33,5 GB of music took 2 hours to transfer through USB cable, that was connected to USB 3.0 connector, to 64 GB SanDisk with 30 MBps speed.
Question: What the hell?!
You can have GB of transfer rate on PC or cable but when the data reach the microSD slot of the Z1, they will stuck at maximum of 40mb/s of transfer rate with an average of 25/30mb/s as it is the maximum what you can get. At this point I will use FTP, very comfortable.
But I don't have even 20 MBps. And that's the problem. It's slow. Veeeeeery sloooooooow.

Remember, much like your body, you're only as fast as your slowest part..
The device is writing to the SD card on your behalf through a software bridge.
Plug the SD card right into your PC if you want it faster.. eliminate the middleman (in this case, the phone)

Hello,
whencopying files - let's say some MP3 albums from PC to Kaiser via USB-Sync connection, it takes ages to complete. I guess it's about ~ 300KByte per Second.
I have a 6GB MicroSD Card Class 3 put in the Kaiser and expected a far better speed.
What is your performance?
If you're that concerned about speed, use the 6 GB card to transfer the files. Copy them from the PC onto the card using the USB reader you should have gotten with the card, then stick the card into your Kaiser.
I'm also wondering why the speed is so slow. The manual indicates that the Kaiser has "USB 2.0 Full-Speed". So why is it so slow? Doesn't support ActiveSync/WMDC USB 2?
Coping large files via Activestink has historically been slow. And on older HTC phones would cause disconnects. Two options is to use a card reader to transfer large files, the other is to use Softick Card Export to convert your phone into a card reader.
I already use Softik Card Export and I really love it. Maybe it is a little bit faster, but it doesn't exceed the USB 1 speed...

I just did a test with my TyTN II and Softik Card Export - not more than 1Mb/s. closer to .7Mb/s actually. I tested the USB cable with my portable USB2 drive and it was 25Mb/s - so the cable is fine.
I've emailed Softick to find out if USB2 is supported, or ever will be.
Will post here when I get a reply.

However, Softick Card Export is MUCH better than ActiveSync.
I'll buy it right now...
Thanks !

Hi,
the Kaiser has USB-speed specified with 480 Mbit, but the speed to put onto it some MP3s via ActiveSync is not much faster than with my Magician (USB1.1) before. If I put in my computer directly the MicroSD card (max 5MB/sec) it is much faster although 5MB/sec << 480 Mbit. So the weak point is not the card. Is there any idea to increase the speed filling my card via direct USB connection ?
Thanks in advance !
Best,
Hugo
Your usb data speed depends on what your com port is set to. if you have alot of usb ports then they share the bandwidth between them. so you may only get 20% of your actuall bandwidth if you have a few other usb devices sharing the bandwidth. you can go to your device manager on your pc and increase the percentage your com port uses of the bandwidth
Thanks for your answer,
and you may be right, if I had a lot of devices conncted to my PC. But I have not. The point is: If I put the microsd into an USB adaptor and connected to the PC, it is quite fast, if I took the Kaiser connecting it ti the same USB, it is slow.
Any other thoughts?
Best,
Hugo

This holds true for all PDA devices connected via USB...not just the Kaiser...activesync may be the bottleneck.
Ok,
if ActiveSync may be the bottleneck, how do you work around this slow copy-process? With CardExpord it is quite faster than with ActiveSync (thanks for the hint), but still far away from the limit :
To copy 58 MB from PC to Magician via CardExport - it needed 94 sec
58 MB from PC to Kaiser via CardExport - 69 sec
58 MB from PC to Kaiser via ActiveSync - 235 sec
58 MB from PC to Card via USB Adaptor - 12 sec = 39 MB/ sec
Anybody any idea to increase the speed of CardExport, there is still much room left ?
Thanks for that discussion!
Best,
Hugo
Most SW connecting to your PDA for file transfer do it through Activesync which as stated before is a bad bottleneck (its sloooow).
You are also using the file handling system of the PDA via this method and any number of background tasks will slow this down.
WM5torage (there is a thread running on here) gets around using Activesync so it may be worthwhile contacting the author to see if this will work for you or wether it could be modified for your purposes.
Hope this helps.
Read the specs carefully. It says "USB 2.0 Full Speed". Don't confuse Full Speed (12 Mbps) with High Speed (480 Mbps). What HTC is doing when they say this is commonly called "deception"!
Has anyone tried ActiveSync over Bluetooth to test whether the Kaiser supports EDR?
Ahhh, abu, you seem to be following me to flame!!
Let's just help people please???
EDR (Enhanced data rate) is fully implemented on this device as was not the case with the TyTn (Hermes) and you will find some of my old threads in there about this very subject that you have placed within this thread ( not whatsoever to do with the first post I may add!!)
OH flippin eck! the wine is taking over.
even usb harddisks max out at about 30MB/sec
and as pda's cant keep up with fast flash cards
it's silly to believe that pda's could keep up with
usb2 speeds

Hey good discussion,
I am a bit disappointed of the advertised 480 Mbit (ok in manual there is mentioned USB 2.0 full speed) but I can only see an advatage of 25% against my old Magician with USB 1.1. and even 12 Mbps (USB 2.0 full speed) should result in douple speed as the measured. I did not expect 480 Mbit, but a bit more speed, than currently offered.
Best,
Hugo
well chicks dig it
well some would be bound to somewhere somehow

Sorry Farsquidge, that my comment about video driver issues was spiced with a pinch of sarcasm. But here I am trying to be purely factual.
EDR is clearly mentioned as supported. I haven't tried this myself yet. But this will probably be slower than ActiveSync over USB as Bluetooth 2.0+EDR is 3 Mbps compared to Full Speed USB at 12 Mbps.

