Maximum GB that works smoothly in Elf..

Hey guys, I tried to search about this topic in the forum but I don'y anything about it or was it just already in pit of the forum?
Anyways, I would like to ask the maximum capacity of memory card for Elf(in)? I am planning to buy a micro-sd and I just want to buy the best available.
Does it support SDHC memory cards? And also, does using a large GB of memory presents a risk on my device to be brick when time goes on?
Thanks for the help guys!

I have 4gb micro sdhc and it works fine. I have heard that 8GB won't function properly after a while. But I am not a genius

SanDisk 8GB
I've been working with a SanDisk 8GB MicroSD HC for about 4 months now, and still have had no issues...
And that goes without saying that I think It's a fake SanDisk, because of the packaging.

Have an 8GB SanDisk on my Elfin. Works great.

@vette95: Good to hear that! Thanks for responding..
@htedum: how long have you bean using your 8gb micro-sd? Haven't experienced any problem yet? Any slow down or hangs?

i've been using 8gb in my elf for over a year and did not ever have any issues or hangs so i would recommend it.
just my 2 cents

Wow! Thanks bro for the feedback! Will buy 8gb now.. hehe..

Been using it for two weeks now; no problems at all. I've overclocked to 273 using HomeScreen, maybe that helps. Loaded up 6G worth of music and 1G worth of movies. Installed PocketPlayer (and TCPMP for movies), and I have a slick, portable media player. Battery life isn't bad at all, but I've ordered a 2500mAh replacement, waiting for that to come in.
A tip - be sure to pick up an original, name-brand card, even if you have to pay more. A lot of fakes going around, they may slow down your phone.
@vette95: No problems with your fake?

I've been searching google how to detect fake micro-sd but unfortunately the only info I got was to make sure the serial of the memory is readable and also try to call on the manufacturer and confirm the serial. Of course, I cannot do that when I am in the store, to check each items and call them. LOL. So do you know other ways how to know it if it is genuine?

The best bet would be to avoid ebay and the like; that's where most of them are floating around. Since you're buying retail, you should be pretty safe, since you can go right back to the store if you discover that it's fake.
From what I've read, there's also the issue of classes; best pick up class 6 or at least class 4. Class 2 will be slow.

Also check the packaging. Check if the fonts are printed alright and not fading or anything.

I have already bought a 4gb sdhc class 6 kingston micro-sd. There is no 8gb available in store so I decided to just go with 4gb and just upgrade when I need it. It was fast and I guest it is not fake(though I'm not sure). Thanks for the advice guys. I hope this will also be helpful for people who are planning to upgrade memory.
As far as I know, Transcend and Sandisk are the brands that are flooding in the market which are fake so I really looked for other brand. Fortunately I found one and it is made in Japan(the fakes are made in China written at the back of this brands) so I'm little confident with the memory I bought. hehe..

ive been using an 8gb card too for awhile now on my elfin. just got my 16gb card last month and havent had a problem yet. everything runs very smoothly.

i have 8GB V-gen and running well until now...

8gb
i´ve used a 8gb sdhc since a month without problems...it runs smoothly...

I bought a 16 gb sandisk sdhc. It didn't even register regardless of what drivers I installed on my phone.

Sandisk HC 16 gig Micro SD:

Recently bought one off of eBay for $40 (+ $9 3-day USPS shipping) and it works as good as gold in my HTC Touch Pro. It was listed as "bulk" and did not come in the official Sandisk blister pack; therefore, this could possibly be gray-market hardware, but it works as listed none the less.
Perfect amount of space for my GPS software and my music/talk-radio.
I have had it for about 5 days now and have had zero compatibility or usage issues.
Cheers!

Haha, he said possibly... I'm pretty sure that MicroSD card you just bought was not manufactured by Sandisk. Good to hear that it's working okay though.

