I have rooted my nc and its running android 2.3.7 on a sd card. There are times that it works great, but there are times when I click on an app it freezes and I have to do a hard reset. What could be the problem.
What brand is your SD card?

That is your problem they only SD card with good performance is a Sandisk class 2 or 4 8GB or above. There isn't really anything you can do other than get a new card.

Gotta go with Sandisk as well.
Tried Transcend, PNY and Kingston cards of 4-16G capacities and c6-8 speeds and they're all handily beaten by my Sandisk cards so far as stability.

i get alot with my transcend too. where would be the cheapest place to buy the 16 GB?

It is speed. Sandisk has the fastest random write speed which is what seems to cause those lock ups. SD card class is just measures one (relatively unimportant) indicator of SD card "speed" (sustained read).
Sustained read and write are great if you're using your card to backup large media or picture files but more or less worthless for running an operating system. Same principle is in place for SSD. Manufactures advertise sustained transfer rates but the important stat for a OS drive is access time (which determines the speed of random read/writes).
Here's a link to a 32gb sandisk for $30 http://slickdeals.net/da/mem-i/p46847290/k4569/u125110/r4
These work just as well as the 16gb ones.

32gb is theoretically the maximum, since 64gb cards will all be part of the new SDXD standard. Then again, several people have found that the 64gb SDXC cards work in their SDHC devices so we'll just have to wait until someone tests one in the nook color to know for sure if it'll support it (I wouldn't hold your breath, our hardware is fairly old).
I can certify that the 32gb works fine, as can numerous others who I've seen post.

Hey guys, I ordered my 32GB Prime, super excited about it, and I want add another 32GB memory card but I don't know much about the different classes. Is there a huge difference between them? Thanks for any advice.

From Wiki:
The Speed Class Rating is the official unit of speed measurement for SD cards. The class number guarantees a minimum write speed as a multiple of 8 Mbit/s (1 MB/s).
Classes
Class 2 - 2 MB/s
Class 4 - 4 MB/s
Class 6 - 6 MB/s
Class 10 - 10 MB/s
Click to expand...

Basically the Class you "need" will depend on the kind of data you will store and how do you plan to use it... For storing and editing plain docs I wouldn't mind having a low class SD, but it would make it harder for your TF to write other files as HD Videos as fast as it should.
More info here:

Just make sure it's a Sandisk micro SD in my opinion. Their C4 cards tend to be a lot better and more reliable than most peoples C10 cards.

Well I'm not saying I would buy one of those, the cost is prohibitive, just wondering if it was even an option.
you can get a class 10 for $40-60, so even if the Prime cannot use a class 10, why not buy it to future proof the purchase and then when something comes along that can use a class 10, you have it.
Iam looking for a well rated, 32gb class 10.
Hopefully it will support microSDXC, so when the prices of them start to come down we can extend the memory massively!
Just format the sdxc with a file system the Prime understands. sdxc is just using exFAT. I'd format it with FAT32 or NTFS (if the Prime supports it).

The SDXC card was tested on the TF101. No problems there. I'm pretty sure it will work on the Prime as well.

From what I understand, SDXC just added the exFAT requirement for the for it to be SDXC. From what I originally read awhile ago, sdhc hardware will support 2TB cards. There are a lot of people using the 64GB MicroSDXC and 128GB SDXC in devices at said that they only support SDHC cards. They just formatted them to a file system the device can understand.

I have a SanDisk 32GB Class 4 MicroSDHC, works perfectly and doesnt slow down the phone.
I have watched 1080 video via MHL from the SD card.
Yes, 32GB is max. Open case so you can see what sdcard goes inside. No it doesnt make your phone slower, I think. But 32+16 GB is too much, so it might lagg a bit.

As long as the SD card has good enough random reads/writes it wont slow the system down at all (aka as long as its a good card its fine, aka the Scandisk ones are a safe bet, and actually the lower classes have better random read/writes).
The only thing is that if you have a lot of media the media scanner will take longer to finish (derr).
Thanks everybody, was also gonna ask the same question.
Nope. Sandisk 64GB micro SDXC works just fine with SGS2. However, I digress...
I concur with Veyka, my Sandisk 32GB/Class 4 works more than admirably for pretty much any/everything I've thrown at it so far. And they're fairly cheap too (<$50 AUD for me).

