Using fast SD cards?

I see these 66x superfast SD memory cards advertised. Will using one speed up my blue angel?
Can programs use this SD card for operating memory or can they only use the intenal memory?
Does having <5mb avaialable slow down your device?

Fast Sd Cards
Fast Sd cards are only useful for SLR Pro cameras. The rest of the devices are using normal card reader slots. i.e. even if you were to use a fast SD card in the sd card slot,you will only get the normal speed.
by rest of the devices, i mean, all pocket pcs, ppc phones, phones and such devices...... :x

moali77 is correct. it won't make much of a difference in your pda. however, if you use a card reader, or happen to have a digicam that can utilize the speed, you will be better off.
example: i played atlantis redux recently 100mb+ required to be put on your sd card. instead of copying it through activesync, i put it in my usb2.0 card reader, copied it over, in far less time than it would've taken if i did it the other way.
but if you don't plan for much of that, then don't bother paying the premium for a fast card =)

Well I bought a Kingston Elite Pro Secure Digital 1GB, think It's 7.7/8.2MB Write/read
It made my TomTom go way faster planning routes and generally give me better performance from other apps.
I dont know the Top speed for the BA SD Slot, but you should look at the speeds of the card you are planning to buy

Have others experienced similar variations with different SDs?

I recently responded to Wamatt's other posting about SD cards in the BA accessories forum. In it, I've described my experiences with the SD card listed in my sig and BA speed tests I've done with it.
See http://forum.xda-developers.com/viewtopic.php?t=26903 for additional information.

Can anyone confirm that the Transcend 4GB 150x SD Card works

Hi,
I was reading a thread on the 4GB SD Cards and am still unsure if the 4GB Transcend 150x SD Card works on the O2 Exec/Universal/Dopod 900? I would like to confirm with someone who has used this SD card in their Exec/Universal.
According to the Transcend Tech Support, they replied... "First of all, thank you for considering Transcend product. O2 series support SD memory up to 2GB.(Please refer to the website for compatibility list)
http://www.transcendusa.com/Support/Search/index.asp .f you have any other question, please feel free to let us know"
I've looked at their site and the stated max size supported is 2GB... This is confusing as other people have mentioned it kindof working..
Would love to know before I jump out and buy it!
Cheers!

RE
There're some discussions here:-
http://forum.xda-developers.com/viewtopic.php?t=37544&highlight=4gb+sd

I bought this card and used for about 2 weeks in my jasjar without any problems. I'm now using/testing in my dopod 818 pro /jamin and again no problems thus far. The size is awesome.

I've used that card in my XDA Exec for a month or so and had no problems whatsoever. The only catch is that the photo camera app won't save photos and videos to it, giving you an error when you try.
Now I've moved it to my Axim. I'm using a 1GB card on my Exec and the photos can be saved to the memory card without problems.

It is so cool,Without any problem.......Work very well with my Qtek9000~~~~

Yes, it works, but on my device, the camera application refuse to store my pictures and movies to it. So in the end, I returned mine and bought a 2GB SD Card which works quite well.

Thanks all for the replies... Just wondering if what everyone said about putting 2GB of stuff on the 4GB card, then leaving less than 2GB free, the the camera app will work is true or not?
Not sure if I should take the risk or should I just get a 2GB card instead... :?

It is OK to take the risk, as long as you research if you can return it and get a refund if all does not go well.

I've been using a TOPRAM 4GB 150x SD Card in my Jasjar for 3 days now. I have not encounted any problems.
4GB is a great size. 16GB would be better.. :lol:

Have you test saving pictures and movies on to this TOP RAM 4GB SD card?? pictures taken from camera application I mean..
If you have done that and no problems arise, then it's the SD card brand issue. which means Transcends SD card don't work as well as Topram don HTC Universal

Yes I just set Camera to save to Storage Card, took a couple of 2MB pictures - saved as 208K, and a short Video.
They were saved in \Storage Card\my documents\My Pictures and in \Storage Card\my documents\My Videos respectively.
Uploaded them to PC via Active$tink, and viewed them. No Problems.
So the TOPRAM 4GB 150x SD Card is OK on my iMate Jasjar.
Any other tests required?
P.S. I bought this on ebay with a free bundled USB 2.0 SD Card Reader that also works with this 4GB SD Card...

