Can we replicate this on the Captivate? I've been playing around with my new Epic for a few days and it is AMAZINGLY fast. This is supposed to be the lag fix that Sammy employed on the Epic.

I knew it was just a matter of time until Samsung took action against the lag problem. I mean they wouldn't want their big, bad, and fast galaxy s line slowed to a screeching halt because of lag issues. I wouldn't be surprised if we see this in an update in the near future. With Samsungs track recored though they might end up waiting for Froyo to emplement it.

We have a nand lag fix already right? Wouldn't this give the same results? I thought the ext 2 internal storage lag fix was faster the the nand fix.

I'm no dev but I think this is the same thing that's already been implemented by the community (for that matter, Samsung probably got the fix from the community )

From what most have gathered, samsung didn't fix the lag, they used different hardware that is faster. That will do no good for captivate and vibrant users.

What the heck?
A) It uses the same hardware that matters anyway (granted LED, keyboard, etc is different).
B) Someone pulled the init.rc and proved what the OP is saying
C) You don't know what you're talking about

is there a good reference for the mapping of /dev/? or the whole file system in general? I went to see if busybox had a symlink for bash and much to my surprise there was no /bin. I'm new to android but a long time linux user and the differences are becoming readily apparent.

I wouldn't go as far to say that. Everything is the same internally other than how the file system is setup, and in this case they are using the NAND (I believe).

From Boygeniusreport:
"We’re assuming the phone uses NAND Flash as the internal memory medium. On the Captivate if you navigate to Settings >SD Card and phones storage you see “External SD Card” and “Internal SD Card” listed. On the EPIC you see “External SD Card” and “Internal Phone storage.” We’ve reached out to Sprint for clarification and will update this article if they respond with a definitive answer."

The Epic is missing the 16gb internal SD card... the SD card that Samsung has split into 2GB for apps and 14GB for /sdcard for the rest of the US Galaxy S devices (no idea how the EU phones are set up). As a result, it has far less space for apps, but it more than makes up for it in speed.

About the only thing that I think Samsung can do to improve speed on the rest of the Galaxy S phones is to either work like hell to come up with a better driver for the internal SD card, or to accept a massive limitation in app space and build in the original lag fix.

I'm hoping it's just a driver issue... when copying a 1GB file to and from my /sdcard using the USB mass storage mode, I sometimes see 10+ megs per second, and sometimes see >1 meg per second. This is with my phone sitting idle, nothing else going on at all (except for OS Monitor, so I can see what's going on). That leads me to believe that it's either a driver problem or the internal SD card is the world's crappiest. Seeing as everything else on the phone is very nice hardware, and seeing how the GPS and compass drivers have issues as well, I'm kinda (and maybe foolishly) thinking that it's probably a driver issue. We'll see.
