Blu-ray Features:
The Panasonic SW-5582 supports writing and reading the Blu-ray Discs (BD-R/BD-RE SL/DL) at a maximum 2x speed.
A Blu-ray Disc (BD) is a next generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of many leading consumer electronics, personal computer and media manufacturers. The format was developed to enable recording, rewriting and playback of High Definition (HD) video, as well as high capacity of data storage.

Before using BD-R and BD-RE media for writing files on the disc, we must logically format the media. Once we have logically formatted BD-R or BD-RE disc, it can be use to write files just as you would do with a floppy disk, hard disk or DVD-RAM. In the illustration below we will use Panasonic UDF Formatter (DVDForm) version 5.1.1.0 to format a BD-RE disc.

DVDForm offers several format types for BD-RE disc
It took 37 seconds to quick format a BD-RE disc in FAT32
BD-RE Single Layer discs formatted with FAT32
Now we will attempt to do a quick format on a BD-RE media with format type UDF2.5.
Formatting a BD-RE disc in UDF2.5
BD-RE Single Layer discs formatted with UDF2.5
In the above illustration, using DVDForm 5.1.1.0 for BD-RE disc we can select format types of UDF 1.50, UDF 2.00, UDF 2.50, and FAT32. Whereas for BD-R/BD-R DL discs only format type UDF2.60 is selectable.
Only Format type UDF2.60 is selectable for BD-R disc
We can only select UDF2.60 for BD-R DL disc.
Note: Once a BD-R disc has been formatted, we can write, add and delete files on the disc. However, if we delete a file, the free space of a disc will not increase. Only a blank BD-R disc can be formatted, hence a formatted BD-R disc cannot be re-formatted.
Blu-ray Disc Writing Speed and Quality:
To demonstrate burning data on a Blu-ray disc, we use an ISO Image from a pre-authored data files with a total on-disc size of 23,000MB. We then wrote this image file using Nero Burning ROM 7 on a Verbatim BD-RE Single Layer 25GB media. The ScanDisc test is performed in the Panasonic SW-5582 drive to check if there is any issue with the burned disc. Below are the results:
The burn was completed in a lengthy 1h:39m:05s, however the result is good. Apparently Nero Burning ROM 7.2.3.2b is set to 'verify and write" when using this drive, and thus the actual speed was less than 2x.
BD-R Writing Speed and Quality
Now let us take a look how the drive performs on various BD-R media:
