Are there any signs pointing to the integration of USB 3.0 into the upcoming iPhone 6?
so far none
There is no benefit to USB 3.0 in an iPhone. USB 3.0 is faster than the iPhone's flash storage... so there is a bottleneck that would make USB 3.0 implementation a waste.
I don't believe you. If that is true, it's only because they have chosen to put crappy flash storage in the iPhone. If they want to implement USB 3. They can. Personally, I'd rather see Thunderbolt or FireWire 800.
What 1080p said is true, it's been known for some time now. Actually, I don't think the current flash can even saturate USB 2.0. Until they add faster storage, they won't update the spec.
Firewire is pretty much retired, and Thunderbolt is still too expensive and is still mostly existing on Macs. There are a few Windows machines with them, but not the majority.
Welcome to 2014, Apple. We've seriously got people with 128 GB iPad's that are transferring files at less than USB 2.0 speeds? That's really kind of pathetic on their part.
And for the "128 GB" comment, try transfering a single 4GB file on to a flash drive, it will take days if ever. Even when selecting a million pictures that are 4GB the speed will never even match USB 2 let alone USB 3 speed.
Flash tech not so bueno.
True, and at the same time sooooo sad.
Not sad at all. Heck, the iPhone's flash storage is slower than USB 2.0.
Yes, theoretically they could make it faster, but at the cost of battery life.
Take one of those high performance USB 3.0 flash drives and start a long copy operation to them. Feel the drive once it's been copying for a minute or so. Notice how warm it is?
Fast flash memory is a power hog.
Did not know this, and probably why they elect to use the slower storage.
That's just the speed of small amounts of flash storage. Don't confuse it with an SSD.
Only benefit of USB with a smartphone would be faster charging if the device allows it.
Why on earth would you care about power drain when it's copying files???
Are you saying that a device could not charge and copy files at the same time ??? Interesting
Its profit actually. Fast memory costs more.
I've got a fast usb3 flash drive. Running it on usb2. A 4gb file will take a couple of minutes to transfer. Certainly less than 3. I don't believe it's the fastest flash available, either.
Fast speed will also take less time, so it's not just the speed itself.
It's not "power drain when copying files". It's power drain when writing to the disk. The iOS device writes to its flash disk constantly during operation; you don't want these writes to use a lot of power.
I have this thumb drive..takes no more than 30-45 seconds to transfer a 4GB file. It all comes down to the transfer rate that it can handle, which this one kicks ass at.
Are you trying to say that faster flash memory uses more power ?
If your talking about the iOS device writing to the flash memory once the USB cable is disconnected , those writes are not over USB .
I maybe missing something here . Feel free to give more details.
No. Please no. Leave things alone. I don't need anymore damn apple cables.
How much stuff and how often are people copying things back and forth?
Whats the model, I want it.
I forgot I could connect my iPhone to my laptop.
Hasn't crossed my mind since 2011.
I can't think of a single reaon why you would want to these days?
Unless you are sideloading movies that you have 'aquired' onto it maybe?
Getting a full iOS copy rather then an OTA patch is a reason someone might want to plug into iTunes.
If you have music you didn't buy on the iTunes store, and don't want to use iTunes Match, you still have to connect the phone to your computer to sync that music.
First, assume I've obtained everything legally and mostly not through iTunes:
-Music (cd rips)
-Video (media version found on discs)
-Podcasts. You could always do this on the phone but until recently that was extremely cumbersome.
-Syncing pics. I have 2 other much better cameras and sometimes I want to take those picswith me. I also like to have my iPhone pics saved to my computer and backed up.
That's assuming faster memory even exists for the form factor and power consumption required during development. Also, don't forget that the flash memory typically used in mobile applications is self-contained and includes the storage controller. USB 2.0 can sustain 40 MB/s throughput and for now, that can more or less saturate eMMC.
Mind, I do hope the Lightning spec has provisions for USB 3.0 even if current devices only does USB 2.0. Not having it is somewhat short sighted (or just a plain money grab). Sooner or later, flash memory used in mobile devices will be able to sustain sequential write speeds considerably higher than 40 MB/s.
I rarely connect my iOS devices to the computer via cable but the few times I do (usually to do an iTunes backup/restore since it's faster than iCloud), faster storage and interface would have been quite useful.
