Using "mount" to bind external sd to internal memory, are there any speed difference - General Questions and Answers

Using "mount" to bind external sd to internal memory, are there any speed difference
If i was to mount a folder from a class10 64gb micro sdcard to internal memory, mainly to store these oversize obb (game data) files, will there be any problem i should know about. I am assuming that maybe....
1. Class 10 is slower to what ever internal memory phone uses, maybe RAM?
2. It may kill my external sd card fastet if i store frequently access game data files there.
3. Anything elsr?

I did this a week ago with my htc chacha. I mounted the /data dir to the external sdcard (32gb sandisk Class 10 UHS-1) and I can tell you that it works pretty well. My phone won't boot if I use other than a genuine htc battery. I have a spare chinese replacement battery but it won't boot with it. I can't tell you much about sd card corruption, but I had no problems with it. And about the speed.. well, this one ain't that fast anyway, but it's faster than the internal memory that's sure. I had no issues with games, even ps1 games work pretty well on it. Hope this helps you decide. P.S.: you should give us more info about your phone. Cheers!

Hey there. I have a question regarding "mount -o bind".
I have mounted DCIM folder to extSD.
My problem is, the gallery shows up two folders.
And my question is, how to hide folders in extSD?

SD Card problem

I installed a 32 gb sd card and my phone recognized it without any problems but as I iinstalled apps to the card the amount of space in card never changed. I changed the sd card to 8 gb and I'm having the same problem. Anyone else having this problem, I am rooted and have su permission.
Thanks

I am just guessing here, but perhaps those apps are going to the extended internal memory? The G2x (like most Androids now with large internal memory) treats 5GB of your internal memory as an SD card at the directory /sdcard. The external card you put in is found at /sdcard/_ExternalSD
My best guess is that your apps are going to the /sdcard which is actually part of your internal memory.

You are right, how do I put them on the ext sd card? Do I have to partition the sd card or is there another way, seems the people that don't root there phones must be able to use the ext sd card as well??
Thanks

Sorry, but I can't answer that one yet, I haven't even ordered my G2x yet. I just read about this issue from another thread on this forum because apparently it was the same setup on the Vibrant. Perhaps some Vibrant owners can chime in with a suggestion? Not sure if it's possible to put apps to SD or if they just automatically go to the internal storage. However, if I were you, I'd rather have the apps on internal storage and save the SD for videos, pictures, music, etc. The internal storage will be more reliable (not fail later) and faster than the SD. 5GB should be more than enough space for app storage.
App2sd works. As long as the app supports it. But there really is no need to put them on the external sd right? 5gigs should be plenty. Put your music and vids on the external. Sounds exactly Like my vibrant.

Yeah, that's what I meant but I think I used the wrong term. When you use what Froyo calls "Apps to SD" it goes to what the phone calls SD but is actually internal memory. Do you know if there is any way (without root or hacks) to have those Apps to SD actually go to your SD card (/sdcard/_ExternalSD) instead of the internal memory the phone calls the SD?
I agree that the 5GB internal should be more than enough anyway, but I am curious for sure.

I just never had that set up before with any of my android phones. I just didn't know how to put any files to the ext sd card, I foolled around with it and basicly I just went into my file manager and long pressed the app of file, copy, went into the extsd card and paste.
Thanks for the help.
I have had the MyTouch 4G and the Nexus One, neither had that set up.
PS this phone flies.

It doesn't come with any sd card. Supply your own.
i thought the 5 gigs was for storage and the 1.5 was for apps? i'm confused
wow, sweet phone with no sd card or headphones. lame!!
ps, still gonna get it tho =)

Yes, this is true. However, from 2.2 up, Android allows you to move apps to the "SD card" (or in this case the 5GB extended internal storage) as long as the developer enabled this feature. This way large games and other such apps don't use up all the storage.

Not many phones come with an sd card and besides why use their ear buds when you can get a pair of zipbuds from amazon?
http://www.amazon.com/Zipbuds-DGA-T...8N9G/ref=sr_1_1?ie=UTF8&qid=1303274745&sr=8-1
Furthermore it's none of my business and you're free to do as you choose but who sticks their apps on the external sd card? Why do that?

Having a Nexus One I put most of my Apps on ext 3. Worked great and always had over 140 mb of free memory space which kept my phone very fast.

I think the idea is your apps/data go into internal 5GB (which is mounted as SDCARD) and then you use your SDCARD for media (mounted as /SDCARD/_ExternalSD)
yup.. that is right mobilehavoc.
The phone has no "sdcard" when you get it new, but it's got basically 5.35GB internal SD already built in.. So you have plenty of storage, plus you have 1.3GB for apps, and can move them to that 5GB if needed.
Although I just put in my 16GB and tried to titanium restore and it doesn't find anything cuz it's looking in /sdcard and my file is on my sd card, and the g2x has that as /external_sd
that is irritating, will I need to move all the important stuff over, and downloads and pictures n such will all from now on go to the internal 5GB. so move everything over and use actual SD for rest
Hey there, so I'm having a different sd card problem, but I can't find any threads directly related to it so I'm just going to post it here because it seems just as good a place as any.
So yesterday morning, about 3am or so, cause I'm weird like that, I finished the movie I was watching, so I went to go move it off my phone and put another one on, so I hooked up my USB and connected to Ubuntu, the sdcard popped up and I deleted the file, then deleted the trash file but when I delete the trash file I get an error message saying Error removing file: Directory not empty, and no matter what way I try to edit my sd, it won't change, it won't save any new data or delete the old, I've tried reformating with the phone, reformating with ubuntu, I've tried file managers, using a micro to sd conversion chip and putting it in my card reader, but no matter what I try my sd won't change, somebody please help me out, I just got the 16gb card like a month ago, but I bought it in Austria so I can't really return it, because I'm living in Italy.
Thanks in advanced.
Never mind my last post, I did a wipe of my sd card from the phone, pluged it back into ubuntu, and then magically, I could erase all the files.
This setup of this phone's memory is frustrating. I have an app called DroidTV which normally uses the SD card to save videos to, but due to the internal SD card it's getting saved there instead. Is the only way to change this to hope the app developer fixes/changes the way the app behaves? I wish there was an option to make the phone treat the internal SD as the external so you could more easily use your larger card as the default

