[Q] InsertCoin MAX size for ext?

Hello !
Sry for posting this here.. I'm still too new to post on dev threads =(
It's a question for ppl who use InsertCoin..
I got a 16gB microSD yesterday, so I want partition it for more ext..
But I saw this.. www[dot]miui-au[dot]com/faq/a2sd
If you go over 2Gb you may experience SD Card corruption and the Market will not operate properly!

And I saw somebody saying that the maximum ext that I should get is 1.5 gB at InsertCoin's main thread.. I'm not sure.. (I couldn't find that post anymore =\)
Does anyone know if there's a limit for MAX EXT using InsertCoin?
Thanks a lot !

I concur, more than that is a waste of space and decreases the r/w speed.

1 GB is recommended, in my case i use 2GB as i need space to sync my emails and other data. As rightly mentioned by paul.c more the space the more the time it takes to read and write and eventually the performance decreases. It also depends on what type of sdcard you are using, like class4, class 5 and so on.......

I had 1GB but wasn't enough 2GB will have a lot of problems, 1,4-1,5GB is max I recommend you for insertcoin.. I don't have any problems , 1.43GB ext

Sry for my noobility.. but why is that?
I mean.. flash memory allows random access, so why does it decreases r/w speed?

Thanks for your reply..
Could you point out what are the problems with 2GB ext?
And why do they happen?
Thanks !

I don't know why but Insertcoin became laggy as hell, never thought a class 6 16GB msd from Kingston could be the problem, but when i partioned it again i did just a little bit more than I had on my 8GB 1,3GB< and it helped a lot, Insertcoin is now working flawless.
Also another thing, idk if that's what they mean with sd card corruption but i could not move (almost) any files to my sd anymore since 2GB Ext. Got the whole time an error from windows, But why idk You should ask an expert I just don't recommend it

Ok, here is some geek talk!
EXT is really really slow! Why, becose its on your SD card, most SD cards used in phones are Class 2 cards, they have a read/write speed of 2MBs....
Your phones internal RAM/ROM have read speeds upto 1500MB/S and write speeds of about 500MB/S (depending on what type of chips used, PC RAM is much faster)
As you can see, there is a bit of a speed difference, even a Class 10 card is slow at 10MB/s
Also the SD card speeds are restricted by default, so if you are running a Class 2 card i would say you get about 1MB/s Read/Write speed (unless you use a SD card booster)
So the bigger the EXT, the slower the software is because it will take longer to read all the information, at 2GB of EXT (2048MB) takes the phone a long time to read going at less then 2MB/S on a class 2 card

Which to choose Apps2Sd or Data2Sd

Hi,
I have two partition 14 gb Fat32 and 2 gb Ext4 and I want that all installation goes on ext4 (without using internal strorage) so in this case what should I choose Apps2Sd Or Data2Sd?
thanks.

I wouldn't bother with data2sd unless I had a card of class 6 or higher.

I very much agree Class 6+ to get the benefit

Well you would want to choose data2sd, if you want as much to be on the sd-card as possible, however it is usually quite a lot slower than using internal, and there is no reason to leave internal completely empty.
Also you can't run everything from the sd-card. The system-partition will still be on internal as well as boot and so on.

Thank you mortenmhp,
I have sd-card of class 10, will still be a lot slower than internal?
thanks.

I use class 4 and have done from day one with droidzone's roms and it runs great.

I use a class 10 8GB card, and use Apps2sd. Dont really feel the need to use Data2sd.
Ive got alot of apps and still got some memory left so its all cool

Well it might not be too slow, but only do it, if you need the space, in which case it's a good solution.
But the more you move to the slower memory the more time will be spend accessing it.
But I'll encourage you to try it out for your self, as it's very individually(just make a nandroid backup and try different rom solutions) personally with my sd-card there is no way i'd use it for everyday use(flashed it a few times, and always got a slow and lagging system), while other people seem to have it working fine

Ok I will try,
Thank you mortenmhp...

Your question should be which do i need?
People rarely 'need' data2sd - apps2sd is 'usually' enough!

thanks for the infos

how do you know what class your sd card is?

there is a figure 2 or 4 or 6 or 10 in a circle printed on the sd card or you can install sd tools from market to benckmark it ( 2 means 2 mb/s , 4 means 4 mb/s,... aso )

i'd say go for apps2sd then if you need data go for that after

I now use data2sd with MIUI rom and a class 6 samsung sd card £16 from play.com
I would defo recommend this card, I didn't think from class4 to class6 would be that much difference I was wrong. I can now record videos without a single lag, phone is easy 10x faster and smooth, also MIUI is superb rom

Hi,
Most of the times a class 6 or 10 is much "slower" than a good
class 4 like the sandisk mobile ultra of 4Gb (The one of 8 Gb is slow !!).
The problem is that te typical test of writing/reading to/from a single file doesn't guarantee the behaviour of the card when used intensively.
When many files are involved, things change dramatically and a good memory controller is a must, and many of the class 6 /10
don't have one.

