Samsung ships first 3D vertical NAND flash, defies memory scaling limits

The main challenge in producing higher-capacity flash storage is one of scale -- as density goes up, so does cell interference and the chances of a breakdown.

Samsung may have overcome that barrier (if temporarily) by mass-producing the first 3D vertical NAND memory, or V-NAND. Instead of putting memory cells on a conventional 2D plane, the company reworked its long-serving Charge Trap Flash technology to create a 3D cell structure with more breathing room. The result is flash that improves both reliability and speed at higher densities; Samsung claims that the new technology is 2-10X more reliable than its ancestors, and twice as quick at writing data. The initial V-NAND chip offers a 128-gigabit (16GB) capacity that we've seen before, but its underlying technique should scale quickly when a chip can include as many as 24 stacked cell layers. Although Samsung hasn't named the first devices with V-NAND inside, we won't be surprised if our next phone or SSD is particularly spacious.

official Samsung press release

I use the SanDisk Ultra 32 GB microSDHC Class 10. Once I bought one I never looked back. Absolutely zero lag when accessing the card, fast media scanning, I can't say enough about it.
[Android General] k1ngdomhearts:
Thx For Good Thread
[Android General] superdragonpt:
Ummm, Do you work for SanDisk ? :p

On-topic: Yeah That SD looks Great
[Android General] EEngineer:
Absolutely not.

It is. Used to be when I played music there was a noticeable delay before the music played. Now, zero delay. It's great for speeding up older mobile phones.

It's like with a laptop, put in a faster hard drive and you get a dramatic performance boost regardless of clock speed because for example Windows is very disk intensive. So spend a few dollars more on a Class 10 microSD and watch your mobile phone fly.
[Android General] Cactus47:
suggestion?

I would like to buy a 32gb sd card for my HDC i9500 mtk6589 based.

What will be better: Samsung class 10 or sandisk class 6

The benchmark stats aren't very clear on which one should i go for...

Thanks
[Android General] NYLimited:
I don't know your device and don't have enough time to research at the moment. However, as far as i recall Sandisk does not make a class 6 card.

If you want to look at class 6 take a look at Samsung 32GB often available for about US$20.
[Android General] EEngineer:
From my tests, I can tell you the following:

The SanDisk Ultra (Class 10) is the fastest.

After that, a Transend Class 6 is only 10% slower than the Ultra, you'll save a few dollars and probably won't notice the difference.

A Kingston Class 4 is just as fast in reading as the above, but Kingstons have horrible write speeds which make them terrible for Androids.

You'll never know what you'll get with most Sandisk microSDs. I've had a SanDisk Class 2 test as fast as a Class 6. I had a SanDisk Class 6 read as fast as a Class 10 but had terrible write speeds.

I've never tested a Samsung microSD and I don't know anyone who uses them. I don't trust their quality.

If you do buy from a reseller, like eBay or Amazon market. make sure you test what you are getting as there are lots of counterfeits out there. Windows or Linux will tell you it's a 32G but in fact it's only a 16G and as it writes new data, older data falls off.

First use H2testw to test for the proper capacity. The function of H2testw is quite simple: It fills the chosen microSD with test data and then reads it back and verifies it. If it is a 32B card it will fill it with 32 1G files and then verify that they are still there. It also test for hardware defects.

You can use CrystalBenchMark to see how fast it is. Lastly, use the SDFormatter program to format - do NOT let Windows or Linux format a microSD card, it will mess it up. Using an incorrectly formatted microSD card in your phone will result in lost app settings and your ringtone getting reset.

You can google for any of these programs and download.

And don't forget to say THANKS!

Thank you guys...

I'd probably buy the samsung one since it costs less and i have little money.

Id anything goes wrong i can still return it back.

Will probably post some results here soon :)

Interesting stuff. I went ahead and bought the cheapest Class 10 SD card of any decently-known brand off eBay... Pretty disappointed with the performance and I guess this explains why.
[Android General] EEngineer:
You might have bought a counterfeit. Did you test it?

[Android General] Ryzaar:
Nope, straight in the bin! I've been using a 16GB Class 6 which is going much faster.

I assume it was counterfeit though, as it would often drop out when connected to the computer. I decided to chuck it out after a few attempts at transferring 5gb of music, where it'd constantly lose connection, and stop the copy process.
[Android General] EEngineer:
If you bought it off eBay you can file a complaint and get your money back.

If the device is rooted you would need to use some script to alter things. As I recall, Amarullz had such a script once though it has not been updated in some time as far as I know.

