BenQ Blank DVD Spindle, 4000 MB

A blank DVD holds around 4.7 GB — roughly seven times a CD, enough for a video, a large photo archive, or a full software backup. Like the CD it has outlived the drive in most laptops but stayed useful for the same reasons: a write-once copy nobody can alter, and a physical handover that does not depend on the recipient having an account or a cable.

This spindle carries the discs bare on a central post — the way to buy them for burning in quantity. Handle each by the edge, keep the data side clean, label on the printed face with a soft marker rather than a ballpoint, which can score through, and store the stack out of sunlight so the dye layer lasts.

• 4.7 GB write-once DVD-R
• Spindle of bare discs — bulk format, no cases
• For video, photo archives and full backups
• Label with a soft marker, not a ballpoint
