What's the maximum transfer rate of the MDAII's SD interface?
don't know well..but it is slower than many SD-Cards..
try to check with Benchmark onto PocketMechanic.
So the xdaII can not take advantage of the new fast SD cards? I mean, would it be useless to by a x60 card?
pretty much unless you of cause had a sdcard reader on the pc which could then when you wanted to bring music or what ever to the sdcard for using for the xda2 it would get copy'd faster

Hi all
I have seen that you can get High Speed SD cards does any one know if they work in our XDA II's? and how much faster are they?
read my other reply i'm pretty sure that the xda2 cant even reach the max transferrate of normal non highspeed sd cards
but i suppose it would help if you are transfering files to the sd card with a usb reader there would be a speed inc
Does it?
Thanx
Igb Card Support
Yes I am using a San Disk Igig card for GPS Maps with no problem.
great ! thanx......
...and I use one for movies!
1 gb
i use it for my MP3s and movies as well.
what about high-speed x60 1G SD card ?
faster then normal speed ?
i'm using 1gig 60x pqi sd card. oftentimes it works. problems encountered: xda2 can't detect the sd card. never done the 3x format yet.
you won't see much in terms of speed in PPC. all these fast speed SD is meant for digital camera & video actually.
I have a 1Gig card by 'Integral' that claims to be high speed. I was having some problems running gps mapping etc from it, though for mp3's and videos it was fine.
I have now bought a 512 SanDisk Ultra 2 card and Tom Tom is much better with this card. Using a multiple file read/write test to copy from the card to itself, the new Sandisk card is significantly quicker, and Tom Tom runs/opens much better than it did with the 1Gig card. So higher speed cards do show an improvement, though not as much as when they are in a device that can take full advantage of the card, like a PC card reader for instance.
I have a x66 PQI 1Gb SD card that I run TomTom3, MP3's and store presentations on. I have had no problems with this card at all. The higher speed of the card does make difference and improves the performance to both the applications and the speed at which data is copied to the card (not using hotsync).
Ive found that some really cheap SD cards have loads of problems.
I bought a cheap card and it was terrible, kept not working, corrupting files etc. I swapped for a 1gig Sandisk, all is well, no problems at all.
I found that the 32meg NOKIA cards given with most new nokia phones a year or so ago dont work. They are totally unreliable.
You get what you pay for, the faster cards are normally more expensive, and ive noticed the difference when copying big files from ram to card.
Get the better cards, its worth it in the long run.
I havent looked too deeply into this, preferring to ask like .. So please don't eat me.
Its late and all ..
I'm wondering what speed the SD card reader in the Universal is?
Is it worth spending a little extra on some 60x Corsair SD cards or should I just get the bargain bin stuff since the Universal maybe doesnt have a particularly quick card reader?
Any advice welcome. I plan to use this is a system disk with seperate 512 card for my MP3's and pod casts/documents. THAT will be cheap stuff.
But for the main I need a 1gb system disk for storing apps and system stuff.
Compared to a dedicated USB card reader for the PC, the Universal is extremely slow - I have tested this with my 150X 2GB SD card. So unless you plan on using it with a PC card reader, it doesn't really matter
Accessing the SD card through activesync was at least 10 times slower than the card reader...
I did a small test with Pocket Mechanic.
1. My "normal" 2 GB sandisk gives 0.84MB/sec
2. My super duper Extreme III Sandisk 1 GB gives me a whopping 0.88MB sec.
Nr . 2 card, in my portable, writes files much, much faster than nr.1.
You can see however that in my Jasjar the difference is nearly zero.
I would say: go for the cheapest, but I am not a great technician.

Thanks guys ..
Very informative and will help me get the right card. ie. the cheapest!

Hi
I have not noticed any difference between a basic Sandisk card and a so called 66x KingMax card when used in the exec.
I do notice a difference between these two cards when using them with my digicam - the multishot mode (2 frames/sec) actually works cause the camera is able to write to the card quickly enough. With the slow card, cam kept pausing to write its cache onto the card.
I am not sure that pocket mechanic tells the truth! Likewise, timing a copy from the internal flash to an SD card is not gonna give accurate results (speed of internal flash may be bottleneck). On Wm2003 devices this was possible cause RAM is loads faster than flash still.
You cant test the speed of the SD reader in the exec over activesync tho!! Its a USB 1.1 device (max 11Mbit) and on top of that activesync treats it as a 10Mbit network card. Max you'll see after overheads is thus around 1MByte/sec

Certainly much better to do it that way.

ok i m having problem to decide as well...
anyone has a more concrete data about this ?
i m thinking whether to choose a normal 66x or 133x ...
getting 2gb sd card.. either transcend or pretec...
by the way exec sd slot is 1.01 or 1.1 specification?
hope someone has a benchmark to share.. thanks
1gb Scandisk does the job for me.
Watched a movie on it the other night, perfect. Plenty fast enough.
Its HTC so you can be assured it will be genius design with cheap crap chipset.
Bit like an Italian sportscar.
get one of those sd-usb card combo's....if u can find one going at a decent price.
saves the hassle of card readers. the LAST thing anyone needs is yet another wire lol
I've noticed that copying files to the phone (to storage card) via USB cable is painfully slow (as compared to say regular USB stick).
Would purchasing a high speed MicroSD (e.g. Sandisk Premier) help or is the phone itself the bottleneck?
Thanks!
Try connecting your phone as a mass storage device, if you haven't done that already.
You can select this when you plug in the usb cable.
Accessing the storage card is way faster then.

I have purchased SanDisk Mobile Ultra (Class 6) and the performance increase in real terms is marginal!

It would certainly help. Also search this forum for tnyynt's SD Tuneup cab. Note that installing that cab only makes much of a difference once you got a faster SD.
The transfer speed of the SD is limited for whatever reason, power preservation, whatever, it's limited to optimize for slower SD cards. So The SDTuneup cab ups this limit, meaning you will notice a much bigger speed difference when using faster SD cards.
i also find the msd card speed poor. especially when you open up a folder with a lot of images every image software takes minutes to scan the folder.
that is very lame
I'm using the:
MDJs_CyanogenMod7_v.2.3_NAND_A2SD+
And a 8gig class-4 SD
When transferring files of 1-2gig the transfer rate drops to
around 800Kb/sec. So a 1 gig file takes up to 20min.
On the stock WinMo 6.5 it goes 5 times faster.
What can i do to speed this up?
1) Does a different android rom help?
2) Revert back to Android SD instead of NAND?
3) Can i do something on the PC to speed things up?
transfers significantly faster with mac
I have noticed that Mac computers transfer files to the external sd card on Andriod phones significantly faster.
1GB transfer on Windows machine takes about 30 min and the same transfer with a Mac is about 5 min. Both are with the external SD card mounted as a drive. The SD card is a class 10 32 GB. The phone is a Samsung S2.
What gives? Does anyone have an idea why this is happening?
Does anyone have a suggestion on what I can do to speed up the Windows transfers?
Yea, i noticed, with my phone at least, that file transfers usually go a lot slower when Smaller files are being transferred as oppressed to big ones.
In my card reader, it would go about 800k for a large group of 10kb and shoot up to 8-9mb. On my phone, the fastest i remembered it going was about 6-8mb/s. Try reformatting changing allocation unit size to 32k. The only problem is that it will waste like 20mb (guessing) by the time its filed up. Its feels it bit faster but i don't really notice most of the time.
If you do it, don't forget to back up!
