sd card + speed questions

Hello xda community,
I am new to the forums and I really love the website
I just have a few questions about the android that I tried looking for but to no avail..
1.) I have the default 1gb microsd card on my g1 - if I upgrade that to 16gb sd card, will I notice any speed difference? Piece of sh1t.
2.) Where are text message data stored? In the SD? If so, how can I transfer it over to another SD card?
3.) Is there an Eclair ROM for g1s?
Thanks so much!

1.) It depends on which 16GB card you get. However, you most likely will see a speed increase. FYI, the best bang for your buck right now in terms of cost and speed is the 8GB Class 6 SanDisk Ultra.
By the way, I have measured the stock 1GB SD card and mine came in slightly slower than a Class 4 (@3.5MB/s) 66x (@9.7 MB/s) SDHC card. YMMV.
So, it is possible that you could actually see a speed decrease with a 16GB class 2 card.

What exactly am I looking for if my goal in mind is to increase my g1's speed?
Read/Write mbyte/sec speed?
The Size? (i.e. 8gb, 16gb)
Thanks

I was thinking about getting this:

Sorry, every instance of the word SDHC actually means microSDHC. I thought that it was obvious, however, I really shouldn't assume. That link you gave is the wrong card. That card will not fit into your phone.
This is the one that I have:

If you really want a 16GB card, either get this:
AData - http://www.newegg.com/Product/Product.aspx?Item=N82E16820211378
or this:
Transcend - http://www.newegg.com/Product/Product.aspx?Item=N82E16820208481
or this: (although I have no experience with this one)
OCZ - http://www.newegg.com/Product/Product.aspx?Item=N82E16820227489

Thanks a lot for your advice. I ended up by an Adata c6 8gb microsd card for $27 at Fry's.

2.) Where are text message data stored? In the SD? If so, how can I transfer it over to another SD card?
I would also like to know
3.) Is there an Eclair ROM for g1s?
Yes, but not everything is working
I am waiting for one where everything works...

Anyone use Sandisk 16gb class 2 card? How is it?

I've just ordered a nook color. I would like to just run roms off of the card. Does anyone have the 16gb SanDisk class 2 card? I speed tested one I already own with crystalDiskMark 2.2. The results were 4.65mb write. 18.62 mb read. The results could be being held back by my terrible usb card reader (vivitar). If the results are accurate, do you think that will be fast enough?

My experience with a Sandisk 16GB Class 2 card is that it works but is actually pretty slow. I have noticable lags on downloads and any activity where sd access is required. In my case, it is slow enough that I have been able to use it to play with froyo, but I would not call it a daily driver booting from this card.

[Q] Micro SD/SDHC card compatibility for the B&N Nook

Hi everyone:
I have been running 6.8 from my Sandisk 2GB unrated card. Although unrated, the card runs relatively fast with the Nook as measured to my Samsung Captivate or Apple iTouch (2nd Gen).
First Card: I backed up the image from my 2GB to a 8GB A-Data Class 6 card. Now this is where the problem starts. The Nookie boots up but down is acting slow and sluggish. To the point it is unuseable with lot's of FCs. I tried buring a brand new image and it is the same. I also tried the card as a data drive max'ing it out to 8GB and also using it to record video in my digicam, no problems.
Second Card: I then bought a Patriot 8GB class 10 card and copied the image onto it. Even worse. It won't even boot or get stuck in the boot process on the "Customted Froyo" screen. Try other images, and the same things occur. The card also works fine as a data card.
Third Card: Third time's the charm. I got this card from Costco. 8GB, class 4. Copied the image from the 2GB to the Sandisk 8GB, expanded the partition like the others. Worked like a charm and runs even smoother.
My question here is:
1) Is the Nook picky about micro SD cards? Seems like the faster cards are having compatibility issues.
2) For people complaining about performance issues running off of the micro SD card. Could it be caused by compatibilty issues I've experienced?
FYI, I've been running "Customized Nookie Froyo" from my micro SD card for about two weeks now with no problems. This will be my daily driver. I get the best of both worlds, Froyo and the B&N image.
Something to think about

Evidently the NC is picky about cards IF you are going to run from them - which is somewhat more intensive than is intended for an ereader additional storage device.
There are existing threads on the subject, just search TITLES for "card" in this Forum only.
Summary - The Transcend 8gb Class 6 seems to be the favorite. Some Class 10 cards don't work correctly in Nook. A-Data makes great Desktop RAM and crap SD cards. Sandisk is a safe choice when on sale, their Class rating is conservative.

