Le Blue SN550 est au minimum en lecture et en écriture de très petits blocs de 4 Ko ou moins. Si vous déplacez des gigas de ce type de petits fichiers, alors le SN550 n’est pas le meilleur choix. Heureusement, la plupart des utilisations, comme le jeu ou l’édition, impliquent de plus gros fichiers, le SSD WD étant alors à son meilleur niveau.
La série SN550 va commencer à être disponible en janvier 2020. Notez que la version de base 250 Go à 70 $ aura moins de la moitié de la vitesse d’écriture que la version haut de gamme de 1 To.