Ya, well I bought a 16GB MicroSD card and it has been working FLAWLESSLY...until tonight. I was re-installing a ROM and re-installing TT7...when the install hung...told me it couldn't install...then the card just died. Hopefully SanDisk will RMA it...

Well, most suggest that you remove the SD card prior to installation of a new ROM. I am using my card with Elite RC2 Rom, but have not tried leaving it in while installing a new ROM.
At this point, I have purchased 3 Sandisk Micro SD cards (2 4 gig HC's, and 1 8 gig HC) over the past 1.5-2 years off of eBay and haven't had a single one of them fail... none of them came in Sandisk blister packs.
Time will tell...

Did you try and reformat it? It might just be a bad sector.

can someone find me a good deal on a 16 gb they are all like around 55.00

Im sure you could find one cheaper, but I am willing to bet is bootleg. Anyway the 55.00 ballpark is not that bad. Or you can wait till the 32gb releases. That will drop the price of the 16 big time.

So is the SanDisk 16GB Class 2 card good? Mainly the class 2 part. Will it be much slower than my current class 4 8GB card?

I just got my Sandisk 16gb card. It was Sandisk branded in a Sandisk blister pack. It works, but so far I'm having intermittent problems with my MP3 files pausing and starting again. Sometimes worse than others. It happens with Kinoma, Coreplayer, Windows Media Player and the Sprint Music player. Are there any ways of minimizing this?

It will not be much slower (could even be faster). Check this thread, where someone posted his c4 8GB card benchmark, which was lower than my numbers posted at the end.

Try reformatting, and apply this patch as well. I got a bulk package from ebay, and I haven't had a single problem so far (more than 2 weeks).

Thanks so much! It seems to be performing much better. I will have to test it more over the next few days........

I just ordered and received this one:
http://www.amazon.com/gp/product/B001L1H0SC
It seems quite fine

What is the largest capacity the HTC Touch Pro can handle? I thought it was only a 8GB?

Anyone tryed 32 Gb SDHC?

i want buy 16gb memory but may be 32gb have unofficial support.......

You may be better off getting a 16GB card as the 32GB cards are extremely rare and extremely expensive.

It's a supported format if it's SDHC so it should work. I'd still go with the 16GB because it's the safer option and you don't need 32GB of space on a phone.

Lol... Well yeah, it's possible to fill any amount of space. Having said that, I'd say anything that isn't used on a fortnightly basis is superfulous and as such, I doubt you've got 16GB of 'vital' data?
On another note... the more data on the storage card the slower the indexing and performance. So, I'd weigh up 'needs' rather than 'wants'. Hell, I'd love a 32Gb SDHC crad for my phone, but I wouldn't need the space and so couldn't justify the expense or the reduced performance or risk incompatability.
Still, good point
crabby

very well, but can anyone JUST TRY to check compartibility ?

Well i use my X1a as my music player in my car, so my 16gb is filled up, 32gb would be super nice since i have tons of music i still wanna put on my X1, and a couple of movies i may add!!

Is there such a thing as a 32gb micro sd card? I've never seen it.
Does anyone has a link to where I can get one?

I'm using my 16gb, very satisfied with how much room there is!

A 32GB card ought to work, in my opinion.

I wonder what will be the benchmark for the 32Gb? will it be slower that the 16Gb.. for example for the Class 4... is the 16Gb slower that the 4Gb stock microSD of X1?

the x1 does support cards up to 32gb.
or aleast thats what sony said

32GB Micro SD cards cannot be purchased yet.
The link at the beginning of this thread pointed to SD cards, not micro SD.
As the Micro SD slots are so small, I thought it'd be nice to have two in a phone so you can easily add capacity. Mind you, I've still got an 8gb and it's got a wee bittie of room left on it

