    Hello, im kinda stuck!
    I need a new router and a new external hdd. thinking about getting a Time capsule.

    Im stuck in the decision because i can't find a good answer to how the real world transfer speeds are if i want to use one of the new AC Time capsules as external storage using AC wireless on my 2013 mbp retina.

    anyone with the latest firmware+mavericks and a 2013 mac with ac wireless wanna do a couple of blackmagic speed tests for me?

    That way at least i can compare to my current old usb 2.0 external drive :)

    Or maybe just some timed test for a 4gb file or two?

    I'm guessing that it will be the Time Capsule's processor that's the slow point, not the wireless throughput. I'm only guessing, because I have only a 1st-gen Time Capsule (yes, from 2008), but I was curious so I tried the Black Magic speed test on it. The TC is connected via Gigabit Ethernet to my iMac (through a Gigabit switch).

    I only get about 15 MB/s write and 10 MB/s read, according to Black Magic. This fits with what I've observed with iStat Menus: that when a Time Machine backup is in steady state, I see a throughput of about 10 or 11 MB/s.

    It's fast enough for a lot of things, but not what I'd call fast! I haven't heard of the newer TCs being any faster, but they certainly could be.

    5th gen (newest) TC with BlackMagic:

    * I get 29MB/s write and 16 read over an 802.11ac (late 2013 iMac 27") connection (with actual transmit rate of 1300).
    * I got similar performance with a 2013 MBA (802.11ac) when further from the router, indicating that the bottleneck has more to do with something other than the 802.11ac connection.

    On the other hand, I just tested via an MP3,1 on a wired connection and got 45MB/s read & write....so something must be happening with the wireless aspect.

    The 2TB HD on the TC is about 1/2 to 2/3 full.

    Hope this helps.

    that does help, a bit slower than the usb 2.0 7200rpm drive i have... but I'm guessing it could be about the same peed as using a 5400rpm portable usb 2.0 drive?

    any experience with playing 1080p movies from your time capsule on your mac? or maybe streaming with beamer to an apple tv? :)

    sorry, i've never streamed content from the time capsule. 25-45MB/s doesn't seem very high.

    I just streamed a 1080p project I made in iMovie and saved as a movie file from my AC AirPort Extreme. Attached is a 5400 USB 2 hard drive. No noticeable degrade in quality or performance. So if a USB drive attached is fast enough with writes of 21 MB/S and 12 MB/S of READ, then I am sure the Time Capsule will be more than plenty!

    Even BluRay only requires a few MB/s of bandwidth. 20 MB/s is more than plenty for several streams.