[Q] swap partition on eeprom

Can I use a part of the 1.5gb of rom in the desire z/ G2 to make a swap partition?!
It's dangerous to the eeprom life?
Performance would be much better than microSD I think..

As far as I know such a thing does not exist, though like you suggested it may be dangerous due to data corruption (though if properly partitioned you can fix it)
On the other hand using microSD for swap has been nothing but good for me, it has significantly improved speed, cause it is only a couple hundred Mbs of data on the swap partition so it can transfer quickly and smoothly, also it's only used when absolutely necessary.
What class microSD do you have?

I have class 6 microSD, but I think it's fake (trasfering speed is 2 - 3 mbps).
I think that the most important propriety for a good swap is the access time.. but the problem is that I can't find a site where I can see the access time of microSD tested by someone.
I want to buy a 32gb microSD class 10 or class 6, but if I can't find the access time..
I find that mustang and samsung microSD class 10 are cheap..
BTW I would love to know if I can make the swap file in /data or in /temp.
Access time in ROM is a lot faster that in microSD.
I don't think that rom can be damaged by a lot of writing, so why I can't use that support for swap. It would not faster as RAM, but absolutely faster than microSD class 10.
PS: I tried to make swap file on microSD with swapper2 and cyanomod 7.1. I get an error on swapon.. does cyanomod kernel support swap!? Thanks

It should but for the life of me I have no idea why, I'm assuming you were just testing it out but if not, swap is NOT needed for most AOSP ROMs and could in fact slow down your phone and kill your battery.
Also swapper is not the most recommended way of doing it as if something gets corrupted there goes your whole SD Card.. :/ safer to make a partition on it.
As for speeds, the speed from the phone to the SD Card compared to the SD Card to the computer (through the phone/data cable) will vary significantly, and so will read/write times. For me through my phone I can read at around 15 Mb/s (class 10) and write at 3 Mb/s, but if I take it out and put it in a Micro SD Card converter then I can write at speeds of at least 10 Mb/s.
As for access time.. If I'm not mistaken, after RAM, SD storage is one of the fastest digital reading and writing in terms of access time. I have noticed no discrepancies in speed where it would have to read or write to my SD Card's swap so I think that'll be okay.
As for finding out if the ROM can be used... Quite frankly, not a clue, but I would tread lightly there if you want to start experimenting

i am thinking about the same question... Maybe it 's to be safe to use your sd card and make a swap partition. However i am on miui which doesn't require a swap so i don't have to use a swap partition. And the sense 3.5 and 3.0 are to slow and to heavy for me for the old desire z with a such amount of ram memory ..

[Q] Epand Internal Memory

My question is what app can i use to expand my Htc Wldfire S internal from 150mb to lets say 600mb. I have "m1ndh4x8r GB2.3.5|OCKernel|Stable|Apps2SD|DATA2SD|Premium Features[1/25/2012]" rom installed and tried data2sd but it lagged way too much. I had it 2.8gb Fat 32, 847mb Ext4 and 70.6mb linux swap.(could i adjust this to increase performance). I used a class 4 PNY 4gb card.
Any other apps that can do this that doesnt lag???
Thanks in advance

I don't think there's a way to expand the internal memory. Just use a microSD card with Link2SD and put all your apps into the microSD card. I'm also using a class 4 card and I feel that it works well enough. Think there was a fellow who was purchasing a class 10. That's crazy haha. I think the speed difference felt stops after a while.

Yes you can.Using data2sd i increased my internal memory to 687mb i think from 150mb. However it lagged the system so bad.

try sd-booster https://market.android.com/details?id=de.mehrmann.sdbooster and see it make some difference. I am using a class 4 16gb sd card without any lag.

[Q] galaxy note 2 N7100 compatible memory card?

This really should go in the Q&A forum, but ... Samsung makes microSD cards. If those aren't "compatible" I wouldn't know what else could be.
Actually just about any class 10 memory card will do.

Yeah pretty much any Microsd will work on the note2. Choose Samsung, SanDisk, Kingston, Adata etc

I recently bought a 64 gb class 10 san disk micro sd card...it says ...they are the fastest...but hey...i am over happy with it...just installed the ex2sdinternal memory script ...it simply swaps your memory...e.g...my internal memory is now 64 gb...and my sd memory is 16 gb ....nice?
Now i can install any big gameloft and ea games without worring about directory bind and there freezes and force closes...
I really advice you to buy a 64 gb...it is cheap..i bought it with a adapter for 55€..it should be 70-75 $ max.

Is class 10 really important ?
Speed class corresponds to the burst write speed, which is important for devices like high end cameras. Since I have a class 4 and have no problem filming in HD, I suppose it isn't a necessity for the Note2.
Maybe more important are the read speed and IOPS (for small files) but I don't know where to find these data.
