At first try, these PlexDisc 6X blu-Ray discs are not usable. BUT, PLEASE BE SURE TO READ MY UPDATES. Writing defaults to 1X and gradually slows to less than 2 MB/s. After an hour or so, it bombs completely. Out of the 50 discs, I have 31 left unused and NO usable recordings. I had been unable to complete any disc. Other brands write properly. I used an ASUS Blu-Ray burner in a Win 7 PC Also a ProDuplicator with 3 LG Blu-Ray Burners (All new ones rated for Blu-Ray M-Discs) Physically, the discs look great but simply DID NOT WORK. They were low cost but also seemed to be low quality. UPDATE April 27, 2016: I have to alter my opinion. After such dismal failure writing with Win 7 and the ProDuplicator, I tried ImgBurn and found the discs to write 100%. Both the Win7 and ProDuplicator had up-to-date drives that burn CD, DVD, and Blu Ray RE's well. It's surprising but ImgBurn works where other software doesn't. Incidentally, the PlexDiscs ID is OTC BDR-002-000, The surface is a golden color, the white printable surface makes for nice labels and the thickness (noted by some as thin) seems to be standard - like all the others. After the successful burning with ImgBurn, I may even buy these again. UPDATE May 22, 2016 After changing to a Blu Ray Duplicator by CopyStar, I found these discs to write in the CopyStar 100 per cent. I have revised my rating to 5 stars. Good discs and good price.,

I just bought the PlexDisc 25GB 6X BD-R White Inkjet Hub Printable 25 Pack Spindle and the PlexDisc 700MB 52x CD-R White Inkjet Hub Printable at the same time, so far they have outdone my previous (and numerous) Verbatim in every way. The picture that says "Bonus Disk" under "The Wall" was a SCAN of the one without the "Bonus Disk". I simply added the text since I no longer have the original copy...as you can hopefully tell from the images, the print came out BETTER than the picture it was copied from. Same printer, same set of ink. Canon Pixma TS9120 if anyone is curious. Burned on a Pioneer XS07UHD USB 3.0 External Burner with no issue doing a Clone of the bonus disc copy I had with no label on it, just sharpie. It works perfectly fine, and looks better than my Main Movie lol. I'm tempted to copy the main movie again after buying some PlexDisc BD-R DL to make them look identical heh. I did a text only CD-R and a Picture with text BD-R both from the bottom area of the stack and both without so much as a hiccup, I can't speak for the lifespan or if I'll end up with any duds yet, and I will update both reviews if I get alot. But so far, like the CD-R rack, best bang for your buck right now, pretty much anywhere. These things are great, hopefully they never drop the quality or raise the price because I found a new disc dealer.

So far so good. Writes well, reads well, very few if any blemishes.

I'm leaving space up front for updates later as I just bought these and haven't burned much yet. These are the blue-coated discs. Another reviewer mentioned older ones having a gold dye instead of blue - likely from a different manufacturer under the hood. They stated that they were having problems with getting coasters pretty often with the blue coated discs. I took a peek at the details from ImgBurn (see first image) and found that the blue-coated discs that I got are CMC Magnetics discs (CMCMAG-BA5-000). What stood out to me was that they claim to support 8x, 10x, and 12x write speeds, which are multiples up to double what the packaging claims they are. This seems to highlight a potential reason for excessive coasters. So far, I've only burned one disc and I purposely limited it to 6x in ImgBurn and it was successful. For what it's worth, I'm also using a Pioneer burner at this time. I have an LG burner, but had some issues with it elsewhere, so I'll probably stick with the Pioneer on these as I know it can reliably produce burns. I have plans for using these, so I will update down the road on how that goes, but for now they seem okay. I've checked the surface on a bunch of them and they all look clean and without any visual defects. Update 7-16-25 I have burned 10 discs from the set as of today and have had NO failed burns so far. I have been keeping the source images around so I can continue to test them for premature degradation and have had all test good. These have all been burned with a 6x rate limit as described before. Discs are continuing to look good! Of course, testing them too frequently can cause them to degrade from the usage, but there is no evidence of issues from the burn quality. Update 8-31-25 Ive burned 14 of the discs from the set and have continued to have no issues at 6x burn rate. I started to figure I will need another set later on, so I bought another one and ended up with the orange/copper coated discs others were talking about! There may be one other variant by Ritek but I have yet to see them. The MID on these is OTCBDR-002-000 (see second image) which I have seen used quite a bit by other brands on Amazon. These are manufactured by OptoDisc (not to be confused with Amethystum who sounds like they use the same OTCBDR-XXX-XXX MID). The optical quantum discs are another OEM using OptoDisc... and unfortunately the reviews of that disc variant are not great (and yes it is that specific manufacturing variant). They look to be having a lot of issues with disc rot where the dye breaks down and disrupts the reflectivity of the surface - making data indiscernible by the disc drive. This isn't *supposed* to happen with HTL type disc dye, but it is and optical media does in fact degrade eventually - especially with a bad storage environment. I haven't burned any of these yet as I just got them today. I'm debating whether I want to test them out for the sake of knowing at the expense of 30 bucks... From what I have found CMC Magnetics is a brand more familiar and frankly reputable. They manufacture Verbatim's media and have been behind other magnetic media we've seen in the past (TDK, Maxell, etc. for video tapes) Optodisc seems to be a grayer area. The good news is you can tell which type of discs you're getting a hold of without opening the wrapping. The CMC Magnetics cake box has thin plastic contour around the indentation (image 3) or you can check out the Verbatim 25G 50 pack cake box, it is the same package I have. The OptoDisc cake box has broader rounded contour around it (image 4) - a subtle difference but noticeable - or you can check the Optical Quantum listing or the PlexDisc imagery on this listing. I also noticed there is an engraving on the OptoDisc ones showing their branding (image 5). It is mirrored in person but still readable with the right angle of light reflection I flipped the image for readability. Another way is to check the part number on the side. The CMC Magnetics discs are manufactured by OptoDisc Taiwan allegedly (image 6), which is consistent with CMC Magnetics being based in Taiwan, with part number 633-214C. The OptoDisc discs are consistent and say manufactured by OptoDisc (not OptoDisc Taiwan! Image 7) and the part number is 633-214 as shown in the product listing. The sales SKUs are the same, meaning they are sold as interchangeable items. It seems the CMC Magnetics variant is left up to chance that you get a hold of it, as they are usually more expensive if bought from Verbatim.

