What NAND speeds are you guys/gal getting on your new S4?
Please post your version: Either Exynos or Snapdragon
I'm trying to decide on getting 16gb or 32 gb...
Can you run Android apps on microSD cards and do they work the same?
On my note 2, after I swap the int and Ext SD card, theres no notable difference in app per se, but there are hiccups in the OS which happens a couple of times a day.
On a separate note, Modern Combat 4, has a half second delay.

Hi guys,
I'm curious about the speed of the bundled microSDHC card. I just benchmarked it with SD Tools and consistently get around 6-8MB/s writes and around 17MB/s reads, and the label says Class 2 so it's performing way faster than rated (more like a Class 6). I'm running jt's CM7 Alpha 3 if that makes any difference.
I'd appreciate it if people would post benchmarks of their bundled cards or any other SD cards that they've bought for comparison. Thanks!
Edit: 8MB/s writes also reported by Antutu System Benchmark, so it might not be a fluke. Also, when transferring files via USB I'm getting 7.5MB/s too. This is crazy! I'm actually looking at getting a cheap 32GB Class 4 card tomorrow but it seems like it'll probably be slower... Although class rating is just a minimum write speed, I doubt most cards have such fast write speeds, especially when they're marked Class 2.
Write: 7.7
Read: 28.9 / 21.2
Pretty impressive for a class 2.

Though I have a 32 class 4, the card that came with the phone consistently transferred just as fast, if not faster, than it. I was always impressed by it.
I too ended up buying my own class 4, but not because the SD card that came with the phone was slow, as you guys know, it is quite fast. My problem was I was burning through them. I burned through three in about three months and they got sick of giving me new ones...lol. Class 4 now for about 2 months, and not a problem, and honestly about the same speed, so it seems.
Hi I noticed in the recent wp7 roms that is is recommended to have atleast
class 6 sd card. Why has this increased? The last 6 months I have been using a 16gb class 2 & and my wp7 roms have been working fine. The last rom I used was pdaimate v1 and it ran flawlessly. Now I invested in a 32gb class 4 card & was hoping to install the latest pdaimate roms with multi fix. Question is how will my new card fare in performance compared to a class 6?

Its still random access speeds that are important, people saying class 6 is probably just what they have working, but its a provable fact cards with a slower random R/W, cards do not work, tied to that, many (but not all!) Class 6+ cards use a type of prefetching to speed up their sequential speeds, that can slow down random speeds, so sometimes ( but not always!) less than class 6 is better.
Agreed! I have 2 cards performing very different... 1. is a 8 gig Nokia OEM card class 4 - takes VERY long to install apps and watching videoes on youtube and such requires me to wait for the whole video to load as there will be lag otherwise. My other card is a 16 gig Sandisk class 2 - Time for installing apps is acceptable and watching videos on youtube is smooth BUT the batterylife is a lot worse than on my other card!
As you can se class can't tell you how a certain card will perform! Logic would say that the card with the higher class should load faster but on the other hand have poor batterylife - wrong in my case!
So what is the solution you might ask? Trial and error my friend - trial and error That's as simple as I can put it.

Well after loong night of installing wp7 and 4 android builds on my new 32gb class 4 card, everything went smoothly. All builds fly but unfortunatly bad battery life remains..
Just wondering if anyone has any quantitative numbers (or qualitative I suppose) on how much faster different roms run on emmc vs on sd card. I've been running cm7 off a class 4 sandisk for over a year now and it's very snappy and posts great quadrant scores. But I'm wondering how much better that (or other roms) would be if I put them on emmc.
Any thoughts/experiences?
I have two different Cl 4 Sandisk cards that I have used with various CM7 and CM 9 Roms. I have used some of those same ROMS on EMMC and honestly can't tell any difference. I have run off of other (non-Sandisk) SD cards and can tell a big difference.. slower, many force closes and freeze-ups. Nothing quantitative.. just my observations.. I think it all depends on whether you have a good SD card.
hey guys im looking to get back into the note.. love it.. i have a GS3 with a class 10 sandisk. my write speed is about 13MB a sec and read speed is 21MB a sec...
anyone know if its worth getting the extreme sandisk that reads up to 50/80/90MB a sec?
will the note 3 SD card slot even read it at that speeds?
its pretty nice now that note 3 lowest internal is 32GB im sure ill be ok with it for my use but i know i will be wanting more memory later on and samsung some how always release the very high memory later or never..

I bought this card in June for my S4. It transfers at blazing speeds and has been worth every penny.

Avoid Sandisk cards. They have been failing at a high rate, and are slower compared to the competition. I'd recommend getting a Samsung micro-sd card from amazon for just a few dollars more.
I had the ultra in my note 2. Switched to the extreme a month ago when the Lyra started failing.
I found even in the note 2 a noticeable difference in read/write.

Totally agree. I plan to get Sammy's 64GB one for my Galaxy S4....
I'd like to buy the microSD card that runs the fastest when in a Galaxy S5 (Verizon if that matters), and get the biggest capacity version of that card that the S5 can use. Rather than look up and compare the stand-alone specs for microSD cards, I was wondering if any websites or users have done benchmark comparisons of the cards when in the Galaxy S5? Given my criteria, what is the best card that people here recommend?
I found the following thread, which says the S5's max read is 70 MB/s, but the max write is 250 MB/s:
https://forums.androidcentral.com/s...read-write-speed-s5s-microsdxc-card-slot.html
I'm still curious though if there are idiosyncrasies to particular phone/card combos that defy the stated specs. Hence it would be great if someone out there has actually benchmarked the observed read/write speeds for various cards in the S5.
I also ran across a Samsung support answer that the largest card the S5 can use is 128 GB.
