Transfer speed for K750/W800 |

The fastport is not USB2 Highspeed (480mbps), its only USB2 full speed (12mbps) which is why this is a limiting factor.
I never made any comparison between Ipod and W800 and never said you could not make a valid comparison, but simply looked at the device (w800/k750) as a phone with multimedia capabilities, camera/video/music. I dont consider w800 to be a competitor to Ipod, just as the Ipod is not a competitor to w800. The Ipod lacks many capabilities of the w800 (phone, video, camera etc.) W800 is not primarily a music player like Ipod. Its primarily a phone, with alot of other posibilites. From that perspective I dont find the speed of the fast port to be a problem allthough naturally I wouldent complain if it was as fast as an Ipod.
I review these posibilities from a different angle than you. To me its not a question of comparing it to the Ipod, I personally find the comparison silly as the devices are to different. I also have an Ipod, it serves a different purpose and are optimized for that 
Others may have a different angle on this, and I respect that. I do understand and also agree on the points regarding userexperience with software and speed etc. as a directe competitor to the Ipod. Naturally you can make a valid comparison between the Ipod and the W800, if your angle is that the W800 should serve as an Ipod.
I just disagree that these devices are direct/indirect compititors. I find the devices to different no matter how much walkman labeled the w800 is

I just want to point out that USB2 Full-Speed is not the limiting factor.
K750i transfers in 2.5Mbps, not 12Mbps. That's only 20% of Full-Speed.
It's not Low-Speed either, cause that's 1.5Mbps. |

That is absolutely correct. The fastport speed is not the only limiting factor, that was a misinterpretation on my point, but I wanted to point out that the fastport is not USB2 Highspeed.
True, actual transferspeed does not fully utilize the fastport USB2 full speed.
This could be due to settings in windows for hot plugging. Default settings in windows of removable drive in K750 is optimised for safety, so you can remove the device without using the manuel unplug feature. In this setting all read/write caching is turned off both for the device and for windows. You can change it to be optimised for speed under properties, then caching will be turned on, but you will need to use the unplug feature to unplug it safely. I have not made any speedtest under these settings but theoretically this should speed up the transferspeed.
Another limitation could be the devices ability to read/write to the ms duo's theoretical max read/write speed. If so, this could maybe be improved in firmwareupdates unless its due to some kind of hardwarelimitation.

Hi Numb
Fair points, but I'll guess we will ave to agree to disagree on this one
In my view, SE are marketing this as a walkman phone. I feel the comparison to the iPod is warranted because of this. This is different to how the k750 is marketed (primarily an imaging device). I know they are the same, but this is how SE are marketing the products to costumers.
As a walkman, the w800 isn't what it could have been. I have to say the sound is pretty damn good though. However since SE were redesigning the port for the K750 onwards, and making all the older accessories non compatible, more should have been done to "future proof" it. In 2 years, a USB 2 FS link will be a significant limitation, unless we are looking at another redesign (bye bye accessories again).
Personally I feel its a problem now. Maybe next year, on the next models with the same performance, then you'll agree with me

Sigh.... looks like I will have to bring my ipod around still 
Thanks Numb for the clarification on the USB 2 speeds.... |

hehe, yes guess we still have to bring our Ipods
All Ipods and my current needs from the phone aside, I actually do have to agree with you both though. It may fullfill my current needs, but its definately not an optimum sollution, neither in terms of transferspeeds nor in terms of userexperience and software. And youre right that if they want to market the walkman labeled w800 as a musicdevice like the Ipod, they should work on improving these matters. Jason also made another good point about the fastport, it should have been USB2 HS considering we dont want yet another redesign in the near future, and they should have made access to the internal memory use the same speed instead of the silly seriel emulation.
What I really had hoped for (and still hope for in future designs) was a standard mini usb connector on the phone for filetransfers, instead of having to use the same connector for transfers that we use for connecting accessories. Adding this on future designs, could solve the problem with transferspeeds without having to change the design of the accessories connector, and would allow the use of accessories while connected for transfers.

Yup, your suggestion would be ideal numb.
Btw, I just bought a really cheap all-in-one card reader, Singapore $16 = US$10... unknown brand made in China with 1 month warranty heheheh
Speeds really fast now...

Hi numb,
Do you have made some test with such settings?
I could test it if you give me more hints on how to change the settings on windows (was not able to find the good item where to get the properties field :$ )
I find it also really boring to have such a slow speed transfer rate... For a brilliant hanset such as the K750i, it s really annoying 
Thanks for your reply |

well, no increase of the transfer rate
still at 2.5mbps
too bad...
