Lyhyen käytön jälkeen olen erittäin tyytyväinen ostokseen. Seagate on hintaansa nähden nopea ja luotettava – minulla on ennestään yksi samanlainen 2 TB muisti, joka on vuosia vanha ja toimii edelleenkin moitteetta.

Selve harddisken er perfekt, men desværre medfølger der ikke kabel, så der kan øverføres filer. Det må man desværre selv finde ud af. Ellers tilfreds.
