How fast is the USB transfer rate?

Hi all,
I am about to switch from Prophet to Polaris. One very annoying problem of the Prophet is the extremely slow USB transfer rate (I guess it supports USB 1.1 only) - I have to transfer large stuff to the memory card directly.
How does the Polaris perform in this respect?

Polaris work on usb 2.0.
Bye

If you are still interested (last weekend I had to transfer few files):
Tested with a 1GB Sandisk (was in package)
~0,5MB/s USB (Vista 64-Bit, 333MB moviefile transferred in 10:47min)
~100kb/s Bluetooth (Macbook OsX 10.4, 3MB moviefile)
so keep your cardreader
(Maybe the Sandisk isn't the fastest, but I believe that the phone restricts the transferrate. So USB 2.0 is just a marketing trick)

Damn, too bad So this means you cannot practically use your device as a USB stick with tools like CardExport...

If you buy a MicroSD card from Sandisk you get a USB cardreader as well.
This is the fastest method to transfer large files from a PC to your memory card.

That's exactly what I did an hour ago Still, it would have been much easier if I could transfer the data directly through the device...

Kingston Class 10 Micro SDHC Yes or No

I am about ready to buy a 16 GB class 10 micro sdhc for my Nexus One. Any ideas if this is a good card. Will it be totally compatible? And will I be able to transfer at the advertised speed? Does anyone have one of these?
http://www.newegg.com/Product/Product.aspx?Item=N82E16820139121&Tpk=SDC10/16GB

I think a class 6 is enough. Don't see a need for a class 10.

If HD recording ever gets adapted....or divx playback I'm sure the extra speed wouldn't hurt. The question is whether or not to nexus 1 will utilize it.

My class 6 micro sdhc card is only transferring at 2 MB/s through the data cable from phone to computer and vice versa. Either my card is taking a **** or something is wrong, it's definitely not 6 MB's.

So if I can pick up a class 10 micro sdhc and actually being able to copy music onto my sd card mounted in my phone at 10 MB/s I would be really pleased.

I just pulled the my micro sd card out of the phone and plugged it into a micro sdhc to usb adapter, and I transferred music onto the card through the adapter and it transferred at 6 MB/s no problem. So there is nothing wrong with my micro sd card. WTF Has it always been this way.
What I mean is: while the card is in the nexus and when you transfer music to the phone through the data cable, is the nexus only able to transfer at 2 MB/s? Through the Data Cable?

Yup... I've noticed this too. It was the same on my G1. The card is capable of 6mb/s but the phone can only do 2mb/s through the usb...

That really is a bummer, I don't know why in the hell I haven't noticed this before. It really doesnt matter to me how fast my sdcard card is then. Because I never ever remove it from my phone. So a class 2 is pretty much all you need because that is the only speed the phone will ever transfer at.

Unless you're rooted and run Apps2SD... but yeah, I'm unrooted on my N1 and plan on staying that way and I don't understand it either. Maybe there's a way to speed it up with a software update?

i get a steady 5.6...

Let me get this right. You have your micro sdhc card in your phone. Then you plug the the usb data cable into your phone, then you mount the phone to your computer by the pull down menu on your phone, then you can transfer music to your sdcard at 5.6 MB/s? Are you sure about that? And you have to be able to transfer music off of your phone onto your computer at the same speed I assume.
The reason I am mentioning all this is I partition my sdcard to 3 partions fat32, ext3, and swap. So another words I had to transfer everything off of my sdcard, and transfer it back on after you created the partitions. And if you have 6 gigs of music this can take a very long time. Then I formatted my sdcard again for 1 partition and had to do everything again. At 2 MB/s that is a very long wait.
I guess I could of just pulled the sdcard from the phone and plugged it into my adapter and transferred at 6.0 MB/s. This sucks you would imagine the nexus could do this np.
It's amazing you can do it at 5.6 MB/s to your phone. Maybe you got a better version of the Nexus than I did?

Don't forget, there are two sides to the issue, the phone side and the computer side. Perhaps you could try another computer? I average 5.5MB/s from my Linux workstation.
Are you going through an old USB hub or direct to the computers ports?

Direct to the computer ports, and I am running windows 7, maybe I should try my ubuntu pc.

The phone's USB interface might be the limiting factor; when the phone is communicating directly with the SD card, it may be able to use its full potential. This would matter when you're recording video or using Apps2SD. Meaning that class 6 cards aren't necessarily pointless.
Also note that class 6 means 6 MB/s write speed, not read speed (as has been kind of said above - just waned to make it clear) - if you're reading it at 6 MB/s, that doesn't necessarily mean it's working right.
I don't have one to test with, sadly.

