Interesting! Never seen one before. Oh well, so how big do you want to go to? With storage it is always good to get the most you can afford.

Usually, a good seller like Amazon will let you return it so it is pretty safe to try new things.

iwan't to buy 16 or 32 GB class 10 but i'm from Egypt and unfortunately amazon dose not support any vis here and paypal too dos not support Egypt yer :(

so i'll try my luck with any local seller

have another question please :confused:

sandisk in Egypt has maximum storage of 8 GB

and Kingston and transcend is more common here

do you have any idea which one is the best ?
[Android General] NYLimited:
That is a tough one.. While both, Kingston and Transcend should be a reliable cards I have seen people report issues with a lot of them. I have no first hand information on using them - have used Transcend in cameras but not in a phone. Unfortunately, using a card in a phone with Android is quite different from a camera so it is hard to guess how it will perform. Most manufacturers design and test for cameras. Would any of the local dealers be willing to take the card back if it does not work reliably for you? If possible that would be a key for me.

Newbie

Hi guys..im just newbie on android phones..

just want to ask if the classes on SD cards affect the games on androids?

i.e class 4 sd cards cant run on specific games? like that?:confused:
[Android General] NYLimited:
A game can run on most any card, albeit some may be a bit slower.

Since games rely a lot on reading a well picked read buffer will go a long way. If *only* used for the games, not for Android, try a good Class 10 card. If Android will be on it also stay with a Class 4 or 6.

I bought Sandisk Ultra 32GB class 10 microSD card, installed various version of Native SD android ROMs, but I still think that NAND is faster? Is it just me?
[Android General] NYLimited:
Yes and no.. :)

First, if you didn't use NativeSD you could not have had all those ROMs in NAND so no matter what it is faster than not having it.

But, seriously (and I don't know what device you haveI just saw your signature so I know):

I know your device cannot truly take advantage of the UHS-I speed which requires a specific voltage to be enabled. If the card does not get that voltage it will only operate as a Class 10 device

UHS (and Class 10) were designed for sequential access, very large files like videos. Android has no such files. Android mostly reads and writes small files - random access. Your (downgraded to) Class 10 card is likely operating more or less the same as a Class 4 or 6 card would.

So, depending on your device NAND speed it is quite possible that you are right. The HTC HD2 operates at roughly Class 4 speeds in NAND.

If you needed only one ROM, using DataOnEXT with a good Class 4 or 6 card would be faster because you would take advantage of two fast access devices.
[Android General] bojanbl:
OK thanks for the info ;)

I have another question... Do you know which cluster size for SD card is the best?
[Android General] xxalexdomxx:
Thank you for this info! I'll be getting a Class 10 asap :)
[Android General] bassamy99:
i just take my chances and bought transcend SD card i just installed a Native SD android ROM and just it working little bit faster than older one but working fine till now

thanks for your help
[Android General] NYLimited:
That, to a large extent, depends on the size of the card you are using.

If your card is less than 8 GB you can set it to 4 KB.

If your card is between 8 and 16 (but less than 16) GB set it to 8 KB

If your card is between 16 and 32 (but less than 32) GB set it to 16 KB

If your card is 32 GB or larger you should set it to 32 KB

Slow card

What device is this? How is load time from NAND on it?

There can be many reasons for slow response from the card, not the least of which is the card itlsef. What brand card is it and what size? Different brands respond in different manner. The cluster size of the card (which is tied to the size) also can impact the response.

More traditionally, Android can load slow if it is running short on memory and needs to flush unused apps before loading the new one. Check

post # 45

in this thread, specifically the second part of that post for MinFree settings which can greatly impact performance.

I am sorry if this question have an answer here,but on CM9/10 I get random SD Card Removed. What can I do?
[Android General] NYLimited:
I cannot be certain based only on the info you gave but my guess would be something to do with the specific card. The card might be bad or not sitting in the slot properly or simply 'powering' down' to save energy at times.

Have you tried to completely format the card in a PC? Sometimes that may help but some cards simply need to be replaced.

Better yet, if you have a chance, try another card and see if it does the same thing.

:silly: :silly: :silly:

I've been trying to use my SDcard to do the internal memoory increase trick because my Samsung Admire (Mid-range HVGA) android phone (armv6) is really slow and almost always running outta space.

I think this phone would be better with 1.09 GB of storage.

Do you know how to do that?

If so could u make s imple tutorial for us (by that i mean me :P) noobs.

Or a Vid :P

Thanks In Advance. :highfive:
[Android General] NYLimited:
I don't know your phone so I would only be guessing. You might want to check in a forum for your device..

Is your device rooted?

Does it support init.d scripts?

What Android version is it?

Are you running a custom ROM that you have the zip file for?

v 2.3.6

no custom Rom and no file.

also i tried rooting but i have to flash CWM into my device and then with it flash the root thing and i tried and failed....... :crying:
[Android General] NYLimited:
In order to change internal memory to your card your device must be rooted:

As it is now you could use one of the apps on Google Play to move some things to the card but they would be in a slower file system and eventually you will still run short on space.

If you haven't tried yet look for Apps2sd (there are several) on Google Play and try one. As long as it does not require root it will buy you some time.

The other alternative is to learn how to root the device but you need to be more careful with that.

I 'd say start with Apps2sd and read more about root.

[Android General] NYLimited:
Yes, but not for Android phones, at least not yet. Maybe a future generation of phones will improve the card bus although Android will always remain largely a random access system by nature. Overall, today, for most devices we can buy, even Class 10 is overrated. :(

Lexar microSDHC

isn´t this the Lexar microSDHC 300 faster than a class 10 card? or am i missinformed? in the specifications it says 45mb/s

(just look at amazon because i can´t post any urls yet)
[Android General] NYLimited:
That Lexar card is a UHS I card. This is a different rating fro the older Class x ratings. Yes, the card does claim high speeds (up to 45 MB/sec) as do most of the UHS cards. Unfortunately, most of today's cell phones are not designed to supply the higher voltage requirement of these cards so, to begin with, most will operate at a stepped down speed.

