Verbatim 43615 BD-RE 25GB/2X Blu-ray - 5 Pack Jewel Case

I was dithering which brand to buy to use with my Panasonic hard drive TV recorder and in the absence of Panasonic's own brand (I can't find those anywhere) decided to try these. I haven't had any failures yet and that is what matters for archival purposes. I have also started to use them with a Pioneer external disc writer and they seem very stable with that, too. I wouldn't waste money trying a lesser brand. These do seem to work very well.

Ok, so you'll need a blu-ray burner to burn / read these discs. But that said...They are great for data backup storage. They say there are two kinds of people - those who have haven't yet experienced data loss, and those who have. External hard drives can fail, whether solid state or disc based. So I like to back up important family movies, memories etc on something else as well, and blu-ray discs are a great option.These ones can store up to 50GB each, so enough for tons and tons of photos (my entire back catalogue in fact, and that's quite a few from years of travelling). They can also hold lots of .mov files, great for family videos etc.Longevity, I'm not sure. Too soon to say. We were told back in the 80s that CDs were indestructible. It turned out they weren't. If these last me 10 or 20 years, with care, I'll be happy, I'll have made new copies by then, assuming I'm still around to do so! I don't much mind if they outlast me, or not. I looked into it and did a bit of research to see how long we can expect DVDs or BLU-Ray discs to last. The answer turns out to be "long enough for most purposes, but not as long as we thought"!If anyone needs to archive really important material for future generations, they might wish to use the highly stable and reliable MABL-discs. These have passed rigorous quality controls and are supposed to last 1,000 years (assuming they're kept carefully in good conditions). My understanding is that Verbatim's BluRay discs were 'MABL' though it's not clear to me if this set of discs are.

I was wondering if these were LTH (worse) vs HTL (better) but it was not officially mentioned anywhere. The underlying surface colour is blue-ish grey, which usually indicates an HTL disc. ImgBurn reports them as "Recorded Mark Polarity: HTL" and the Blu-ray Disc Association website also reports them as HTL by providing the disc manufacturer and media id "CMCMAG-BA5".This means that these discs are excellent value for money from a renowned brand!

Brought these to store a large amount of video and picture files. They are designed so that you can print onto the disc, but can still easily be written on as needed. The discs themselves seem to be well made and don't appear to be any more flimsy than other brands I have used in the past. I have stored and transferred data to them with no issues so far. In terms of longevity, then this is only proven by many years of storage, which is somewhat open to interpretation (as they still use an organic material). M-disc, which is more expensive is the only type of disc that professes to last many generations long (theoretically 1000 years), but I have written onto (cheap) CDs approaching 20 years old that still work fine, but they are stored in a metal box away from light and indoors (so no extreme temperatures), so make of that what you will, as to if you trust storage via this medium or not. Otherwise happy with the cost to quantify to storage ratio of these.

Used for making 3d videos. Absolutely no problems, and no coasters

Bought these discs to back up files etc. and used my 2012 Pioneer BDR-206DBK Blu-Ray Recorder to do the writing. I've had no issues so far, they seem good Discs and I haven't had any coasters at all. As for longevity, I cant comment - only time will tell. As with any Blu-Ray disc, I would advocate handling them with care and avoid getting finger marks, grease or dirt etc on the surface of the disc as it will make them difficult to read for any reader; I always grip discs on the very outer edge and/or wear gloves to alleviate the possibility of causing issues relating to reading the disc.I know its stating the obvious but, you'd be amazed how many people think discs are indestructible !!!! LOL!!!

Fantastic discs, make sure your writer is working correctly and you have the latest bios and drivers for it, plenty of people that complain about poor media simply haven't got their set-up right, if you value your data just buy a brand new blu ray writer when you buy the discs, my old drive had hardly been used but was having problems so I bought a new pioneer drive on here with the discs.Use the latest version of Nero, it has something called discspan this lets you drag a massive folder over to the disc and it will automatically split the files on to the discs for you then all you have to do is put a new disc in, on 4 speed this takes approx 35 mins to burn and verify the discs, make sure you switch on verify data as this is important to know that the discs are being written correctly.I have burned 50 of these discs backing up my various digital camera and music files with no coasters.