What I wanna know is where are the 32Gb Micro SDHC cards??

I have a 16GB a-data micro SDHC transferring via usb at speeds between 2-3MB/s
when i put the card in a card reader instead of the phone, xfer speeds are between 5 and 8MB/s
I'll try copying files to SD via wifi and bluetooth. if either of those are faster than 2-3MB/s, then the usb may be the bottleneck.

Are you guys benchmarking , or just going by screen stats ?

dang i didn't know they even made class 10.... I bought a class 2 16gb when they first came out, it just died actually so i'm waiting for sandisk to replace it. I've considered a class 6 but i don't see the point with 32gb cards coming out soon.
I've seen pre orders for late april on the 32gb's. other then that you can get one now if you import it from asia.

I am just wondering exactly what speed the Nexus One is capable of transferring at? Cause I can see alot of people are having the same problem as I am having with higher class sd cards. I know for a fact my class 6 sd can transfer at 6 MB/s and it does when its not in my Nexus One, so it's either the Nexus or the Data Cable that is eating the other 4 MB/s, cause I am only cable of transferring at 2 MB/s and no more.
Now when I talk about transferring I am solely talking about transferring music or data off of my Nexus to my computer and vice versa. I want to think it's just my Data Cable. But I wish I had this answer, I will today for sure.

Now is there a low speed Data Cable, maybe that is what Google sent me a low speed one, and maybe this 1 penny high speed data cable might solve me some problems.

Super Slow USB Transfer Speeds

Has anyone noticed the super slow file transfer speeds one this phone? I just tried to copy a movie over to the phone that is about a gigabyte in size and on my other phones it would usually take a few minutes at most but this phone has been saying "calculating" for several minutes now without any data transfer happening yet.
I have the phone on disk drive mode so I would have thought this wouldn't be doing anything weird like converting the video file on the fly during transfer or anything. It should simply be copying the file over but it doesn't look like it's happening.
This should be a simple feature but it's not working for me at all.

Works fine for me. Much faster data transfers than my DHD.
Of course, I've been moving files via a Mac, maybe there's an issue with Windows + OneX file transfers? Hopefully someone else can confirm.

Speeds have been average for me when compared to the E4GT. These 2 phone are still a faster transfer then my old nexus S. I would say the speed to transfer is roughly 5 min for a 700 mb film. I don't know if thats fast or slow really though.

About 12 ish minutes for 6gb of music. Not bad at all

might want to try a usb port on the back of your computer, or a different cable.

HTC USB Cable
Are you guys reporting fast file transfers (or at least average speed file transfers) using the usb cable that came with the phone or another micro usb cable? This morning when I tried to copy that movie file I was using the micro usb cable that came with my Moto phone (which I thought would be fully compatible) but got those really slow speeds which seemed like it wasn't transferring at all.
My HTC One X micro usb cable was left at the office so I didn't have it with me at the house so I couldn't try it. Now I am at work I guess I can try it with another large file but do not have the movie file I was trying to copy this morning with me.

I notice a change iin file transfer times on my HTC Sensation since upgrading to ICS.
I even tried using TeraCopy, but the time are just as abysmally slow - it definitely wasn't this slow before.
Am thinking to try taking the SD out of the phone and copying directly to that to see if there is any difference.

Yep, that worked, copied to the direct to the card via a card reader very quickly.
I did however choose to fix the bad sectors when that dialog came up, not sure if that helped.

Why the cable could slow down the transfer?
I just bought two of this cables: http://dx.com/p/designer-s-flexible-usb-charging-data-cable-for-htc-174cm-length-73860
And with one of these I sometimes get connection to the computer and with the other connects... but really slow, les than 1Mbit/sec.
Could it be a bad soldering? Could it be that the cable is flat? Could it be that some endpoint is not connected inside the cable?
The original HTC cable is flat: http://www.htcaccessorystore.com/uk/p_htc_item.aspx?i=196200&phone=196001
I must add that if I use the OEM microUSB-USB cable works perfect.

Slow file transfer when using mass storage mode

I am using SGS2 with Restruction ROM with Fluxi Kernel and transferring files to external SD (Samsung Class 10) through mass storage mode and it is extremely slow (less than 1MB/s even when large files). Took out the card and tested with card reader, it can write more than 20MB/s.

