the best micro sd for optimus?

Hi guys,i,m looking for a good micro sd 32 giga but they are very expensive,anyway which mark is the best? in ebay i can,t find some interesting offer.

lexar,mustang,sandisk...

Another question not really offtopic:
Are there a real performance gain between using a class 4 and a class 6 sdhc in a phone?
Sent from my LG-P920 using Tapatalk

i'm using a class 10 but, in a phone you can't notice any differences between class 10,6,4

I am using a class 4 32GB Sandisk.
Works fine with no problems.

Class 2 = 2mb per sec transfer rate
Class 4 = 4mb per sec transfer rate
Class 6 = 6mb per sec transfer rate
Class 10 = 10mb per sec transfer rate

Well I am using a class 4 micro sd card and bought a transcend one 32 gb for 38€ Works like a charm with out a problem. There is an app which speeds the sd card even up. Sd speed increase, search it in the market. Works great

The thing about the class system is its a MINIMUM rating. So some class 2,4,6 cards will run as fast as a class 10, but they are only guaranteed to maintain their class rating speed.
Notice the speeds I get from the internal SD on the left, my PNY 16GB CLASS 10 on the right:

Its not just BS either, I can actually achieve these speeds over USB Mass Storage mode. No more having to yank the card out and put it in a USB reader to get a decent speed, not with this phone.
It does beg the question though - how fast would modern phones be if they had decent SSDs inside instead of cheap FLASH chips? Like any computer the biggest cause of lag is waiting on IO so if they used better FLASH these things would really fly.

thanks for replays my friends
i,v got this one and hope to work fine. http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=200623957615
Ok,today i,v recieved this micro sd (mustang 32 gig 10 class, i think it,s a very low quality
when I try to make videos, feel a slight click at the beginning that repeats itself after a few seconds, you think this problem depends on the memory card or phone?
any ideas?

Now I hope my little test gave a little bit of Light from speed size...
I bought my Samsung card for about 30EUR(~37USD) @ one of my local internet stores and im freaki'n HAPPY with the speed!
At least when compared with my stock card what came with my device this new card is much much faster! and much much capacious!

This is really a comparison between class 10 and class 4. Seems you overpaid for 32GB as it can be had for $10-20.

your Samsung 32GB is only 29.2GB???? that sucks....my ADATA 32GB is 30.9GB

Is this a comparison of Price or Speed.
As we all know Class10 is faster than Class4.

Wow the Samsung looks really good, i read that class 10 cards had low 4K random R/W values but yours seems really fast on everything, sadly i couldnt find someone who sells them in my country so i bought an Adata 32GB uhs-i, no uhs in sensation so i got class 4 speeds, next i'll go Samsung for sure.

Amazing, well-written test. Thanks for your time.
Got my Samsung 32gb microSDHC card 2 weeks ago because
1. it was the cheapest 32gb class 10 card
2. it is from SAMSUNG
3. amazing writing speeds.
Very satisfied with it. I recomend it.

Depends on cluster size. Larger clusters = bit less space, but a bit more speed.
You can pick the size when you format in Windows.

This test was ment like comparison that stock card is pretty lame against new cards out thare and it is recomended to upgrade... and to see what does samsung card do against stock sandisk

[I9001][Q]Sandisk Ultra Class 10 microSDHC 32GB incompatible?

Hallo,
i've bought a Sandisk 32GB microSDHC and it doesn't run properly. It unmounts/vanishes after some seconds or crashes/freezes the whole OS (Android) if accessed. Same happens in CWM5/6. The card does work properly in Windows though (speed/reliable). Another Sandisk 16GB class4 works properly in the phone.
Anything known about incompatibilities regarding this card? Anyone using it without problems?

I have the same card and it is perfect on my Galaxy S

Thanks.
Anyone else with explicit confirmation on S Plus (I9001)? Seems to have a different controller.