Hey guys i need help in my phone...I cant understand it...When my phone recieve a message from my carrier network to have a load...My memory card suddenly unmount itself....I was suprise on it when it 1st happen on me...After a while it back again and can be read by my file manager but on the 2nd time i recieve a message again it unmount again and thats the worst nightmare in my life that has happen my 32gb micro sd got corrupted and i haven't done any backup on my files....My file managers doest seem to read it even in my TWRP recovery mode....I was so down now...What should i do...???

By the way my phone is CM Flare that are popular here in my country it is also known as Karbon A9+......
[Android General] NYLimited:
You can try formatting it with SD Format but chances are you should try a new card.

SD Card limit

I have a rooted XPeria Ray with an unlocked bootloader, custom Kernel (LuPuS) and custom ROM (Super Jelly Bean based on 4.1.2).

I have a class 10 32gb SD card, and any more space would just be for fun :silly: (ie its enough). However, the following thought did occur to me, and was hoping maybe someone has tried it. :confused:

The phone is limited to a 32 GB SD card. I was wondering if I was to get a 64GB SD card and format it with a 32GB FAT32 partition (as limited by the phone) and have a second partition of 32GB in EXT4, if I would be able to mount and use this second partition? as well as the first of course.
[Android General] NYLimited:
What do you want to use it for? Yes, you can do a few things with it though you may need to modify some system files. For example, you could mount it as the /data partition if you were to modify init.rc , a pretty big one at that.

---

Any clod can have the facts, but having an opinion is an art.
[Android General] DiamondJohn:
Modifying System Files doesn't scare me, I have done quite a few manual mods on my droid as it is, including a swap partition (had to do it manually as Swapper2 did not return after boot :( ) and EXT4 partition for Link2SD (which all gave me the idea). I have run out of space on my 32GB SD card, as I record TV and transfer it to my phone to what on the way to work.

It would be good to not have to shuffle around files to fit below the 32GB. I also have a lot of MP3's and wouldn't mind taking all my photo's etc around with me, and any other files from my home PC :cowboy:

Now in the above, you imply I would be replacing an existing folder structure / mount (ie /data). I was hoping to actually mount it as an extra new independent mount. Seems to me if the above is possible, then that should be too, right? I understand it would be invisible to my PC (Win7, no UNIX), but I could always get virtual box installed with a UNIX shell I guess, or transfer between the FAT32 top the EXT4 :eek:.

The thing that really "caught my eye" is that while the FAT32 partition is not available till a minute or two after boot, the EXT4 partition appears to be available straight away. I have even linked my wallpaper and widgets onto this partition and its all up before I get past the boot animation (ie as soon as the phone is up), while the SD is still mounting. Or is this simply because the FAT32 partition is 30GB and the EXT4 is only 1GB? :confused: If I move an app to SD, I can't start it for some time after boot, but on the EXT4 (ie linked 2 SD), it will start as soon as I can get to it.
[Android General] rakijaman:
External partition as ext3 or ext4 is always faster than fat... nothing to worry about dude :) same happening to me
[Android General] NYLimited:
Well, I am not sure what exactly you would do with it but, yes, it can / has been done, even as a third partition. I was actually thinking of something a little different but in either case you can get some ideas and sample init code from

ph03n!x'

thread if interested.
[Android General] DiamondJohn:
Thanks for the link, but its not what I am trying to look into. The thread you pointed me to is about mounting the EXT4 as the /data partition. My question is if my phone, which supposedly only handles up to a 32GB SD card, could I have TWO 32GB partitions (one FAT32 & the other EXT4) on a single 64GB SD card? I would use a similar technique as in the linked thread to mount the extra 32GB partition. I just wonder whether my phone would be able to see both 32GB partitions, on the one 64GB SD card?

As for what I would do with it, "build it, they will come"... I also like to use my phone as a portable USB Drive when heading out to clients, and some files for work would fill 32GB fairly quickly. Also, I now have a swap partition, so do not expect my card to last forever, and my next phone would support 64GB's so would hope to get a 64GB card next, and possibly use it in my next phone. Just think a few years back, and the 32GB in my phone would of put many desktop PC's to shame. I remember my first computer having 16kb's of ram.

---------- Post added at 11:44 PM ---------- Previous post was at 11:10 PM ----------

Ahhh.. I found an explanation as to why the FAT32 partition takes time and the ext4 appears straight away.

While FAT32 is not journaled so every time it starts up, it needs to be checked. I'd post the link, but I cant as a noob with < 10 posts.
[Android General] NYLimited:
Actually, that thread shows where the partition is mounted and checked during the boot process. It does not have to be /data, it could simply be /extraordinary or any other name and, once checked and mounted it *should* be usable to functions in Android.