Ordered my Focus!!! - Micro SDHC Question

I ordered the Samsung Focus with Amazon Wireless for one penny and a two year contract with AT&T! Couldn't be any happier with that.
Anyway, I ordered a case:
http://www.amazon.com/gp/product/B00495YF8A/ref=oss_product
And a screen protector (I know it's tough to scratch but eh, why not. Lol)
http://www.amazon.com/gp/product/B003F8C1GK/ref=oss_product
So I've been thinking about how much memory is on the phone. 8GB is nice but I will want to put a few of my 720P movies onto the Focus. I figured I could get 8B Micro SDHC (Class 10) and it would make it, 16GB. That's pretty decent, right? I think it will hold me over... Lol.
I did some research and I get the higher the class, the higher the write speeds. Right?
Well, what do ya'll think of this one?

Thanks in advance everyone!!!

8gb is good enough for me....for now! Ill be buying a 16gb card soon enough tho because everytime you change the sd card you have to do a full reset on your phone, so id rather just do it now and get it all over with. So, what im trying to tell you is just get yourself a 16gb card if you going to be adding 720p movies...that way you wont really need to worry about changing the card later. As for the class...class 10 is unnecessary....class 2 has been proven to be VERY sufficient in the focus...even class 4. I had a class 6 and now I have a class 2 and there is NO difference in performance on my focus. Anyways, as for sd cards, be careful because some aren't working properly....I would say your safest bet is buying Sandisk...since thats what Samsung is using in the focus for memory right now.
Hope this helps!

Well, if I put a 720P movie on there, I'll just delete it once I'm finished watching it. Not going to have more than a few gigs of music too. So 8GB is good for me. Obviously once you put a movie on there you can delete it and get your memory back, correct? Sounds nooby but just double checkin... Lol. The higher the class the faster it gets on the card, right?

i got a sandisk 16g class 4 from radio shack cost about $34, had it in since two weeks before christmas.... loaded it almost full, empted most of it out loaded and unloaded stuff, havn't had any problems so far....... been running strong and just as fast as without the card...

correct...once you delete things you get your space back. I didn't notice much difference in transfer speed between my class 6 and class 2. So if you can, just save yourself the money and get class 4. There was an article I read somewhere that a higher class can actually make performance worse on the phone. Don't know how true it is, but class 2 has been perfect for me. No difference anywhere.

You need too spend some time reading this thread before buying a microsd card:

Determining whether an SD card is Windows Phone 7 compliant is not a simple matter of judging its speed class. Several other factors, such as the number of random read/write operations per second, play a role in determining how well an SD card performs with Windows Phone 7 devices.

A higher speed class can actually work against you because sometimes the maker sacrifices random operations for speed.
You can either wait for official "windows phone 7 certified" cards or take your chances. Read the first post carefully, especially the most recent posts. I personally have been using a 16gb Samsung card with no problems. Caveat emptor.

Sweet, thanks for the info.

If you read the feedback, nothing but positive reviews.
"Pros: Very good price to performance ratio. Works with the Samsung Focus. Good read write speeds.
Cons: None
Other Thoughts: Not sure why some say negatives about the speed of the card. Maybe they got a bad one, but this tested out at just under 4.5gb write speeds. I had been using a Sandisk class 2 card with my Samsung Focus, but it would do some random rebooting and crashing. With this card it has been absoulutly perfect for over a week of use. I have 15gb of music and photos on the phone so I know that I am using the memory card along with the 8gb that is onboard with the phone."
Kinda sold on this... Should I do it?!?!?!?! Buy it right now?!?!! lol

This is pretty much what I was asking in another thread. I want to go with a 32GB card as I don't want to go through hard reset if I ever need more memory later on.
What is a good 32GB tmicroSD card hat works with Focus with no issues? I would like name of manufacturer, class and even the part# so I can source locally (go to store or order online).
Thanks.

No lie, you're going to spend a lot of $ and 32GB is overkill.

