The Sony BNE25RH is a BD (Blu-ray Disc) by Sony. The BNE25AHE is a rewritable BD which means that data once written on to the disc can be removed and new data can be added. Rewriting can be done while preserving the reliability of the BNE25AHE disc through the introduction of a new recording layer that is extremely durable. Like the BNR25AHE (Write-once), the BNE25AHE too features Scratch Guard that ensures that your BD can be used easily without fear of data corruption by preventing scratches and stains. Data can be transferred to and from the BNE25AHE BD at a rate of 72 MB/s.
