The LaCie d2 Blu-ray XL allows you to create, save, and share your digital files on most current and legacy optical discs. Recording performance is based upon the disc type, format, and speed rating as well as its physical condition (i.e. scratches on the surface, dust, etc.).

BD-R (Single or dual layer) / BD-R XL (Triple or quadruple layer)
Blu-ray Disc Recordable. Record data once and it will never be erased. This is the ideal format for archiving valuable data or storing and distributing video material.

BD-RE (Single or dual layer) / BD-RE XL (Triple or quadruple layer)
Blu-ray Disc Rewritable. Record over data or video that you do not wish to keep. Good quality Blu-ray discs can be overwritten approximately 10,000 times. Additionally, you have extensive editing functionality to this type of disc. This is the ideal format for making sequential backups and recording video for time shifting purposes.

BD-ROM
Blu-ray Disc Read Only Memory. A BD-ROM disc contains pre-recorded data. Although a BD-ROM may store any form of data, most feature HD movies for playback on Blu-ray Disc players. A BD-ROM can be played back on your computer using the LaCie d2 Blu-ray XL provided that you have:

• The required playback software
• A compatible computer
• A compatible graphics card
• A compatible monitor
