Hallo zusammen!
Ich weiß nicht seit wann, aber schon seit längerer Zeit bemerke ich die schlechte Performance der Samsung SSD T5.
Gestern habe ich denselben Ordner am selben USB_3.0-Anschluss einmal auf die externe SSD kopiert.
Und das andere Mal auf eine externe HDD.
Dabei war aber ein extremer Übertragungsgeschwindigkeitsunterschied des ca. 23 GiB großen Ordners zu sehen.
Auf die SSD T5 lag die Geschwindigkeit meistens bei ca. 16 MiB/s, kurzfristig waren es mal ca. 70 MiB/s.
Hingegen auf die externe HDD, außer bei der Übertragung der 4KB-Dateien (?), lag die Übertragungsgeschwindigkeit zwischen 170 MiB/s und bis zu weit über 300 MiB/s.
Welchen Grund könnte das haben? Ich habe das USB-Kabel in Verdacht, eventuell auch die USB-Stecker.
Auch, wenn ich an den USB-Steckern oder am USB-Anschluss der T5 ohne Lupe nichts erkennen kann.
Außer die miserable Geschwindigkeit der SSD T5 betreffend, ist die SSD an und für sich scheinbar in Ordnung. Es funktioniert so weit alles tadellos.
So, dass ich mir über den Kauf einer neuen externen SSD aktuell keinen Kopf mache.
Aber gibt es für die Samsung SSD T5 das USB-Kabel auch einzeln zu kaufen? Besonders für den scheinbar speziellen Mini_USB-Anschluss der T5?
Ich habe zwar ein paar USB-Kabel mit einem Mini_USB-Stecker, aber der Mini_USB-Anschluss der Samsung SSD T5 ist einiges breiter.
Am Ende die aktuellen Smart-Werte der Samsung SSD T5.
Vielen Dank!
Gruß Andi
