Verbatim M DISC BD-R 25GB 4X Archival Blu-ray Recordable Discs, 25 Pack

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.

I purchased this to burn 89GB of data files (mostly docs, xls, ppts, pictures, Downloaded programs, and lots of GPS data/image files/maps, and a few home movies--collected since the 80s). .

I initially bought a LG Electronics 8X USB 2.0 with M-Disk $27.25 (Super Multi Ultra Slim Portable DVD+/-RW External Drive with M-DISC Support GP65NW60). This burner was NOT recognized by either of my 2 computers as BDLX - M-Disk (3TL) compatible. None of my burning software (Nero, Power2Go, LenovoBurn, and 2 freeware programs) would recognize this as M-Disk compatible either. This was useless for Blu Ray, with my computers. . So, I purchased the 2016 NERO Classic and this LG 14X USB3.0 burner. I Really wanted to make an Archival backup (you can get info on why M-Disks are so valuable for almost permanent/lifetime Data storage on the M-Disk website). . This burner was immediately recognized by my computer as M-Disk BDXL compatible. I put in the Verbatim 100GB BDLX Disk and stepped through the proper process to span unbroken files (See Nero Burning for M-Disks on the M-Disk website for the correct settings. Amazon will not allow a link, but it's under Step-by-Step Instructions - a downloadable PDF). . It ran flawlessly. It verified the data flawlessly. It burned 89GB of mixed data and verified it in 58 minutes. I was utterly impressed. I viewed some of the more complex data files directly from the finished disk and they were perfect. . This combination worked better than I had hoped for (Nero Classic + this Blu Ray M-Disk burner) and was worth every penny. Notes: I tried some of the freeware for burning, but they do NOT have the Ultra buffer (in Nero's program) that seemed to make this process run flawlessly. I was pleased I purchased the Nero Software for this task.

I've always been concerned about exactly HOW LONG data could be stored over the years. Mag tape definitely isn't it, nor is data stored on SSD drives, etc., nor 'paper'....really! Come on! Not likely. Well, if you maintain a CD drive that can record & playback these 100Gb disks then THIS might just be what you are searching for. I finally did get one that seems to work well, after an earlier failure, and am in the process of testing it out. It seems to work well, with only a couple of minor hesitations during playback, but I think that's not an error, just the fact that it's mechanical and probably subject to such things occasionally with very large files-- I'm continuing testing and proving to myself how reliable it will be. The lifetime prospect (storage) for this type of media is way better than what I used before, despite the slower record time and greater cost. Something to work out later, I suppose. OK -- this 'later', and I got some blank BDXL Verbatim disks.....I experimented on the 1st one and was VERY happy with the quality, however the 'but' part of the testing is a 2-parter......Number 1 is the COST per disk is high, and since I'm sure you can't re-record over, you better not waste it.....the 2nd one is a killer, and it was SO slow recording you almost have to start the copy when you go to bed, because by the time it's done (91 Giga bytes writable space) it'll be next morning anyway. Probably minimum of 5-7 hours per disk. However, IF it works out to be the 'longest' storage capability, then so be it. It STILL works good.

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.

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.

Good M-discs. Just wish they weren't going the way of the dinosaur.

