does (sd-card) speed really matter ? .... - P3600 Accessories

hi all
i'm using pdas for many years now, and always bought high quality over low price. same with sd-cards. if i can get a class6 device for a few euros more i would prefer that. but to come to the question: does it really matter? is a faster card really worth it? is class2 fast enough (regarding the internal sd-card interface of the pda?). i never really saw a big difference in every day use between fast and slow cards. and tools like pocket mechanic NEVER showed speeds close to the theoretical maximum of the card.
so what do you think ...
regards ize|man

Hi
Fast cards worth the money but they must be stable too....
Bye
Jorge

The trick is getting a card that works and is stable in your pda, AND able to read & quickly transfer data with your PC/card reader (need this for transfering movies/mp3s etc). In my opinion the speed is more benificial on the PC side.

my personal experience with sandisk ultra II is that it worked for 2 weeks then got currupted. so i swapped it for sandisk standard & that was 6 months ago, no probs since!

High speed SD card
Sorry for late answer, this is my first post in this forum.
If I can help....
I use everyday Tomtom 6 GPS and I was not very happy of the speed it was working. I tried a 2 Gb high speed (70x) and installed Tomtom in it. What a difference ! The soft was fast and I thought the all PDA too !
Might Helpful for you...

Need to match PDA and memory card ...
I had an issue with any media player misbehaving, and try as I may could not get any music to play without skipping.
Finally I tracked it down to slow memory, namely of the Kingston variety. Having changed the Kingston mini4GB class 4 memory to Sandisk micro8GB class 4 memory all my media player problems seems to have gone away.
I was on the brink of flashing to a WM lite version under mis-belief that it would help. Also I thought of doing some extensive regedits to increase the memory access priority to the card etc. but it seems a more simple solution was at hand.
Match the memory card to the PDA

Yes, I've been using the Sandisk micro8GB class 4 for a few months now. Working brilliantly!

actually, the same for me - i also have the 8 Gb microsdhc class 4 and it works like a charm - much better than previous "fast" minisd from mobymemory.
Still, i am never able to use them correctly under my PC - despite the fact i use a SDHC compliant USB adapter...

Definitely worth the money. I used to use a regular 2G miniSD, lately I replaced it with a Nokia 8G micro SDHC class6 (with mini adapter). Much faster and more stable.

Universal and 8GB SDHC?

Hi all, I just want confirmation that the universal using Beasty & Laurentius 2.08.01 ROM can handle 4GB and 8GB SDHC cards before I go ahead and buy one. I am currently using a 2GB SD card with no problems but obviously would like to have bigger SD(HC in this case), card available.
Thanks and hopefully you guys can let me know.
Works perfect

Internal Read/Write speed is good.
But USB hdd mode terrible slow ( with SDHC cards )
I guess this come from USB 1.1 transfer capacity and speed limitations. ( I've forgot about Read/write buffers, Changing buffer may give damage the device Beasty or Laurentius has said that in a thread. )
Actually USB 1.1 has 42 mbps transfer rate ( SDHC Class 12 cards have 12~48 mbps ) but not in sale at this moment. Currently class 6 in shops ( 6 ~ 24 mbps )
I'm currently using SDHC cards and there is no problem.
Except : Device get small freezings while watching High resolution and high bitrate encoded videos ( 640*480 etc.. )
At the end.
Big storage good for more multimedia.
Note:I've not tried B & L 's latest rom yet . but I Think SDHC driver is same and come from one of Guru of Rom Masters mamaich and I always believe his works.Hopefully it's works for you too..
Thanks for info.
Hi there, thanks a lot for the info, I use my Universal primarily for GPS (I have both TOMTOM and iGo installed) so I just want to be able to put more maps without having to erase any of them when I go back to america. Thanks again for the info, I will be looking into buying an 8GB SDHC card now.

Bluetooth quality?

Just wanted to see what the bluetooth quality/reliablilty is with the Polaris.
I bought a Tytn II from Mobile planet and it was the worst for me with a bluetooth headset, it constantly disconected and was completely unreliable, so much so that I sent it back.
I was also unimpressed with the qualcom CPU finding it quite sluggish and generally slow for any application, especially TomTom6.
Just wanted to see what you guys thought.

