LG Electronics WH16NS40 blu-ray burner 16X BD-R SATA

Internal Blu-ray Burner for 5.25-Inch Bays

This internal optical drive fits a standard 5.25-inch bay and connects through a SATA interface. It writes BD-R discs at 16X and BD-R DL at 12X, while reading BD-ROM at 12X. DVD and CD media are also supported across multiple formats. The unit ships as a bare drive without bundled playback software.

SATA 150 Interface and Media Limits

The SATA 150 connection caps sustained transfer rates at 150 MB/s, which is below the theoretical peak of faster optical media. BD-RE and BD-RE DL writing are limited to 2X, and DVD-RAM writing reaches 5X. Random access on BD-ROM averages 180 ms. These constraints make the drive suited for archival writes rather than high-throughput duplication.

16X BD-R Write Speed Decides Suitability

The 16X BD-R write speed is the single figure that determines whether this burner matches a workflow. Users who need faster BD-RE rewriting or higher DVD-RAM performance will find the 2X and 5X ceilings restrictive. The 4 MB buffer helps sustain streams at the rated speeds. Buyers requiring quicker rewrite cycles should consider drives with higher BD-RE ratings.