Edit9: now two more have failed and I will never be using mdisk ever again, I gave it a second chance for awhile and it failed me so therefore there is jo reason to continue waisting my money and my time on something that clearly isn't made right anymore. Edit 8: so far my latest purchase of the 5 disk has had 1 of the 5 disks failed with 3 that succeeded but the 1 disk I only tried copying 35gb and it failed. Edit 7: Even the pack from I gt from another place had size problem I now know it is the companies disk the size won't burn between 62-65gb, these disks are no longer advertised properly so if you are after 100gb you should look elsewhere or expect to buy many more due to the low size it can burn, Is this even legal at this point I really don't know but yeah the size is not even close to accurate. Very Disappointed and hoping they came up the GB on the stone on the disks. Edit 6: From 2 stars to 1 star and a 0 if I could as my latest 5 pack 2 disks so far have not been able to hold more than about 62gb and between 62gb-65gb they fail to complete backup of my data, this isn't the first time this has happened but I can tell they have completely gone to this size with all their batches now as even the singles I bought just recently had the same problem and I am not able to get anywhere close to 500gb I mean what is 62x5 not very much I believe it is 300 something and I have no doubt in my mind the next 3 will be the same, so anyhow I have like no desire to buy this anymore and am going to just stick with buying microsd cards and hdd drives for the future for preservation because this is a joke and I can't even tell if these disks are real m-disks or not so who knows if they end up failing for long term storage plus M disk 100gb drives that actually work for these there is less brand names available than like 2-4 years ago as most are out of stock and aren't returning back to stock such as my M-disk vertamin that has the high quality drive that they changed to a lower quality drive now I heard and the other name brand ones are selling worse quality drives as well I heard from reviews and word of mouth. I don't exist to buy low quality stuff and when quality gets bad I move onto something else and don't put up with this. Edit5: On edit 3 below I noticed the space problems I was having was due to to using a compression tool which the space smaller on drives but not on the disk, ai figured it would carry over with that same space to the m disk but it didn't so long story short I was wrong these disks do hold about 92gb of stuff as I tried it again without compression and the space on each disk since has been able to hold about 92gb-93gb of stuff. This right now is worth it as hdd and ssd and micro sd cards and so forth are going up in price so right now I would say buying a bdxl m disk blue ray external drive is worth it especially knowing these disks will last hundreds upon hundreds of years. By the way the disks are still the same since I started buying them which was what over a year ago now if I am not mistaken so yeah you can still crack it with a hammer and it will still work as long as you don't split it anywhere, the disk is amazing and all of my disks still work and can copy data on it to my computer anytime I need to such as if I forgot I deleted something off my hdd and programs that find data don't find it or if the hdd ssd or so forth got corrupted well this is your solution as it is a write once disk and it also is impossible for it to become corrupted so whatever is on the disk is put onto this stone disk and locked in time until you access it, m disks are truly amazing I gotta admit :). Edit 4: Now for only 1 disk it is not worth what they are asking, better look elsewhere Edit 3: The latest disks now struggle to copy around 74gb of data. I no longer recommend this Edit 2: these only allow around 92gb of space I haven't figured out the exact amount but have kept it under 94gb on each disk and it gives the okay on the space left but trying to do around 94-95 or so gb says not enough space, this is a very minor letdown but I figured I would mention it so future buyers would know. I will be taking away 1 star now because the ones I bought the very first time allowed me to copy 100gb of data so the company must have reduced the size on the discs sadly as that is all I can come to the conclusion of plus they still advertise them as 100gb and yet they are not but thankfully I probably won't ever need more of these after the ones I just ordered so it won't be a problem in my future. Edit 1: Forgot to mention I used it on Windows 11 with Verbatim drive and Ashampoo Burning Studio 26 with no problems, newer version will work to such as the newest 27 version (burned more than 8 discs so far with zero failures). Just make sure it is a drive that supports bdxl m disks and bdxl is only for 100gb disks, any lower such as 50gb are bd-r so as long as the drive says bdxl m disk support you are good, took me awhile of researching to wrap my head around this so this another thing I wanted to help future people out with :). Old: Still works even if you use a flat head screw driver and use the corner pointy edge and shred the disk, I tested it on one to see how strong these things are so I can have proof that they truly are legit and sure enough they are :). Every single disk has been error free and flawless btw.

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.

Alle Scheiben fehlerfrei auf Pioneer-Laufwerk gebrannt. Ob diese Scheiben wirklich 100 Jahre Lebensdauer haben werde ich nicht mehr feststellen können...