How much free space did you have on your 4GB card before you took the photos/video?

About 400MB Free Space at the time. Do you think that has a bearing?

Yes that sound like it has a bearing... According to the discussion on http://forum.xda-developers.com/viewtopic.php?t=37544&highlight=4gb+sd. If you have more than 2GB of free space on your SD Card, then the camera app will not work. I think that you will have the same problem with your 4GB SD Card as others brands 4GB SD Card.

I don't know if this has been said yet, but I think I might know what's causing the trouble.
2GB = 2.048MB = 2.097.152 KB = 2.147.483.648 Bytes
A DWORD (32-bit number, used in loads of windows apps) can handle up to
2^32 = 4.294.967.296, which SHOULD be enough
However, if the number is treated as signed (means it can be positive and negative), one of the bits is used to keep track of the sign, and thus the maximum becomes:
2^31 = 2.147.483.648
If you go over that, the number will be negative.
What I think that's happening is that the camera app calls something to get the free space, gets a DWORD, treats it signed, and thus if you have more than 2GB free, it thinks it's a negative number and will thus not allow you to shoot more pictures
The fix is simple: Get more than 4GB and the sign will probably change to positive again Downside, once have less than 4GB but more than 2GB free it'll show the same symptons
Just kidding
Anyway, as I see it, there might be two fixes:
- An app that keeps a file on your card, and keeps it at a size so that you have just under 2GB free.
- A patch for the camera to either fix the signed-ness, or hook into the API and return 1.99GB if the free size exceeds that.
Unfortunately, I don't have a 4GB Card *yet*, so I can't look into it
I'll see if I can somehow fake a filesystem with more than 2GB free, else you'll have to look at vijay55 or someone else nicely
I might buy a 4GB card, but then again, I might decide not to because of these compatibility issues :/

Might want to read my post just one before yours
I highly doubt it's a problem with Transcend as other apps and the OS itself works perfectly with it, I think it's the fact that it crosses the 2GB boundary of free space and thus the Camera ****s up

How about partioning the SD? If you partioned it to half the size of the the 4GB you would have 2 2GB parts minus the space you always loose on SD cards...
Hmm I saw that was also mentioned here http://forum.xda-developers.com/viewtopic.php?p=214020#214020

Hi All,
Just to let you know. I bought the Transcend 4GB 150x SD Card today for my O2 Exec phone. As expected everything works except the camera app if you store photo/videos to storage card when you have more than 2GB of data free. I have therefore put over 2GB of files on the card leaving only 1.8GB free at the moment and heh presto the camera app works. (as everyone has been saying!).
Well I'm chuffed I have a working 4GB SD Card now!
Only issue is the SD Card access seems to be slow. This seems to be the case for any SD Card I use in my O2 Exec (512MB, 1GB 60x, 4GB 150x). Anyway of speeding things up? Registry hack??? Pocket Mechanic states that it's only 0.16mb/s!
Also another issue was the card is not recognised by my laptops built-in SD Card reader! Luckily I have a external one which worked ok! Anyone know how to solve my SD Card Reader issue? I've emailed Benq tech support hoping they have a new driver or something like that. But no reply yet.

RE
Hi makuk,
Which Pocket Mechanic version are you using on your EXEC? Is it Wm5 compatible?

4GB SD Card

Hello,
I am a new Blue Angel user (bought it used) and so excited to get the best out of it.
Well, I am trying to upgrade the storage, and trying to buy 4GB SD Card...
I have seen a lot of
"Dane Elect 4GB SD Cards" on Ebay and
"Transcend 4GB SD Cards" on Amazon, and
trying to buy either one of them.. but I am wondering,
-Are they both compatible? and..
-Which would be a better choice?
Your replies much appreciated.
Best regards,
J.

