Buying Guide

Choose capacity based on backup size

Pick 25GB BD-Rs for smaller archives and 50GB or dual-layer 50GB BD-Rs when you need fewer discs for large datasets to reduce disc management overhead

Match write speed to your burner

Use discs with write speeds supported by your Blu-ray burner (example: 8X or 16X) to avoid failed burns and to get predictable write times

Consider pack size and cost per GB

Larger multi-packs often lower the cost per gigabyte; compare pack counts (e.g., 10‑pack vs 25‑pack) and price-per-GB when planning long-term backups

Prefer reputable media brands

Established brands with consistent quality reduce the risk of errors and improve long-term readability for archived backups

Check dual-layer for denser storage

Dual-layer BD-Rs provide 50GB on a single disc, which simplifies backups for very large files but may burn slower or require compatible drives