I have no issues with bluetooth. It works fine with my headset, laptop, and another cellphone.
The speed of Tomtom navigation is not so much an HTC issue as well as the tranferspeed of MicroSD card. I have a MIO A201 and replaced the 2Gb SD card with a ultraspeed 22,5 MB/sec which improved the performence of Tomtom. Considering that I use now an 8Gb MicroSD Class 4 on thye HTC Cruise (Polaris) means that the transfer speed is only 4 MB/sec and, therefore, has an inpact on the performance of Tomtom.

im sure it has more then 4mb/s.
class 4 means only that 4mb/s is guaranteed, even class 2 crads can reach up to 20mb/s.
Thank you for your response with respect to the transfer speed , can you put a link to the information about transfer speed. I only found that class 4 provides 4MB/sec and class 6 provides 6MB/sec.
there was somewhere a review about various sd cards in this forum, if i find it again ill post it.
With the same card reader I was able to write the same data (2MB) 3 times faster to my ultraspeed 22,5 MB/sec SD card than the MicroSD class 4 card.
I contacted Scandisk who confirmed that the MicroSD class 4 card can reach a maximum transfer speed of 9MB/sec Write and 10MB/sec read, which confirms my statement that it slows down the performance of Tomtom.

The current batch of SanDisk 6 and 8GB Class 4 microSD are very fast card. Despite the "Class 4" category, it is capable of sustained read speed of 20MB/s and write speed of 15MB/s.
You can check the test results here which has 6GB Class 4. Do note that the 8GB Class 4 has similar performance, but NOT 4GB Class 4. The 4GB Class 4 is a much slower card.

And be aware that this speed may not be true for future batches.

Touch Pro corrupting my 16GB and 8GB MicroSDHC Cards... I´m the only one ?

Hello !
Someone got the same problem ?

corrupted my 8GB Sandisk Ultra II after 3 days of use.
The card could be read INSIDE of my Raphael but not on my PC with different card readers. This would be a minor problem but my Raphael also destroyed randomly files on the card too.
I thought the Micro SDHC Card was defective and send it back.
Now I own a Sandisk 16GB Card and it got also courrupted in like 2 days of use.
Some file from my *Notes* was thrashed and other files followed.
Raphael will try to open the file and then stay busy. After like 20 seconds a message containing "There is not enough memory " pop up... (150MB free ram should be enough to open a 2 kb Notes-file )
Wierd thing -> My *old* Sandisk 6 GB MicroSDHC Card I own for more than half a year now works flawlessly... (Till yet )
Someone here got the same experiences ?
Someone got some advice for me ?
I read something about updated SD sdrivers from member Tucan which he cooked into a german stock rom. Are they any good for me ?
Is there a Rom which should solve my problems ?
Help will be really appreciated !!
im sorry but the new memory you have must be fake, that explains why it works with your old mem, and why after sending it back, the same place sent you another fake.
Oh lord here we go, I just ordered my 8gb MicroSDHC card from newegg since the Fuze will be out soon I hope this isn't a common problem.
I corrupted my 8GB once, but by my own fault. I was in the middle of a transfer and was connected as a hard drive, not through activesync, and hit the power button which disconnected it from the computer. I hooked it up as a hard drive again, went into windows and reformatted the MicroSD... No issues from then on.

I ordered both cards from completly different places, so that is unlikely.
They did work normaly (some days) even on my PC, so I guess it is my Raph which corrupted them

