2011 Airs 450mbps Wi-Fi?

I've got the latest generation Time Capsule already, and a 2011 13" Air on the way, so if nobody beats me to it, I'll def update this thread!

thanks i would appreciate it ...

typically how apple is silent about it's technical specs not only on the macs themselves but also on peripherals...

I bought the 2TB Time Capsule with my new MBA, and a 70GB restore took 4 hours.... :(

Could you copy a file that is at least 1 GB and tell us how many megabytes per second you're getting? Finder does not show this info, but you can download a trial of PathFinder and do the copy using it.

Edit: please do the test using Ethernet and using wireless, if you can. The TC is not known for it's capabilities as a "NAS", but at least we will get some idea.

Will do. I am about to go to the Apple store to pickup a USB Ethernet adapter, and will download Pathfinder to see whats up.

EDIT: I copied a 1.5TB movie and it started at 15MB/second and slowly dropped to 10MB/second as the copy progressed. Definitely a lot faster than Time Machine restoring from it. Odd. Ethernet cable is not here yet.

I'm about 6 feet away from my new Time Capsule right now on my 13" i7

Thank you both. The speeds are inline with what I would expect for real world N wifi.

Copy performance for one large file is better than lots of small files, which is what a large part of your TM backup would consist of. A TM restore would also require more CPU power than a simple copy.
 
I would imagine the bottleneck to be the hard drive in time capsule in vow's case.
One might try between two airs on an ad-hoc network to be sure or even better, copying between two ram-disks or similar.

Even a 5400 RPM can easily exceed the fastest wifi speeds. The bottleneck is in the TC itself and its lack of processing power.

Forgot to mention that I was copying to my NAS box that's hard wired to the Time Capsule.
 
I just copied the same file to my Time Capsule using an ethernet cable and the USB Ethernet adapter.

Same speed. 10.5MB/second.

Sigh.

Would that possibly be the fastest the Time Capsule can write a file?
 
Still not fast enough to support my home connection atleast. I get around 70-80 Mbit depending on where I am in the apartment, so around 10 MB/s. Too bad, I was hoping it would be quick enough not to be a huge bottleneck at home. I see no difference between this one and my 2010 MBP.
 
It's quite simple.

You need 3 antennas for 3x3 MIMO, as currently found in the iMac and MacBook Pro.

If you saw the pictures from iFixit you could clearly see that only 2 antennas are going to the Wi-Fi/Bluetooth board.
 
Thanks for the reply. I see now. I just had a look at the macbook pro teardown and you can clearly see 3 antennas. It appears that they are using a broadcom chip in the Airs still which in not compatible with 450mbs anyways.

That must be one hell of movie. Perhaps it is 1.5 GB?

There are only 2 wifi stacks in the Air according to anandtech, where each stack can handle full duplex 150mbps, so 2 of them get you 300mbps.
Pro and iMac have 3 stacks
