633-814 25 GB 6X Blu-ray Logo Top Single Layer Recordable Disc BD-R, 50-Disc Spindle

So far so good. 16 burns, no failures. Using Pioneer BD209, and BurnAware Free, at max speed (in this case 7x to 7.4x). I will definitely order these again... soon. Update: Make that 36 and no failures. Update 2: I'm now into the second order of these disks without a coaster. Add to that a consistent burn speed of 7.2X, and you have a winner. Not enough time has passed (a few months) to determine data retention, but will check back if I have a problem. Update 3: 3 packs down, still no failures. I'm impressed. Update 3: Second spindle done. 1 failure (my fault). Great product. Ready to reorder. Final Update: Wow, These are a fantastic value. Several spindles now without a problem. 7x burns, not a problem. Data retention after 1 year, 100%.

I have only used a few, but no defects so far. The media is HTL, so it may be inorganic, but no official info. The reflectivity is better than other HTL and the write contrast is much better than other blu-ray discs. It registers quickly when inserted, a good indicator of readability. My recorder will write these at 8x, and they are officially rated to work at 8 to 12x speeds depending on the recorder - great speed! I have now burned 100 discs. I had 2 defective discs, very reasonable for a cheaply priced product. They work just fine on the four players tested, included an old flaky player that has difficulty with many discs.

All of these burned flawlessly. Hope they have a good shelf-life.

These disc are great, I have been using Optical Quantum Blu-ray disc and decided to try these PlexDisc and they have reached my expectations to the fullest. My only problem with them is when I use my LG Blu-ray burner it sometimes don't recognize the disc but I also have the same problem when using the Optical, I think it's the burner and not the disc. So I use my ASUS Blu-ray burner instead and they are great!!!!

Work well with no glitches.

I have had very few coasters with these! Of course, there will ALWAYS be the occasional bad disc (even from Verbatim!), but these are the best bang for the buck you're going to find!

I have made many backup disks with these, not of my operating system, (MX LINUX) but of the many pictures, music and schematic drawings that I have down loaded. I then delete them from my SS HD since I read that full SS HDs fail way more frequently than half full drives. Properly labeled and printing the directories of the disks means that I can insert the correct disk and retrieve the proper file in a very few minutes. I have zero problems using these disks at a their value prices. I am a experienced CD-R (data and music) + DVD writer/user. Ron W4BIN

This is specific to the PlexDisc 633-814 BD-R disc media. Unfortunately, they've proven unreliable for my use with 22 of the first 25 of the 50 discs on the spindle discs having failed to burn without errors. I've disposed of the remaining 25 discs and am returning the remaining 3 spindles. As matters of information: 1. I use between 3 and 5 BD-R discs each day in the creation of archival backups of data. 2. I've been using Verbatim 98397 BD-R discs for several years. Each disc is accounted for. 3. Only 8 of more than 3,300 Verbatim discs have ever failed to burn without errors. All of those 6 failed due to failing burner devices which were then replaced. But the cost for those discs has risen to a point that I am looking for a less expensive replacement. 4. I use only the LG WH16NS40 Blu-ray burners, and the Nero Burning Rom software with a writing speed of 4x and with data verification enabled. I hope that others will find the review helpful.

Very good disc to burn and to write on themselves I am very satisfied

I use these for archiving data files for graphic arts. They burn very reliably, seldom any writing problems or wasted disks.

I have countercheck with the disk from another source which more expensive but give a 100% burn success rate, it seems that no point to save a 30% cost but end up 50% of the disk not usable with all the time wasted on keep trying.

Haven’t had one fail during burning process. Plays smoothly.

Excellent product, work great, n9 problems so far.
