EHD firewire vs usb - which is better?

Hello Apple Fans,
I need to get an ehd for storing and editing iMovie projects and was wondering if a USB 2.0 drive with 480 Mbps is going to be fast and reliable enough for the job?
Many thanks for any help.

I hate to have a difference of opinion with Kirk ..who knows everything about QuickTime!
But although USB 2.0 is fast, it doesn't have the sustained file transfer speed of FireWire. It carries data in bursts, rather than as a continuous stream. So although you can transfer files OK with it, it's NOT really fast enough for editing movies which are stored on that external hard disc.
And if the hard disc is connected to a Mac via USB, then although there may be a FireWire socket on the hard disc too (..supposedly for connecting your camera to..) you won't be able to send video from the camera to the hard disc and use it within iMovie, because there is no connection between the FireWire circuitry and the USB circuitry: so, as Karsten explains below, your Mac won't know that a camcorder is connected to the external disc!
You say "..I need to get an ehd for storing and editing iMovie projects.." ..you'll be able to store your projects on a USB-connected external disc, but you won't be able to edit successfully using a USB-connected external disc.
You could import to your internal disc, edit there, then transfer the finished movie to the USB disc, but USB is too slow for editing with.

Connecting my iPod to my mac. firewire or usb, or both???

my new iPod came with a usb connector. my older iPod (3 years ago) came with a firewire connector. i still have the old connector. can i connect using either my new usb or older firewire connector? which is better? is there any difference? why didnt apple ask me if i was a mac or pc user when i ordered it, so they could send me a firewire connector instead of the usb connector that they did send?
usb or firewire? does it make any difference? firewire must be faster right?
thanks for your help

sync? what do you mean?
Sync means to connect the iPod to the computer and load songs onto it.
It will update/sync only with USB.

I have a MacBook Pro (Retina) and a Sony HandyCam DCR-HC48 video Camera. The Sony only exports video via Firewire, which is not available on the Mac. Is there a firewire to USB or to HDMI adapter?

tyler57,
it would be better to direct that question to Gary Loftis, since my MacBook Pro doesn’t have a Thunderbolt port.

Connecting MAC Air to Projector - which is better, hdmi, vga or usb?

HDMI is thje preferred digital replacemnt for older analog video standards, which your other choices use. It offers far higher signal and definition quality.
Apple has an adapter that is used with your Thunderbolt port/ Mini DisplayPort, if yours is equipped as such.
I've not had a problem with this. It is a Belkin.

Which is better for usb camera between VISA and imaqdx in labview 2010?

i have done a program for usb camera to acquire images with imaqdx.
now i want to know which is better between VISA and imaqdx in labview 2010?
i didn't study visa before
thans for help.

VISA is primarily used to communicate with instruments via GPIB/TCP-IP/Serial/USB. In order to use easily VISA with an instrument over USB the instrument must adhere to the USBTMC spec. A camera is not likely to have this. Otherwise you have to use USB RAW, and that requires detailed knowledge of the data that is transmitted by the instrument. Manufacturers rarely give this information out. Normally they will provide a DLL to communicate with the instrument.
Thus, in your case, VISA is not going to be an appropriate API to use for a USB camera.
Out of curiosity, what prompted this question?

USB is better and faster

What USB 3.0 card should I get for early 2009 Mac Pro so I can connect the Drobo 5D? They say get CalDigit or Sonnet. Anyone have preference or experience with reliability. Trying to find which is better.

What USB 3.0 card should I get for early 2009 Mac Pro so I can connect the Drobo 5D? They say get CalDigit or Sonnet. Anyone have preference or experience with reliability with this. I am running Lion and Trying to find which is better as I know from experience not all cards are created equal. Thanks in advance for your help!