I´m always *releasing* my harddrives/cards (on my PC) with the icon in the lower right corner to be save from what you experienced.
Oh man. I have the 16GB Card sitting here and cant use it... I will try it in my old XDA Trion (aka Hermes) for the next days ...
Anyway thanks for your replys !
Someone else has some thoughts about the problem ?
Maybe it has something to do with all the powersaving *features* beeing enabled through -Advanced Config 3.2- and -Diamond Tweak- ?
Well I'm using the same rom as you and was using an 8gb Sandisk card until I got a 16gb Sandisk card and both work flawlessly I'm afraid. I have also applied the power saving tweaks you mention with no ill effect.
using 8gb for about a month now, no problems at all.
Oh, I should mention I've heard many people talk about how there were a lot of Tilts that corrupted MicroSD cards. It was a flaw from the factory, apparently affected a number of them. I wouldn't be surprised of HTC saw some of the same issues with the Fuze, knowing all of the issues they've had already.
My 8gb card works just fine.
For reference, I'm using an A-DATA Class-6 8gb microSD purchased from NewEgg. Cheap, fast, reliable, perfect.
16gb bog standard San Disk Micro SD is working fine at the moment.
Formatted using Panasonic's SD Formatter as I corrupted it before I even put it in the Pro.
my 8GB works fine too
Maybe if everybody posts the brand name of their cards we can determine if this has something to do with the issues.
I remember with my Hermes I had to get a specific brand and produced from a certain plant to not have any issues. I still have my Kingston Micro SD from the Japan plant with no issues.
Using 8Gb and 16Gb of Sandisk with no probs on my Touch Pro.
Hi,
I may be barking up the wrong tree here but are you sure you have not enabled the Encryption setting under Settings. This will encrypt the storage card so it can only be read from the phone. Removing the card and placing in a PC or Laptop would show up as corrupted.
I selected it by mistake once and it corrupted my folder tree and showed garbage.
Not saying this is what is up but is worth looking at.
Personally I have a 16GB SanDisk card in my Touch Pro and it been OK. Been running for about 3 weeks now.
John
maybe the cardreaders from youre PC are not compatible with sdhc.
This is redundand and it may be opinion but im looking into buying a class 6 8gig. Is adata reliable? What company is the best in your opinions for what im looking for. Fastest?

Sandisk. Always. Forever. For my memory cards at least
FYI...
I put a 16Gb Sandisk in my TP on monday (5 days ago)... not a single problem with it and no corrupted files either.
I was previously using my 4Gb Sandisk card from my old Kaiser... which also worked perfectly fine.
Had a Sandisk 8GB card in mine, no problems. Now have a 16GB Sandisk, no problems.
For me I'll buy Sandisk, and only Sandisk, for my memory cards.
I have the very chip you described in my kaiser (class 6 a-data 8gb) runs without a problem. I've never really had much problems with microsd chips but I gotta admit I got a little worries when this thread poped up not so much about the chip but the phone itself, I've never had a bad chip in my life bought about 20 or so thus far, the a-data does well in terms of speed nothing to be excisted about but for it's class and size it holds its own.

Fuze and Micro SD speed class

In searching the forums I know this has come up for other devices and am wondering about the Fuze. What Micro SD speed class can the Fuze use. Don't want to spend extra on a class 4 if it can only take advantage of the class 2 speeds.
Thanks, my Fuze gets delivered late this week, cant wait

I'm running an 8GB class 4, Although I've seen specs that say it supports up to 32GB storage and class6 speeds
I'm rocking a Mobile Ultra 8GB... class 6.
While the fuze (and any phone really) can only take advantage of class 2 speed, your computer can use everything higher. Also, I believe when you're using the direct storage card access mode while plugged into the computer, you can take advantage of the higher speeds as well.

I Noticed a speed tweak in the Blackstone forum for making the SD read time 3X as fast. Is there any way to "port" this setting to the Fuze? I'm beginning to load up on movies and want the best format possible for TV-Out.

I just installed that tweak and, at the very least, everything seems to be able to access the storage card normally. I don't have time to try it out myself right now, but I'll see if I can slap some videos on there for testing later.
I wouldn't let thos Class numbers fool you.. I bought an early 8GB Adata Class4 card and just recently a new 8GB Class6 for a neighbor. Just out of curiosity I plugged each into a mini USB reader and ran hdtach on my PC. My old Class4 card read at 19MB/s and the newer Class6 at only 14MB/s. Explain that...
I have two 8 gb cards, one is class 4 and one is class 6. The difference when connected to a computer is around 10%, but on my Pro I didn't notice any.
However class 4 is almost 2x faster than class 2, and I believe that will have an impact on phone performance.
I could benchmark mine if someone recommends a tool.
I'm running a Sandisk 16 GB Class 2 in my AT&T Fuze,and it runs great!