4gb card
i have a topram 4gb card 150x and all is working ok on my xda 2s with tomtom 6 and mp3s, movies

4GB
I bought a D-Tec 120x 4GB SD Card, had a bit of doubt as I have never heard of D-Tec.
However, I received it today, and so far it works fine! It recognises as 4GB.

To clarify this a bit more for people -
There are two types of SD cards right now:
SD (1.1)
SDHC (2.0 - HC stands for high capacity). A good primer on the changes can be found here: http://www.sandisk.com/sdhc/SDHC.pdf
Basically, what you need to know - any card that is regular 1.1 (8mb -4GB) will work in the BA. Any card that is 2.0/SDHC (4gb -32gb) will NOT work, as 2.0 is NOT backwards compatible.
The problem here, as you may notice, is that some 4GB cards are teh 1.0 version, and some are the 2.0. If you are not careful, you may buy the wrong card, and end up with something you can't use.
Now, it is possible that some SD devices can only address values smaller than 4.0GB. But, assuming the device is FULLY 1.1 compliant, a 4.0 1.1 card should work just great.
Here is an example of the differences -
This is a 1.1 card:

This is a 2.0 card:

Maximum Size Of a MicroSD (XDA Orbit)

Hello! I called the customer service of O2 today. It says that a storage-card (MicroSD) for the XDA Orbit cannot bei bigger than 512 MB. I cannot believe that but is this correct? Does anybody know the maximum size for a storage card?

Not true - my Orbit runs fine with a 1Gb card, as does my MDAC3.

I am happily running a 2Gb card in my Orbit

Where's the limit?
What about 2GB or 4GB? Will they work with the XDA Orbit?

Hi,
I'm not as experienced as some others on this forum... I'm sure they'll correct my info
I spent a day or so seraching for info before I got my card, and FWI here are my notes:
2GB fine.
4Gb may be problematic.
Thickness of SD card may be a problem. The latch/Phone card has to be correctly clicked into place around the card.
Some makes of card seem better. Sandisk HIGH SPEED seem to be good.
I've got a 2Gb version and it's ok, but read others experiences in the forums.
I got both Lexar and CNex tools to check formatting could be done with full control and also to provide recovery possibility.
Hope that may help.

damned micro sd card
please can someone help?
i have a 1gb sandisk micro card which is being reported by my orbit as 512mb(minus FAT). i put it into my computer and it is clearly 1gb. i have tried putting more onto the card via the orbit, and it says "no more space", but it is fine via the pc. what's going on?!?
thanks in advance,
Tom

Maybe you should try WM5Storage and format SD card on PC. There is detailed instruction how to do it on forum.

afaik there are no 4gb micro sd cards. 2gb is max for them atm

I sell 2gb micro sd for the orbit on a daily basis and had no problems with them, I even use one myself.

not true i have one and its working!

Mobile 2007 .... what make and how I was under the impression 4GB were not compatible?

I'm currently using a 2GB Sandisk microSD card and it is perfectly working.
Regarding 4GB microSD cards, they are called microSDHC (High Capacity) and as far as I know, the Artemis is not able to read from of write to them.

That's what I thought but it appears mobile2007 has got it to work?

I've got a 1gig with all sorts on it. I think 2gig is the biggest at the moment.

When connecting the device via USB cable, don't expect the transfer speeds to be that great. MTP is the default transfer protocol if you didn't change it. If you need to move files off of your MicroSD card quickly, its best to remove the media card from the Note 2 and put it into a card reader. As for the gallery app on the device, from what I have experienced is if you are using the card for the first few times it may take some time for the picture thumb nails to enumerate completely, especially when you have a lot of photos/videos.
This is purely from experience. I hope this helps a bit.