I think it's your rom (if not using stock) because i had same problem on some rom-s

Possible.. but i had this on CWM5/6 as well. Exactly the same issues. Just vanishes with i/o error. In the end a hotswap insert completely corrupted my system partitions (/system, /data at least). The card has been returned. Looks more like a UHS first generation bug or something to me. Maybe they run it out of specs on purpose to get better benchmarks. I don't know. At least I've found other people with same experiences on Google and Amazon that occur on that Sandisk cards.

Also got same card and works fine without any errors. Maybe the sdcard voltage is set too low in kernel or rom

I have the same card and works also perfect.
Running Stock Rom and no errors.
kind regards dekker

Have you tried formatting it with android under settings>storage?

If somebody have problems with SD Cards on Galaxy S than its Sandisk. I use Samsung SD Cards and have never any problems.

I got the same problems and after 3 months of usage the card died and I RMAed it. So be carefoul not to store any extremely valuable data.

sandisk ultra 32gb error on s4
i have galaxy s4 16gb with sandisk ultra microSD HC 32gb. after used a few hours my microSD card can't play video, can't open music or pictures thus can't delete the files. try to format it from options -> storage. it says blank sd card, but it's readable when i open it with windows7. try formatting from windows7 but the problems occured again after a few hours ( seems the problems occured when i tries to play large HD video clip, about 1920 x 1080 pxl video resolution ). is this error caused by sandisk or my galaxy s4 can't work with 32gb card ?

Problem is that Windows doesn't format SD cards properly, just good enough for its own purposes. Download the SD formatter from the SD consortium, and then do a full wipe. Your card now is really formatted as it should, and try again on your phone

Not necessary, I had similair issues as the OP and according to HD Tune my SD was heavely damaged..

[Q] SD Card Fills Up Too Fast

I have a question for everyone.
Are you guys having problems with the internal sd card on your one s?
My sd card gets filled up really quick. I dont have alot on it. Only About 2.6gb of Music & 1gb of Videos
Thats all... The MAX I have is about 4GB with some roms and gapps etc.
If you guys had this issue before how did you guys fix it?
I just barely re-formated my sd card to fat 32 on my mac.
Thanks in advanced

I've been in the same spot. I didn't think I put much stuff on my phone and kept running out of space. Then I found an app from the playstore called "Disk Usage." It's a graphical representation of your phones storage so you can actually see what's taking up space. In my case it's almost always forgetting to delete old back ups. You should try it.
Check it out.

Of course all images are screenshots from my V10, VS990. All apps are the properties of their respective owners and are used for purposes of benchmark/information gathering only on my personal device.
The SD card is unformatted and unedited. All I did was insert it into the phone and start running tests on it. It is exactly how it came from factory with none of my personal data on it.

Literally 30mins before I posted that info. Lol. I was number 15XXX. Filled out the promo info the first day. Took long enough.

What class are these?

Class 10.
Has a little 10 with a circle around it on the card itself.

There's a few other reports for performance on the last few pages of the other thread for those people getting the bonus pack stuff in case anyone is interested:
LG V10 FREE Battery, Charger & 200GB SD Card
And yes it's just a Class 10 card, nothing to write home about, nothing really special save for the massive amount of space and the fact that it's free if you sign(ed) up to get that bonus pack after a V10 purchase - it's fast enough for 4K recording as well even as the max bitrate which works out to about 8MB/s for writes (buffered in the V10's system RAM ahead of the microSD card writes).

I have the AT&T version of the V10. It has issues with letting you write to the microSD Card unless you write to "storage/external_SD/Android/Data/". That being said, I used the app "A1 SD Bench" and got the following:
LG*H900*1m*ago
1.44 GHz ·*v5.1.1*· Accurate benchmark
187,714MB*External SD card*·
SanDisk
...........................................................................R:72.96MB/s
................................W:31.21MB/s
Sent from an AT&T LG V10

A fix for those people who are having problems writing to the microSD Card (as mentioned above). Put the card in a PC and right click on it. "Rename" it or go into properties and "Label" it. On one card I had to format "exFat" & label it.
