USB vs FIREWIRE vs ESata II RAID indirect FCP question

Question: I have been posed with a question from my purchaser... Why doesn't USB transfer my video files faster than Firewire (when USB is rated at 480Mbs and Firewire 400 at, well, 400Mbs) and I already know that firewire drives all "linked" spend too much time talking to each other, so the SATA drive is faster...
Anyway, can anyone tell me exactly why outputting via USB is not faster? I read something on former posts about "short bursts"...but I'm trying to keep this guy from buying cheap maxtor USB drives...and let me build the eSata that I know will work faster with my FCP files
Thanks

Hi Mark,
This is common question. Check out this site, I think it explains the difference between Firewire and USB quite nicely. http://www.usb-ware.com/firewire-vs-usb.htm
Basically, Firewire flows better and is constant, USB is not. So if you're going to do any capturing to the HDD's you're going to want Firewire.

    How can I connect my new MacBook Air to a LaCie hard disk with TIme Capsule backup from my old Imac? LaCie has USB 2.0, FireWire and eSata ports.

    You can direct connect your MBA to the LaCie via USB 2 cable.  If you have an Apple Airport Router you can USB connect the LaCie drive to the router and then use Airport Utility to configure it.  Time Machine can access it either way.

  • Full backup ( ~ 1 TB ) using external HD - speed USB vs. Firewire vs. eSATA  - what are relative speeds - how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)_

        Hi All,
         I'm trying to resume regular scheduled Full backup ( ~ 1 TB ) of drives using external HD (to allow off-site redundant backup storage) .
         What are relative speeds of USB vs. Firewire vs. eSATA ?

    Adding a USB 3.0+eSATA PCIe card, which The hatter mentions, is the best solution that I've found. See http://eshop.macsales.com/item/CalDigit/FASTA6GU3/. The card is not cheap, but the USB 3.0 works flawlessly (which can't be assumed; ask me how I know) and the eSATA connection allows booting from the connected drive. Grant Bennet-Alder's point about HD speed is important to consider; in addition, the size of the individual files being backed up and where on the backup disk they're going will affect overall transfer speed. For example, using the USB 3.0 connection on that CalDigit card going to a Toshiba 3TB external, the transfer rate for a big file (say a virtual machine file) from an internal SSD boot drive was about 145 MB/sec while a bunch of little files might drop to 30 MB/sec and both rates decrease as an inner partition on the external is used. All told, a nearly 700 GB backup took under 1.5 hours. Using a HD as the source added almost an extra hour, though a WD external was used for that. Using a WD green drive plugged into this http://eshop.macsales.com/item/NewerTech/FWU3ES2HDK/ with an eSATA connection took about 2.5 hours also, but that was bootable whereas the USB 3.0 connection is not.
    Another point to consider is that USB 3.0 is ubiquitous on PC's now so there's lots of price competition for externals; not so much for eSATA externals.

  • Media storage: usb 3.0 vs eSata, solo or RAID?

    media storage: usb 3.0 vs eSata, solo or RAID?
    I need to build up my media storage on my Win 7 Pro 64 bit edit Workstation for CC 2014.
    Any ideas from all of you much more experienced editors?
    Thanks,
    Vern

    Then a single drive whether USB3 or E-sata will work. The only difference between them with single drives is latency. E-sata has a lower latency than USb3. Outside of that the speed is the same for mechanical drives.

  • Firewire cable & eSATA cable

    How may pins does my late '08 MBP have for the Firewire connection? I'm on Monoprice's site trying to order a cable, but there are so many choices, that I'm not certain what I need.
    Also, I have a LaCie 2T NAS that I'm currently using through ethernet connection to AEBS, but I was thinking of connecting it straight to my MBP. The LaCie has an ethernet, eSATA and USB connection and I was thinking of using the eSata connection, but I obviously don't have that on my MBP, so would I need a cable with firewire on one end and eSTA on the other, or do I need to purchase a firewire/eSATA adaptor?
    I searched the forum but did not find the answers to my question.
    thanks
    Paul

    MBP firewire 800 is 9-pin. And I have seen firewire-to-eSATA converters by FirmTek (they have a yahoo store) in the form of powered hubs sold as the "SpyderHUB".

  • Which external HD type (firewire or esata)

    Which external HD type (firewire or esata), is the best for Rendering video used with a Mac book pro?
    ive heard of esata.....is this available as a connection type on a macbook pro?
    any and all comments welcome , thank u.

    Thank you so much for your input here - these boards/forums are so great for questions and answers for a new to be mac user like me.
    I will be getting the G-Drive 500GB drive quad interface.
    It has firewire 400 and firewire 800 and USB and esata connections. It comes with a firewire 800 cable.
    I think I may just skip the esata expansion card and edit/capture/render on this external drive using FW800.
    thank you again.
    cheers,

    I am wanting to connect two Firewire cameras and an esata external drive simultaneously. Does an expresscard exist that can help me do this??

    So you are looking for an express card with 3 firewire slots? The best I've seen is 2 firewire, 1 usb.

  • 20" Cinema display with USB and firewire ports not working

    I have a new 20" display and was wondering why my USB and fire wire ports at the back are not working. I have an external drive that is powered hooked up to the fire wire port and a no powered piano keyboard to a usb port.
    Any help please

    Verify that the display’s USB and FireWire cables are firmly plugged in to the
    computer. Do they show in your profiler?
    Try different ports in the computer.
    Verify that your computer ports are working with other known problem free device.

