Video Description

Sofern man keinen wirklich riesigen Speicherplatz braucht, sind SSDs auch für externe Speichermedien die erste Wahl: Festplatten sind überhaupt nur noch sinnvoll, wenn Kapazitäten oberhalb von 1-2 Terabyte möglichst günstig gefragt sind. Doch wie unterscheiden sich eigentlich verschiedene Flash-Speicherarten? Ist ein USB-Stick nur eine langsame und billige SSD, oder gibt es spezifische technische Unterschiede? Warum sind MicroSD-Karten bei gleicher Kapazität meist ähnlich teuer wie einfache NVMe-SSDs, obwohl sie doch viel langsamer sind? Ist die Ausfallneigung von SD-Karten nur ein längst überholtes Klischee? Über diese und weitere Fragen, aber auch über unseren aktuellen Vergleichstest externer SSDs sprechen wir in dieser Folge des c’t uplink.
