SD Card classes - Xperia Arc Q&A, Help & Troubleshooting

Hi guys! I'm planning to buy a new memory card for my Arc S. I just want to ask if it's really worth getting class 10 memory card or should I buy class 4 instead? Originally, I'm planning to buy a class 10, but yesterday I read something that class 4 cards work at par as class 10 cards if used in mobile devices. Someone also said that there's no difference in 720p video recording between the two classes. And now I'm thinking which kind of card to buy, still can't decide. Any suggestions?

32GB microSDHC - Will it work in TP2?

SanDisk ships 32GB microSDHC card for $200
Just curious what the actual limit is of our Touch Pro 2's SD card slot. Currently i have an 8gig in it, but want a bigger one. Thought about 16gig's but would like to put all my music on it.
Also, how fast can the sd slot go? Does it support class 6+ cards?
I believe the Rhodium can handle class 6 cards. but im not 100% sure.
Its max is 32gb.
I was gonna purchase one. But way back when i got my phone 32gb cards didn't exist lol
I've got a Sandisk Class 2 16GB at the moment and its absolutely fine
Pack full of music

Samsung Focus 16GB Class 10 MicroSD

I just wanted to give everyone a heads up. I just bought a Samsung Focus this morning and love the device. The only issue i am having is that it will not detect my class 10 16GB microSD card. I have other 8GB cards and they detect fine but i cannot get the 16GB to work. I have tried the 16GB in other devices (laptop, HTC Hero) and it detects and works fine. So i dont know if it is a size issue or the fact that its a class 10 card but my windows phone will not detect that it is installed.
If anyone has had success with a similar card please let me know.

Are you doing a hard reset on the device after you put the card in?
I have been able to reproduce the same results with a Class 10 MicroSD from Kingston. It is not recognized by the phone with or without performing a hard reset. A class 4 32gb card was recognized with no issues.
Hmmm, class 4 works but not 10??? Class 10 == too fast for Wp7
One more data point. I am also experiencing an issue with the Kingston 16GB class 10 microSD card in a Samsung Focus. Slightly different issue though -- only 8 of the 16GB are recognized.
As you may have seen, AT&T employees are now warning customers to not install microSD cards until MSFT issues a patch. When I bought my Focus this morning, the AT&T salesman brought his manager out to tell me about the problem.
CHANGED: The Transcend 16GB Class 6 card does not work per se. Will see it all 16GB after hard reset, then after turning phone off then on again only sees 8GB of the card.
My A-Data 16GB class 6 card works.
I posted earlier that my Kingston 16GB class 10 card didn't work in the Foucs. I just bought a Sandisk 16GB class 2 microSDHC card, which worked fine. From what I've seen there is no authoritative way to predict which cards will work. However, I have not seen any reports of Sandisk cards failing.
Class 10 cards will not work til update.

it is the class not brand class 10 cards will not work til the update..
Another data point -- I saw instability even with a card that appeared to be working. I first posted that my Kingston 16GB class 10 card didn't work (only 8GB recognized). I then posted that my Sandisk class 2 16GB card worked. However over the next two days, I experienced surprising instability e.g. the phone rebooting itself several times per day. For the last two days I have been running without a microSD card and the spontaneous reboots have gone away. Other people may be having better experiences with their cards. But for the moment, I'll live with less sync'ed music to get better stability. If the spontaneous reboots come back, I'll post again.

You might want to try this card tester on your cards as they mey be bad...
It seems most cards class 6 and above don't work and class 4 is the most reliable. Ho hum!
For what its worth I've been using a Kingston 32GB Micro SDHC Flash Card Model SDC4/32GBSP since Monday and having no problems whatsoever.
Class and size has nothing to do eith it. Google for more info.
Sent from my SGH-T959 using XDA App
The reason Class 10 cards don't work and Class 2 cards do is because of the random read/write speeds. Class 10 cards promise fast SUSTAINED write speed but at the expense of random read/write. Windows phone 7 relies mainly on random read/write speeds to function smoothly. Fortunately, this means that Class 2 cards work very well! I would consider this to be a good thing however because Class 2 cards are cheaper!
Adding to this old dead thread, but was hoping to know if anybody knew if Microsoft fixed this issue yet. I just ordered an A-Data 16GB Class 10 MicroSD recently..
From a quick search, it seems it hasn't though?
Yeah, I don't think anyone has really had an issue with a card since nodo. As stated in this thread however, many people have (in the past at least) had better luck with class 2 than any other class. I've been using the sd card below for a couple of months with no issue with about 30gb of music loaded on it.

Whats the best Memory card for S3

I just got my S3 (United States) and and tried 3 (YES 3) Lexar 32 GB Class 10 cards and every one of them have failed. I called Lexar, they say to have my firmware upgraded. Went to Sprint and verified everything is fine with the phone. The cards won't work in other phones at Sprint Either. Before buying another card I'd like to know from you guys which one out there will work with no problems, speed, and size is important for me. I know I'll be using more memory than the 32gb in the future. I called Sandisk and they recommended their SDSDQUA-032G Ultra 32 Class 10 and said it would work. Sprint says they know the Class 6 works in the S3.
I'd like more than 32gb. and fast write & Read speeds.
Can I get some great recommendations from you before I buy another piece of crap. Two weeks now and I still don't have a working card. Lucky I have Amazon prime membership.

