Connaissez-vous BitLocker ? On est pr\u00eat \u00e0 parier que pour la plupart d'entre vous, la r\u00e9ponse est non. Pourtant, cette application native de Windows tient un r\u00f4le essentiel. Pr\u00e9sent sur les version Pro du syst\u00e8me d'exploitation, cet outil est la solution de chiffrement propri\u00e9taire de Microsoft, qui vise donc \u00e0 s\u00e9curiser les donn\u00e9es stock\u00e9es sur un disque ou un SSD.<\/p>\n

Concr\u00e8tement, l'application cr\u00e9e les partitions n\u00e9cessaires sur le p\u00e9riph\u00e9rique de stockage avant de les prot\u00e9ger par une cl\u00e9 e chiffrement. Activ\u00e9e par d\u00e9faut, elle tourne ainsi constamment en arri\u00e8re-plan, ce qui a n\u00e9cessairement un impact sur les performances de votre PC. Et pas des moindres : selon nos confr\u00e8res de Tom's Hardware, Bitlocker peut faire chuter de 45% les performances des SSD sur Windows 11<\/a>.<\/p>\n
