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.

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.
I'm thinking of getting a new SDHC card for my Universal (currently running Tomal's v8.2). I'm leaning towards getting an 8Gb MicrosSD card with adapter for convenience, and obviously have the choice of class 2, 4, or 6 - there's not much price difference.
However, OllieD's SD settings ap mentions Type-I and Type-II, and I don't know what this is. I'm assuming it's nothing to do with the SDHC class?
Should I be ok getting a class 6 card, or are there compatibility issues I should be aware of? I'm likely to purchase the card from eBay, so if somebody has bought a MicroSD that works find from there, then please provide the info of type and seller.
Cheers,
Steve.

Hi Steve,
OllieD actually has coded the UI for me. Thanx to him.
Type-1 is actually the driver in compatibility mode of Class4. You should try first the type-2 driver if it's a Class6 card and select type-1 in case type-2 doesn't work well.
regards
Is it safe to assume that those using class 4 cards should select Type-I?
Just to throw a bit of added confusion into the mix; according to SKTools, my 8Gb class 6 Sandisk MicroSDHC runs about 40% quicker using the Type I setting, than it does using Type II.
Cheers,
Steve.
I've just done some benchmarking with PocketMechanic SD-card benchmark and I must say that my Adata microSDHC 8GB "Turbo" class 6 card (in an SD adapter of course) also works significantly faster with "Type I" set. In some cases it's even 2-3 times faster.
Agreed, this is what I have found. Type-I is faster for my 8GB class 6 card.
My 4GB card was about same speed with any setting.
And my 2GB MMC card was fastest with Type-II.
I tested my card: Kingmax 8GB SDHC class 6
It is 3-6x times faster with the Type I setting.
My V-Gen 4GB SDHC is unstable with type II, need to be re-inserted all the times. but, it very stable with type I.

Yeah, I found the same with my 8G SanDisk Ultra-II. I always select Type-1 now and have never had any problems.
Only thing I would add, if you're playing with ROM's and have to DOC-format the device, make sure your SD card is out and safe somewhere before you start resetting the device into bootloader mode.

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.

Hello!
I bought Kingston 16gb class 10 micro sdhc card and I tested it on my nexus one getting result 6mb/s and in unbutu getting same results. Both was directly pluged (Not Usb). I closed every running application in nexus one and I got same result. I also tested in different partitions and in ext2 I was getting little slower result than in fat32. But both were same or under 6mb.
Is there something wrong with the card or is it issue with nexus one that android 2.2 doesnt support class 10?

please include where it was purchased, how much, and if there are any serial numbers/stamps on the card. there are known fakes in circulation (even brick and mortor retailers) fyi.
http://www.verkkokauppa.com/popups/prodinfo.php?id=1244 , bought for 101 euros. Serial in the card: SDC10/16GB N0206-001.AD00lF Taiwan.
ANd on adapter reads CHINA
wow thats really slow i have a 16Gb class 4 and i get 7 ~ 8 mb write speeds when the card is in N1 and connected with usb.
I would assume it's the card because as I and someone else stated above, get higher speeds with a lower class card.
As stated here:
It's my understanding that the "Class" simply refers to speed rating and thus should not effect compatibility. As long as the card supports the microSDHC standard and isn't any larger than 32gb it should work. You should also note however that in the past, vendors have claimed a higher class rating when the card did not actual perform that fast. I suggest buying from a trusted vendor with a good name.

Class 10 should be supported, but they are usually SDHC3.0 card which is new I think...
I have a kingston class 10 as well, same issue, read speed is good but write speed is rated as 2gb, I tried to change the sector size to 4k and still the same.
For those thinking it's a fake card it is not! when I place the card in an adaptor I do 10MB write and close to 16MB read so this is a class 10.
I am not sure if it's the SDC tester app that is wrong or the phone
but since the phone behave fairly well compared to my class 4 card it could be the application. I will do some internal transfer tomorrow to see how fast they go
me too

Hi guys
i recently received my Sandisk Class 4 16gb micro sd card, but im getting pretty slow speeds with it.
Its currently in FAT32 format.
When transferring files from my computer to the card via the usb cable, im getting 3mbps, which is much slower than what ive seen others get with a class 2 sandisk microsd card.
Also when i test the card using 'SD tools' in the app market it says it should have write 5.7, read 10.4, which is not what im getting and still slower than results ive seen others get with class 2 sandisk microsd cards.
I also have an old 2gb Verbatim card (with no class markings), which is currently in FAT format (not FAT32), that came free with an old phone, that seems very quick when transferring files, much quicker, and in SD Tools it gets - write speed 2mbs, read speed 17 mbps.
Questions -
What format should i set the card to maximize performance (not using app2sd)?
Is a smaller capacity card of the same class faster?
(is a class 4 8gb faster than class 4 16 gb?)
Is FAT faster than FAT32?
Is my card defective?
Should i return it for a class 2 as they seem to be faster?
Hope you can help
For starters, which of those 2 file system is really faster don't matter because you cannot use FAT16 on your 16GB card. FAT16 only supports up to 2GB.
Also, class 4 is suppose to be faster than class 2.
sounds like you got a fake Sandisk Class 4 16gb, a knockoff market imitation with low quality component
what is the actual speed test result of the write?

Thanks for the reply allgamer, I've seen many of your posts on these boards and your very helpful
My actual write speeds are 3mbps, when transferring from my pc to the phone via usb cable.
I got the card from play.com so I didn't expect it to be fake. Are there any other tests I could do to confirm its authenticity?
Should I try different file systems like ext2 or fat etc?
3MB/s for a class 2 card is pretty good. I don't what you can expect more from that.
I have an Kingston 16Gb Class 4 and the writing speed from pc -> phone is like 2MB/s, much slower then it should. But in SD Tools its shows 4 or 4.8 MB/s writing speed.

The card I got is a class 4, and being a san disk I expected better write speeds.
What is really confusing is why the 2gb card (with no class markings) I got free with an old phone is much faster at transferring files via usb despite it getting a much lower score in SD tools.
Can anyone explain that?
