I just discovered that the Cat 5E cable I bought off eBay is not actually Cat 5E. It's labeled Cat 5E, but I can only get 90 mbps through it. Damn. I hate getting ripped off. Swapping out the cable with a known Cat 5E one immediately increased my transfer speed to over 300 mbps. I was copying a blank disk image to a Time Capsule. I'm deducing, then, that the drive in the Time Capsule (5th gen) is a USB 2.0 connection (the inside drive), with 480 mbps providing actual throughput of 300+. Which is all frustrating. I have a newfound desire for speed. I want my gigabit network to operate at gigabit. I should be getting transfers close to 1000 mbps, given the little overhead of wired ethernet. And which brings me to Thunderbolt. I hate that it's more expensive than USB 3, but I do want speed. So, no question in this post, but I thought I'd alert people to the fake ethernet cables out there. Searching through the web just now, it seems this is pretty common.
