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.
http://forum.xda-developers.com/showthread.php?t=737829&highlight=nand+lag+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."

same hardware, different software...just minor things different
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.
It almost certainly is a driver issue. Formatting the internal SD with another filesystem provides a large boost in I/O performance. It's not as large as with the loopback hacks, which probably result in both subsystems buffering data, but it's enough to make using the device much more pleasant.

on the Captivate, if you scroll down farther, past Internal and Externa SD Card, you will also see "Internal Phone Storage".

The Captivate has both, as you can see quite clearly in the shell by using the mount command. Most if the partitions are segments of the NAND, using /dev/block/stlXX devices, but /data is /dev/block/mmcblk0p2, the second partition of the internal SD card. All are Samsung's proprietary RFS filesystem, which appears to perform poorly on the SD.

pardon my ignorance, as i truly am ignorant in the subject, but how are logical names proof of physical hardware? could Samsung not have partitioned a NAND chip with different mount points and call them whatever they want? from the tear down pics, it seems that there would be no room for an internal SD card on the PCB. also, from reading around, it seems that all Galaxy S phones are pretty much the same hardware-wise, is this not true for the Captivate version?
again, i don't mean to come off antagonistic. i'm just searching for knowledge.
I just wish everyone would quit calling the system memory an "Internal SD card". There is no such thing. Samsung gave it this stupid name so the simpleton's of the world would realize it was data storage.
SD - Secure Digital is a form factor design. The phone has different kinds of flash memory and no one has yet to determine if the 14GB "internal SD" is a seperate chip from the total 16GB of internal storage.
Comparing this "Internal SD" to a real SD card is just dumb. An SD card is removable, of a certain physical size, has a write protection, and supports built in DRM - part of what Secure Digital means.
I am speculating too, but until someone can pinpoint the chips used on the captivate, we don't really know what this internal SD is made of.

I agree - SD is just NAND with DRM and some other features. I think Samsung just calls it this to separate internal OS/Application storage from user addressable storage. I would be there is one 16GB NAND chip as I have never heard of a 14GB chip. I bet they just partitioned the 16GB chip in different ways, but for some reason gave the 14GB chunk a slower FS partition by mistake.

Ah, good to know then. Thanks!
It is not only a logical name. While there may not be a removable card in a slot, the name suggests, and information in sysfs agrees, that the "internal SD" is accessed via an sd/mmc host controller. This means that many details about the flash are being hidden from the OS - it doesn't know what the erase block size of the flash is, it only sees a device with a certain number of blocks and a partition table at the beginning. Block remapping and wear levelling are hidden, which is why we can't use any of the linux filesystems for MTD devices. And for some reason, I'm not sure why, RFS performs much worse on an mmc device, or at least on this one, than it does on the OneNAND partitions. That it should matter seems a bit odd, as they are both block devices, but perhaps the OneNAND driver exposes some other information or interfaces via ioctl calls that are not present on the mmc device.
It is certainly possible for a filesystem to perform better on the internal SD than RFS does - this is easily demonstrated by formatting it with ext4 or nilfs2, and is also suggested by the improvement in lag that some seem to see with the leaked firmwares. In the future we may not care about alternate filesystems, because we get an rfs module that performs better on the internal sd.

sounds reasonable, thanks. but getting down to it, is it not at all possible that the internal "memory" is a physical NAND chip, albeit partitioned and interpreted logically however Samsung saw fit?
this may seem like a pointless debate, but perhaps if the community knew it was NAND for a fact, they could rewrite this or that to make things faster/better/etc..
here's a link that revers to the internal memory as NAND. not the source i'm looking for, but it's something:

here's another spec sheet referencing NAND:

It was like that even before I rooted. I noticed it but it didnt really phase me until recently. All my music/pics are on my card. I had to jump on HTCs site just to confirm that I was supposed to have 8gb and wasnt remembering it wrong..lol. But any insite to this would be helpful. Again thanks in advance for any help
I do believe it has 8gb but 3.2 gb of it is partitioned...
Sent from my ADR6400L using XDA App
I believe HTC partitioned it in a way that only 4GB of the 8GB eMMC is usable (the other 4GB is out of reach, it seems), and within that 4GB, you only get about 2.5GB or so user space, with the others reserved for the system.
And since it's one time only, we cannot reverse the effects of that partition.
Ya it is pretty ubsurd that you lose about 70% of your internal memory.
I do think it was smart to partition space for the system in excess of what is required, just to keep it stable.
Also, I imagine HTC had to put aside a hefty chunk of memory for HTC SENCE.
However, that seemed like way too much when I first encountered the problem myself.
So I e-mailed HTC who told me that the thunderbolt only has a 4GB eMMC under it's hood. That would make the numbers make sense because then the formatted space would be about 3.8 Gbs and that would mean only 1 gb was taken for the system.
why doesn't HTC or Verizon address the misprint claiming it has 8GB eMMC ?
that is a quesiton I can't answer.

