SD Card Capicity

Can someone tell me the max capacity XDAII can take for SD card? Can I put either a 512 or 1G card in?
Thanks

Both is possible.
AFAIK there is no limit for SD-cards

FWIW, I'm using a 512MB Panasonic SD card and it seems to be OK.
HTH

since the sd card uses FAT16, I think that the limit would be something like 4GB.
but also I think that it should be possible to format a sdcard with multiple partitions.
just tried, under xp, it is also possible to format an sd card as fat32, the xda will read it too.
format DRIVELETTER: /fs:fat32
in that case the maximum size is 32GB.

Thanks!!!!!! All very useful information... Didn't know that you could specify the format.

At the moment, I find 256mb the most economical, although 512mb are only just slightly more expensive than two 256 cards. 1gb cards though are nearly 3 times the cost of 512 ones.
They are small and easily swapped over, and you can fit a lot on a 256 mb card. I can't see any point in buying a 1gb card until the price drops substantially.

That what I thought initially, but because I could get this 1GB card at a really cheap price, well less than £100 each ;-)

Where can u get a 1gb SD card for less than £100 - pls provide a link

Chances of a Hero build (No swap)

Hi....
I just wanted to check what are the chances that someone makes a Hero rom that doesnt require the swapping crap which kills SD Cards eventually and doesnt actually make the rom still run as smooth as normal builds like JF 1.51 etc..
So What are the chances that someone can make a normal Hero rom that you just install and start using right away. Without any swap crap

No one is forcing you to use swap. You can load a hero rom without using swap.

^^ Like he said you don't have to use swap. It will be hella slow though and that is NEVER going to change because your G1 has 192mb RAM and the Hero has 288mb, and the Rosie/Hero stuff was designed to run on that amount of RAM. That is all there is to it and it will always be like that.

"eventually"
Your card should have at least a years warranty anyway by which time prices, sizes and performance will have moved on.
I just unearthed an old 64MB memory stick duo from a few years back, 4 times the size and 1/128 the capacity of my 8GB microSD which was 99p cheaper.

Thanks man, that was pretty much the answer I was looking for !! I didnt understand why Hero required the use of swapper. But it makes sense now.
But thats not good news for me !! Coz I really liked the Hero build , its a joy to use!. But with the use of swapping I dont find it very enjoyable, its still lags when you start running various applications.
Anyway thanks for the replies guys........appreciate it !.

What size swap did you try? You can really go as high as you would like, although much over 96mb is overkill I imagine. Also it makes a huuuuuuge difference when you change the swappiness to 80 or 100.

I'm pretty sure your SD card is going to last more than 2 years despite having a swap partition. You make it seem like a swap partition will kill your SD card in months.

With a swap, your card will still last for a couple years. Cards at $10, so who the hell really cares anyways? Even if it lasted 6 months, big deal.
I'm not sure what settings you are running with, but you need to turn compcache and backing swap off, and ONLY use linux swap, 96mb with 80 swappiness. The rom is extremely fast, for me, just like the 1.5's. I was pretty much crazy shocked by just how fast hero is with a good swap running.
I use it daily wth exchange for work, with several widgets, i use the weather, the galleries, contacts with all the facebook integration, never a slowdown.

I have a 104Mb Swap partition, 1.6Gb ext3 partition.
I had set my swappiness to 80. But for example just trying to turn wifi tethering ON, completely killed my phone , it got soo slow that ended up freezing.
and Yes, i am running only Linux swap no comcache.
From your replies, I can see something is possibly wrong with setup.
Could it be due to the fact that my SD is a class 2 ?

Your swap size and ext3 is to big, thats prolly why you were having issues.

well, what do you recommend then ?

Swap size should be at 32 or 64. Some have gone higher but not recommended. And ext partitions shouldn't be more than about a gig.

Is 2gb sd card enough for a A2SD?

I was just wondering would the sd card that the hero comes with (2gb) be worth it to parition it for A2SD?

thats what im using have about 40 something apps on it

Absolutely worth it. I was getting low space warnings without a2sd, but I'm running just fine now.
If you're one who loads a lot of music and video on your phone, you'll probably want to upgrade to a larger card anyway, but if you don't fill it up with that sort of thing, then you can install a2sd and still have plenty of space left for other things.

question: doesent a2sd fry your sd card overtime?

It's not so much the size you should be worried about, it's the speed. You want a class 4 or better, preferably class 6, 8 or 10.

Partition Size Recommendation - 8GB SD Card

I have searched, googled, etc, but I can not found a recommendation on partition size, for a 8GB SD, on swap, ext2.
Does a "recommended" exists?
Today I have 128 SWAP, and 896 Ext2.

What class sdcard? For a class 4/6 that seems pretty good it really depends on how many apps you have and how much multitasking you want to get done.

I basically want my phone to respond as fast as possible, to whatever i'm trying to do. So i do not mind using more, if needed.
Is not like I would be loading it with 7GB of music or videos.
It should be class 4, do not think it is 6.

Also depends on what rom you running. With Cyanogens 2.1 build its better that you don't use swap. So there's several factors to think about.

I'm currently using 4.x.

128mb swap is too big, fool! Drop it like it's hot.

You mean like it is going to do harm? or like it is a waste? you mean to totally drop it, or to drop it to 96, or 64 or 32?

Who let the dogs out?
Too big of swap size slows the phone. Many apps will be kept running in the background due to this. That's a bad thing. Go with 32 or 64 swap. And for an ext size, 528mb is sufficient. Unless, you have more than 200+ apps, which I doubt.
IMO, I avoid swap and use compcache instead. Swap slows down after a week. Only use swap if you like running a ton of Widgets and background apps.

Memory card swap partition.

Now if I increase the swap partition on memory by lets say 256 MB ,will I get better performance?
So what I am trying to say is bigger swap =better perf0ormance.

Bigger swap partions does not mean batter performance... at all!
Remember that your phones RAM can be read and written to faster than your SD card, the only reason we use swap is so we can get a bit extra space when we need it. What your really don't want is your phone off-loading tons of data to swap, as the read/write speed of your card will become the bottleneck, instead of the amount of storage available.
Stick with a small partition, no larger than 64MB and don't make the swappiness value too high either.
It's just there as an overflow, swap is in no way a substitute to real RAM

I am currently using cyanogens latest rom.
So I should have a 512mb extra with a 64mb swap?

Personally I don't use either, as I only have a class 2 sdcard and I don't see how anyone could need more than 300mb for apps, but whatever.
Ext is your choice and yeah, anything from 32mb to 64mb for swap (assuming swwap is automatically enabled, as I said I don't use it).
