Hi!
I've found this results of tests of different SD cards and Internal Storage with EXT4.
But what are this test results with default FAT32/ext3?
As I understand, there is no matter to install Uruk on Internal drive or on good SD card (Internal even often better). Is it really so?
And what is means by "metadata"?
BR. Philipp.
good question, I don't know what the metadata means. All I know from testing is that the internal sd is quite fast indeed. Copying large files to the internal 8G, I get speed close to 10MB/s, and reading speed is 12MB/s, that is close to a 10x card, and this is all on FAT32.

Since android is on the storage card, does that mean that apps that are not developed to be stored on the SD-card is being stored in the SD-card anyways? I.e. will the operating system think that the root of the external memory is the internal memory? Cuz that would be great, having such a low internal memory in the HD2 to begin with..

That is what the data.img file that is created when you 1st boot is for, it's also stored on the SDCard. After the NAND loader is released, you'll be able to have some that data so that it can be stored on the phone's internal memory, except the kernel last I heard. Right now the only difference between Nand and SD is that nand is a little bit faster, but you can speed up SD card by getting a higher class card, (instead of a class 2, then get a Class 6) the speed that the device boots is noticeably faster.
the data.img file is treated as "internal memory" for program storage. This file is physically located at the SD card but seen as another storage location. Since there are different flavours of this data.img available (512MB,1GB,2GB) you can easily store hundreds of apps without worrying about phone memory limitations or apps who fail to app2sd (in fact, none of the apps will move to sd on my phone, /care) So indeed, the HD2's internal mem is no problem here.

Got the kingston 16GB Class 10 card, no problems

Thanks, that's awesome.
Though, somehow I see a constant drop inte my 'real' internal memory. I've got a en rom wich i only touch att launch android..
Ok so far Ive found the mod to swap the internal and external sd,
The ideal mod for me is to merge all the 16gb internal into one partition and mount my sd card as a normal sd instead of external sd.
If anyone knows of the mod to do it the way ideal for me please link me. If you are a dev and like this idea would you take the challenge to make this happen? I will gladly beta test as long as a fastboot is available.
You want volume management on a phone?
Just get a big honking SD card. I have a SanDisk 64GB sdxc.
The 128GB cards will probably be available by October.
That said, you can probably get LVM working under Android, but you'll only be able to work with it from the phone itself (no browsing from a PC or putting stuff on the microSD directly w/o totally breaking the logical volume).
You can also format the SD space as ext3, then set up /etc/fstab to mount the external SD on a folder on the internal SD eg, /mnt/sdcard/Music Library. You won't be able to read/write that space from Microsoft (no, e2fsd won't do it), but any other OS can browse it like any other disk drive. Also, the drives will still appear separate from outside the phone.
the ext3 sounds nice but I like my idea better, my idea is pretty much the way samsung/htc/lg formats their storage, one is phone storage, other is sd, not the phone, sd (other internal) and extended sd(actual sd card)
and sorry for some confusion for anyone I meant Extended sd not external, kinda a noob in here coming from a sammy prepaid android.
Iirc in ICS the internal memory is counted as one part. So the 4gb and 8gb will be 12gb or whatever. Android 2.3 and below use the partitioned method.
Sent from my XT910 using xda premium
Edit; therefore wait till ICS comes out
Hopefully this isn't a stupid question, but is the internal SD in ICS a partition or a directory on the system that pretends to be an SD card?
If it's a partition then I don't really see the benefit over an external SD - except where there is no SD slot. Obviously if it's a directory then it would grow as required...
Hope the question makes sense!
Ok, Obviously the question either doesn't make sense, or nobody knows. Or, it's just such a stupid question that no-one can be bothered to answer it... Hoping it's not the first one - not sure how to word it better to be honest.
It's a partition.
Thanks for the reply. I must admit, then, that it seems a little odd on phones like the S3 - where there is an SD slot - to have an internal SD as well. How is this any advantage at all?

In my opinion? Non whatsoever. I find it a disadvantage the apps saves data to the "external" storage, and it end up in the phones internal memory, non removable, lost if the phone breaks down, fixed size, etc. I'd rather see they put this storage to use as internal storage (/data) instead. The storage getExternalFilesDir() returns ought to be ... external. Period.
The internal SD is more of a legacy setting where older and cheap phones have very little storage so large program files had to be saved on an SD card. Now that many phones have adequate internal storage the /sdcard directory is just internal memory that is mounted as a virtual SD card. If the device has an actual SD card slot and adequate internal storage then the real SD card is mounted as /sd-ext. This allows you to swap SD cards easily since no program files are written to it. It is kind of confusing though.
Hi,
is there a way, or did anyone already compared the speed of the internal memory with sd (class10). On my old phone it gave me a nice speed boost to move all apps to sd as it was faster.. same with this device?
Regards
Which phone? Some phones have internal memory as a part of nand, however some have a real sd card integrated inside of phone.
This is my question...I thought that is a good idea to swap internal storage and sd_card...so I could use the real sd with media and (finally) apps...but I ask you if someone has already done it and if after that swap the phone is more laggy...I think that the sd card (even of class 10) is slower than the internal storage...but I can't figure how much slower is...can you give my your opinion?thanks
