I notice when they first came out they were 500GB and 1TB options.  Now there are 2TB and 3TB.  Is there a fundamental difference in how they operate? Perform?

 

If not, and I were to pick up one of the older ones that had the 500GB drives.  I could theoretically put one of these in there, yes - http://www.newegg.com/Product/Product.aspx?Item=N82E16822136893

 

thanks!

    the newer time capsules have the following features you won't get by replacing the drive in your old unit

     

    1) the newest units have 2.8 x the maximum power output over the previous model (392mw vs 192mw)

    2) the newer time capsules have certified/official/final 802.11n code the older ones were draft n 2.0

    3) the last two versions of the time capsules have 3 x 3 spatial streams, meaning you can do 450 mbps over 5ghz

    4) the newer time capsules might have simultaneous dual band, your old time capsule might be one of the older  ones that made you pick what frequency to use

    We use a 2 TB. model. Would thatbe able to use the 392 mW as well? Is that only for 5 GHz?

  • bobsbarricades Level 1 Level 1 (0 points)

    Very interesting guys.  What does the increase output do and why does it matter?

     

    Also - I'm not terribly interested in speed - but I did just realize it'll save me 200$ my way.

     

    Weren't they always dual band?  I hate how apple does this to me every time... I wait to upgrade and then things aren't compatible anymore..

  • rigormortis Level 2 Level 2 (225 points)

    the newest "md031" time capsule has a maximum power output of 392mw versus 192 mw for the older model

    that might give you better range or a faster speed at the same distance as the older models. i told the internet this and those ifixit mac insider guys finally realized what a blunder they made reporting "no new features" and promptly ripped me off and didnt credit me for my airport discovery!

     

     

    the time capsules might of been always dual band but only the last two were simultaneous dual band.

     

    with the oldest ones you had to choose if you wanted 2.4 ghz or 5 ghz but you couldn't choose both of them at the same time, the recent time capsules have 2.4 and 5 ghz at the same time

     

    i'd say if you have an older time capsule find out what model it was and if it was older tehn the md340 then sell it on amazon for $100 to $150 and use the money to buy the newest model

     

    and then thre was that whole mess back in 2008 or 2009 where all the time capsules were only lasting 18 months because of a probblem with its power supply?

     

    if you already have a "md340" time capsule and if you wanted the latest "md031" model then i would reccomend buying the newer model from some place with a good return policy like amazon and testing it in your house and to see if you think the improvements is worth the $299, and if it is you can keep the newer model

    and then sell the older model

    Emphasis on might.

     

    We tried a new Time Capsule at a neighbor's house and it perfomed virtually identically to his 3rd generation version. Apple is extremely quiet about advertising any improvements on the new version....probably with good reason.

     

    Time will tell.

  • bobsbarricades Level 1 Level 1 (0 points)

    this is very interesting. 

     

    I don't have the money either way right now but...again... I'll sit and wait.  Are these new simultaneous dual band Capsules carrying one HDD or 2? 

     

    Thanks guys!

  • rigormortis Level 2 Level 2 (225 points)

    i got one of the newer time capsules as a gift

     

    and i figure the increased power output probably won't help 5ghz going through walls and doors, but i feel it might reduce the need of extenders tho..

     

    if you want to further nitpick about these improvements is theres another page in that fcc printout that has me scratching my head

     

    both the airport extreme (a1408) and time capsule (a1409) have the following power levels

    802.11b 257.04mw 802.11g 307.61 802.11n 257.63

    802.11a 326.59mw 802.11n 20 mhz 337.29 802.11n 40mhz 392.64

     

    but check out the difference in peak gain of the antennas


    frequency range 2.4 - 24.83         antenna one 1.41 dbi |    antenna two 2.33 dbi | antenna 3 1.83 dbi

    frequency range 5725 to 5850     antenna one 1.72 dbi  |   antenna two 2.97 dbi  | antenna 3 2.67

     

    now compare this to the time capsule

     


    frequency range 2.4 - 24.83     antenna one 0.1 dbi |  antenna two 0.27 dbi     |     antenna 3   4.32 dbi

    frequency range 5725 to 5850  antenna one 4.38 db|    antenna two 0.81dbi    | antenna 3       3.09 dbi

     

     

     

    wouldnt they be teh same gains on both the time capsule and the airport? why are they different

     

    i think the bottom line i want to make is if your going to upgrade your time capsules make sure its covered by

    a computer's applecare plan, i know its like 150-250 dollars for applecare but the 1 year warranty on the time capsule is really short. and i still can't friggen copy my apple core duo 2006's time machine to it

  • Inkjetmac Level 1 Level 1 (125 points)

    Having the same power and higher antenna gain would mean the TC has better range than the extreme. We noticed that in older models, too. We thought this was because the case of the TC is bigger, providing more room for the antennas.

    Apple should have used external antennas. Perhaps it wouldn't look as good, but the range would certainly have benefitted. Some of the competitors have much better range.

  • bobsbarricades Level 1 Level 1 (0 points)

    what are the time capsule competitors!  I couldn't find any. (or do you mean airport extreme competitors?)

  • Inkjetmac Level 1 Level 1 (125 points)

    Yes, the range of wireless bases can be much better. Of course generally they do not provide backup facilities. If Apple would use external antennas they could have backup facilities *and* good range.

    are there any ways I can hook up wireless routers that will allow me to plug in my firewire external hard drives?

  • Bob Timmons Level 10 Level 10 (87,010 points)

    Firewire drives are known as "external" drives and must be connected directly to a computer.

     

    They are not "network" drives that connect to a router.

  • bobsbarricades Level 1 Level 1 (0 points)

    so question.  If I got a new TIme Capsule (2TB) and had a 750GB internal HDD, and 2 500GB external firewire drives, would I be able to use TIme Capsule to backup all my stuff on my internal using Time Machine including the data on the firewire externals?  It would stay there and not get deleted just because my external drives weren't plugged in right?

     

    Would I then be able to make those two 500GB external drives a RAID (mirror) using Disk Utility?

    Yes, if the FireWire drives are connected directly to the Mac, Time Machine will back up both the Mac and the attached FireWire drives if you elect that option in Time Machine preferences.

     

    It would stay there and not get deleted just because my external drives weren't plugged in right?

    Correct as long as there was plenty of free space on the Time Capsule disk.

     

    Would I then be able to make those two 500GB external drives a RAID (mirror) using Disk Utility?

     

    I haven't done this and only answer questions regarding things that I've done myself. So, you'll have to wait for another user, or perhaps start a new post for that question since things are really "buried" in this post and I doubt that it will get many new views.
