633-814

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.

As long as they're Optodisc these burn great, although sometimes only at 2x and not 4x or higher

The spindle of discs arrived quickly. Used with LG WP40NB30 (firmware CW01), burned at 4X or 6X. Will be using the discs primarily for backup. This was my first spindle of BD-R and I wanted to test out the water without overspending on BD-R media. The first two discs turned out to be coasters, but I suspect may be the fault of Acronis TrueImage 2014 (doing a partition backup in Windows). Subsequent discs seem to burn fine so far using CyberLink Power2Go. The media code identified by DVDInfoPro is OTCBDR002, which appears to be Optodisc. The BD CRC Read Error Test in DVDInfoPro returned 0 bad sectors and 0 suspect sectors; so this seems to be good news. At the end of the day, good price for the quantity. May consider purchasing more if the rest of the spindle burns fine.

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

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!

Work well with no glitches.

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.
