i'm running this app's card benchmark and the results are a bit dissapointing for me. yesterday i bought one kingston 1gb elite pro (50X) and the tests shown only 4,6X for read (0.68 mb/s) and 1,2X for write (0.18 mb/s)... why?
probably your results are mainly affected (limited) by your devices sdio-slot? i guess the sdio-controller is a lot slower than the cards abilities. have you ever tried to benchmark the card in a card reader connected to your desktop pc? the results there should look much friendlyer to you ;-)
regards
peter
ps: i have sdcard of 2 + 4 gb rated 150x and the results in my htc universal look similar to your results, so don't worry it is normal.
could you tell me a program for pc to run benchmark? actually i do not have a card reader, but a HP photosmart 7260 printer which has card reader on.

Can we use the Sandisk 'Ultra' line? If yes, does anybody know if the faster transfer rate of the Ultra card is supported by the XDA?
try using pocketmecanics it got a benchmark tool
and that seem to show that
the xda2 at least use the pretty slow intel xcale internal sd interface
making the xda1 faster when it comes to sd speed
with mechanics you can compare your result with a list of pda's with different sd cards
non of them ever reach ultra speeds
heck they dont even reach the max speed of normal sd cards
if you compare the speed with the same card in a SD card reader
but that dont mean there is not difference in speed
like Sandisk is the slowest thing ever
I'm using a Panasonic 512MB SD Card and it's supposedly faster (and better) than the SanDisk Ultra.
YMMV
I have a Sandisk Wifi + 256 mb card in my MDA Compact and eventhough the driver and such work flawlessly, the wifi performance is very disappointing. With an internet download benchmark I got about 26KB/s througput. I knew the card wasn't going to be fast before I bought it, but I was expecting to get at least something like 100KB/s.
At first I thought the problem was with the card itself, but when I tested an Sandisk Ultra II 256MB SD Memory card with pocket mechanic I noticed that the throughput to the memory card was also very low (0.26MB/s).
The throughput to the supplied mini SD was even worse (0.10MB/s).
Now I am wondering, is there a general problem with the SD bus interface? Can someone verify these results for me?
Or am I mistaken and should I not expect anything more? I did a full SPB benchmark on the device itself and the numbers were even a little better than to some posted in a review.
TIA!
yeah the jam seems to be slow with cards for some reason?!?!
i got a simpletech 10mb read/write one of the fastest and best cards out and i used to get over 1mb read/write on the xda2 with it but on the jam it gets 0.26mb write and 0.78mb read
with my ultra 60x 1gb it only gets 0.23 read and 0.63 write :\
seems so slow
I get similar speeds to this on my XDA II but the SD Card is much faster in an external USB 2.0 reader/writer.
Even worse, I bought a standard speed SanDisk 512k SD card that is so slow, the XDA II can not write to it at all!
I now only buy Ultra 60x or faster SD cards even though you don't get anything like that in performance in the O2 device itself - just reliablilty.
I use an external SD card reader/writer to load it with MP3s etc. I suffer 20 minute backups with Sprite Backup to SD card daily as I have no choice. (I also back up to 2 PCs as well daily - not much faster).

Hi guys!
I've got 2 512M SD memory card:
- Sandisk UltraII 512MB
- Panasonic High speed 512MB
...and I've got 2 device:
- i-mate Jam (QTEK S100)
- Canon PowerShot SD300 camera
Waht's the difference between the 2 SD?
In your opinion the speed are identical?
Is it better to put the Sandisk into Jam or into the camera?
Hi
I read a long discussion about SD card speeds on this site ages ago.. as i understand it, PPC can only read and write at a FRACTION of a slow/normal SD cards read/write speed, so it really makes no difference.. might as well put the biggest, cheapest card you can in it as anything alse is a waste of a memory card...
My own limited experince with a few sd cards i have (bog standard up to sandisk xtreeme III) shows no difference in speed across the cards.
Lovely caemra you have by the way

Well... I understand that in ppc I can put the slower one but...
Sandisk Ultra II vs Pnasonic highspeed?
What is the faster? (I'll put the faster in my camera!)
Hi, sorry if this is a double post. I did look around but could not find much info.
I'm interested to know how well the new 16GB MicroSD cards work on the Xperia. Anyone using one of these? My main concern is that they all seem to only be class 2 atm. Is this too slow to run apps and my videos stored on it etc?
Should I wait till a class 4 16GB card comes out?
Thanks
Edit: I also noticed that SanDisk has a “Mobile Ultra” memory card range. Only up to 8GB though. Anyone using one of these? Is there a big difference in speeds?
i don't think it matters in a phone.
I ordered the eact same Mobile Ultra card today. Should be here saturday, so I will tell when I get it. But assuming it's Class 6 card, it should be fast. I wouldn't go with Class 2, since it's slow. But as Jabe says, it might not matter on the phone.
So as at now no one's using a 16GB yet?
Give me a week or 2. I'm planning on ordering the Sandisk one.
Sandisk Mobile Ultra is good, and it's what I am using for X1. Since it's class 6, the read/write speed is about 20/16 mb/s, which is much faster than class 2. If you wanna watch video storaged in card, this one is your first choice.

Note that the speed in the end is depending on the host itself. If the host is slow, even if you use class 6 memory card, it's not going to make any difference. Personally I believe the phone itself would be the bottleneck and not the memory card.
I know it's not totally relevant but just for reference, take a look at the link below. As you can see the speed of class 2 and 6 are pretty identical as it's limited by the host. This is even with a dedicated memory card reader. Compare the 2nd and 4th entries from the bottom.