Depends on the brands and models you got as to what your read speed will be, but the class rating actually has nothing to do with read speed, only write. Also, the class numbers are a guaranteed minimum write speed, so a card labeled class 2 could write faster than class 6 in theory. Here are some read-write benchmarks to show you just how they can vary:
http://www.extremetech.com/article2/0,2845,2094715,00.asp
I haven't found any info on the max theoretical read/write speeds of the flash controller in the Fuze/TouchPro to know what they're supposed to be capable of.
As for the speed tweak from the Blackstone forum...I can't see any difference in playback speed using one Xvid and one Divx video in TCPMP's benchmark. Those are the only two formats I have atm, and they're both technically just MP4 video with MP3 audio.
pocket mechanics can benchmark the sd card in the pda
as benchmarking can't be don on the pc as the speeds will be way different
I think I actually have a copy of pocket mechanic. I was thinking about using SPB Benchmark, but I'll give PM a shot first.
http://pocketnow.com/index.php?a=portal_detail&t=news&id=6415
Article on the cab file and post in the blackstone forum. This article has benchmarks in a graph showing the increase. Anyone benechmarked this tweak on a touchpro yet to see if it works like the HD does?
I have to say that I'm pretty surprised by these results. Both tests were done under identical circumstances and both probably suffer a little due to the fact that I had SOTI Pocket Controller running while I ran the tests. I used the latest version of Pocket Mechanic and an Adata class 4 8gb microsdhc. On the left is the "before."

Yes. Unfortunately, throwing all that extra data at a video processing system that was already choking to death hasn't helped video playback, which is one of the main reasons the patch was developed for the HD. I think I may try to flash the HD derived rom to my Fuze and then retest to see what happens.
If we had the right software to take advantage the hardware we could play DVD,s off this thing
I tryed a full 700meg divx dvd rip that stuttered on play a bit before the cab install, and it plays pretty decent now. It had to be the read time of the phone and not the card that was doing it. Now if coreplayer ever fixs the QVT (blue flicker) on there player it would be a neat toy to plug in with the tv out cable.

Help-Storage card keeps disappearing

My storage card disappears from time to time and now it disappeared permanently, the card is not broken because it still shows up on my laptop.
I read lots of posts here on the forum, but is there a solution somewhere?
thank you !!!

I just enabled the powermanagement again and it showed back up. -.-
This is depressing me because it is the opposite of what I did last time.
Try setting different poll interval. I don't remember how, where and with what... search, you got the keyword
I've got the exact same problem with an mda vario iv, I was posting right now when I saw this. I've already tried setting different pnp delay in registry (as explained here: http://forum.xda-developers.com/showthread.php?t=543879) and didn't change. What's this thing about power management?
I'm also using the Vario IV
well you download advanced config 3.3
here:http://www.touchxperience.com/en/advanced-configuration-tool/downloads.html
and install it on your phone , then after u installed it you need to do a softreset (it will prompt u to). Reboot and launch the program, under power management the first tab is SD card"something", you can switch it on or off.
I saw that when I cant find my card and I switch it on or off (depending how I left it last time) my card returns in my explorer.
Actually I've just changed the 4gb microsdhc card with a 2 gb microsd (non hc) and so far it's working flawlessly... a bit too soon to say it was just a bad card but i'm optimistic. Thank you for the advice about power management, if I'll have problems I'll try that as well
well, I hope it works for you, unfortunately I need that 4 gb, otherwise I havent got enough space to install my navigator in
heh, me too actually, but I hope the problem was only with that ugly 4 gb lexar! I'll go for a kingstone or a sandisk next time!
There have been several post about Class 6 Micro SDHC cards, mainly from Adata and Transcend, not working with Raphaels. I have an 8 Gb Class 6 card from Adata that had the same problem. I switched it with a 6 Gb Kingston Class 4 I had in my camera and it's been working great since last month. I haven't found a fix yet. Raphael's don't seem to like Class 6 cards.
To my knowledge it isn't the card but rather the card slot...I never had a problem with mines until I got a replacement Fuze do to radio failure...now with this replacement when my phone shifts in anyway my card will disappear, then with another shift re-appear. It got to be so annoying that I jus took my card out and place it back in when I need it. I will have to call AT&T to get another or maybe the Tilt II on the 18th
P.S. I have a Sandisc 8GB Class 2

Well, of to the shop I guess -.-
Just gone to the shop for a change, I've taken a sandisk 4gb class 2 this time, and it works like a breeze! Good luck if you're going to change yours too
Well, I went to the shop and bought a sandisk class 2, 8gb card, and its been running like a charm for 5 hours now. Fortunately a buddy of mine still needed a 8 gb card for his samsung and he was gladly to take the class 6 over from me for the same price I paid.
Problem solved.
btw maybe there should be a sticky where it explains that class 6 cards dont work with the Touch Pro.
