I use my s3 mainly for music and camera video, the size of the internal memory is more than enough, so which is more efficient in terms of use and battery?, just use the internal memory alone with faster read and write then remove then sdcard? Or just keep the sd? Isnt it will just consume more power since you are running both reader especially when listening to music for long period? The only advantage of sd is you can remove it along with your files if the phone broke down, but since i backup my files most of time i dont think its an issue, cant decide, give me opinions pls
!!ALL QUESTIONS GO IN THE Q&A FORUM!! OR THEY MAY BE DELETED!!
This is a strange question. Reads / writes on an external sd card will not use more power than read / writes to internal memory.

Best reason not to use the internal storage is if you have the insane emmc chip, you're less likely to have problems with bad memory blocks if you keep everything on the external sd.
Yes but if it reads faster, the time it spends reading will be reduced, based on my benchmark, internal read is 32MB/s as compared to my sd class10 which is 14MB/s, and since it will always read the internal because that is where the system apps is right? So adding an additional sd will just consume power, i got my sd from my previous phone, just doing some powersaving on hardware side since as much as possible i want to save power. Just updating for info

I thought when using ext sdcard, the device need more power.

Technically yes, a read / write will be quicker on internal so the same operation on both, the external would take longer so would use a modicum of "extra power". 2 minutes of iops on internal will use the same power as 3 minutes of iops on external.
Since iops on solid state memory use almost 0 power, by not using an sd, you're not at any advantage

Why would you think that? The internal nand flash is the same type of memory as an sd card.

It depends on the class number written on the SD card.

It could be argued they run slower on the SD card. Needless to say this phone has plenty of onboard storage for apps. And some apps don't support the SD card. The only apps I have on my SD card are the incremental backups from TiBackup.

I completely agree with nerozehl. Put everything on your internal storage.
Another con of installing them to SD is that, if the app is important, then your phone won't function "properly" when you plug it into a PC under some configurations (like when your PC reads your phone's SD card). Important or not, the apps installed to SD will most certainly not run in those scenarios.
I can't think of any reason to install the apps to your SD Card unless you really insist on installing like 500 different apps and you use up the internal storage, which is incredibly unlikely.

Wow, your HDD only weighed 10-20 milligrams??!
Typo aside, keep in mind that EOL on the TBolt will be in ~1.5 years (and that's probably stretching it). You're comparing storage from a system ~25(?) years ago, not 1.5 years ago. The 8GB (actually 4GB) of storage will last that 1.5 years just fine. Even if you try, your phone will run like crap before you fill up that storage.
Increase performance?
I've a 32GB class 10 sd card, very curious to know if having another place for apps to load from would increase or decrease performance?
Thank you

Hi guys
I'm looking to buy a Micro sd card, samsung 32GB, class 10
So my questions are:
1- If someone already using sd card just like this one, tell me is it working fine with your android device?
2- Do you think that patriot or some other manufacturer cards are better then samsung?
3- Does your phone in some cases really feals faster with an sd card with bigger class number ( does reading speed of your card effect phone's speed? )
4- I heard that class 6 ( 6 MBps ) is more than enough for android devices, and also that some class 10 cards slow down a device, is it true?
5- Will i ever have enough memory on my phone
I know that there are the same threads on forum somewhere, but i need answers quickly and thats why im opening this one..

1. It works fine.
2. It just user preference. Their both great.
3. Reading and writing to the SD card will be faster. It won't affect phone speed unless your device is using certain mods such as swaps, int.ext. sd swaps, etc. or you have apps on your SD card.
4. While class 6 may be quite fast for a device, there is no way a class 10 could be slower.
5. That's up to you .
tnx Theonew
if i understood it well, an app called swapper 2 can allow device to use some memory from partitioned sd card like a ram memory and provide it a slightly better multitasking, and speed.. ?
And i have read that it can also affect an sd card's life..
So, is it worth it?

Yes, swapping can degrade the life of the SD card but it is worth it if your device is a low-end one (and slow). It will assist in stuff like gaming, etc.
No, I really don't think its worth it. It really affects the cards life and does not really add much ram, even for slow phones...