Ich brenne schon seit 1996 optische Medien, damals noch CD-R's in Zeiten, wo man sich regelmäßig über mit regelmäßigen "Buffer Underruns" rumärgern mußte, ganz besonders wenn so ein Rohling schonmal 15-20 DM (ca. 10€ pro Rohling) kostete. Und ich habe in den nunmehr 24 Jahren sehr viel Erfahrung über optische Medien gesammelt und sehr viel Mist bzw. Beiträge mit Halbwissen gelesen. Die Entwicklung der brennbaren Medien wie CD-R's, DVD-R's und BD-R's war anfangs stets von hoher Qualität geprägt, welche aber aufgrund der hohen Konkurrenz auf dem Mark immer weiter nachließ. Heute sind die optischen Datenträgern aufgrund des extrem schnellen Preisverfalls und Größenzuwachs von Flash-Speichermedien wie SD-Karten oder SSD's kaum noch von Bedeutung und somit eigentlich nur noch für die Nutzung auf älteren Geräten oder die Archivierung von Daten interessant. Ein großes Problem dabei ist die Haltbarkeit von über 95% der jetzt noch auf dem Markt angebotenen Produkte, insbesondere Supermarkt-Ware, die solche Disks im 10er Pack oder als Spindel umgerechnet für nur noch wenige Cent-Beträge pro Rohling anbietet. Nahezu alle Rohlinge dieser Art überschreiten selbst unter normalen Bedingungen nichtmal mehr die 5-Jahres Marke, was den optischen Medien in den letzten Jahren zu unrecht einen sehr schlechten Ruf verschafft hat (meine ersten DVD-Rohlinge von "Verbatim", die einst von "Taiyo Yuden" hergestellt wurden laufen heute noch nach über 15 Jahren wie am ersten Tag und zeigen beim Qualitäts-Check nur wenige PIE- oder PIF-Fehler). Umso überraschter war ich nach dem Test dieser M-Disc, die ich nun schon seit einigen Jahren benutze und bisher noch keinen einzigen Ausfall hatte. Die Idee, die bislang verwendete organische Farbschicht durch nicht verfallbares Material - einer Gesteinsschicht - zu ersetzen machte mich sofort neugierig, zumal das Archivieren von selbst gedrehten Filmen, Fotos, Audioaufnahmen und sonstigen wichtigen persönlichen Daten für mich das A und O der Datenspeicherung ist. Leider gibt es auch hier an verschiedenen Stellen und in zahlreichen Rezensionen viele Fehlinformationen und Halbwissen, dem man einfach mal entgegenwirken muß. Zum einen beruhen die meisten Probleme wie Inkompatibilitäten oder Brennfehler darauf, das viele Käufer sich einfach nicht die Kompatibilitätsliste oder Systemvoraussetzungen durchlesen. So sollte mittlerweile jeder wissen, das man zum Brennen von M-Disc DVD's einen geeigneten Brenner mit entsprechend starkem Laser braucht, sowie einen Brenner, der die entsprechenden Medien auch korrekt erkennt und sie entsprechend auf der Webseite des Herstellers aufgelistet hat (hier kann ich die Geräte von "Pioneer" nur sehr empfehlen). Zum anderen halten sich einige Nutzer partou nicht an die empfohlene Brenngeschwindigkeit, denn was viele nicht wissen: Je langsamer die Brenngeschwindigkeit der zulässigen Spezifikation, desto besser das Brennergebnis und desto geringer die Fehlerquote des jeweiligen Rohlings = noch längere Haltbarkeit. So liefert selbst ein geeigneter Brenner mit hoher Brennqualität und Geschwindigkeit (z.B. Pioneer oder LG) bei 4-facher Brenngeschwindigkeit ein besseres Ergebnis, als wenn mit 16facher Geschwindigkeit gebrannt wird. Da die M-Disc ohnehin aufgrund ihrer Eigenschaften nur mit 2- oder 4-facher Geschwindigkeit gebrannt werden kann, empfielt sich hier also die 2-fache Brenngeschwindigkeit. Zusammen mit einem geeigneten Brennprogramm sollte man so schon 99% der hier zu lesenden Probleme einiger Kunden aus dem Weg gehen. Ich empfehle hierfür das