Verbatim M DISC BD-R 25GB 4X Lifetime Archival White Inkjet Hub Printable Blank Blu-Ray Recordable Media – 10pk Spindle

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.

So my goal. I have about 90 gigs of data (files like word, excel, pdf etc) for my business that I wanted to backup to a single disc and then store the disc offsite in case of fire. I wanted to be able to stick the disc into any computer and read the files with out having to load software to read the disc. I have the LG BD-RE BU20N slim drive in my HP i7 sff desktop. I also wanted the disc to be permanent meaning you couldn't change it after it was burnt.I put all my files into a single directory on my pc which has an SSD for storage. I then put the disc in the drive (Windows 10 OS) and chose "With a CD/DVD player" (Mastered) as opposed to "Like a USB Drive" which allows changes after the files are burnt. I then copied all the files onto the disc. It had to fix a few names because they weren't compatible with the CD burning standard. After about 10 mins I was ready to click the burn button. I clicked it and after about 5 seconds I get an error saying it didn't work and the disc is probably not usable. $17 coaster.Now I have been burning discs since the original single layer CD media came out and back then we made a lot of coasters with buffer under-runs etc. So the first thing I did was check the firmware of my drive. It was 1.00 but there has never been any newer firmware. I happened to have 25gb Verbatum M-Discs also so I broke my 90 gb into 4 25gb chunks and those 4 discs burnt just fine.So I went back and tried it again.....5 seconds another $17 coaster. I figured maybe it was the drive which they don't make this model anymore. LG and Pioneer seem to be the two types of drives you can get so I ordered a full height ASUS external drive which has the Pioneer mechanism in it. Tried to burn with that drive...5 seconds later $17 coaster. The Asus drive came with software so I loaded that software. Now that software made it's own proprietary 90gb which means I would have to use that software to read the disc but at this point I wanted to see if I could get anything burnt on a 100gb drive. After about 30 mins of processing the file and about 10 mins of actual write time...another $17 coaster.Now I only had one disc left at this point. I figured what the heck. I put it in and this time I chose "Like a USB Drive". It prepped the disc. I then started to copy files to the disc and about 6 hours later I had a fully loaded disc. I could then read that disc in any computer that is Windows XP or newer. Only downside is you can change the disc. Someone could delete all the files. Ofcourse this is BD-R so you don't get the space back and technically all the files are still there just the FAT table has been modified but still it's annoying.For now I can live with the Life File System version of the disc. I was able to add files to the disc using either the LG BD-RE BU20N drive or the Asus BW-16D1X-U 16x External Blu-ray so both drives will work with this media.So if your doing what I was doing....choose "Like a USB Drive" not "With a CD/DVD player" and you will probably be successful also.
