Card Reader Bandwidth

HEllo there,
I need to buy a new miniSD card for my P3600.
Therefore, I would like to know the bandwidth of the card reader of P3600, in order to choose wisely the best card for it.
If the badwidth is only 5MB/s, then it's not worthy to buy a card which is 80x...
Another question is: will I loose performance if I decide to go for a 4GB card?...I have this doubt because the bigger the card, bigger the mapping of it ...Therefore, more processing power is necessary...
I think is very usefull information for anybody that needs to buy a card for this device...and for that, all help would be much appreciated
Thank you

Probably you have heard all those SD file corruption stories, haven't you?
Nowadays memory cards are real damn cheap - even if it's 80x. But I guess you would want to find the most "compatible" card instead of finding the card with "just right speed".
It's almost for sure that the life span of your card will far exceed your device. The card can be reused - why not buy a better one, stability issues aside.
4GB cards usually come in the SDHC flavors - which doesn't always work as expected since Trinity only comes with partial SDHC support at best, not to mention the corruption bug.... Again you should worry more about compatibility than it's speed...

the program pocket mechanics let you benchmark and compare with other brands in other phones
with normal sd the pda is the bottleneck suspect the same goes for microSD
but read and write is never at the same speed for flash
and suspect the interface in the pda is able to write as fast as it can read of the card can keep up

I don't remember of asking anything regarding compatibility...
My question was regarding the speed...and it still remains:
-Whats the speed of Trinity card reader bus?
-Will I loose performance with a 4GB card?
I already know about the compatibility issues...but if there's no performance issues with a 4GB card, I can buy one of each brand, and see which one is compatible...if any...
I don't think that my questions are stupid, but if you think so, then keeps the thoughts for yourself please.
Regards,

I don't remember anyone ever said your questions are stupid, but if you think so, then read the whole thread again. Really, that would a disaster if we all follow your logic - anyone who did not reply or did not exactly reply what you ask for would think that your questions are stupid, then basically everyone in this forum would fall into this category.
We are trying to be nice in replying your question, knowing that you are relatively new to the forum, and pointing to you there might be potential problems that you want to avoid when making a purchase decision. At least, I think this is even a more valuable advice for those who want to buy new cards especially for beginners, than just considering alone the speed.

So now, we all know that you are not stupid nor asking stupid questions, then how about if you buy one of each speed, and do a benchmark yourself and then post the results back and share your precious experience with all others? It would be invaluable to your fellow readers especially for those who want to buy a new card.

Answer my question, and who knows, I'll do it
Sorry about my rude answer...but it pisses me off, when a threads starts talking about oranges and finishes up talking about apples....
Any way...it seems like we are always changing roms, searching for the best performance, but at the end, we don't know the speed of the biggest bottleneck in the pda...
It's August...seems like all experts are in holidays

Anyone here that could give additional info?

Best microSD card for hero

Hello, I need to know what's the best speed for a microSD card in order to be able to run smooth a hero rom on a 32B
I understood that Class 6 is the best...is this true ?
I found a class 4 card.....
Should I go for a 4GB class 4 card ?
Regards !

class 6 will always be the fastest out of the three (2,3,6). if you can get a class 6 it will be the best. class 4 is good too, but never get a class 2 for hero, i think it's far to slow if you doing apps2sd and running swap, etc.
class 4 will be a good average to get and very inexpensive.

theres class 2,4 and 6. the higher the class the higher the speed.
I would not suggest to get anything less than a class 6, although if you dont move caches and apps to the SD a class 4 COULD do.
for the difference in price I would go class 6

Hello, I need to know what's the best place to place a question like this ? I'm pretty sure its not under "xda-developers > Sapphire > Sapphire android development"

class 6 is already cheap as chips just get any

I have been through a bunch of SD cards, the best luck I have had is with adata that I got at newegg.com. I am currently using their 16GB class 6 card and it is really fast and I have had zero issues with it. Aside from that I also recommend staying away from Patriot branded SD cards and anything "cheap", they typically use the bare minimum speed of the class to qualify and sacrifice things like quality.
Good Brands:
- aData
- Kingston
- SanDisk
Bad Brands:
- Patriot
- anything without a name or class printed on it

@ronni....i can see that you are hiting for the moderators crew...but ur not there yet...so till then, keep quiet if you don't have anything to say ....
The staff is big enough and with enough experience to handle situations like this
@fallen, i did search the forum...but just the development section because i thought that since is a question which from my point of view is related to the development part (cash,apps2sd,....) this is the right place to search
Maybe i was wrong...
@others: thank you very much, i will buy a class 6 tflash tomorow

thanks bro

I can testify that a class 6 card with Hero is awesome! I bought a Transend 8GB Class 6 card from Newegg.com for under 20 bucks and the performance is amazing! The Hero ROM runs so smooth with this card. I don't think this is the best card you can buy but bang for the buck I would have to say it was well worth it.

