Comment convertir des To en Go ?

Multipliez le nombre de téraoctets par 1000. C'est la définition décimale, celle des fabricants de disques et de la norme internationale. Windows divise par 1024 et nomme le résultat Go alors qu'il s'agit de Gio, d'où l'écart de 7 %.

Go = To × 1000To = Go ÷ 1000

Où ces deux unités servent

Sur une même machine, la mémoire vive se compte en puissances de 1024 et le disque en puissances de 1000 : deux gigaoctets différents cohabitent dans le même boîtier.

Questions fréquentes

Pourquoi mon disque de 1 To affiche-t-il 931 Go ?

Le fabricant compte 1 To comme 10¹² octets. Windows divise ce nombre par 2⁴⁰ et étiquette le résultat To, alors que ce sont des tébioctets. On obtient 0,909 To affiché, soit 931 Go. La capacité n'a pas bougé, seule la définition change.

Combien de films tiennent dans 1 To ?

Environ 250 films en 1080p à 4 Go pièce, ou une cinquantaine en 4K à 20 Go. Pour des photos de smartphone à 5 Mo, comptez 200 000 clichés.

Faut-il prendre 1 To ou 2 To ?

Pour un usage bureautique et photo, 1 To suffit largement. Le montage vidéo, les jeux récents à 100 Go et les sauvegardes locales justifient 2 To ou plus. Le prix au téraoctet baisse avec la capacité, l'écart est rarement du simple au double.

Un SSD de 1 To contient-il plus de 1 000 Go de mémoire ?

Presque toujours. La puce porte 1 024 Gio de flash, soit 1 099 Go décimaux, et n'en expose que 1 000. Les 9 % retenus servent au surprovisionnement : remplacer les blocs usés, répartir les écritures, absorber le ramasse-miettes. Sur les modèles professionnels la réserve atteint le quart de la puce, ce qui explique les capacités vendues 800 Go plutôt que 960.

Pourquoi le montage vidéo se compte-t-il en téraoctets ?

Parce que les codecs de tournage n'écrasent presque rien. Le ProRes 422 HQ en 4K à 25 images par seconde tourne autour de 590 Mb/s, soit près de 265 Go par heure : moins de quatre heures de rushes remplissent un téraoctet. Le même film livré en H.265 à 15 Mb/s tient dans 7 Go l'heure, quarante fois moins. Le stockage suit le format d'origine, pas la durée.

Combien de Go dans un To ?

1000 Go, en comptant par milliers comme le fait le fabricant. Windows compte par 1024 et écrit quand même Go, si bien que le même disque affiche 931 Go. Rien ne manque : les deux chiffres comptent les mêmes octets.