If that's the case, what's the optimal speed supported by X1?
So anyone able to compare the 2 classes

I'm using a 16GB Class 2 at the moment. No probs with apps or music. But I have no videos on the card...
with normal sd cards the pdas were mostly not able to transfer as fast as the sd card supported
as the sd interface in onchip and not that fast
would like to see some tests if the same hold true with newer pda's and class X microSD cards
anyone able to follow this up yet?
I'm using a Sandisk 8gb Class 4 HC. No problems with speed or data read/write (on the phone itself).
Using the phone as a disk drive though (not activesync) is noticeably slower than using a USB adapter, *suggesting* the phone itself is the bottleneck?
I'm using a SanDisk 8GB Class II Card and I had no problems with photos, videos or music so far.
Don't think a Class 4 or 6 is worth the price in a mobile phone.
I got my 16GB Microsdhc today. And everything works. Sad thing is it only shows 15GB.
I find no difference in speed between my 8G class 6 and 16G class 2 (both from Sandisk)

it's 15G probably because of the way how "G" is being calculated. 16,000,000,000 = 16,000,000,000/(1024*1024*1024) = 14.9GB
im using a 8g class 4 card, music, apps and vids work great.
just a quick question, the x1 has a sd card limit of 32g, when a larger card comes out like the 128gb card that sandisk has said will come out, could windows mobile have a update so that it can read it or is limited to the reader hardware inside the x1
I have 2 cards: Sandisk 16GB Class 2 and Kingston 8GB class 4.
I use Sandisk in Xperia, and the speed is more than sufficient. It reaches 12-15 MB/s writing on USB adapter. Reading - it's no problem reaching even more. So it's ok, speed wise.
I don't think you would need more speed in Xperia )
There's no HD video recording option in there )
one can use pocket mechanics to benchmark the sdcard speed
if the results are lower i would suspect it show the bottleneck speed
of the sd interface of the qualcomm cpu in x1
I have a 16gb micro sdhc and some .avi videos lag (highish quality). Specifically, top gear season 12 episodes from finalgear.com. it might be the divx client though, Im using the WM 6 Pro version available on the divx website.
I'm planning to get a microSDhc card for my Jade (HTC Touch 3g).
Can you guys please advice will there is any difference in performance, response time and speed between 4GB microSDhc and 8GB microSDhc.
For the timebeing, I'm using mere 1GB micro SD card and its works great.
I know that both works with Jade, but how about the response time? I'm surely looking for bigger space, but not at the cost of speed and response time.
Thanks!!
HTC (officially) supports only 4Gb SD. Many I know have used 8Gb without problem. Personally I'm using just 4Gb without problem. Response time - blink of an eye, I do not have an empirical engineering measure though. Most of my programs / applications are on SD and the response time are OK.. so far, over a year now, never fail.
I use this one without any problems:
http://www.amazon.de/gp/product/B001D0ROGO/ref=ox_ya_oh_product
I have no exact data for response etc. but it is very fast.
I am using an 8gb, I can't compare it to a 4gb since I don't have one.

Thanks Azahidi for the info!!
Even i'm planning to have my most of the programs/appilcations on the storage card, so was wondering about the response time.
On HTC site, they said they have tested 8GB, but didn't mention about the performance.
http://www.htc.com/in/faqs.aspx?p_id=174&cat=270&id=85794&f=t
But, the salesman at the store said 8GB will make ur device slow, which I didn't want for more space.
So, was looking for the expert opinions on this.

Have you guys installed programs/applications on the Storage card?
And is the reponse of those program on SD are marginally slower as compare to similiar application on device memory?
Even I'm looking to bigger space, it helps a lazy person like me to clean the storage after long long time.
How is the access time for data like music/video/documents from SD and how about the stability?
Thanks in advance!!

I installed nearly all programs on my card (see above) and I have no delay or other problems with it. Of course I do never remove it.
Speed for Cards...
most of the new Cards u can use have different "class" of speed, it give class
Class 2: 2 MByte/s - 13x
Class 4: 4 MByte/s - 26x
Class 6: 6 MByte/s - 40x
i use a Toshiba 8GB with Class4 (i pay 8,-EUR at eBay) and this works fine.
The most of the Programms I use, I installed on the Card except Phoneweaver or eqal Software that use direct access to the Sim.
I use for Videos (MusicClips, TV-Series with Subtitle in srt-format and Documentations) the CoreMobileVideoPlayer and the Videos works fluently perfect.
I have a second Device, a HTC Diamond with internal 4GB and to this it is no different with the speed (memory access).
I hope, this helps a little bit

Thank you so much!!
It is a great information you shared and really helpfull for selecting my Storage card.
well i use an 8GB micro sd card and it works like a charm
besides i heard that our jade can hold up to 16 GB's (thats what the folks at htc store told me) not quite sure about it but i guess the more storage u ride the more battery consumption u get
so i guess its fairly enough to stick with 8Gigs.
HTC touch 3G ( jade 110)
Hi guys. (I own htc touch 3g- jada 110) I am using also 8gb SDHC (kingston) class 4 and I recomend this one. Its fast, cheap (ebay- just be aware of some cheap replicas). I have also tried this card on my girlfriend`s htc tytn 2 (kaiser) and worked as well. So highly recomend KINGSTON cards.
I have both the 4gb and 8 gb Sandisk micro sd card. I can't tell the difference in speed and am very happy with the 8 gb card! Am thinking of upgrading to the 16 gb for my movies though!

Let us know your feedback after using 16GB, if things are stable there..... then we might think of switching to 16GB for the obvious reasons...