Note that they never advertised "480 Mbit". When they say Full Speed then that means 12 Mbps. That they throw in "USB 2.0" in front of this is IMO not entirely honest.

Yep, it could be taken as misleading.
I have never actually synced with BT as I only have my usb cable at work but I have just tried it and it seems much faster than cable connect. May just bring my charger from now on!
USB speeds are the maximum theoretical badwidth of the hardware, and are much highe than what can actually be achieved... Throw in ActiveSync, and USB speed is virtually meaningless...
Understood,
USB 2.0 was missunderstood as 480 Mbit by several (!) professional journals and websites testing mobiles and PDAs and -reading that- by me. Ok my mistake - next time I will directly come here and look for spec...
What I read in the threads above is:
"Mobile has USB 2.0, but do not expect 480 Mbit as it's only full speed, but don't be silly to believe to get real 12 Mbit as there is a big difference between hardware and spec. You really have to be satisfied, if you get real 6.5 Mbit, which is 25% faster than the USB 1.1 Magician."
In the end I am happy, not to get slower...
Thanks for discussion,
Best

I am upgrading from XDA Exec to the Vario III and I was going to buy a memory card at the same time. Does anybody know which class the SD slot is? I am hoping it is nice and fast and supports the ultr high speed cards.
Thanks
Allan
I have a cheap card that I got with the phone and a more expensive one (Sandisk UltraII)
Personally, with the Kaiser, I can't tell any difference between the two. Not when transferring files to/from my computer and not when using the actual device.
However if I compare the two cards in my cardreader on my computer there is a world of difference. (The UltraII being roughly 6 times as fast as the generic one I got with the phone.)
I don't know if it's just my phone or ROM but to me it doesn't seem as if the Kaiser can actually utilize the extra speed at all.
Of course, the Kaiser having an utterly slow USB connection doesn't really help either so maybe there is a difference when it comes to usage on the actual device. If so I just haven't noticed yet as the only transfer heavy stuff I do if pushing files to and from my computer which (I guess) might be hempered by the USB connection.
I'm using Kingston microSDHC class 4 card and in phone it is just so slow as generic ones, but in USB reader it's fast like hell
hey guys,
ever since i got my tilt, data transfer over USB has been painfully slow. for example, a 900 mb tomtom map took over 2 hours to transfer. I tried taking the SD card out and putting it into my laptop. everything transferred in less than a minute, but as soon as i put the SD card back into my tilt, it turned out it was corrupted. i tried searching for a solution to this issue, but couldn't find anything.
halp
you say ever since you got your tilt does that mean that you had other and faster transfers on other pda's because in my exp thats the case with all wm devices
no, this is my first WM phone, and first PDA ever (i had an i870 before)
activesync is slow period, i use a mediacard reader,i highly recommend a storage card and is SDHC and a compatible card reader for your laptop/desktop,can also find cards on ebay with usb readers instead of card readers so you can just plug the card into the usb stick and away you go
unfortunately that's how the USB plug works on these phones. It's USB 1.1 only.
it's not just a usb1.1 issue as usb1.1 should be able to do 12MB/sec which is far from what happens in reallife
To give you an idea, I just did a quick and dirty test of the different transfer times.
RAR: 41.7 MB
Using Activesync:
- Copy to internal memory => 01:05
- Copy to SD Card => 01:20
Using Card Export:
- Copy to SD Card => 00:51 (mean transfer rate: 850 KB/sec)
Using USB Card Reader =>
- Copy to SD Card => 00:04 (mean transfer rate: 12500 KB/sec)
Conclusion: Always use an external card reader for transfering (large) files.
Tytn II has usb 2. Why the speed is so lame then?
The Kaiser is my first device, so I don't have any other devices to compare to. But in a large degree I have noticed the same for other mobile devices (like cameras, mp3-players,...)
It has to do with some factors:
- What app is used to transfer the data?
Working through Activesync to transfer data clearly works slower. That's because AS works as just another layer controlling the data transfer, thereby slowing the process. When you use Card Export, only the regular explorer.exe process is used for tranferring the data.
- Chipset limitations:
It might be that the Qualcomm chipset has a slow MicroSD and USB controller. Manufacturers also have to choose between better battery life or more speed. Mostly better battery life is chose, thereby bringing down the speed.
My old Dell Axim x50v used to sync calendar/appt within 5 secs. But my tilt takes atleast 1 min everytime to sync calender/appt. It takes that long before the sync icon stops spinning and states connected. Do you guys have the same problem?
btw, transfer speeds for data are the same between the two pdas. its just the sync time.
It is always painfully slow to transfer files with activesync, not just the Kaiser but with all PPCs. As far as sync with outlook that is really poor with WM6 and Activesync 4.5. I think I read somewhere the reason is that activesync runs very in depth checks on changes and date comparisons resultuing in long sync times.
my main problem is not that the tilt is soo slow, but why is my sd card getting corrupted EVERY time i put it in my computer? when i copy a decent size file, all the other files are fine, but that one explodes its size like 10x and takes up 90% of the card. my only option is to format every time
weakest link set the pace
if usb2 is supported then there most be a bottleneck
elsewhere
it imho seem to have been an issue with every pda ever
hi
i boght my Kaiser form a friend about 3 days ago and it has hyperdragon IV (september 2008 release) ROM on it.
my complain about it is that the data transfer between pc and fone is very slow. it takes about 17-20 minutes to copy a 175mb file on the fone's SD HC 4gb card (while the card is in the fone). i connect the fone in ActiveSync mode.
in SETTINGS/CONNECTION/USB TO PC i cannot select the option DISK DRIVE as it says that this option need a memory card in the device and it asks me to insert the card. the card is already there, i have files and programs installed on it. what can i do to speed up my transfers?
thanks in advance.