Running Moutain Lion on Early 2009, mirroring two Seagate Go Flex 2TB USB 3.0 Drives. Installed in Slot 4.
Using it primarily with VMWare Fusion for Virtual Drives. Windows, Unbuntu and other OS running really well.
HPT Support was responsive and very helpfull using the WEB Portal under the product page.
I have some comments and a suggestion:
Have you tried your setup with a SD/CF combo card reader (like the Lexar or Kingston FCR-H63)? Does the card appear on the desktop when first plugged in?
Did you need to fool around with any kind of power issues in installing this card in the x4 PCIe slot of the MacPro?
Suggestion. Have you tried one of the fixed in this article to cure the BT issues in MacPro 3,1?
Good luck.

Which is better,the Apple TimeCapsule or the WD MyCloud for backing up pixs and datas?

I am not too sure which is better for backing up my pixs that i have saved and dont want to lose them,am thinking which would be best for me to purchase?the apple timecapsule or the wd mycloud,i heard great things about both but not sure from someone who got experience,so could u help me out and tell me which is better and why?
thanks in advance...

Backup is backup. Doesn't matter how you do it, but that you do it.
Given the choice you posited I would choose the Time Capsule if you want to use Time Machine. If you wish to use third-party backup software then you can only use the WD. It comes with its own proprietary backup software. Or you can go another direction and avoid cloud/network backup which is very slow.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
     used to manage backups and to restore backups. Time Machine
     requires a backup drive that is at least twice the capacity of the
     drive being backed up.
3. Time Machine requires a backup drive that is at least double the
     capacity of the drive(s) it backs up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Although you can buy a complete external drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
1. Cool Drives
2. OWC
3. WiebeTech
4. Firewire Direct
5. California Drives
6. NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.

USB 3 vs USB 2 -> the importance of USB 3 depends on how much you use an external drive to read/write large files or large numbers of files. I once did extensive testing with USB 2 vs FireWire 400 & 800 with TimeMachine. It was no surprise that performing a complete backup with FireWire was significantly faster than with USB (or even a large backup such as after installing an OS update). But for those hourly (or even daily) backups the difference wasn't all that significant. Exporting a large number of photos or an iMovie to FireWire was significantly faster. Copying a copy word processor files it was almost impossible to accurate time the difference. For some the USB3 ports are a big deal. For me, not at all because I'm heavily invested in FireWire drives.
BlueTooth 4? Frankly, I can't say because the only thing I use BT for is my keyboard and mouse which the older standard is fine for. There are potential advantages - just as with USB3 - the question is whether your current/future needs align to the new standards. Again for me they don't.
As for the CPU difference - I've already indicated that unless you are doing high processor intensive work (such as 3D modelling or big statistical modeling) either processor has plenty of power. According to the benchmarks my new work iMac runs rings around my work 2009 Core 2 Duo 13" MBP. In my real world use of those two computers I never notice the difference. If I played 3D games on them I would.
I've already said that all but one of my refurbs looked new and from what I've seen of relatives and friends buying refurbs that runs pretty true. You aren't buying a new computer but on the other hand I've never seen a refurb that looked beat up. Most refurbs are computers that buyers returned within Apple's 14 day buyer's remorse period or were dead on arrival, a new one given to the buyer, and repaired.
I can't tell you how long a refurb MBP will last - no more than I can tell you how long a new MBP will last. But Apple warrants them for a year and lets you buy an extended warranty just as if they were new. That indicates the confidence Apple has in its refurbs.
Where do you get the idea that you can only put a 128GB SSD in a 13"? It can handle any standard 2.5" drive and there are plenty of SSDs in that form factor at 256GB and above. Yes an SSD is expensive compared to a standard drive but the speed increase is amazing and not just in booting up the computer. Installing an SSD on my 4.5 year old iMac gave it another year of live. Installing one in my work MBP was like getting a new computer. I wouldn't consider buying a new computer without one.

Journaling External FireWire and USB 2.0 Hard Drives?