I use a 32gb Sandisk Class 10 SDHC Card, this thing works. Problem with anything bigger then 32gb is that you have to use sdxc and this is only really compatible in fat32 or exfat, for both you have to format the card before inserting into the phone.
Try the SanDisk 32gb Mobile Ultra UHS-1 because it's cheaper than normal class 10 Mobile Ultra and just as fast, and I've been using it a while with no problems.
I am quite happy with my Sandisk Ultra 64GB SDXC. No issues at all.
What do I need to format

I would like the larger size. What would I need to format the bigger size. I wouldn't have a problem with that if I had some detailed instructions.
Thanks.
Sandisc Ultra 64gb micro sd xc1
Sandisc Ultra 64gb micro sd xc1 was my choice and its worked well over the last 4 years. Its the phone that has bricked after Little use in October 27/2016. Changed the battery it needed it. Now its bricked.
I have a SanDisk but I was told that SanDisk aren't good for Samsung S3's
Hello,
I'd recommend the Toshiba Exceria memory card, either with 16, 32 or 64GB. This card is a class 10 card with UHS 3. Although the S3 can't use the full speed of the micro SD, this is a well working combination.
Has anyone tried 128gb sdcard ?
I plan to buy,

I'm using a 128gb card from lexar on it and works fine..
(mine's the i747m just to clear it up...)
I have the SanDisk 64GB ultra sdxc or whatever it's called. It works very well with no issues and I have 1,000+ pictures stored on it with about 30 videos.
Quick question. Would a SD card and adoptable storage on a ROM be a good solution for the Samsung device?
Yes, a SD card is always good, especially for backups

purchase the right Micro sd card

could you tell me what Micro sd card you guys are using,I am fixing to buy one and want to make sure I get the right one,,will this one work
http://www.sandisk.com/products/memo...?capacity=64GB
the micro sd xc is what I am looking at,I appreciate your help thanks
I have a Sandisk class 10 64GB works great
get the fastest and highest capacity your money can buy, on the Note 2 64gb is the limit of external memory.
Im using the 64GB class 10 and its working great. There is an extreme pro available but only comes up to 16GB which is a shame considering transfer speeds are 3 times that of the class 10 one.
64
Im gonna buy the sandisk ultra micro sdxc 64 gb card,thanks for all yalls help...

you know, they with the older phones they always listed 32GB as the maximum, but when 64 came out it worked on many of them. I would bet money that when the 128GB cards hit they will still work with this phone.

For day to day use, you will see no difference on Class 6 or 10 ... if you plan to copy/move large files or music files on a regular basis, then maybe a little ... Will definitely not affect any performance like Camera app, etc.
And I still prefer 32GB Class 10 for now.
64gb C10

there's no such thing as too large of a mem card,
if u have the money then go for the 64gb C10
Does the Note come with a card already installed? I just ordered this morning but have 32Gb SanDisk. I was going to get 64Gb SanDisk and leave 32Gb in my Motorola Photon. If Note comes with card already installed, if lesser I will put that in Photon and sell it

hi,
no,i got my note 2 out of box with no sd card.Had to use my own.
good luck
Class 6 and Class 10 write speed in Note 2 won't be a big difference.
I found Note 2's external memory controller write speed capped at around 10-11MB/s
But for read speed, it will be a BIG difference.
I am using Samsung 64GB UHS-I Pro micro SD.
Having like 55MB+/sec read speed.
with my old Lexar 32GB Class 10 only got 13MB/s read speed.
So, if you concern of read speed, get fastest card you can afford.
if your main concern is write speed, get a class 6 or class 10 would be fine.
And don't get SanDisk ultra. it's known to have problem with Note 2.

I bought mine in Hong Kong for USD 95.
It's expensive yeah but it's the fastest 64GB micro SD you can buy.
It's good for you that you don't have problem with SanDisk Ultra but you can search for Note 2 + SanDisk Ultra.
It has a known problem, after awhile of use or the disk capacity reached certain amount.
Sometimes it will unmount the card or even damage the files in the card.
You can only re format the disk to solve the problem.
MANY people reported this problem. I don't know maybe trigger rate is not 100% but still not recommended.
Darkinners, thanks for your responds and suggestions (which I took and did a search, then some research!)
1. All of these complaints on SanDisk were about the 32Gb Card, not the 64Gb card. All the 64Gb comments were good.
2. The people with issues (both 64Gb and 32Gb) had formatted the card at exFAT, not SDXC. Mathamatically, I can pretty much figure out a.) why it will not write files over 4Gb and b.) why the 64Gb exFAT crashes after it fills over 16Gb! (Think about it, SIII is desinged to read/store 32Gb, not 64Gb even though it will format exFAT. And as for the kid whos computer would not read the 64Gb exFAT, i bet he has 32-bit machine?
3. All complaints were from Europe and blamed on a bad batch of cards (it happens). The one happy individual I saw got his card from Amazon, which is a ligit website. Just because the card says SanDisk, does not mean it actually SanDisk. Cheap forgien vendors use this lable to make them look legit?
4. The card you mentioned and the SanDisk are priced about the same, $59.99USD. I will get SanDisk and format either in phone or my laptop as SDXC and play for awhile. If it piss me off, I will return it!
Again, thanks for your input and suggestions!
