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.

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've just bought a 2gb 120x Moby Memory SD for my MDA Compact...and the it does not recognise it.Upon insertion it says it wants to format the card and says it formatted successfully. However I can not find the card in 'file explorer' or 'memory'. When I look in 'About/Version' it says the expansion slot is in use.
After speaking with Tech Support at Moby (Excellent) - We swapped it out for a 1Gb 80x SD card (their own)...and the same problem.
T-Mobile support is ...chocolate teapot comes to mind!
Out of the box rom: 1.01.00 WWE (21/10/04)
Has anyone got any ideas about this one (greatly appreciated)

I don't know that I can comment on your specific problem, as I have a cheap 1GB SD card that works without issues. Your ROM seems to be really old, however, and you would benefit tremendously by upgrading to the 1.11 or 1.12 versions (1.11 is extremely stable and seems to be a crowd favorite). I don't know if it will resolve your SD issues, but it should at least improve other aspects of the phone. (stability, call quality, bluetooth functionality, and camera quality)
Little Survey...
Okay...i've upgraded my rom to the imate Jam 1.12 from club imate site on my MDA Compact to see if the SD card problem goes away....NO it doesn't. This is really frustrating...and the JAM rom is not as good as the tmobile one with periodic slow downs and already one reset.
Anyway folks, I want to see if I can get some correllation with rom and SD cards. So a mini survey for you all. If you have a T-mobile (originally) MDA compact and use an SD card let me know:
Current ROM Make?
Current ROM Version?
SD Card Make/Model/Capacity?
Any problems with other SD cards?
I will publish a summary for everyone later.
P
sd card
i don't have a tmobile compact,
rather a qtec s100, although I got a TMobile manual in my box..
anyway, i have a 2gb 150x speed ADATA SD Card and I have exactly the same problem. If you browse this forum you will see there is one or two more other topics about the exact same issue.. dont think its anything to do with a specific vendor pda i.e. o2 / tmobile.... but rather a jam thing.
I don't think they currently recognise the latest sd cards, although, i've been told they do recognise the 2gb ultra disk from moby memory retailing at about £133.
So, we can either wait for the ROM upgrade to include the latest stuff, or swap or sell the cards and buy another one.. i'm probably doing the latter to be honest as i just cant wait.
ANyway, if you do find the problem, please let me know.
Regards,
Bushmen

Have SanDisk SD 512mb, 100% fine from day one till now.
They don't seem to recognise the 2gb Moby SD...because that was my initial purchase. Then I downgraded to the 1gb. They are going to send me another 1gb from a different manufacturer. Moby are having a few of these problems cropping up.

Do the cards work fine in a PC card reader?
Does "formatting" on the MDA cause the card to be unreadable on the PC (until you reformat it on the PC)?
If so, these are the exact symptoms found on some early Magicians. If the card works in a PC, then it's a fault on the Jam/MDA, not the card, although the fault does vary by card brand. If you don't get the MDA swapped out, you could end up with it randomly wiping your card. See http://www.expansys.com/forumthread.asp?code=I-MATE_JAM&thread=153
If you don't have a PC card reader to test - get one (make sure it's USB2). Life is not long enough to transfer 2GB by activesync!
Imate Jam
My cards:
Apacer 1gb-no problems
Sandisk Ultra 2gb-no problems
Sandisk 1gb (regular)-no problems
For the moment it looks like if you want a 2gb card that works in your Jam, you'd better get the Sandisk Ultra 2gb.

I can confirm, it works on my HTC Magician too, formated with Fat32 on my PC and pluged into the Magician and have full capacity available! Already filled up with 1.4GB of data (TomTom Maps mostly) Really seems the only 2GB SD card working on the Magician :roll:

1GB Magu SD Card 120x Hi-speed, dint work on MDA Compact.
Works fine on PC Card reader. But shows prompt for "Format" on MDA. When formatted, it does not show in File Explorer, but About Box says explansion slot in use. This card works fine on my Orange SPV (1st model).
I am trying for 512MB 60x speed Toshiba card.
Transcend 4Gig works on Jam - WITH SHIM
The JAM is famous for having innaccurate "travel" in its SD contact mechanical design. SD cards that are not thick enough will give this symptom. The fix is to add a "shim" of plastic or paper to the contact side of the SD card.
I use the sticky part of a PostIt note. Cover the entire card area except the contacts at the bottom. Contact side only. The Transcend 4 gig card is too thin, but adding the trusty PostIt fix now allows me to use this huge ($100) card with no problems. Hope this hack fixes your SD issues too - chuse...
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.
Huib
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

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
Hi there,
my 2GB SD card has just arrived and I am wondering which format is safer/faster with WM5, and which cluster size is recommendable...
Thanks,
Manuel
P.S: I benchmarked the card with Pocket Mechanic (it is an extrememory 133xSpeed) and for reading I get a value of 0.96 M/sec - thats quite slow for a 133x Card, isnt it?
IMHO the larger FAT means seek times are much slower for small file writes. In my personal experience, my old old 128MB Panasonic SD card is much faster for general usage than my 1GB Sandisk Ultra II.
Of course, if you copy movies and music onto the card, the 133x would be faster for sustained transfers...
All that, and I can't really answer your question
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 ?

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