This same question came up when the G2 came out and everyone was rasing holy hell about it.
Physically there is 8gb in the phone. However, if I remember correctly (you may need to Google it), the explaination was that because of the way Android uses memory, it is unable to use the extra memory properly. The only analogy that makes sense to me was like how in Windows, unless you set up your hard drive as NTFS, instead of FAT, you were unable to format a partition over 10mb.
Samsung got around it by showing the "extra" memory as another "partition" of sorts so the memory shows available.
So to make a long story short, the memory is there, but system limitations, along with some of the memory being used as backup cause you to only see the 4gbs.
At least that is the way I understand it. Maybe someone else may know more about it and can explain it better.
It has an 8G flash:
Code:
# fdisk -l /dev/block/mmcblk0
fdisk -l /dev/block/mmcblk0
Warning: deleting partitions after 60
Disk /dev/block/mmcblk0: 4487 MB, 4487905280 bytes
There's over 4G available as a flash device to the OS. I suspect the rest is where the radio code is stored, and is not visible to the Linux side.
Ok so I just got a SGS4G I had a Vibrant 3g and since the 4g didn't come with an sd card i used my original one from the 3g as we all know that had Avatar on it. I don't care for either movie and I knew Avatar wouldn't work on the 4g so I decided to format it through the phone and now I only have 2gb of memory. But the original sd card seems to be partitioned into 2, one for the movie and the other for files. I can only access the part the movie was on(2gb), so back to my problem how do I retrieve the extra storage space. When in the phone the computer also only detects one part(2gb) instead of the usual 2 drives
Just go to tmobile and ask for a different one

Have you actually had any luck with that at a T-mobile store, its worth a try but just wondering why i cant access the rest of the storage space
so I just found out that in the 4g inception is in the same root menu as all items stored on the sd card, but on the 3g the avatar movie is in a separate partition. I formated it and now one partition is compleatly gone and i can only access the other which contains only 2gb instead of the 8gb it has

I thought it supported up to 32gigs...
Anyways i while back i got a class 10 16gb Amazonbasics micro sd card for $26-speed tests on my phone proved it was actually class 10 too! when i recieved it i didnt formatit at all, i just did what the op said, i took out battery took out preloaded 2gig card pluged in new 16 gig card and it showed up right away
You say its showing you have about a gig on external right? That neans it has to be detecting something or its just stuck on the old one since even tho its gone...heres what i would do:
1) go to seetings>sd card and phone storage>format usb storage
2) reboot
If that fails then:
3) if you have a rom installed then reflash
4) last resort odin back to stock
Hope that helps and if it doesnt see if the amazon basic sd card i got is still on sale if it is i highly suggest getting it!

I am on MIUI so I go to SDcard and hit format? because that is the only Format option I know of. Also since it is backwards in the about phone ( Internal Storage is actually Sdcard and Sdcard is actually Internal) I don't want to accidentally format my phone.
Hmm..not on miui but for me i actually have to unmount sdcard then i can format...i know i said something different earlier
So yah if you have the option to unmount one of them then thats the one you want to format and you may need to unmount to format it
If you cant format (which ive never needed to do only done it to start clean) then there might be something wrong with your rom

So what I've seen elsewhere about other androids that don't support 64gb being able to work with 64gb (essentially ~59gb at formatting) doesn't apply as well to the Infuse?

