I just got an idea of running some old games on my TD2, but some of them require reading from CD.. That's ofcourse possible only through SD card as internal memory isn't big enough. But I couldn't find any disc emulator for windows mobile so I got 3 questions:
Is it possible and is there something, that could do the job?
If even it would exist, is 8GB class 4 SD card fast enough to support even slow 4x CD rom reading speed?
What performance hit could emulation cause? Eat whole CPU? Most of the games are for 486(arround 100MHz) and can be run in DOSbox, but that's the next layer of emulation so it may not be even worth of an effort

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 !

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

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
hi all..
just a quick question...
im getting a microSD card 8 gigs, and will be using it only for my kaiser.. now i dont know if i should get a sdhc or a normal card ? whats the differenc on the pda?
thanx

There are some 4 GB microSD that are not microSDHC.
8 GB ones are microSDHC.
I'm using a sandisk 8 GB microSDHC in my Cruise and everything is fine
On you exact question : what is the difference I know that SD is using Fat FS and SDHC Fat32 FS. There might be other differences, but I don't know what they are.
Did you check the wiki? I'm sure this had to have been covered before
microSD and sdhc
"sdhc" is a standard for microsd/minisd and sd for sizes larger than 2GB. Thus all 4GB and 8GB (and 16GB and 32GB) cards will be "sdhc" to work.
Or if you are talking about an adapter that takes a microsd and converts it into a standard SD, you would of course require a sdhc adapter. Whether you need one will depend on you, using activesync to transfer large files is painfully slow so putting the 8GB microsd in an adapter and putting that directly in your laptop/desktop can be much more efficient.
I use softick's card export to mount the kaiser drive directly on my desktop and can easily transfer larger files efficiently.

SDHC - secure digital high capacity
i don't know what's the difference between sd and sdhc (besides capacity), but there is some difference. however, device specification shows what it supports and kaiser supports sdhc
SD officially doesn't support more then 2GB. There are some out of spec 4GB ones, but they don't work in all devices as it's not an official format. To allow for greater capacity the addressing system has been changed in SDHC, along with the default format now being FAT32 instead of FAT16, and the reader/device must support that to be able to access SDHC cards. Some old readers won't read them for example.
So for 8GB you have no choice, 8GB SD cards don't exist.
But SDHC works like a charm in the Kaiser
EDIT: BTW while we're at it... does somebody else have some performance experience with the SanDisk 8GB microSDHC?
It's a class 4 card, so if we believe the specs this should mean 4-6MB/s write speed.
Now the other day I've bought a little Kingston set with a 2GB microSD, micro to mini and micro to SD adapter and tiny keyring USB microSD reader. The idea was to use the USB reader and supplied card as a USB key always on my keyring, while the adapters would be appreciated spares as I always manage to lose them...
The added benefit over a standard USB key being that I can swap the cards with the phone if I need to transfer large files.
So naturally I've put the 8GB card in the reader and started transferring some files to check the performance. Now that's where it becomes odd... I was getting sustained 14-15MB/s writes on the card! I'm not complaining at all of course, but it just seems rather strange nowadays that something exceeds the rated specs that much when everyone is battling for performance!
I've triple-checked with several large files, purposedly unplugged the USB reader right after the copy ended to be sure there wasn't some caching going on, but no, the files were always readable and complete...
Impressive, I've never seen such performance from either a SD card, let alone a card reader that often are slower than the cards... Even my good and fast USB key is slower than this topping at about 11MB/s...
The SDHC speed classes are pretty obscure though, the 4MB/s are supposed to be a minimum under some precise conditions...
Mny PC SD Card readers are not SDHC compatable, so you'll need to mount them via the Kaiser/Tilt/Vario via Active Sync.
Well one compnay here has 3 different 8g microSD cards..
one is 40eur - 8G normal
one is 43eur - 8G ultra II
one is 53eur - 8G sdhc
so still, which one will be faster in the pda?
i have a SD card reader that supports sdhc, so its no problem getting one of them, just want to know if the card sdhc will be slower in the pda couse of the secure stuff?
Normally, the 16GB micro sd card should be in stores this month.
If you have the time and money, I suggest you wait a bit longer and get one of those...
speed of the sd depends on it's class rating:
What is Class Speed Rating?
The SD Association has created and defined 3 speed
classes to help you identify speed and performance
capabilities/minimum requirements of SD/SDHC,
miniSD/miniSDHC, and microSD/microSDHC cards and
the host products. The SD Speed Class Ratings specify
a minimum sustained write speed for
SDHC/miniSDHC/microSDHC cards (Class 2: 2 MB/s;
Class 4: 4 MB/s; Class 6: 6 MB/s*).

You most likely won't be seeing a difference. PDAs are usually not capable of accessing a card at more than a couple MB/s, way less that what cards are capable of.
ok thanx... so cheaper / better
maybe ill wait for those 16g, if the phone will support it...
now im using card for navigation (need 2 gig), for pictures (cca 500megs), for Mp3s (cca 1 giga) guess 8g is more then enoug anyway ....
will get the cheapest, hopefully it will be readable on all sd readers
thanx everyone.

As said before, 8GB SD cards do NOT exist. Even if not noted by the vendor, any 8GB card will be SDHC, and will require a SDHC-compatible reader.
For my Polaris i'm using this one : http://www.amazon.fr/Sandisk-Carte-...2?ie=UTF8&s=electronics&qid=1215248577&sr=8-2
Works good. Transfer rate is not too bad.
I have a question about the built in internal SD memory of the phone.
does anyone know what class the built in SD is? I have an 8gb class 4 inside the phone aswell. I want to know which would be better to record to so i can avoid having video hicups and such.
Not sure, but I'd bet the internal memory is fast enough for video recording. I don't think they would have put memory too slow in the phone to handle it..
Everybody is complaining about the choice of 8GB and 16GB internal memory and lack of external SD support for Nexus 7. Looking at the specs for Nexus 7 and also at tear-down pictures, it is clear that the internal memory is not an SD card. In other words, in the older cheaper tablets, you can replace the 1,2 or 4 GB microSDs with higher memory easily. What kind of memory chip/card is used for the 8/16 GB memory. Has anybody looked into replacing OEM memory with alternate higher memory options?
Best Regards,

The NAND chips are soldered onto the PCB. They are non-replaceable without industrial equipment, and possibly some software patches.
Its not going to happen.
Alternatively, Google USB-OTG. Less convenient, but more realistic.
As Mike mentions, USB OTG is the alternadtive. Unlock the bootloader for your nexus 7 and root it and u can just hook up any usb using a OTG cable. I use the internal memory just for installing apps and i use a 8GB Sandisk USB to store things like pictures, music, movies. Streaming media through USB OTG works great on the Nexus 7. I had no problem streaming a full HD 1080p movie from the USB!

Use this If your rooted. It mounts to a folder in the sdcard directory. which the media scanner will pick up. (takes a while to show up if you have a large library)
https://play.google.com/store/apps/details?id=eu.chainfire.stickmount&hl=en
or this if your not rooted. Your can stream the media or copy it to your internal memory.
