SSD externe : courte critique du Samsung T5

Silvio Werner, Klaus Hinum (traduit par JBP), 09/18/2017

Samsung a présenté son SSD T5, le dernier modèle d’une série de SSD hautes performances. Tout comme ses prédécesseurs, le T5 offre des taux de transfert de données vraiment élevés, et un package de haute qualité, mais il manque d’innovation.

Le T5 est un nouveau modèle légèrement plus rapide (en particulier dans MacOS), parmi la gamme de SSD externes de Samsung. Mais au quotidien, les gains de performances sont négligeables.

La qualité générale et les bonnes finitions sont convaincantes, ainsi que la compatibilité iOS / Android et le cryptage matériel. Étant donné que le T3, contrairement au T1, avait déjà un boîtier en métal, nous aurions souhaité une certification IP - par exemple des SSD comme le ADATA SE730 peuvent être immergés dans l’eau.

Tout compte fait, nous pouvons recommander le T5, mais les progrès par rapport au T3 sont négligeables. De ce fait, le choix final entre les deux produits se fera probablement en fonction du prix, pour l’instant inconnu, du T5.