  • What is wrong with my 30" Cinema Display?  The USB and FireWire ports still work, but the screen is pitch black. When you plug it into the computer, it detects that it's a Cinema Display.

    When you plug it into the computer, it detects that it's a Cinema HD but the screen is pitch black.
    For some reason, the USB and FireWire ports still work.

    If you shine a really bright light directly into the screen can you then see a faint image on the screen? If so, that would indicate the backlight has died (hardware failure) and the unit needs repairing.

  • Daisy Chain USB To FireWire?

    Hi all.
    I'm not really sure where to post this, so any suggestions about a better place would be great. Anyway, here's my question.
    I do a lot of work with photos, and they take up a lot of hard drive space, so what I'm planning to do is this: I'll buy a big external hard drive with lots of connections (1 USB, 2 FireWire 800, 1 FireWire 400). I'll also buy a smaller external hard drive with much less in the way of connections (1 USB only). The big drive will act as my main storage drive, with all the files for each image included on it. The smaller drive will act as the bakcup drive, with the top 20% or so of my best photos in only a compressed format on it. I want the smaller (backup) drive to be as cheap as possible, as I don't have much of a budget at all. Here are the two drive selections I've made: big drive:
    LaCie Big Disk Extreme+ Triple
    Small drive:
    WD Elements
    Desktop
    So, here's the question: I know that you can daisy chain FireWire drives that have more than one port together, like this:
    A cable from FireWire port on Drive A to FireWire port on Drive B, then a cable from another FireWire port on Drive B to the FireWire port on computer. I know this works (right?).
    But I don't want to have to spend more money on Drive A (the backup drive) so that it has a FireWire port. Since Drive B (the main drive) has a USB port, I thought I would run a USB cable from Drive A to Drive B like this:
    *Setup 1*:A cable from the USB port on Drive A to the USB port on Drive B, then a cable from the FireWire 400 port on Drive B to the FireWire 400 port on the computer.
    Will setup 2 work? Will the data from Drive A make the crossover from USB to FireWire? If not, I suppose I could also use this setup:
    *Setup 2:* A cable from the USB port on Drive A to one of the FireWire 800 ports on Drive B, then a cable from the FireWire 400 port on Drive B to the FireWire 400 port on my computer. Will this work better? Do USB to FireWire 800 adapters really work?
    So, basically, all I really need to know is whether or not Setup 1 will work, and if it doesn't, whether or not Setup 2 will. Also, if anyone has any info/reviews/stories about the two drives I've selected, I'd love to hear that as well.
    Thanks so much in advance for any help I get. Sorry about the long post; I hope it made sense.
    Thanks again.

    Thanks for the response!
    What about Setup 2, though? Does someone sell a USB to FireWire Converter?
    Nobody has heard of a USB to FireWire converter that works.
    The first example you gave would require a USB B to USB B cable or perhaps a "gender bender". Both of the drives you're looking at seem to still use the original full-sized USB B port, while many have gone to the mini-B. It wouldn't work anyways since both are USB slave devices. USB was never designed to daisy-chain.
    Why can't you just connect the USB-only device to the USB port. If you're strapped for ports, then maybe a USB hub. You wouldn't even need a powered hub if you have a few low-powered devices and this external drive which doesn't use bus power.

  • S-Video to USB or Firewire Converter

    I'd like to use the S-Video output on my VCR to input into my Mac via either USB or Firewire. Is there an affordable (less than $50) converter that can do this job? I can use either iMovie or Final Cut.

    Unfortunately there is no under $50 converter that will do what you want unless you can find a 'deal' on eBay or Craigslist.
    The Canopus ADVC-55 will do the job and is about the least expensive converter available, but it goes for $200. AND, if you were to consider that expense I'd really suggest the ADVC-110 instead - at the same price it gives you bi-directional conversion, not single direction.

  • USB to FireWire converter cable, will it work?

    There are a number of sellers on auction sites selling USB to FireWire (4-pin) converter cables. Will these work with iMovie in respect of connecting my Samsung MiniDV Digital (tape) camcorder? The seller claims they will, but I am skeptical based on what I've read on the internet - so I thought I'd ask the discussions for their advice/experience...?
    FYI I'm using a 13 inch Alu MacBook prior to the inclusion of a FW port...

    Despite Niel's great suggestion, the bottleneck is the USB connection into the Mac; even though it's possible to plug a FireWire adaptor into that USB/ExpressCard socket, the ultimate connection (..or combination..) has a USB specification.
    USB delivers burst of high speed data, not continuous hi-speed data, which is what FireWire offers, and what miniDV camcorders send out. The camcorder won't be able to make proper contact with the Mac at the far end of the chain, so the computer won't "see" the camcorder, and nor will the camcorder be able to tell the computer "here I am, sending you a digital video-&-audio stream".
    The connectors will all physically fit together ..just as you can physically pour paraffin (kerosene) into a car's petrol (gasoline) tank ..but that doesn't mean that the car will actually run with a tank full of kerosene ..or diesel fuel, for that matter.

  • Is there a USB to Firewire 800 adapter?

    Hi,
    I've seen that I can get a USB external hard drive for much cheaper than a firewire800 one so was wondering if there is an adapter to plug a usb hard drive into the firewire800 port on my MBP so I can save my USB ports?
    Thanks in advance
    Simon

    No. No adapter exists to connect USB devices to a FireWire port; hubs which provide both USB and FireWire ports don't transfer any data between the interfaces.
