What the title says basically. I'm looking to replace the 4gb class 2 sdhc card that came with the phone and get a bigger and faster one.
Depending on what the maximum size for an EXT partition is (I've read 1gb, other places said 2gb) I will chose between an 8gb and a 16gb one.
Coupled with that I have another question. I read that DATA2SD ROMs are generally slower that A2SD+ ones. If you were to compare an A2SD+ ROM using a class 2 sdhc card to a DATA2SD ROM using a class 6 card, which would you say is the fatest, most responsive?
Cheers.

Usually, size should be 2gb at max, 1gb is the general.
2GB is the limit for any rom before it starts to get a little unstable. 1GB is what everyone mainly uses but I have seen people with 1.5GB
IIRC by the guide I followed when I partitioned my card a long ago, it was recommended to have an ext of up to 1,4Gb.
1GB is ideal for the SD EXT
I have used 1gb also. (EXT4 partition)

I would like to know what is the best out of these two,or should i use both

MTD still only uses whatever internal memory the phone has.
I myself have a Class 10 MicroSD and half of it is EXT lol.
I also have a class 10 16g. Also is it better to have a large ext cause i tried data2ext with a 512mb ext and it wasn't very good
I am using the custom MTD myself with CM roms. This combination works well for me and is pretty much no-fuss to deal with.
However, if I were using a rom with a much larger footprint, like the CR_Mod-2.13, I would almost certainly go the apps2ext route...
what do you guys mean by class 10?
class 2= 2MB per sec
class 6= 6MB
class 10=10MB
Its the transfer rate of your sd card.
I think it pretty much relies on what you have, I plan on getting a class 10 SD card and use both MTD and Data2ext. Though currently I simply have MTD and put the leftover /system memory into data for now. Class 6 or above SD cards are better for data2ext, otherwise you'll lag your phone badly. I use CM-7 with a bunch of stuff removed and added Genius button, so I have 130 allocated to /system currently. if you use a Sense rom using MTD is almost pointless because it uses the full standard allocation of /system memory. Data2ext would be optimal at this point. So it boils down to what you are/plan on using and what you plan on doing with data.
How big should the EXT3 partition be for data2ext.

Hello...
I have a SanDisk 4GB class 4 micro SD card that came with HTC desire. I installed one of those ROMs that support Data2SD, and it was fast without lagging (actually, super fast).
I bought a Kingston 8GB class 4 micro SD card to replace it with the SanDisk, and installed the same ROM, but I noticed an annoying lag during the normal use, as an example, just after booting to the home screen, when I enter Settings, it lags for like 5 seconds (that NEVER happened in the SanDisk 4GB card). It also lags on different application such as when launching the web browser (a pause for 7 seconds, and again, that didn't happen with SanDisk).
I bought another card, this time Imation 8GB class 4, but it gave me the same results as the Kingston!!
I did a test on the three cards using H2TESTW, the results are as follows:
SanDisk 4GB Class4 --> Write: 4.5 MB/s Read: 11.3 MB/s
Kingston 8GB Class4 --> Write: 4.4 MB/s Read: 18.3 MB/s
Imation 8GB Class4 --> Write: 4.5 MB/s Read: 18.5 MB/s
They all share the same speed in writing, but the Kingston and Imation are faster in reading! which confused me! They both have faster reading speed than the SanDisk BUT lag annoyingly during the normal use!
To be very clear, I tried the Imation card with a ROM supporting App2SD not Data2SD, and it ran smoothly with no lags, but once Data2SD is there, it starts lagging! (I know that Data2SD ROMs are slower than App2SD, but I swear, the Data2SD on SanDisk is FASTER than App2SD on Kingston or Imation).
One more thing, I tried various partitioning for the 8GB cards, with and without swap (swap was always 32M) but with no luck to improve the performance.
If anyone has a logical explanation for this case please let me know, and if there is a certain fix for that (I don't know if increasing the swap size for the 8GB due to their higher capacity would help) please share it here.
Thank you.
Are you by any chance using starburst? Try the newer xe and we scripts on the beta section.they should eliminate lags for slower cards
Swyped with my Starburst based Desire. Forgive any typos!

Thanks for your reply.
But it seems that the both of the 8GB cards that I have are faster than the 4GB card, then why are they slower in ROMs?!!!

Well, from what I understand, 4gb are faster in real life than 8gb, all proper tests show that, look up test charts in Google. I believe its because it takes more time to search for info over the larger space. I'm only speculating on that, as I don't know this for sure.

Well, that is what I thought of too, take -for example- 500GB hard disk drive, it will take much time to scan than a 120 GB drive, which is logic.
I will do more research on this thing and will post back.
Thanks.
ok,
so i bought an 8gb kingston micro sd card, tested it with hw id and got 8mb/s write speed,
partitioned the card using gparted (allign to mib) with a 1gb ext and the remainder as fat32,
used sd card tester on my desire and it says write speed is 3mb/s or under,
so i tried sd speed increase set to 2048kb, atill 3mb/s or less write speed,
any ideas?
He,
I got also a Kingston 8GB Class 10 in my Desire (1GB Ext4 & Rest Fat32).
My speeds just for your ref.: 6.2MB/s writing, 16.4 MB/s reading with 2048kb.
I tried nearly every setting in SD speed increase but could not get over 6.x MB/s
---edit
just saw that we are running the same ROM (same kernel). maybe its ROM related as I also not have full 10MB/s? or its the SD card?
well i reflashed the rom without repartitioning the card and now im getting 6mb/s write speed,
better but still not as good as when i test the cards speed on my pc,
im not that worried about improving read speeds, i was just hoping that the faster write speed would solve some of the video recording lag i am getting,
maybe the cards you guys bought is not genuine but a chineese replica. you know how many fakes ciculate in market.
I have class 4 Sandisk 16gb card and I get 5mb writing speed. 12mb reading...
if a class 10 card has 6mb then I would doubt either the Testing software or the genuineness of the card

but when i do a speedtest from my pc via a card reader i get 8mb/s when i test the same cards speed in my phone i get 6mb/s, where does the 2mb/s go?
Try formating the cards on a pc. Full format/ factory condition. Then insert them on a stock rom phone to test the speeds. It's the only way to check them and be 100% sure.

SD speed reports my pny 8gb class 10 as writing at 8mb/s and reading 28 MB/s.
I have a 1gb ext4 partition after a 6.5 gb odd fat32 partition. Currently running leedroid latest R5 HD Rom.

Did you try this tutorial?
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.
Hi,
my phone is quite "slow" because I must have INT2EXT (without +) because of data/data are too big when using INT2EXT+..
Currently I have quite old 2GB SD card and I would like to know if it will be better with Class 10 SD card 16 / 32 GB?
Do you think it will be much better or not as much to pay money for new SD card?
Thanks
I have ADATA Class 10 UHS-1 32GB card with 1GB INT2EXT4 partition and it is fast enough in my opinion. I don't remember but it seems to me that the speed of memory card is similar to the internal memory. Anyway phone runs great when apps uses less than half of second partition. If they needs more phone is getting a bit slower. I'm using CM 10.1
