OQBDR06LT-25 6X 25 GB BD-R Single Layer Blu-Ray Recordable Blank Media Logo Top

As a new owner of a Blu-ray burner to be used exclusively for archiving data, I've been looking into the best types of media.Many sources states the Verbatim disks available here are a sure bet:Verbatim BD-R 25GB 6X with Branded Surface - 25pk Spindle 97457 I purchased those first, tried them out, and I do like them.But with a recent significant price cut on the 50-pack spindle of the Optical Quantum, I had to give them a try. Sorting through the many reviews though is tricky. Here are all the facts of my setup (I think all these facts matter when you're trying to figure out if it's a hardware, media, or user error issue):My media was purchased on 5/27/17 and arrived 5/29/17. The burnable side is a grey/gold color. The media ID on these is OTCBDR-002-000. That's the same as the Plexdisc available here:PlexDisc 633-214 25 GB 6x Blu-ray White Inkjet Printable Single Layer Recordable Disc BD-R, 50-Disc Spindlethough those have an InkJet printable front surface. The non-burnable surface of these is a goldish grey with a somewhat matte finish.Looking at the Blu-ray Disc Association License office website, these are made by Amethystum Storage Technology Co., Ltd. Looks like a Chinese company? The disks are HTL.My burner is a LG WH16NS40, which I purchased earlier this month. It is on the latest 1.02 firmware, as my burner is the NS50 revision (though the model # does not reflect that).My burning software is the excellent freeware program Imgburn v2.5.8.0.If you search the Myce forums for the media ID, you find some folks reporting they don't burn very well at the rated 6x. However, since receiving the Optical Quantum disks, I have burnt and verified 9 disks without issue. I intend to go back and do a random check of the data soon to ensure the burn lasts.I have used only the 6x speed, as that's what they're rated for. It takes ~16+minutes to burn 25gbs. I then use ImgBurn's verify after each burn, which takes another 14 minutes.So far, I have not had any errors. The 'verify' technique on ImgBurn compares the written data to the source data, so I do trust it. (To be completely transparent, the author of the software has stated that if it passes this verify, it means that the data matches, in that drive, and is readable, at that time--for sure, media can degrade).With Amazon's excellent return policy, I had no qualms about giving these a try, and so far I'm quite satisfied.

I've used literally over 5000 of these BD-25s and BD50s for backup purposes at work. What I've learned will hopefully save someone out there a lot of headache and/or heartache over data loss.These discs, and all discs (except M-Discs), are NOT meant for long term storage. They use a partially organic dye that WILL begin to erode over time, corrupting the disc and losing all of the data stored on it. You can write the disc, place the disc in a case, put in on a bookshelf and never use it again and it will still fail eventually. Others have posted photos of what this looks like in their reviews so I'm not going to. The point to learn here is DON'T store ANYTHING that you don't want to lose on a disc (except M-Disc).These come with two different types of dye. There's one that's a blue/purple color and another that's gold in color. What you want is the gold. Those last A LOT longer than the blue/purple dye. The problem is you never know what type you're going to get. I've had the blue/purple dyed discs begin to erode in just a couple of months of no use. I have yet to have a gold dyed one fail and many are over 10 years old but I know it will still happen eventually. The BD-50s are more likely to have gold dye than the BD-25s.For what they're meant for, short term storage, they work great. Just don't use them for long term storage because you will lose everything you have saved. It's just a matter of time.

I buy these and never have any coasters like I do with some other big name brands.

This would probably be my 5th purchase of these Optical Quantum BD-R's.I've only purchased the 'logo top' version, as I prefer to write my own label on the disc rather that print the label.They are very good good for the money I paid, and have been very reliable....even for discs that I've burned over 2 years ago.I use Pioneer brand Blu-ray burners (BDR-209D & 212D) and have very rarely if any, gotten a bad burn or failure.For the price and quality, I'd buy them again.

I bought these because they had a high rating and were a #1 seller, but I'm returning them and buying Verbatim discs instead (per a recommendation elsewhere).I only just started burning with these tonight, with my LG burner and ImgBurn... but I stopped and contacted Amazon after ONLY ONE (1) OF THE FIRST SIX (6) discs was successfully burned. Having at first set ImgBurn to AWS with poor results, I then tried setting the write speed to 4x for the 6th disc. But it also failed.I've had experiences like this before with DVD+R discs until I found a good brand. And I know what I'm doing, so it's not me--the media is just very poor quality. Don't buy these. You run the risk of having many coasters. Fortunately, Amazon has wonderful customer service and offered me a refund.Following is an excerpt Imgburn's Log file:I 21:20:00 Writing LeadIn...I 21:20:00 Writing Session 1 of 1...

Cheap blank discs tend to make more coasters than serve as reliable storage devices for important files. I tend to import and buy the more expensive discs from Japan because I don't have time to find out I have had a bad burn.These discs are a good value cost-wise and I have had no coasters on my first 5 burns.There are 20 more blanks to try on this spindle. I hope to re-order this brand if I make it through the spindle with no coasters.I don't know about longevity. I have never had a disc of any brand that failed after a good burn. I have discs I burned 20 years ago that won't read on my newer reader, but the discs still work on my oldest readers. If I remember, I will update this review in 20 years. (haha)For print quality, the top surface is a bit shinier than the expensive brand disc, thus making it slightly harder to label with a sharpie pen. But the marks are readable and tend not to rub off.

Good value

Great discs, out of the whole spindle I only had one error and I’m sure it was my fault during the burning process.

Rapporto qualità prezzo ottimo. Dopo averne utilizzato qualcuno, al momento nessun problema riscontrato.

Arrived in good condition and was very useful!

J'ai eu très peur quand la gravure du tout premier blu-ray a foirée. Mais les 49 autres sont passés comme un charme! Donc je conseil!

I usually use these for large data archival jobs and they almost never let me down. Very rare for me to burn a coaster with these using my BDR-209D. Will buy these as long as they sell them and I recommend them to anyone looking for long term storage.

Good value for money, works great,