The speed is limited by weakest point in the system. Check USB cable, port and other end device, too.

Previously I got no problem with Gingerbread (CheckROM). Same port, same cable.

The reason I post here is I got less than 10 post. Hope to find answer here anyway...
Edit: Solution Found: USE REMOUNTSD

Probably an easy question but, External Hard Disks?

Hi All
Finally been able to order a TF700 from Amazon in the UK, I'm off travelling around Europe at the end of next week and intend to take the 700 with me, my question is can I take my external 1TB drive with me and use it as storage (for films, music etc)
Thanks all in advance

Should be doable, although much depends on the power consumption of the drive -- I haven't got a portable model on hand to test it for you. A power-hungry model could either drain the battery too fast to be practical, or it may just be plain impossible to power it from the tablet, causing it to just bork out on you.
Obvisouly, a powered model would cope just fine,but that's not very practical when travelling, isn't it? I have read reports of people using external hard drives on the TF700 before, so I guess it shouldn't pose too much of a problem, though.
Off-topic: where are you going?

assuming you have the keyboard dock too, not only for the USB port but for the extra battery capacity too.
but my WD 750gb works just fine!
I'd suggest MXPlayer 'cause the stock apps suck at decoding divx and other random container formats.

Cool thanks, just ordered a Toshiba Stor.e Alu 1TB (ebay special buy) which is bus powered, should both be here on the 2nd so will plug it into the dock to check.
I am heading down to Spain as I have an apartment there then going to see where the mood takes me, I have 3 months off work (well I say off work, taking the Infinity with an RDP program and my iPhone so I can tether the data) that way I can still work from where ever I am!
The infinity + dock seems the perfect device for me, can carry it easily, brilliant battery life and the full qwerty keyboard.

I plugged a 500GB bus powered USB drive into the dock USB port and it works great!

My 2TB Western Digital MyPassport works just fine. I did format it to get rid of the silly software, though. Don't really notice any powerdrain at all.

I've somewhat accomplished this before with a 2-usb hard drive. The main usb port for transferring I plugged into the infinity, and I plugged the port for power into a portable external battery. It was recognized as another SD card on my infinity. It worked flawlessly when transferring 800MB+ files.

Yup. It works. Mine is WD 1TB, connected via USB of the dock.

I've tried plugging in a standard usb drive (8gb thumb drive) in the usb port before but I can't browse to it in the stock file browser,"external storage"just shows as empty. Do you use a special app for that?

I use a Seagate 2.5" external. It transfers fine and is recognized but playing videos using either mxplayer or bsplayer is imperfect. There is a lot of stutter. My imperfect solution is to rotate out video files on my device.

Not only is an external a great solution, and works perfectly with the dock. It also has a really nice transfer rate. I was getting over 20mb/ps transferring from my 128gb flash drive to the micro sd. I have yet to spring for a 128 sdxc for the dock, but it's on my list.

So far I tried:
- External usb 2.0 disks
- Wireless mouse
- Linksys usb to ethernet
- Usb sticks
The dock's usb port seems to accept anything: even ethernet that allows me to even use my Infinity in the basement of my house (only wired connections there)

Thanks for all the input folks, shall experiment with the dock and hdd when they arrive next week! Quite excited, like a big kid lol

Wow good info in this thread. I never even thought to try my external hd with my infinity dock. Will save a ton of time during file transfers.

I'm one of those people that traded in there TF201 for TF700... I know this was asked and answered early on in the TF201 threads, so I guess I just carried over from there and never bothered asking it again.

For those that care I also had success with a USB 3.0 External right away. It comes with a secondary USB to power cable but that has never actually needed to be used. The USB 3.0 is actually an internal from my laptop in a USB 3.0 case (Put a SSD in lappy ). So long story short USB 3.0 devices should also work but at 2.0 speeds.

I did the same thing with my laptop, but shortly there after, I came to realize that I wasn't using it at all in complete favor of my TF201/700.... Now I've got a lappy with a pretty 120 ssd, and not being used. Coincidentally, I have more space than that in my tablet now...

right so that we have established that external USB hdd's work, what about external dvd drives and other external devices?

I can test it tomorrow, but I would imagine the storage part of it would work. The issues you would run into is not being able to write to it, not being able to play a regular dvd movie as it would have to be mp4 formatted, and other minor issues that require software support.
We already know gamepads, keyboards, mice, flash drives, sd card readers, and other such work..