[Q] Apps2Sd/Compcache/Swap

Just wondering, once we get these options, will anyone use them?
Coming from a G1, I knew swap and apps2sd were definitely needed.
But seeing as we have 768 MB of RAM, 1.2GB of data.
Since internal memory is faster than micro sd cards, would we use apps2sd?
If anything, could we just use http://forum.xda-developers.com/showthread.php?t=717874 that mod?
Since we have so much RAM, would swap/compcache be necessary ?
Just a few questions, thanks for your replies and thoughts. :]

I don't really see the need for them, this phone is flying.

Bet money we will not even see those coming. Ablsolutely no point with native apps on sd card and that much ram.

Please post questions in Q&A section.

sd card for w7

hey guys, getting some errors on my first rom install i did last night so gonna replace my 2gig micro sd card, the one that came free with the phone.
seen this on ebay, any advice recommendations would be very much appreciated
Joyflash 16GB Micro SD HC Card Class 10
£16.99

i would recommend searching as there is litterally hundreds of posts on this
but whilst im here, i wouldnt bother with that
Here is the truth of the matter,
There is no confirmed cards available on the market (potentially AT&T are selling one branded for it but it costs quite a bit and i dont know anyone thats had one)
Second thing, there is no confirmed working cards on the market ( yes repeating was intentional)
The only confirmed card is one that has been tried in a Device and has been proven to work
You have just as much luck getting a card working than one that doesnt however you can increase your chances of getting one that works by sticking to class 2 or 4
im not going in to the details of why... but that is not to say a class 10 wont work, many people have had them working, but it appears that class 2 and 4 have a higher chance of working.
Brand doesnt mean anything, some folk are saying sandisk are the best, however from my point of view this isnt the case as 2 of my cards that dont work are sandisk, inshort it depends on many things which ultimately brings teh whole thing down to luck!

My 16gig Class 2 Sandisk works fine... OS didn't reject it, I get no errors and I get no chugging when viewing sizable video files off the card (1.8gig rip of avatar for instance)...
This is strange as in the same HD2 with the stock WM 6.5 ROM, the card was slow as hell and even populating views for pictures and videos was hell slow...
I ordered a class 6 via eBay so I can diskcopy to the faster card but I'm know its only for my peace of mind...
A class 4 or 6 should do the job but stick to better brands such as Sandisk or Kingston...

WM was crippled by poor driver support, the HD2 at the time of its launch had an amazing graphics potential but we never had drivers, even the XDA ones were only touching the surface of its potential, WP7 uses that potential hence when graphics and video seem more fluid, its a shame, WM is an amazing OS if it only had some TLC, i believe thats why MS has had to lock down the WP7 OS because carriers / HTC / QC screwed WM and the irony was that MS got the blame for it all
whoops sorry posted in wrong thread, your right back on topic!

Not wanting to go too far off topic, I'll say this...
When using an 8gig no-name card I had no troubles with old WM... It only slowed when using the 16gig Class 2 Sandisk...

its luck, i dont think people understand that, perhaps because we all operate on here in a world full of 1's and 0's.
personally i think it just highlights that companys will put on a shelf anything they like of minor but questionable levels of quality

[Q] 4GB Really?

The Mytouch 4g vs a lot of others phones has a whole 4GB of rom.
After I rooted it and installed Royal Ginger 2.1 on it, I saw I only have a little over 1GB for all my apps. Meaning that the OS takes up 3.6GB(formatted) - 1.2GB(Around) = 2.4GB ....
Is there anyway to get more user space? Some phones only come with 512MB of Rom so how are they able to load so much into 512 when we have 4GB and most of it not usable.
Honestly, I think 1GB is fine, just does not add up for me

I think when you see manufacturers talk rom size it's the amount available to the user. So 512MB after os allocation.

so when mytouch 4g says 4GB it means? 4GB to user?

the 4 gigs are supposed to be for the system and any read only data, or apps that don't like being on the SD Card. Even with a hundred apps, it should still be enough. What you'd really want is a larger SD card, and you'll be living in harmony.

No 4GB total of which 1.1 available.
Desire for 512MB of which 100 or less available to user.
Rest is storage + cache.
Desire canbe changed VIA hboot. If same can be done to glacier, im sûre u'll find the remaining space.
