cents per gb… and I believe at the time, HTL discs were about double… or $2 per disc / 8 cents per gb… (new prices range to 4c - 5c/gb to 5-10c for HTL). so hard drives WERE a better deal… which stunted blu ray use for archival backup. Eventually the lines will cross again and HDD capcity will be cheaper than discs. There are very few makers of HTL discs… Verbatim doesn’t clearly push HTL discs.

I think I’d trust a decent hard drive for 5 years of use over 40 blu ray LTH discs. The inorganic dyes ued in HTL haven’t been in use long eneough to determine their actual longevity. Maybe another 2-4 years could tell more if consumers buy more HTL, which they haven’t yet.

I am still stumped by your perception that HTL BD-R are in the minority? This must be influenced by your location? The numbers of HTL being produced by manufacturers has far outnumbered the LTH being produced by TY and Verbatim. All the earliest 2006-2008 BD-R were HTL, LTH did not come around till 2008. A quick look at online E-tailers such as Supermediastore shows best-sellers as overwhelmingly HTL.
