I have a QTEK 8500. Would I see enough difference in speed/performance to justify the price difference in a standard 40x speed transflash memory card vs. a 66x high speed card? What (if any) difference would I be able to notice in performance? What memory manufacturers would you reccommend? Thanks! :?:
not sure about micro sd but with normal sd the interface on pda's cant even keep up with the cards so unless there is a world of difference between sd and micro sd then unless you really like to copy stuff to your card from your micro sd card reader no difference

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.
Hi guys,
I'm thinking of upgrading my 512mb SD card to 2gb, but I'm not certain that the phone (Qtek 9090) will be able to work with such a large card.
Does anyone here have a 2gb card working? Any brands/models that are known to work or fail?
Thanks in advance for your help.
2gb SDCard...
Hi!
I'm currently using a 2gb SanDisk SD Card, everything works great. Oddly enough, I cannot find a card reader to connect to my PC that can read them!?!? I'm still using 2003SE and transfer movies and MP3's to the phone by using the painful multi-hour process of Exploring via ActiveSync. Uggh! This is fixed in ActiveSync 4.1 but ONLY if you are running WM5... Just having 2003SE and 4.1 will still be totally laggy for file copy.
Enjoy!

Hi there, I also have a 2Gb Sandisk card in my XDAIIs, I also have a card reader which I purchased from PC World for £10.
Works a treat!!

Hi! Do you have a brand name or model number of the card reader you mentioned so I can search for it on the Internet? So far I've purchased 2 different readers and neither can speak "2gb" :shock: The one I can use for 1gb cards but not 2gb cards is Belkin F5U248 rev.2, so I know that one wont work!
Thanks in advance!
Does anyone know what speed the BA supports for its SD cards?
The transfer speed is limited by the SD card type
The transfer speed should be contained within the card specification sheet
As I understand it, the maximum transfer speed is 22.5MB per second
This is for a 133X SD card, so compare accordingly
thanks for the reply. I just wanted to make sure that there wasnt a limit on the SDIO bus on the BA.
I'm planning to buy a 2gb Sandisk, but i'm not too sure whether the ultra version will work, as the compatibility list on their website only shows the standard. So i might just get the standard one to be on the safe side.
I currently use 4Gb SD card! I had only hard time finding flash card reader for my PC, which can read such a big card
I believe PPC devices has no problem with big SD cards. At least my Mio 168 PPC with GPS (PPC 2003) understand 4G card too.
But I do not believe flash manufacturers X rating. I NEVER seen real speed more than 3 Mb/s on any type of device. My card have rating x133 (22.5Mb/s). And I have no idea on what device and how did they measure that speed?
From the 2g->4gb reports it sounds like sd card size is not so much an issue for the BA, more for the SD->USB adaptor.
I have the same awful USB activesync file transfer rates reported on this thread, despite running WM5, so it sounds like my current adaptor might need upgrading.
Anyway, thanks for helping out, and I now have a 2gb 133x SD on order for next week ;-)
The typical transfer rate is 2MBps
Quotes like 133X and 150X are NOT a multiple of this but the coefficient comparison between the read and write speed
As an example for a 2MB SD card
Uploading 2MB data takes 1 second
Reading data, for that same setup, takes 1 second
For the 133X the write speed is the same, but the read time is 0.4 seconds and for the 150X card it is 0.33 seconds
This also assumes the SD interface meets SDIO v1.01
If not then the 133X and 150X cards take the same time to read as the standard card
2gb Card Reader
Hi there ottGalaen,
My card reader is made by PC Line, I think it's PC World's own brand, the Model number on the back is PCL-CR400.
Here's a link to it...
http://www.pcworld.co.uk/martprd/st...null&sm=null&tm=null&sku=818835&category_oid=
If that doesn't work just go to www.pcworld.co.uk and search for PCL-CR400
I hope this helps
Kind regards
Terry

Yo, what type of SD card that you using now (Sandisk Ultra II) ?
Just so you guys know my 4GB SD card is a Transcend 150x.
I bought this card from Amazon: http://www.amazon.com/Transcend-mic...YX8U/ref=sr_1_5?ie=UTF8&qid=1322469285&sr=8-5
Although I've noticed my write speeds when transferring 700mb-4gb type files only to be 2.32MB/sec. Reviews on amazon show that others are getting 4MB/sec...
no... but i saw this browsing the web... http://www.adorama.com/IDSMICSD32G.html?utm_source=ET&utm_medium=TransactionalEmail&utm_campaign=2point0Product1 its cheaper...and the site has great reviews...
I have the same card and my speed is around 4.2MB s. Have you try testing the speed of your card on a PC?
You can also try to format the card in the PC. I've seen it helped with my other micro sd card for the Motorola Photon.

how should i format it, in FAT32? i formatted it with the phone after i got the card.
i also notice that if i transfer files while in clockwork mod recovery, it'll transfer at 3.5-4MB/sec, but back to only 2.35MB/sec when booted up.
Yeah just format it to fat32. You can also try "sd formatter" program for windows.
Have you tried the Android app "sd card tester" to test the card speed? Do that test first to see if the problem is indeed with the micro sd card.
From my experiences with micro SDHC in the Nook Color, there is no substitute for SanDisk cards. Their class 4 card is faster than everyone else's class 10s.

Just to clarify this fact, as it depends what you use the SD card for.
If you are running an Operating System from the SD card Sandisk have been found to have very fast random read/write speeds, but if you're recording video etc a Class 10 is better. The reason is an OS needs to write and read data from all over the card but recording video writes sequentially.
If you're not running the OS from the card, a higher class of any quality brand card will serve you better. If you are running the OS from the card, like many of us are with our Nook Colors (and lovin it), get a Sandisk Class 4.
How fast is the OG Epic's SD card interface?
I am planning to give Link2SD a try. I will buy another SDXC card for this purpose. I do not want the SD card to be the speed bottleneck. But there is no point spending the extra $$$ on wasted SD card speed. How fast is the actual SD card interface on this phone?
Probably this has been discussed before, but I do not see it in the specs.
Thanks in advance.
I look for the more reliable micro sd card with a good price
https://www.amazon.es/gp/aw/d/B06XFS5657/ref=cm_cr_arp_mb_bdcrb_top?ie=UTF8
https://www.amazon.es/gp/aw/d/B073J...6_SY340_FMwebp_QL65&keywords=sandisk+micro+sd
The best of these in your opinion?
Samsung 256 gb or sandisck 200 gb es wath is more reliable and best choice?
Thanks
I honestly think that you will be happy with either. I have cards from Samsung, Lexar (not sure they are in the SD card business any more) and SanDisk and they are all very reliable. I did have a SanDisk card break once, but I'm pretty sure that was the phone as it ate a couple of cards before I got rid of it. Speed wise you will probably find that the Micro SD cards will be very similar. For some reason full size SD cards perform much better and there is a greater difference in performance, but Micro SD less so.