It's better to take some class 6 or class 10 card (but class10 is abit expensive and its almost no difference in most cases on SGS2).
The card will not slow your phone by itself, but a lot of files or media can slowdown mediascaner abit and increase battery consumption by mediascaner.
Just wanted to jump in with a reminder. The class rating of the card refers to the write speeds. So the class is irrelevant when you're talking about the performance of opening/reading files. The class is only relevant when writing to it.
That said, get a brandnamed card. I recommend Sandisk. I have a Class 2 32GB Sandisk that actually performs (from my testing) faster than a Class 4 rating.

Yes SD card classes shows minimum write speed (because before classes some manufacturers was "cheating" using "×" as read speed)
But read speed usualy almost equal to write speed. So reading from class10 card is for sure faster than reading from class 4 card. Just check this article on wikipedia. en.wikipedia.org/wiki/Secure_Digital#.C3.97_rating

That appears to be on a case-by-case basis depending on the card manufacturer.
From my own testing, my Class 2 32GB card can write at about 4MB/s (which is on par with a Class 4 card).
I also have a Class 10 8GB card which obviously can write faster than the Class 2.
But both of them are neck-and-neck when it comes to read speeds.

Cheers MB. I've been looking at them on eBay but thought class 4 may be a bit slow. Think I may get one now. For about $40 aud they are a bargain.

NP ;-) I paid a bit more than that for mine ($48 @ MSY from memory), so you're doing well if you can get one for 40 bucks.
I don't see the point of paying a lot more (double and more) for a card with a higher class rating for pretty much negligible improvement in "performance". We are talking about a phone after all, and this card handles 1080 video (recording it/writing it to the card) just fine which is probably the most "intensive" activity the phone is capable of.

I have a Samsung 16gb class 10........ its the best card i've had... All i will say, pay a little more for a good brand, or your next thread you will be complaining about errors and sd card problems
For normal day to day usage in the phone there'd be very little difference in a class 4 or 10 card. However copying 32gb onto a class 4 card is a slow progress !! Spend the little extra and go class 10.

Didn't want to wait for one to arrive off eBay so a mate told me to go to Centrecom (Australia, Melbourne). Bought a class 10 for $50. Tests show write at between 10-11mb/s and read at between 18-20mb/s. Pretty happy.

Don't forget to reformat the card in your phone - or else it won't work.

I wish I knew what brand that class 10 card was. It's garbage. I just ran that tool thrice and my average read/write was 10.9/4.9MB/s respectively with a Class 4 SanDisk 32MB. That said, I'm also pretty pissed I paid 65 dollars for this card when I could have gotten better speed and more powahhhh for not much more if I waited. FML.
In case anyone doesn't know, the class rating on these cards is the minimum write speed the card will achieve, provided you're not copying a movie from a USB 1.0 PC or something else that would bottleneck it.

To be fair you can't go with the read/write on a card unless you test empty. My 32GB card surpasses the Class 10 it is if empty but get near full and it' just below a Class 6. So the tests mean absolutely nothing unless you are testing with an almost full card. It's time I moved to a 64GB card my 32GB is too full with the games on it.. LOL

The term used to measure performance escapes me right now, but they said it was more important than just the fact it's a Class 10.

currently i have a 32gb class 4 sandisk and i have some epub format ebooks that i am reading now with aldiko. turning pages are pretty quick. the general rule of thumb is this:
if you care about file transfer speeds as in copying/moving files from a hard drive to your sdcard, the higher the class the better.
if you care about performance as in how the files are read which in your case is what i think you want, class 4 or class 6 is the sweet spot.
Also wasn't there some issues with higher class cards and stye NT clashing? I think general consensus is that the class 4 works best the the NT.

I'm just a noob , but I think it also depends on what you're running. I dualboot and run CM9 straight off a SD card. I read sequential read/write is what essentially makes the class 4, 6, etc. But for running a ROM on it, it's all about random write. SanDisk is recommended in this case.
But by all means, check for yourself. Hope that helps.

Class 2 for SD video recording
Class 4 and 6 for HD ~ Full HD video recording,
Class 10 for Full HD video recording and HD still consecutive recording
UHS Speed Class 1 for real-time broadcasts and large-size HD videos
Our beloved Nooks can't do any of that. The general consensus is that these such devices just weren't designed to take advantage of the higher speed cards. The test results in the chart referenced earlier bares that out.

Same here. There's an old thread on XDA somewhere that tested sd cards and r/w speeds. It was SanDisk hands down, class 4, either a 4 or 8gb. It was found that for these tablets booting from the sd card, the class 4 was superior to 10's.

Either try a different file system all together, such as Ext3,or try formatting the SD card with your tablet.
