So I went to CA and got that readynas and some HDDs as well as ordering a 20m cat6 cable to go with it, I've gotten home to discover they've given me a Cat5 instead (though charging me for Cat5). I need to get this thing installed using some cable covers today and they close at 3. Is it worth taking it back or will I find no difference anyway? both my router and the readynas are gigabit.

use cat5

call ca get credit for diff in price

i thought cat6 was mainly for futureproofing anyway

yeah cat6 isn't going to make a difference when you're not going to be able to transfer data anywhere near the 1000 megabit connection limit
your readynas probably does 200~mbit per second, the cable is capable of 1000mbit
if you had a fully sick nas with more drives it might come close, but even then it would hardly be worth the drive back

It will be cat5-E anyway, and that doest realy have any issues doing gigabit connections, expecially over 20mtrs.

CAT6 just means you dont have to worry about interference from electrical etc over longer runs.

There is about two fifths of fuck all difference

I highly approve of this euphemism, though I like to say five eights of fuck all.

He didn't pay for cat6.