To be honest 17-20 minutes for 175MB doesn't sound that far out. Transfer speeds will be less than USB 1.1. If its just small files I use ActiveSync, if its anything big (Maps etc) then I use a Micro-SD/USB memory card reader which is much, much faster.
As for your issues with the DISK DRIVE option in the USB connection settings I would post for help in the HyperDragon thread (or search the thread first...)

I agree with Andy, that's a question for that ROM's thread. I'm running a 6.5 rom and have the same problem.
USB1.1 is slow and it's the nature of the beast. If you're going to transfer a lot of files, pull the MicroSD and buzz the files over manually.
With ActiveSync is normal speed ...if you want more speed you can use a version of Softick Card Export and you can transfer with 700-800 KB/s ...and if you want much more speed use a card reader.
i understand what r saying . but i must correct u : on GSMARENA it says that the fone has USB 2.0.
The phone is USB2.0 compliant, meaning it can be used on a USB2.0 host, but that doesn't mean it supports the "hi-speed" mode added by USB2.0. And it indeed doesn't.
I think is something strange with data transfer using USB ...probably antothers missing drivers ...I don't know.
Extract from http://en.wikipedia.org/wiki/Usb :
Code:
USB supports following data rates:
* The Full Speed rate of 12 Mbit/s (1.5 MB/s) is the basic USB data rate defined by USB 1.1. All USB hubs support Full Speed.
* A Low Speed rate of 1.5 Mbit/s (187.5 kB/s) is defined by USB 1.0. It is very similar to full speed operation except that each bit takes 8 times as long to transmit. It is intended primarily to save cost in low-bandwidth Human Interface Devices (HID) such as keyboards, mice, and joysticks.
* A High-Speed (USB 2.0) rate of 480 Mbit/s (60 MB/s) was introduced in 2001. All high-speed devices are capable of falling back to full-speed operation if necessary.
Experimental data rate:
* A SuperSpeed (USB 3.0) rate of 5.0 Gbit/s (625 MB/s). The USB 3.0 specification was released by Intel and its partners in August 2008, according to early reports from CNET news. Products using the 3.0 specification are expected to arrive in 2009 or 2010.
So , using my device in USB mass storage mode I can transfer with 1/2 from the full speed rate of USB 1.1

These days USB 2.0 is pretty much synonymous with Hi Speed but when USB 2.0 first came out it could also mean 'Full Speed' and you had to be careful not to get 'tricked' into a 'Full Speed' (vs. Hi Speed) bit of kit.
This topic has been done to death in several threads, heres one I contributed to slow copying to SD card Note the fact that it's not so much the USB hardware limitations that cause it to be as slow as treacle, it's the huge bottleneck that Microsoft (in)Activesync imposes (hence why copying to a card reader on a USB 1.1 port is still much faster than using Activesync via a USB 2.0 Port). Activesync is really a major weakness with Microsofts Mobile Phone OS Strategy IMO.

Well I just said it above!
USB2.0 includes all 3 speeds, low, full and high. So a device that only uses full speed is included in the standard. Compliance with USB2.0 means that the device will work on an USB2.0 concentrator, that's all. This because at the beginning of USB2.0 you usually had both USB2.0 and USB1.1 ports on computers, and some USB1.1 devices would not work if connected to USB2.0 ports due to stricter timing requirements.
People now assume that USB2.0 = High speed, but as Flying Kiwi said it it's only because it is true in the majority of cases, in the books it's not a requirement.