Like i said earlier the phone is detecting something otherwise it would say no sdcard inserted-problem is its stuck on detecting the old sdcard...try turning your phone on without the sdcard and see what it says because im guessing its going to still say 1.87gb left if it does then im sorry but you should probably try reflashing your rom, if that doesnt work then try odin back to stock i know its not much help but its all i can think of
If it says no sdcard inserted without the sdcard in than you probably have a defective sdcard. If thats the case go exchange it for a new one wherever you bought it at

What's the purpose of Adoptable Storage? Does it basically turn the memory into one giant "partition?"
Sent from my SM-G935T using Tapatalk
I tried this and never got it to work. Kept showing 179:0 like it wasn't seeing my sd card.
I have a 128gb Lexar high speed MicroSD i picked up from Amazon and i've had zero slow downs. I believe the SD Transfer rate is around 95mb/s so there should be zero issues with it. I did a 50/50 partition according to the guide.
Should note though - some guy says in the comments on MoDaCo's site that you can just download a terminal app and enter the commands directly. well, he's not correct. You can if you have root. Since i actually use Samsung Pay, i am not going to root this device. You need to use ADB as it states clearly in the instructions. That will work fine.
Just FYI.
Amended to say I tried just skipping to the next step, regardless of the 0, and it worked And no slow down so far
I got the same thing. Use a comma instead of the colon.

I'm frankly afraid to do that. When I ordered the phone I also ponied up for a Lexar 1800x (u3/UHS-II) 64GB card. It's expensive and really fast. It tests out in the supplied usb 3 reader on my windows pc at 175+ MB/s write speeds and somewhere in the 90's on read using winsat.
In the phone read is 68 write is 54, which I guess is telling me the sd card reader in this phone is very slow?
The internal memory tests out at 275/93
When I move apps to the sd card the boot process of the phone takes several minutes with multiple errors that all seem to be related to the incredibly slow read speeds of the sd reader. Once it's booted up it's good enough, but I don't know how adoptable storage would affect this. I guess this is probably why it's not enabled. I want to wring the necks of everyone that complained loudly that slow ad-on storage was somehow better than fast built in storage in the 6. I really would have preferred a usb c port and 128GB of internal ram to the sd reader.
Maybe someone can tell me if there's something I can do to speed the card up? Are other people seeing these kind of slow card speeds in test apps? I'm using Disk Speed Test.
I'm tempted to do this too, I just got a Samsung 128GB Pro+ which should be no problem, I might try it once I ran out of space (SOON).
Alright, I finally got a chance to format my Samsung EVO 32GB card. I followed the instruction from my original post. The only hiccup is that my SD card showed as 179,0 but I don't have any issue formating with that info.
I restarted my phone several times and I don't notice any slow down, boot issues, or slower boot up time. I haven't bother to retest my system, but I'm pretty sure the phone is slower with adaptive storage (and my card isn't the fastest out there). As for real world experience-wise, I don't feel the phone is any slower than before.
The key thing is that once you formatted SD card, make sure you go to Settings > Storage > SD card > More. Select Migrate your data. That will move your photos, music, sounds...etc to your external storage right away. Oh, and it seems like the default app storage is still internal memory. So, I have to move the app after any new app install.
Now, there are 2 issues/concerns I have. First, the total internal/external capacity that being displayed by the system is kinda of funky. I don't think the info is correct. And when you mount your phone to Windows/Mac, the external storage isn't displayed while the total storage isn't accurate either.
Second, I understand that I can't move pre-installed apps/system apps to external storage. But I'm not sure why certain user installed apps can't be move to external storage.

There appears to be an issue with your read/write speeds. Here's my test on the S7 Edge from T-Mobile. This is a Samsung 32GB card. But notice that even your built in storage is considerably slower...

OK, so one important point that "Recent Test" is not of your SD card it's of the virtual sd card that is built into the phone. So it's a test of the internal memory. To test the sd card, you have to click that red button, not the blue one. The Yellow and Green buttons both do the internal memory, just using different folder paths to the same physical storage space.
As to the faster write speeds, the tests will vary depending on what the phone is up to, and I think my result is probably slower because your storage has about 5 more gigs free. This is one of the things that made me slap my head when they announced 32 GB max in the US. As storage fills up, it slows down. 32 may be enough to squeeze most apps into, but having the ability to leave another 32 free makes things way more efficient.

I have a 128gb Lexar high speed MicroSD i picked up from Amazon and i've had zero slow downs. I believe the SD Transfer rate is around 95mb/s so there should be zero issues with it. I did a 50/50 partition according to the guide.
Should note though - some guy says in the comments on MoDaCo's site that you can just download a terminal app and enter the commands directly. well, he's not correct. You can if you have root. Since i actually use Samsung Pay, i am not going to root this device. You need to use ADB as it states clearly in the instructions. That will work fine.
Just FYI.

Have you tested the card speed inside the phone vs the max rating?
Here is mine. My SD card is the 200gb one that came with the LG V10.
