Buying Guide

Choose capacity for your backup needs

Single-layer 25GB discs are convenient for smaller archives while dual-layer 50GB BD-RE DL discs reduce disc swaps for larger data sets

Check rewritable cycle rating and durability

Rewritable media like BD-RE is designed for multiple overwrite cycles; prioritize brands with consistent user ratings and documented longevity for regular backups

Match disc speed to your drive

Speed ratings (e.g., 2x, 4x) affect write times; pick discs that your Blu-ray burner supports to avoid slow writes or failed burns

Consider pack size versus per-disc value

Multi-packs (20–40 discs) lower per-gigabyte cost and reduce packaging waste for frequent backups compared with single-disc purchases

Look for printable or marked surfaces if needed

Printable top surfaces simplify labeling and organization; choose printable discs when you expect to catalog backups physically