kostenlose und nur ein paar Megabyte große Programm "IMGBURN", welches die meisten wichtigen Backup-Funktionen bietet und auch mit aktuellen Brennern zurecht kommt, auch mit Windows 10. Zwar ist es nicht ganz so kompfortabel zu bedienen, wie so manch andere aufgeblähte Software, dafür brennt es aber zuverlässig, ist recht simpel aufgebaut und bietet obendrei noch eine Verify-Funktion. Die hier verwendeten M-Discs wurden stets mit höchster Qualität gebrannt und sollten länger halten als jeder anderer Datenträger, sofern man ordentlich damit umgeht. Ob und wie lange dies nun über die menschliche Lebenszeit hinausgeht, werden wahrscheinlich nur unsere Nachfahren berichten können, sofern es dann in über 500 Jahren noch die entsprechenden Laufwerke dafür gibt. Aber nach meinen Erfahrungen durch die meist hochwertigen Verbatim-Produkte bin ich mir absolut sicher, das hier zumindest kein Umkopieren mehr innerhalb eines gewöhnlichen Menschenlebens notwendig ist. Sofern alle o.g. Regeln eingehalten wurden, insbesondere was die Brenngeschwindigkeit und den Brenner (Pioneer oder LG) angeht, sollte es auch keine bösen Überraschungen bei der Abspielbarkeit geben. Bisher wurden alle M-Discs von meinen Panasonic- LG-, oder PS4/PS5-Laufwerken erkannt. Bei der M-Disc DVD gilt es allerdings unbedingt darauf zu achten, das das jeweilige Abspielgerät auch in der Lage ist mit DVD+R's umzugehen und möglichst halbwegs aktuell sind. Empfohlen sind hier ebenfalls Abspielgeräte bzw. Laufwerke von LG, Panasonic oder Sony, da sie Mitentwickler der optischen Medien sind und nicht ganz so empfindlich reagieren wie so mancher Billigplayer aus dem Supermarkt (Tevion, Medion etc.). Wer all diese Regeln beachtet und nicht an jeder Ecke spart, sollte noch sehr lange was von seinen Filmen oder sonstigen Daten haben. Noch etwas zum Thema "Fakes" bzw. der Behauptung, das es die M-Disc angeblich nicht mehr geben soll, was ich an anderer Stelle hier lesen mußte. Wer so etwas behauptet, hat entweder noch nie dieses Produkt gekauft oder möchte den Hersteller einfach nur schlecht reden. Die hier verkaufte M-Disc BD-R oder DVD-R ist sehr wohl das Original und verfügt auch über eine entsprechende Disc ID mit der Bezeichnung "MILLEN-MR1-000" (BD-R) oder "MILLENIA-001-01" (DVD-R). Einen entsprechenden Screenshot habe ich entsprechend beigefügt. Es mag sein, das es hier und da schwarze Schafe unter den Verkäufern gibt. Hier gilt es besonders auf die jeweilige Verkäuferbewertung zu achten und den Produktcode zu vergleichen. In jedem Fall muß die Disc ID im jeweiligen Brennprogramm mit den o.g. Angaben übereinstimmen. Falls dies nicht der Fall ist, sollte der entsprechende Verkäufer gemeldet werden. Zumindest die von Amazon, oder dessen Versand durch Amazon erfolgt sind auf jeden Fall keine Fakes und die Webseite des Herstellers besteht nach wie vor. Man braucht nur danach zu googeln.

Verbatim. Da sempre, il nome è già una garanzia. Perfetti (finora). Masterizzati con "Archgon Style masterizzatore Blu-ray esterno (lettore) USB 3.0 alu nero". Nessuna imprecisione. Solo il tempo potrà confermare la durata dei dati masterizzati... Ma mi sento fiducioso: ho ancora vecchi CD verbatim che funzionano ancora dopo quasi 12 anni...

affido a questi M-Disc il mio archivio fotografico digitale ( in doppia copia backup ) da sempre. Acquistati più e più volte, in tranche da 25, 50 e anche 100 GB, mai un solo disco difettoso alla masterizzazione. E per la durata della leggibilità vi diranno i miei posteri ... :)

Works well and fast on Panasonic DVD player