You should also note the manufacturer's notes about the card: "Mobile devices are increasingly being used to capture all of life’s important moments, and the expectation to capture high-quality video is becoming the norm, so people need a reliable and efficient way to store and manage this content” which suggests video and audio, both of which are essentially sequential access formats. The Android operating system is mostly random. Benchmarking these cards with large sequential files or streams will yield much better performance than the smaller random blocks used by Android.

Imagine an ultra-fast race car trying to navigate the old, small streets of London - they will never achieve their 200+ MPH speeds.

:)

So, while the specifications are technically true they may not be of much help to you and I.

[Android General] NYLimited:
You might want to look at scripts which could be executed during boot (if you have init.d access and root). Something like this may work:

find directory -mindepth 1 -type d -empty -delete

If executed from inside "directory", it should delete all empty directories below (a directory is considered empty if it only contains empty directories). The "mindepth" option prevents the directory itself from being deleted if it happens to be empty.

It should be noted that I did not test this script so be careful with it!

I'm currently using a Scandisk 8GB SDHC Class 4 card,

ROM: NexusHD2-JellyBean-4.1.2-CM10 V1.3a, NAND with DataOnEXT

beside that I have a Transcend 16GB SDHC Class 10 card

in your Opinion should i keep my current installation?

or switch to the Transcend card?(either with the same Nand with DataOnEXT or switching to NativeSD

thanks again :)
[Android General] NYLimited:
I assume you have CWR or TWRP installed and working, yes?

If you do, make a full backup of your system. When done copy the entire fat32 portion of your card to a PC (including the backup you just made).

Now you can format the 16gb card (create both fat32 and ext4 partitions), copy everything back to this card from the PC.

If using TWRP you can now restore only the sd-ext partition. If not, restore all.

Now you can try the 16gb card (which is also bigger) and see how it does.

If you don't like it you can easily switch back now. Always nice to have that backup! :)

in your opinion should i try the Transcend 16GB SDHC Class 10 card, what i wanted to do is to use NativeSD

would you recommend it?

or should i stick to my current installation?
[Android General] andrefrsousa:
Hi,

Thank you very much.

Regards,
[Android General] NYLimited:
The read speed of that card is good.

The write speed is a little slower than I would prefer it, not sure why.

The questions you need to ask yourself is

Do I need the extra space 16 GB would give me?

Is the price good (cheap enough) on this card?

If the answer is yes to at least point b) I would give it a try. I am not sure the speed increase would be significant or not (depends a lot on your device also - not all HD2s are made the same and some are capable of faster I/O speeds than others) but if the price is right you would have a spare card, at the least. :)

As for NativeSD - it is great if you have the need or desire for several ROMs at the same time. I prefer DataOnExt because I do not use multiple ROMs and DataOnExt gives me two memory devices instead of just one. With NativeSD, even with a faster card, everything (system, data, Dalvik, cache) come from the same device, creating a contention for the controller.

I have 2 HD2 512. One is mine and the other belongs to my bro but they are the same .. my bro had a 8gb 4class card and and me 8gb 6class. So my bro had problems bugs and sods and reboots etc. for a long time with his 4class card. I decide to buy him a 10class sandisk and fresh install a rom again to his hd2 and BOOM the ROM is super fast and everything is working well. I saw that and i bought one 10class for me too .. i install the ROM and the Rom is not so fast, full of hot reboots, sods etc. i have try 1.000.000 Fresh installs and i can't make it work like my bro's HD2 ..

SOMEONE EXPLAIN ME WHAT IS WRONG. (for now im back to my 6class card)

same phones same cards, different girlfriend's.

Rom: [ROM][AOKP JB 4.1.2][01-25-13] Dark Glass ONE 0.2 [NATIVESD][DATAONEXT][BEATS AUDIO] its a stable rom btw.
[Android General] NYLimited:
The problem is the different girlfriends! :laugh:

Seriously, I don't know if there is a simple answer. Your two HD2s are not the same device - as a result there can be differences in their components and how their bus handles the card speeds.

Additionally, they likely have different sets of bad blocks which makes the NAND memory work differently.

Are the two cards you bought the same? If not, that can be a significant difference but, even if they are, cards can be different among the same brand/speed class.

Lastly, are you quite certain all the settings are exactly the same? Buffers, minfree, etc.? They too can make a large difference at times.

If the cards are exactly the same and the NAND partitions are large enough I would try formatting everything for the second device (including the card) and would try to restore a Nandroid backup taken from device 1 to device 2 and see if that makes a difference. If this fixes the problem the two HD2s were not set / formatted / configured the same way. If it does not the two devices are at least slightly different as far as components are concerned.
[Android General] zoUphd2:
Hmmm my friend .

I have think everything that you wrote ..

The card are definitely the same .. and the same way formatted.

About the phones im not sure but the are boughten from the same store. I have try everything .. except the backing up from my bro and restoring to mine. I will do it and i will post you some results. Really appreciate for fast respond.
[Android General] NYLimited:
I will be curious to hear what you find.

Incidentally, do you know if the chipsets in the two HD2s are the same?

(You can tell from the tri-color boot mode display - if you see PB81120 SS-B3 on the first line that means your NAND Flash ROM is from Samsung (KBY00U00VM) and if you see PB1120 HX-B3 on the first line your NAND Flash ROM is from Hynix (H8BFS0WU0MCR))