I have several FireWire and USB 2.0 Hard Drives which I have always formatted as "Mac OS Extended (Journaled)".
I have been told that journaling is a waste of time with external HDs and, if anything, will slow them down slightly.
What is the general consensus on this forum?

Thank you for the swift response Malcolm.
I better explain why after all these years I am having doubts.
I am awaiting the delivery of a new piece of kit - a Western Digital HD TV Media player. Basically, you put your hi-def videos (H.264) on a USB 2.0 HD, plug it into the media player which is then plugged into your HDTV.
I have got hold of the manual which says that the supported USB file systems are "FAT32, NTFS and HFS+ (no journaling).
So I was wondering whether I will have to format the HD without Journaling to make it work?

Firewire and USB

In my process of researching to buy a new Intel Macbook I've discovered that there is only one firewire port, two USB 2.0 ports, and no pcmcia port.
Here's my problem. This laptop will replace my old powerbook that I use for recording audio. I need one bus for audio to enter the laptop and one bus to access my external hard drive to write the audio. I currently have a firewire bus card in the pcmcia slot and use the firewire port for the other bus on my powerbook. This optimizes the amount of data that Logic can process. My worries with the new macbook is that USB 2 is typically slower than firewire. So using the firewire and USB 2.0 ports may slow me down. I know the old powerbooks with USB 2.0 had issues with the USB 2.0 bus being really slow compared to PCs. Was this problem ever fixed? Does anyone have any experience with this or any suggestions? I know I could just buy a macbook pro, but I really didn't want to spend that much money.

Actually there's more than just another FW port. It's a FW800 port, ExpressCard/34 expansion slot, faster and better GPU with more VRAM, faster CPU, more RAM, bigger hard drive, and higher resolution screen.
You're buying a business computer. That means you are making an investment. You can write off the investment which reduces taxes. Doesn't it make better sense to be dollar wise rather than penny foolish? Over a three year write-off period you're bartering over $250 per year.
The MacBook has no expansion future whereas the MacBook Pro does.
However, this is ultimately your decision. All I wanted to do was point out the benefits of the MBP over the MB. I should probably stop here lest I sound like I'm making a sales pitch - which I'm not. I own a MacBook and two MBPs. I like them both.

Which is better to sync, wifi or iCloud?

I heard that you shouldn't sync with itunes and icloud. Which is better, and how do you set that up?

Where did you hear you shouldn't use these?
You're comparing apples and oranges. Wifi sync is a way to wirelessly sync with iTunes on your Mac or PC. This includes content that you've purchased, content that you've ripped from your own CD collection, as well as things like playlists, song ratings, etc. This is just to replace plugging in your USB cable as you've always had to do in the past.
iCloud is a way to store some of your content on Apple's servers and retrieve it on any iCloud enabled device. Note this includes only content you've purchased (music, movies, tv shows) or content you've created using iCloud-enabled apps like Pages, Numbers, or Keynote. iCloud doesn't let you sync "metadata" such as playlists, song ratings, etc. if you add a song to a playlist on your iPhone, it won't show up on that same playlist on your iPad, Mac, or PC because you use iCloud. It only gets moved on those other devices after you sync. iCloud also provides a means to keep calendars, contacts, notes, and reminders the same across multiple devices. Finally, iCloud let's you backup your device to the cloud instead of to your Mac or PC, which is handy feature as you don't have to worry about losing your backup should your Mac or PC fail.
You can choose to use iCloud and not wifi sync, or use wifi sync and not iCloud, or use both or use neither. They are independent of one another and provide different functions.
Personally, I use both. I wirelessly sync so my iDevices are up to date, and I take advantage of iCloud for my backups, calendar, contacts, etc.

Which is better, charging the battery at a higher amperage or lower?

I just bought a 3rd party adapter to recharge my Touch via the AC outlet. I have an application on my touch that gives me the status of my battery. When I plug my touch via USB, the charging amperage is 500ma but when I use the AC plug, it says 1000ma. So which is better for longer battery life?
