M DISC BDXL 100GB 6X with Branded Surface – 5pk Jewel Case Box

I bought Verbatim M-disc for the first time to back up my extracted movie Blu-ray ISO. I was worried that it would fail when burning the disc after reading reviews online, but with the right software and a good burner, this disc is very reliable.I bought 25 spindles of 25GB SL discs, and 25 out of 25 discs were burned normally without any errors! Wow!The quality of Verbatim BD-R is undoubtedly good... but the price of M-disc Blu-ray seems a bit too expensive IMO.In the old days of DVD, organic dyes were used, so M-Disc had the advantage of using inorganic dyes to enhance the durability of preservation, but most Blu-ray discs, except for LTH discs, are manufactured using the HTL method that uses inorganic dyes same as M-Disc. Unlike DVD, the M-Disc BD-R discs doesn't require any specific burner and fully compatible with normal bluray recorder. Base on these facts, I don't think the difference between the M-Disc bluray and "normal" HTL bluray discs is big in terms of durability.The price of 25 M-Discs BD 25GB is $65. On the other hand, the price of 25 25GB HTL "Inorganic Dye" BDs manufactured by the same company is $23, while Amazon Japan sells 50 discs for the same price!If there is not much difference between M-Disc and regular HTL, there is no reason for Verbatim to maintain the production line for this disc after Millineta, the creator of this format, went bankrupt, but even considering that, I think the price difference between the two is too much.Of course, I think the quality of the Verbatim discs themselves has been proven this time, so I plan to buy Verbatim Blu-rays again next time (in fact, as of the time of writing this review, the Verbatim discs I ordered from Amazon Japan are already on their way!)Maybe in a few years, I will write a second review of M-Disc and advise you not to repeat the same "mistake" I made just now. Who knows? Only time will tell.For those who want detailed information...The software I used to burn my disc is ImgBurn and I burnt all my discs with 4x speed.All the discs I burnt are verified after the writing is finished.The disc burner I used is LG WH16NS40 with external enclosure (Vantec NST-536S3-BK)I also attach photos of the discs before and after recording.

Great price! I tested it with a Verbatim M-Disc 25GB Blu-ray and successfully burned 25GB in just 30 minutes. Highly recommended.Note: The USB passthrough includes three USB 2.0 ports and one USB 3.0 port.

I closely followed the invention and introduction of M-Discs, because, perhaps foolishly, I wanted my family pictures and videos to last forever. Or at least a long time. Archiving anything digital now days is a huge problem. You have a bunch of choices, not all of them good. It's not like the old days where black and white photos from grandpa's photo albums or Kodachrome movies stuck into a closet could be pulled out 50 years later, and there's a good chance you'll still have an image.If you put your digital media on a hard drive and stick it on a shelf, the drive could easily seize up if you pull it out 10 years later. Flash drives are just as bad. You may not have anything after 10 years. The cloud? Now somebody has to pay the bills. What happens when environmentalists figure out all those data farms are a huge source of CO2? Or your grandchildren decide not to pay the Cloud monthly payments? Your digital memories are toast.So along comes M-Discs, which have a completely different formulation than standard organic dye blanks. The Navy allegedly compared M-discs to ordinary blanks by putting them out in the sun and rain. Data on M-discs survived a month of abuse. The other discs? The data was gone. Great. You can stick M-discs on a shelf and they'll be fine in 50 years because they say they last 1000 years.But wait! Will anybody have the players functioning? Look how fast storage technology is changing. Can you get grandpa's 8mm movie projector to work? Does your car still have an 8-track tape player? That's the problem. And to add to the confusion, supposedly some French Technology agency did another test of M-discs vs. "ordinary" archival blanks, and found they were all about the same, and that a little abuse made the data vanish. A completely different outcome from the earlier Navy tests. All these presents a real dilemma.I've rolled the dice and still use M-discs. I put warnings all over the labels I make to keep the discs out of the sun and hot attics, and to occasionally review technology options in case media needs to be transferred to new "better" storage mediums. You really just have to trust that somebody down the road cares about the past, and if they don't the good thing is YOU won't be around to care either. For medium term storage M-discs are great. You have your data, your privacy, and some level of extra durability. The NSA and the North Koreans aren't culling through your digits in the cloud, and thinking about erasing them. However, remember. Your house can burn down. Make an extra disk and store it elsewhere. Preferably out of a flood, fire and earthquake zone.They cost quite a bit more than ordinary blank discs, but I've never had one fade out like the ordinary organic disks have faded. And I also back things up on hard drives just in case. Multi-site and multi technology storage is about all you can do to keep your stuff for a while.

Excellent back up media. Supposedly a 100 life expectation. Lots of space for your huge files.

One of the discs was defective, and you could see there was a mess up with the data layer. I would’ve taken a photo, but I threw it away. The second disc I tried worked with my drive. Time will tell how long the disc will remain usable.
