Il Blue SN550 mostra la sua debolezza nella lettura e nella scrittura di blocchi di dimensioni molto piccole di 4 KB o inferiori. Se il vostro lavoro comporta lo spostamento di gigabyte di questi piccoli file, allora l'SN550 potrebbe non essere la scelta migliore. Fortunatamente, la maggior parte delle applicazioni come il gioco o l'editing coinvolgono file molto più grandi dove l'SSD WD è al suo meglio.
La serie SN550 inizierà ad essere distribuita a partire da gennaio 2020. Si noti che l'opzione base $70 250 GB avrà meno della metà delle velocità di scrittura dell'opzione 1 TB di fascia alta.