Patriot 8GB class 10
I have the same card and works great. Strange. I don't know why you are having so much problem.
Did you try a new IMg? .3?

i tried the following

I tried .3, 6.8, 6.7, and HC all with boot or performance problems. I have two Sandisk8gb cards now and able to run all images with no problem. Typing in HC right now.

Bad batch? I tried hc .1 .2 .3 no problem. I guess I am lucky.

I have class 4,6, & 10 cards in 8Gb, 16Gb, and even 32 Gb. Mix and match of brands from SanDisk, A-data, Wintec..etc. Only issue I've run into is using any of my 32Gb cards, they just plain do not work right. Whether I use them for just storage or even a ROM running from them they are nothing but trouble. One thing I have noticed tho is DO NOT format the card using Windows before burning an image. You are better off using a3rd party app to format the card, it seems to work much better. Or format them with Linux if you have access to it.
BTW as for the 32Gb cards they don't work well with much of anything. And from reports I've seen on the web it seems to be a known issue where all the mfgs say they can use 32Gb cards but they do not have the software bugs worked out seeing as most people don't own or use them seeing as they are a bit pricey still. At least for a decent one they are

Hey quick question will2live what is the class rating and size on the Wintec card you're using?

I have a kingmax class 10 16 gb card....HC and nookie froyo refuse to boot......well nookie does, but in the next boot, hangs up...
only cm7 runs perfect

[Q] Issue with 16GB MSD card

Anyone has the problem with scandisk class 4 16gb msd card in your 2X?
mine is rooted with CM7.1 and before and after i upgrade to 7.1
constantly having problem with the sd card
either is not present when physically in the slot or it cannot be read.
does 2X has any problem of using 16gb msd card?
i usually have to eject and insert back the sd card in order to solve the problem.

I have the same problem (i'm running Miui)
Sometimes the 16 gb sd gets very hot and my phone can only see externalsd/download (not my music and other data)

welcome to the club...

maybe it is the "class"
try class more lower
like "class 2"
...
if I'm wrong tell me.
thanks

actually class 4 8gb card was alright with no problem.. just that 16gb is jinked.. my wife dell streak absolutely has no problem with her 16gb card..

I have 16Gb class 2 borrowed rom N97mini... no problems here...

I use a 32gb class 4 card, currently in Topogigi's v2.0.
My 2x doesnt read the whole card automatically at startup. I can access the media files through music and gallery app, but not via file manager. After reinserting the card though, it does read everything and theres no problem

so we have problem with 16gb class 4 sd card..
havent been able to find a class 2 16gb card to test it out..
so glad that im not alone with the 16gb class 4 issue in our O2X..

CM 7.1 with a Samsung 16GB class 10, working good.

The same card, phone (v2.2.2) and problem
Two days ago I updated it to GB, so we'll see now

i have transcend 16gb class 6, with GR5 and HP RC9 it's fine here. have you guys already trade up for your sd card?

I have transcend class 10 16GB on CM7.1 no problem yet.

I had problem with class 4 card. I think 6 is a minimum, no problem since.

Hello, I use verbatim 16gb ( class 10 ) is very good but price is not good

[Q] max size sd card using cm10.1

Hi
Ok reading over and over and have not seen this one asked.
If I use cm10.1.3 can I use a larger sd card say 64g or can it only still use a 32g? Also what specs of card do I need over my head since I never use sd cards for anything. This is the hd+

You can use any size you want, even 64GB. The best SD to use with the HD+ is a SanDisk class 4.

Hmm, any reason you recommend a class 4 card? I was going to purchase a 64 GB microSDXC class 10 card from Amazon; I don't want to get it if there's some sort of problem though. Please advise; thank you

Yes, there is a reason. Some have reported i/o errors with class 10. But some work ok. But I don't think you can get 64GB in class 4, so you may want to try it. But be warned the 64GB will be mounted as ext_sdcard so is not very useful. All of your apps will use internal storage by default unless you use my swap from my HD/HD+ CWM thread linked in my signature.

You're right, I should have thought to do a quick search for error class 10 and I would have seen a slew of reports. I don't want to risk it so I went ahead and ordered a 32 GB class 4 microSDHC. Thank you again for your advice!

I've been using a Kingston 64GB class10 for almost a year without any issue.
It got it for my original TF101 then moved to the Nook HD+ (formatted it to FAT32 from the start).
I use it mainly for movies, ROMs, TWRP backups.
I actually have many class10, class6 cards from many vendors (many Kingston)... never a problem.

I also use Sandisk 64GB without any problem. I have pics and mp3s in my sd card. No apps.
