I have a white mybookworld 2T and a mybooklive 2T (since yesterday).
I'm a SL mac user, MBP.
I've noticed since the beginning that white one was quite slow. I was used to it, even if I try few times to speet it up. It wasn't a big deal.
But since yesterday and the arrival of my mybooklive, i'm surprised how fast this one is compared to my first one. Access to file is much faster.
I really don't understand why.
Both use AFP connection, via same routeur.
