V635 usb transfer sppeds

Does anyone else find the usb transfer speed of the v635 unbearably slow?

I've tried transferring mp3's to the transflash card both in the mobile
phone tools browser and with the phone in usb bypass mode (where is just
appears as an external usb drive). It always takes 4-5 minutes per song.

I'm intending to get a 512Mb transflash card when they start shipping in
April, but the thought of having to wait an hour to upload tracks 10
disturbs me. I know that I can use the xd adaptor and a card reader but
I wanted to keep removal of the transflash to a minimum (it's described
as semi removable after all).

use bluetooth instead. i`ve found the usb connection to be very unreliable.
a bluetooth dongle can be had on ebay for very little outlay. :-)

I've got a bluetooth dongle but transfer speeds via bluetooth are even
slower! I've not found usb unreliable, just slow to transfer files. USB
1.1 is meant to run at 12MBit/s that equates to 1.5Mbyte/s I don't
expect to achieve the theoretical maximum but 5 minutes for a 4 megabyte
song is only 13kb /second - 1/1000th of the rated speed!

I think the problem may lie with my system and not the phone though, as
another v635 owner on the howard forums says they have no such problem.

Other people have now reported similar problems with the transfer speed,
so it's not just me. Only workaround is to put the transflash in the sd
adaptor and copy files using a separate card reader, annoying as the
cards are so tiny I'm always worried about damaging them. It's the only
(minor) problem I've discovered so far with this phone.

Before I bought my V635 this week, I was worried that this would be a
problem, and that I would have to remove the T-Flash card, place it in
an adapter, and put it in a PC card reader in order to get acceptable
transfer rates.

I received my phone via courier on the afternoon of Tues-6-Dec-2005, and
finally got to give it a good trial last night. I found the same
problem - copying MP3s using Mobile Phone Tools | Mobile Explorer (with
the phone in Data/Fax USB connection mode) was giving me awful transfer
rates -- specifically, it took approximately 22 minutes to transfer a
4.4MB MP3 to the phone -- 26.1 kilobits per second. Awful!

Note: MPT transferred the music to phone internal memory, not T-Flash
memory. MPT | Multimedia Studio and MPT | Mobile Explorer do not seem
to allow transferring to or from the T-Flash memory. It seems more
likely that the internal memory, or internal memory interface is slow,
than that USB is slow, considering what I discovered below.

Fortunately, the howardforums.com link above got me thinking that the
problem may only exist with the Data/Fax mode using the internal memory.
Sure enough, hooking up the phone to my PC in Memory Card USB
connection mode resulted in me being able to drag and drop an MP3 (using
Windows Explorer on the 'removable drive') to the phone (T-Flash 512MB
memory area) in 33.5 seconds for 3.7 MB -- a much better ~900 kilobits
per second.

I could probably do even better with the card adapter, but 30 seconds to
transfer a smallish song is OK for me for now.

My relevant specs for the above investigation: 1.8 GHz Pentium M IBM
ThinkPad with 512 MB RAM, running Windows XP SP2, connecting with a USB
2.0 port (via powered hub) to a SanDisk TransFlash 512 MB flash memory card.

Oops! I forgot to mention one more spec: I used Mobile Phone Tools
3.25b for the aforementioned testing.

I use the same phone. v635i. It came with a 512 transflash card.
Having the same speeds results as you did. However, even 30 seconds
for a 4 meg file is a little slow when trying fill a 512 meg card.
I put it the adaptor, filled 'er up, and that was that. Only took a
few minutes that way.