An additional 256mb is quite a lot compared to 192mb (total).
Quick benchmark of Samsung SD card class 10 in the ASUS Transformer TF101.
Code:
[email protected]:/home/kuisma# hdparm -t /dev/block/mmcblk1p2
/dev/block/mmcblk1p2:
Timing buffered disk reads: 60 MB in 3.09 seconds = 19.43 MB/sec
Reference, the internal nand flash (/data partition):
Code:
[email protected]:/home/kuisma# hdparm -t /dev/block/mmcblk0p7
/dev/block/mmcblk0p7:
Timing buffered disk reads: 52 MB in 3.10 seconds = 16.79 MB/sec
If comparing read vs write, large blocks vs small, sequential vs random etc, the SD Cards wins a few times, the internal flash a few. It's more or less a draw. I would say this SD card got "good enough" performance, although far from SSD performance.
good enough for smartphone

Hey there.
I'm a little confused regarding the internal storage of my VZW Note II. It has 16gb, which I know is less when formatted... there's around 10gb available for apps and files. Isn't that the partition sizing for Samsung's massively bloaty ROM? I'm running AOSP; is there any way to reclaim some of that space? Or I've seen some stuff about dual-booting, but there are way too many disparate GNoteII forums on XDA and I can't find any specific font of information. Is that a way to more efficiently use space? I'm just consistently crunched for space since nothing can use the external SD really, and 10gb goes away quickly nowadays.
Thank you kindly.
I would like to know the same thing. Just flashed and rom and set everything and now I only have about 700MB free space. I don't even run lots of apps. It's the miscellaneous that takes up majority of the space.

Thats 700mb freespace for the system partition which is plenty...apps reside on the internal sd which you should have 10-12gb free.

Exactly. That's 700mb to /system, then the rest goes to app storage and the emulated internal SD card. My phone reports that at 10.33gb total; 10.33gb + 700mb = 11.03gb total known storage across all known partitions. Doesn't that seem a little low?
I know my phone has 2gb of ram but what I am speaking of is the 16gb internal SD storage.

That's what we're speaking of as well. Your phone has 16gb of internal storage which is split across system files and app storage. Any space left over is your "internal SD card". It's how Android works post-Ice Cream Sandwich.
no its not low thats normal...
Well, I know our "16gb" cards are only 14.9gb, marketing considers 1gb = 1,000mb's, but it's really 1024 mb's. So really if you do the math, 16gb by marketing definition equals 14.9gb in reality (16*1,000^3/1,024^3). That explains 1gb at least.
I'd imagine the rest is the baseband and radio software, all that? Is the touchwiz framework always left on the phone even after a full internal format?
How much available space does a "16gb" Nexus 4 have on first boot?

Ah. I did not realize that the RAM was part of that 16gb as well, I thought it was dedicated. That explains it. Thanks

Where'd you see that?
Well according to the email notification I got from XDA, droidstyle's response was:
"no its not low thats normal... The rom is 2gb + 2gb of ram + all of the apps leaves arouns 11gb free."
then when I went to reply that second part wasn't there anymore? But I assume droidstyle is right? 14.9 - 2.0 - 2.0 = 10.9, so... closer?

It seems weird, but I think you're right. It's not only the most logical and mathematically accurate solution, but thinking back on it I believe that's how my poor old Galaxy Nexus functioned as well, it was just far less noticeable since the Gnex had 32gb of memory and only took 1gb of RAM, vs. 16 - 2.

I have a 32 ultra SD, so I'm pretty set. Currently I have 4.9 GB available on the internal drive. I like to keep a clean drive. If you download music, most if not all will go to the internal. I've looked for mp3 apps that direct the DL's to the ext.SD, but have only found one, and that one didn't work. I believe cache goes on the internal too. Every time you download a ROM like meanbean, liquid smooth, they place a folder on the internal drive. They're empty, but they take up space.
I think the ram is part of the internal.

Oh I have a 32gb Class-10 µSD card in my phone right now. The problem I'm facing is that any sort of app storage can't be moved to external SD... I have one or two pretty massive games and a lot of apps that love to cache reserves of data, and it adds up. I only have about 1.2 gb free storage after clearing all caches, without really any other files to speak of besides a few pictures. Oh well, I can deal. I was just spoiled with storage on the GNex.
I have a Samsung Galaxy light, and it is rooted. Yeah, this is a relatively low end phone that cost me about $50 a year ago, but it still sometime seems a bit slower than I think it should be unlocking the lock screen, or loading apps.
I used the app Android A1 SD Bench to benchmark the SD card and internal memory. Here are the results.
Exteral SD card ---------Read 37.1MB/s Write 11.88MB/s
Internal memory--------Read 12.31MB/s Write 1.62MB/s
SD Card (see note)-----Read 19.39MB/s Write 2.26MB/s
Now I'm not quite sure what the SD card item was, the total size was identical to the internal memory, but with a 20MB difference in free space, so I assume it is some other reference to the same internal memory, but it somehow performed faster.
Either way, you can see, according to this app at least, that my SD card is way faster. Any good ways to take advantage of this without getting too overly in depth?