After reading the large thread on compatible cards above, it seems the real test is if you've loaded over 8GB of data onto the SDHC card (or over 16GB total in your case) and don't experience any problems. If that's the case then that's awesome (and it also sadly verifies the fact that no one knows which brand of card really works than the Sandisk 8GB Class 2, which is mentioned in the official instruction manual).
To the OP, I've stuck with the 8GB Sandisk. I considered the OEM version for $12 USD available on Amazon but decided against it, and went with the retail packaged version, which I got at Radio Shack for $20 USD. 14 or so GB will be good enough until the official certified ones are announced.

well ill just refer to him as mr arse... but mr arse is partially correct.... mine was stable up to 15gb then after that it went downhill fast.... so give the dude a bit of a break....

Has anyone seen any OFFICIAL announcement that there will be APPROVED cards for WP7. I know that Sandisk tried to pull a fast one and say their's were approved but then pulled them. Is MS even allowing such a program?

[Q] Bad Luck With SanDisk Class4 32GB?

Has anyone had any issues running CM7 on a SanDisk Class4 microSD?
I bought one used, and got CM7 running, but with plenty of Force Close errors. After running a benchmark on the card, it sounds like I got a bad card (for running CM7, anyways).
Here are my CrystalDiskMark scores, run with the same card, in various adapters on my laptop:
SanDisk 32GB Class4
Random Write 4KB (QD=32)
Kingston USB Card Reader
0.230 MB/s [ 56.3 IOPS]
Patriot microSD Card Adapter in SD Card Slot ThinkPad L412
0.054 MB/s [ 13.2 IOPS]
SimpleTech microSD Card Adapter in SD Card Slot ThinkPad L412
0.065 MB/s [ 15.9 IOPS]
Kinda crappy compared to other results I've seen. Anyone else have bad luck? Any suggestions, other than a new card?
Thanks!

You'll always get lower scores when testing in a card adapter compared to a USB reader - but the speed you get from the reader seems a bit below normal by about half - you might've just gotten a bad card.
Is it a recent purchase? You can probably exchange it - they run off a ton of these at a time and a bad one's bound to slip through here and there.
The links to the memory card threads are in my sig if you wanna jump back into them quickly.

Where did you buy the card from? Hopefully it is defective and returnable, rather than counterfeit.

This is my suspicion.. However, C4 I'd think he bought in a Brick and Mortar vs online where it's entirely too easy to wind up with counterfeit SD cards.

Bought it from a guy on craigslist. The card seems legit, full 32GB capacity, 6MB/s seq. write speed, just crappy random write speed.
Anyone else with a SanDisk 32GB Class4 care to post CrystalDiskMark Results? I haven't found any when searching the forums... just 8GB and 16GB...

I bought a sandisk 32gb class4 from amazon. I don't recall the benchmark numbers off the top of my head, so I'll have to test it when I get home from work.
I did, however, recently move over from booting off the sdcard to booting off the emmc... It seemed to be a HUGE difference in performance. While I didn't get any FC's when running on the sdcard, the system did feel a bit laggy. Or I could just be imagining things...

Interesting. I look forward to seeing your benchmark results. Was your a standard SanDisk card, or one of those "EXTREME" cards? (do they make those in a class4?)
I've read that a lot of people like running CM7 directly from the onboard memory. I'm weary of doing that, and I also like having the standard nook software too. Maybe if there was a way to dual-boot from the eMMC, then maybe I'd try it.
Thanks in advance for your benchmark test results.

I have two different SanDisk 32gb cards and both have been working fine for me. I can't remember the benchmarks right now but I do remember them being similar but a little better than may 16 gb and 8 gb SanDisk class 4 cards.
It also didn't seem sluggish to me after overclocking it a little bit.

