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

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
Does it?
Thanx

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 have a new Jasjar and the package came with a 2GB SD card. The supplier tells me it should be a 60x card but in Pocket Machanic the benchmark says it is 4x on read and just 0.2x on write.
This is my one and only SD card so I have no others to compare. Is it possible Pocket Mechanic uses a different measurement method and that program just gives low figures for all SD cards? Or is my card really a slow one?
Can someone with PM give me some benchmark figures for their SD card so I know whether I have a slow card or not.
And should I expect a 2GB card to perform more slowly than say a 1GB card?
On my Exec using a 4GB 150X Transcend card, I'm only getting 0.7MB/s read and 0.2MB/s write (benchmarked by PocketMechanic)
Like in most other PPCs and PPCPEs, the SDIO interface is low speed so no matter how fast your SD card can run, you'll be limited to the speeds of the SDIO interface on your Universal.
Good observation O2. Actually I find it a bit surprising the Universal would have a slower than normal SDIO interface. After all it is just about the most expensive (if not THE most expensive) PDA/phone available. I guess I expected better - er, if that really is the cause of our slow SD card performance.
Happy new year guys. I bought two microsd cards. One is a PQI 2GB microSD card for flashing. Another one is a Ridata 4GB microSDHC card for everyday stuff, with a speed class of 6. I don't know the class of the PQI.
I noticed that when copying files from the pc, or when just copy pasting files within the Hermes, the writing speed is very slow. For both cards, the PQI and Ritek, they're around 400 kB/s to 600 kB/s. I used both WM5torage and activesync and they're both this slow. Even for a class 2 card, such speeds are slow. I RMAed the PQI one due to CRC errors when copying. The Ridata has no errors but is still very slow.
I searched the forums and installed the SD tuneup.cab file, restarted the Hermes and its still the same writing speed, around 400kB/s. I used the microsdhc in a card reader in a pc and it writes at 6 MB/s. What could be wrong, why such a writing speed difference? I have red about posters with writing speeds as much as 9MB/s with their phones in the Hermes accessories forum.
The specs of my phone are:
Cingular 8525 Hermes 100
PDACornerPro.V27
Radio 1.56
HardSPL v7
Ridata 4GB microsdhc class 6
Any suggestions, comments? Thanks.
Mate, join the club... I don't really believe that when connected through activesync you will get very fast speed copying. Its ALWAYS been slow as a stoned snail when copying through the phone. sd card readers move like lightening in comparison.
Don't believe you're gonna find an answer to the slow speed problem.
Cheers...
You mean from the very start till now, the Hermes really writes slowly? But some people on the Hermes accessories forum have write speeds up to 9MB/s. Maybe there is a fix/tweak somewhere I don't know about and still not able to find through searching? Any ideas? Thanks.
I've never found it. Most threads I've read about this issue are lamenting the fact it has such a slow read/write speed when connected through activesync.
I generally backup and transfer files through an sd card reader.
Cheers...
Thanks for the reply. Maybe I'll just use a card reader to save time. But those folks at "What brand SDHC card is everyone using?" thread have speeds up to 9MB/s when writing. Aren't they using the Hermes? Or they're using a card reader?
Probably a card reader. They may also be talking about when transfering files to/from sd card when using the Hermes's own file manager as that is fairly fast. I use a class 6 8Gb card for reading Tomtom maps and there is no lag, had a bit previously with a 2Gb card.
I believe the hangup is in microsoft's active sync program. No0t sure about those using vista's own transfer app.
Cheers...

Actually, Activesync can be fast.
Activesync on an XP machine copying to my Herm100 is quite slow, a card reader is much better, but the same Activesync copied to the latest HTC (don't know the model) slidey keyboard phone's internal memory in comparatively lightening speed.
So is there different configurations or drivers for the USB connections on our phones and/or ROMS ?

As you said

Maybe something in the hardware of the newer phones because if it was software, since the chefs use the ported os of the later devices, we should also be getting better speeds if we had updated the OS. I'm currently using build 21109 and I haven't noticed a speed increases...
Thanks for the replies guys. I think its really the hardware of the Hermes that is slow. I bought a cheap $1 card reader and its very fast compared to the Hermes' own card reader. I used Sisoftware sandra to bench my cards. My RMAed 2GB PQI card writes at around 6.5 MB/s while my Ridata 4GB card writes at around 5.4 MB/s. What a difference a dollar makes
