Is my stock SD card the problem?

I've verified that my swapfile is in use. It is set to 32mb right now. I'm using the stock card. When I use alot of apps I'm still seeing the htc screen sometimes. I just ordered a ultimate class 6 133x 20mb/s card. Will this help the problem? And what are your thoughts on pushing it to slightly higher than 32mb? Even with a blazing fast sd card??

Yes, your stock SD card will be a bottleneck in using swapper and Apps2SD for that matter. But, you really should partition it w/ 3 partitions (FAT32, ext2/3, linux-swap, in that order). The linux-swap partition works worlds better than the swapper. 32MB is optimal, any higher will not speed it up, more likely it will make it slower. Set up those 3 partitions, and flash the new JACHero2.7.3 and you'll amazed at the difference. There's a new swap-type thing going on w/ compcache, but that hasn't been incorporated into the builds yet, so just stick with linux-swap for now.
If you wanna know how to set up the 3 partitions, follow the instructions from the JACHero2.7.3 thread in the development thread. Good luck

You sure its compatible with the g1? 20mb/s? Wow. You won't have anything to worry about if its that fast....Never heard of a micro sdhc card that quick lol. Mind shooting a link on your OP? Thanks

Killer SD card on its way to my house omg i can't wait!!

[Q] Which lag fix uses the EXTERNAL SD card?

[Q] Which lag fix uses the EXTERNAL SD card?
with so many choices for lag fixes
i kinda lost track which project was the one that was doing the symlink and copying data to the EXTERNAL SD card.
External SD cards can easily be replaced if dead
Internal SD card is a pain in the back when it dies
at the same time this is a perfect scenario for SD cards performance test for Class 2, Class 4, Class 6+ speed tests
Class 8 and Class 10 are not widely available yet for microSD format.
if some one remember the Dev topic please link it
thanks

no body is using this lag fix?

Can't seem to recall which one that is but here's a bump for ya.
Must have been a while ago huh....

not anymore, seems like no one cares that the lag fixes writes to the internal SD instead of the external SD

I remember using it before. it's called mimocan or something. went through a lot of trouble to format my card into ext4.

There was something on modacco about it I recall... maybe Paul did it

yeah that! paul madacco!

I can't recall the name either but in the last 2 months we've moved on from external fixes as it was annoying to create the external partition, Also speed wise it wasn't a good fix.

There is the old mimocan lag fix:

and also this new attempt using JFS FS on the external card:
http://forum.xda-developers.com/showthread.php?t=812836
Modaco lag-fix was using the oneNAND fast memory. But it is internal and also is "limited" in size. ~130MB available only.

thanks i am using the internal modacco fix i guess. no problems with it.. but again limited in size although i have about 100 apps installed and still have 78 meg free. so probably could go over 200 as long as you dont have huge apps like certain games..
it seems like it is a lot less hard on the internal sd.. and maybe that is why it makes more sense to use this or one that does use the external sd for the i9000m specificially which is touchy with the internal sd card.

that's exactly my goal
since it's a known issue, it'll be better off playing with External SD, as they can be easily replaced if dead
you can also keep upgrading to newer faster models of SD cards

[Q] Booting HC off of an SD card

So I just bought a nook color and am trying to run the Honeycomb port off of an SD card, 8 gig, class 4. Upon turning on the nook it gets as far as the second flash followed by the "ANDROID" in the top left corner. I've tried reburning the img on the card, but the same problem results. Any advice on how to get past this? Thanks!

check your hc image against the md5 hash.

I believe that some SD cards just don't work with HC. I tried a few times on mine and never got it to work.

I think there is another post that discusses the cards that work, the ones that do not, and the ones that work for some folks and do not for others. Due to this information, I purchased an 8 Gig Class 6 Transcend (from Newegg) that works well with Honeycomb for me.

try a class 2 or class4 sandisk, they will perform well. the random read/write times on these cards is usually really good.

worked for me!!

Thanks for the help all! I was able to get Honeycomb working off of this thread:
http://forum.xda-developers.com/showthread.php?t=1045018
However, it contains updates in a zip file that are meant to be placed in a partitioned section of the SD card; I haven't been able to figure out how to place those files in other than the main partition. Is there an easy fix that I'm missing somehow? Thanks!

What's going on?!! HELP!

Hey guys. I'm pretty new at this rooting on NC. But I got everything to work on my Nook for such as like having CM7.1 On my SD card and stuff like that. I have the default kernel on there running on 1.1 Ghz, but it seems like everything keeps crashing. I can't do anything without it screwing up on me. I have most updated stuff but nothing seems to work. I have a 16Gb C10 working so I believe is that but I just don't know...
...Anyone please have any advice or suggestion on like CPU settings or anything?
Thanks!

If that 16 GB class 10 is the card you're using... it is most likely your culprit. Sandisk class 2 or 4 are by far the best cards for running android os' from.
The reason is that class 10 cards have much higher sustained thru-put... but the android os' (especially) utilize much more small read/write cycles.. which is where the class 2 and 4's exceed the performance of class 10 cards.

So what should I do afterwards? Once I buy a class 4 should I just reflash on the SD with CM7 and start over? Or should I back up from this one and flash it on the card?
I appreciate the help

Always, recommending doing a fresh installation.
It won't take long.

So I leave the Nook as is? Just flash the new image?

Yes. The install and run on SD method does not touch your standard Nook install.
Just repeat the install method on your new card. If you had put a lot of apps on and organised your desktop screens then you could back those up (Titanium for the apps and ADW settings back up for the desktop), save the folders away first then restore once you had the new card working.
One of the benefits of the emmc installation method is that it makes updates, backups and restores a bit easier as the SD card is just user memory.

any way to test write/read speed of internal nand?

is there any app or anything that could do that?

there is some thing called sd card test search on market ..i hav used once