If you have a good card then CM7 runs fine from it and I've done quite a few onto 32G Sandisk class 4 and got nice performance. However, there are significant advantages in running from emmc. For example, you then use the SD card as a simple, single partition card containing just user / data files rather than as a multi-partition card containing both the ROM partitions and user data. Updates become easier to manage as the standard ROM Manager / clockwork methods just work as intended rather than having to put renamed update zips onto the boot partition of the SD.
I'd not be weary of it, just because it sounds like a risky one way trip. There are good ways of reverting to stock if you need to.
It is possible to dual boot Nook stock and CM7 off the emmc, and I did that successfully for a while. The key is in creating extra partitions and moving the Nook software to the new partitions. Various guides are available, e.g.
http://forum.xda-developers.com/showthread.php?t=1275859
I eventually simplified my family installs down to just cm7 as we ended up never using the stock Nook. One can use the Android Nook app for basic B&N content but if you use for magazine or childrens books then that is a good reason for maintaining a stock Nook. I normally use SD installs for any non-technical friends where there is a good comfort factor in an easy revert to stock.

I actually gave up on ever getting a 32gb card to work properly after I went through several of them. I just doesn't seem like the OS can do a good job with all of that extra space.
Things that fly on a 16gb card are terrible on a 32gb card that benchmarks the same way.

I received my 32GB Sandisk Class 4 micro sdhc card from Newegg.com earlier today and just wanted to report back that it is writing fast. I'm getting between 4.1MB/s to 4.9MB/s on it.

If booting off uSD, you should pay attention on the small write data (4K Write)
If it's more than 1MB/s, it's good.
If it's close to 1MB/s, it's OK.
If it's somewhere around 0.0xxx, then it's bad for NC

I bought four (4) Sandisk32g cards from geeks.com,part #SDSDQ-32GB.They are testing out great.The (4K)writes are 1.277(slowest card) to 1.613(highest card).
($28 /card and free shipping)
I also tried their 16G Sandisk cards,VERY BAD,they test out at 0.024 (4K)write

My Experience Matches Yours

I actually gave up on ever getting a 32gb card to work properly after I went through several of them. I just doesn't seem like the OS can do a good job with all of that extra space.
Things that fly on a 16gb card are terrible on a 32gb card that benchmarks the same way.

I bought two 32 GB Sandisk Class 4 cards from 1SaleADay in October. One started experiencing Force Close errrors on my Nook Color after 4 or 5 months. Eventually it could not even unpack the zip files and build properly. I copied a working image from another flash onto it. It then worked until I started updating and installing apps. It seems that writing to some area of flash, not sure which partition, triggers the start of the force close. During some tests, it would run until I enabled WiFi. I think apps were accessing the WiFi and trying to write to flash.
The 2nd flash from 1SaleADay was used by a relative. I updated all app in December. The relative played Freecell and maybe a few other apps once every few weeks. As soon as I attempted to update apps here in May the Force Close issue appeared. The NC had been running fine with the December updates.
A co-worker bought the NC based on my recommendation. He bought a SanDisk 32GB Class 4 card from a reseller at Amazon. He started experience Force Close issue shortly after mine.
All three 32GB cards had great ramdom read/write 4K benchmarks like other SanDisk cards. I used CrystalDiskMark to test the cards when they were new and when the first two failed. I also ran H2testw on one or two of the first cards that experienced the Force Close errors. All tests indicate the flash is still good.
The first two NCs have been running fine now for a few months with 16 GB SanDisk Class 4 cards I bought in September from Newegg. I need to put a 16 GB in my relative's NC.
I did buy some more 32 GB SanDisk cards from Amazon (not a 3rd party reseller) for $22 a few weeks ago. I hold little hope for them to work for long in a NC. I may try one. I bought them primarily to use in other devices.
The first card to fail has been running fine in my non-rooted HTC Incredible 2 for months now. I use it for podcasts so I am reading and writing to it daily but am not running the OS from it like the NC.
Running the Fix Permission function of the ROM Manager did not eliminate the Force Close issue on my relative's NC.

Thought that was supposed to be the best card to use

You're right. This one is way better, The One To Buy. You should buy that one.