Update 8/7/20- For years I have sung the praises of PleXdisk BD-R's. Hopefully this last group was a fluke (QC asleep at the wheel for 1 batch). In this group there have been 12 with visual flaws (i.e. lateral streaking) and as it turns out these disks are either un-writable (10) or will write at a very low speed (2). The severity of the visual blemishes coincides with the problem. I will order another 50 pack in the future but if I find the same problem , I will have to assume a down trend in quality of PleXdisk BD-R's. I still recommend PleXdisk as hopefully this is a one time problem. My advice is when you receive your 50 pack do a visual check of the recording surface. Streaking = Coaster. Previous review: I've been using these disks for about 4 years, with very few "coasters". The majority of failures are due to my own errors using Burn Aware (not their fault). I have noticed that when I use my LG burner there tend to be more failures, than with my Pioneer BD209. As a side note the Pioneer also reads and writes faster as well. As far as longevity... disks burned 4 years ago still work fine. It does seem that these disks are getting a little more expensive (by a couple of $), but still seem to be a very good value.

Excellent Blue ray pack. The quality of the product is great. I haven't had any problems burning some huge files on these.

With recordable media you have 3 main factors that determine how good it will be: 1) Manufacturer 2) Recording layer type/Dye type 3) Quality control #1 These discs are manufactured by Amethystum Optoelectronics, currently the highest quality BD-R manufacturer. So top marks there. #2 These discs do NOT use a dye. They use copper plated silicon, otherwise known as HTL. This is more expensive but is longer lasting than using a dye. (The LTH disc type uses a dye and so is the cheap, but is inferior - these discs are not LTH.) Top marks again. #3 Quality control - discs coming off a production line have varying quality. Through testing, the best discs can be sent to resellers like Verbatim who charge a premium for high quality product (at least in theory). What grade are these Plextor badged discs? No one can be certain, but usually low grade discs will get bad product comments, and there are very few bad reports about these discs, so they're at least a decent grade. Since they come from such a top manufacturing pedigree, they're likely to be just fine for most.

I really wanted to give this 5 stars because before they ALL worked. I ordered 5 of these from this seller before here on Amazon and never had a coaster/bad burn with them until this month. The last spindle I ordered had alot of coasters, I would say when I got to the 28th bad disc I decided to order another one and low and behold, the same thing. So this time when I got around to the 34th or 35th bad disc, I went on eBay and found the same discs from the same seller so I said let me order another one just to see if it was just 2 bad batches I got before. Out of a pack of 50, only 8 worked and yes you read that right ONLY 8 of them worked and the other 42 were coasters. I thought it was my drive and checked it out and it was fine burning DVD's and data and also tried other BD-R's and those worked fine with no problem and I also tried burning at 2x, 4x (which is the one I always use) and even 6x and the same write error in the beginning. It's a bummer because I needed to get a whole bunch of Blu-rays done before the New Year and this literally messed up my plans so I will stay away from these for a while until Plex Disc ships out some new ones and I won't bother buying until March or April and then to top it off the seller raised the price to these discs by $5 which is NOT worth it if I am getting all these coasters/bad burns. I hope they get their stuff together if they want to continue to have customers. UPDATE EDIT: Jan 2022. Now the Dual Layers went up to 20.99 from 17.99 and the single layers went up to $29.99 from $21.95. SMH!

I bough these while in a pinch, after doing some careful research, because I could not find equivalent Verbatim discs at a reasonable price. Every disc burned so far can be read flawlessly by multiple players and computer drives. It remains to be seen whether they will degrade over time or not (like other cheap brands), but for the moment I'm cautiously optimistic.

Arrived quick, drive couldnt recognize disc.. but after a few ejects it found it and burned just fine. Great price and has nice white printable coating.

Had a few of these now. And overall very happy. The face is printable or you can scribble on with a Sharpie. No issues burning at 4x with Imgburn.

Premier blu-ray illisible. Second blu-ray illisible. C'était mal parti. J'ai décidé d'en tester 20 sur 50, et d'émettre une réclamation si nécessaire. Finalement, après plusieurs essais pour certains , j'ai réussi à en formater 19 (sur 20), j'en ai gravé 1 pour test avec succès, donc c'est acceptable. A ce moment, je n'ai eu qu'un échec sur 20. Mais ce n'est pas la qualité prévue, et je n'en recommanderai pas. C'est la première fois en trois ans que j'ai un rejet sur mon graveur. A quelques euros près, d'autres marques sont plus performantes. (Commentaire 2018). Commentaire complémentaire en 2024 : La quinzaine de blu-ray enregistrés il y a 5 ans sont pratiquement illisibles, la plupart nécessitant une dizaine de lancements pour accepter d'être lus (essai sur plusieurs lecteurs). J'ai donc recopié ceux que j'ai pu sauver, et j'ai prévu de broyer la totalité du lot. Je n'ai eu ce désagrément avec aucune autre marque. Ce n'est pas une bonne expérience.

rápido, barato y bueno.