[Android General] Szczepanik:
ORD

I have ORD. I try each new NativeSD ROM using Windows Mobile and report results (usualy with AndroBench and AnTuTU benchmarks). The Devs appreciate feedback from clrcad haret users that their ROM works and nervous WM users need the encouragement. I use the latest ROM until the next one comes along. Using Titanium Backup it is easy to restore my apps and data. I do have my favourites and it is good to be able to switch from GB to ICS to JB. For example ICS to use Flash (BBC iPlayer) and my mobile as a wireless microphone for dictating to Dragon Naturally Speaking on my PC using WiFi.

Looks like somebody loves you - tyween just released new version of his TyphooN CyanogenMod 7.2.0.1 v3.8.9.

For HTC HD2 SanDisk Product Compatibility recommend memory microSDHC™ card 32 GB SDSDQ-032G-A11M which is Class 4. Even the manufacturer agrees with your choice.

Thanks for the update on ROM Toolbox. Any advice on how to interpret (and indeed share) the SD benchmarks?

Cheers

Tom
[Android General] NYLimited:
ORD... OK, you made me look! :silly:

Yes, I saw it and was tempted but I only have limited time to play as I need a working phone much of the time. So sad..

Thanks for the link - I took the liberty to move it up to post 1 (with credit).

As for the cards, yes, I still like that particular card although I have seen a number of people get good results with SDSDQY-032G-A11A and SDSDQY-064G-A11A Mobile Ultra cards. It should be noted that these are the slightly older versions of Mobile Ultra which are a little harder to find but likely more reliable for older devices, such as the HD2. Anyway, I just wanted to put it out here for those who must have the 'faster' cards. :angel:

The ROM Toolbox benchmarks are fairly simple. They just show you how long it takes to send X amount of data at different intervals. One handy use for them is to see how changing the value in your read-ahead buffer is speeding or slowing your SD Card. Again, I suspect that using the exact same method for benchmarking cards is more important than the numbers themselves. Even if the numbers are not 100% accurate their inaccuracy will be the same across cards when used across the board, offering a viable comparison of the cards.

As for sharing the results - there is no centralized place for them that I know of but I suspect several XDA threads might welcome benchmarks (especially if done the same way), including this one.
[Android General] NYLimited:
Mea culpa!!

Oh boy! I need to pay more attention.. My grateful thanks to ph03n!x for pointing out my significant error of using KB instead of MB in a couple of posts! While the posts were factual as to my device's current setup and performance the typos were embarrassing.

While talking about ph03n!x (who, as far as I know, started the DataOnExt idea!) you may want to look at some of his test results as well. Although my own experience does not parallel his findings I always recommended experimenting to find what works best on a given device. His test results are in a spreadsheet in

this post

.
[Android General] ph03n!x:
My test was playing temple run or ninjump- both involves constant texture reads from the /data, which in my case is in the ext partition, and minimize lags without overclocking or any other drastic mod...

Hi

When I choose my sandisk sdxc card in my phone with sd-tools, it says "no card infos available". Why is that? :confused: Using galaxy s3 with cm10.

Also I was using EaseUS Partition Master to format it to fat32 (was exfat). Was that bad? Should I have used SD Formatter?
[Android General] chase_me:
Hi...ny_limited

firstly appreciate your extensive data provided on micro sd cards and misc...

Im using kingston micro SDHC 8Gb class 4

1. Will the card support ext4 partition ..??? .i saw some were else in the forum dat it does not

In this case ... im asking I think ur the right person

2 .Btw what buffer size and cluster size do you suggest for above card?

3. Actually I ran into a prob..

I partitoned my 8gb sd card with mini partition tool

6.xx...gb as primary fat32 and 800mb as ext4 primary

now after using it for some time..now i wanted to do a fresh repartitioning

so i formatted the sd card using cwm recovery...

Now I inserted my sd card into the laptop sd card slot..(using adpater)

Now the mini partition tool only recognizes 6.5GB as primary fat32 but its not showing any 800 MB ext4 partition

So Im searchng howdo i get my the whole 7.xx GB memory back??

PS: Im dwnlding Easeus partition manager..to check if its detects ext4 partition on card.Will update as soon as im done with it.Do you have any suggestions for it??

Thanx a lot mate :good:
[Android General] NYLimited:
Are you saying that SD Tools does not see the card at all and will not run any of the tests on it? Or does it simply not know what make and model it is but it can run the benchmarks.

I have seen reports of SD Tools acting up on some SGS devices though I have no idea why. If it can run the read/write tests it may simply have a problem reading the new 64 GB card. I don't have either the card or the phone so cannot try it myself, sorry.

I have had good results with Minitool and, of course, SD Formatter. That does not suggest that AESUS creates problems - I simply don't know about it. I like Minitool's ability to create the ext4 partition as well but generally use SD Formatter first which will determine some of the oprimal choices for the card (such as cluster size).
