Explanation

Optical media such as Blu-ray discs (BD-R) offer the lowest cost per gigabyte for long-term archival storage, making them the most economical choice for backing up large amounts of static data like DVDs and photos that will rarely be accessed. They also require no power to store and have a long shelf life. A 5,400rpm HDD (A) is affordable but more expensive per GB than optical discs for pure archival use. M.2 NVMe SSDs (B) are fast but costly, making them inappropriate for economical backups. A SAS RAID array (C) is an enterprise solution with high cost, far exceeding what is needed here.
