 \u00ab Le nouveau SSD SATA 4 bits de Samsung entra\u00eenera le passage massif aux disques SSD grand public de plus d\u2019un t\u00e9raoctet \u00bb, a d\u00e9clar\u00e9 Jaesoo Han, vice-pr\u00e9sident directeur Ventes et marketing m\u00e9moire chez Samsung Electronics. \u00ab \u00c0 mesure que nous \u00e9tendons notre gamme aux segments grand public et d’entreprises, les SSD de plus d\u2019un t\u00e9raoctet \u00e0 4 bits se r\u00e9pandent rapidement sur l\u2019ensemble du march\u00e9 \u00bb. 
\nAvec sa nouvelle puce V-NAND 4 bits d\u2019un 1 Tb, Samsung sera en mesure de produire efficacement une carte m\u00e9moire de 128 Go pour smartphones, ce qui entra\u00eenera une augmentation des capacit\u00e9s de stockage haute performance. G\u00e9n\u00e9ralement, lorsque les donn\u00e9es stock\u00e9es dans une cellule m\u00e9moire passent de trois \u00e0 quatre bits, la capacit\u00e9 de la puce par unit\u00e9 de surface augmente, mais la charge \u00e9lectrique (utilis\u00e9e pour d\u00e9terminer les informations d\u2019un capteur) diminue de 50 %, ce qui augmente consid\u00e9rablement la difficult\u00e9 de maintenir les performances et la vitesse au niveau souhait\u00e9 pour un lecteur. Cependant, le SSD SATA QLC 4 bits de 4 To de Samsung maintient ses performances au m\u00eame niveau qu’un SSD 3 bits, gr\u00e2ce \u00e0 un contr\u00f4leur SSD 3 bits et \u00e0 la technologie TurboWrite, tout en augmentant la capacit\u00e9 du lecteur en utilisant 32 puces V-NAND de 1 Tb de quatri\u00e8me g\u00e9n\u00e9ration \u00e0 64 couches. 
\nLe SSD QLC 4 bits offre une vitesse de lecture s\u00e9quentielle de 540 Mo\/s et une vitesse d’\u00e9criture s\u00e9quentielle de 520 Mo\/s. Il est en outre garanti trois ans. Samsung pr\u00e9voit de commercialiser plusieurs SSD grand public 4 bits dans le courant de l’ann\u00e9e avec des capacit\u00e9s de 1 To, 2 To et 4 To au format 2,5 pouces largement utilis\u00e9.<\/p>\n