See it's really a hard problem to solve. I'm coming from an Incredible which had 8GB of internal storage but it was mounted as /emmc. This meant no app except the custom camera and music apps and maybe one or two apps specially designed by devs could use the internal storage.
The way the G2X does it, all apps can see the internal storage and use it. All media apps can see the external SD as well. But you are right, the dev would need to update the app. Although I don't see why it is so difficult - they could give the user the option to a path so you could put in /sdcard/_ExternalSD/
And that would work.

Internal Storage 2GB? Why Is that?

So I managed to get a ROM going on my tab that came today, and all is pretty good so far. One question tho; I went to my settings --> SD card usage or whatever its called and my internal memory is showing 1.79GB total space.
My SD card is 16GB and that's showing up fine as 14 or whatever FREE, since I partitioned at 2048/0.
I don't get why the internal storage is 1.79. Shoudn't it be 16GB or whatever since that's how much this tablet has? I'm confused.
Thanks!
I may be wrong on this (Developers, please correct me if I am wrong) but I think the 2GB is reserved for the Android system and the remaining space is what you can use for apps, etc.

if thats the case, why won't it show the remaining 14G or whatever hmmm
The 16gig is divided as 2gig for apps and 14gig for storage (/sdcard). After format and overhead you get what you see.

So how do i mount my internal? Im only able to mount my microsd card..
Actually I take that back. I can only mount my internal storage to my computer but not my microsd card. I have no idea how to do that...
That's normal behavior for the gtablet. There is no built in method for mounting the external SD to your computer.

Changing internal for external memory

This is something that my friend has done in a SGS to increase the system memory the phone. It seems a good idea for those who like to have a lot of apps,games and gps maps installed and don't want to move all apps to the sd external memory everytime we have to install more games.
The theory is simple, we have to edit a code line and prepare the external memory cloning the internal one. But I have some questions:
- I'm gonna use a class 10 microsd. But which format it will be the fastest? Fat32 works really well, But ext4 could be faster and safer...or what?
- Have anyone of you try this for a long time? I'm exceptic about performance and durability of the microsd memory...
- What would happen if I try to remove the microsd in the system settings? It will remove the microsd, or the internal memory?
- And if I plugged the phone as a massive memory? In the pc should appear internal memory as external memory, or what?
I'm waiting your answers

Problem with moving apps to external SD card

So apparently Samsung makes the skyrocket think that the usb storage is the sd card. Because of this when i tap to move an app to the sd card it moves it from system storage too usb storage. I am pretty much out of storage internally. Has anyone else had this problem or does anyone know how i can solve the problem.

I do not think that Samsung is unique. An external SD card appears as a directory in the external storage. It is rather easy to use this directory to store music, photos and videos. I have many programs and I am nowhere near tapped out in terms of storage. However, I believe that there are a number of solutions that would allow one to move applications to the external-external SD card.
Ya i was wondering if anyone had heard of a way to do this. I havent found anything yet.
If you are rooted you can probably edit the fstab file to switch the mount points of the internal and external memory. This has been done on other devices and a search should point you to directions to accomplish this.
There are negatives and positives to this approach, so read and understand what yoou are doing and the effects it will have before doing it.
I have over 80 apps installed, including two nav programs with offline maps for the US and have 1.5 GB in the user space for ap installs, 9.4 GB in the internal storage, and 11 GB free on a 32 GB external SD card (music files take up most of the used space).
Thank you!

[Q] APPs to SD (external SD)

I have lots of games (most of them 3D) so I have to download a lot of Data.I tried to move the apps to the sd, thinking it might free up some memory in my internal memory of only 16GB ( I have 32GB external SD card). I quickly found that they apps are not installed in my external sd card!? They are all in my internal sd card (which I thought as my phone memory). I realized that samsung phones have an sd card inside as their memory, so the system can only move from phone to internal sd card.
I am trying to figure out how to move an app to external sd card.
Anyone has any clue??
I had the same problem, never found a solution...
BUT, just move all your music, videos, and other files to your external sd card and the 16gb internal sd card should be more then enough to have all your 3d games on... thast what i do.
Don't forget, there's still 2gb of nand memory in there that holds all the pre-installed apps plus any that you don't move to sd. Personally I keep all my games and 3d apps on the phone memory (tip here, nand is faster than flash) and all the less critical apps on the sd.
Ok after a lot of research I found out that you can't do it without ROOTING!!
After rooting there are lot of apps which can move your apps to external sd.
I am not going to root so I guess I am stuck ...
Thanks Android for such options
