"I like the speed of this technology."

Translation: Ich mag die Geschwindigkeit von dieser Technologie.

[MurrayDouglas]

Why is "von" necessary here? Doesn't it work to say, "Ich mag die Geschwindigkeit dieser Technologie."? I though that this is how the possessive construct works in German.

'Von' is superfluous. Your answer is correct.

[thutson]

Once again, it's not accepting the "hat gern" construction for "like".

I don't think it sounds very appropriate in this context.

[Max.Em]

It would be "Ich habe die Geschwindigkeit dieser Technologie gern", but it's indeed very inappropriate. Gern haben has a strong "emotional flavor" that doesn't go well with an abstract term like the speed of a technology. It's used in situations like "I like you", "I like my teddy bear" or similar .
