Great Deal for 32GB Micro-SD ($47)

Picking this up for my G2x and figured I'd share this because it's such a great deal!
http://dealnews.com/A-DATA-32-GB-micro-SDHC-Class-4-Card-for-47-free-shipping/486573.html

A-data and class 4 suck both. Not a crazy deal though thanks for shearing.
Just my 2/100

I've had good luck with them! This will replace the 16GB one in the G2x right now, and I'll continue to use the Adata 16GB card in the Acer A100(finally a fairly priced tablet!). In fact that card was used in my Nexus One, prior to me getting the G2x.

Class 4 is decent; anything above it they optimize it for higher sequential read at the cost of random r/w(class 6 means 6mb/s sequential)...most(if not all) class 4s outperform class 6 and 8 at random r/w

All of my SD cards have been ADATA for years and I have yet to have a single one fail me in any way. Unlike many other brands in the same price range.

So if someone wanted to get an sd and partition a section as swap, you're saying a class 4 would outperform a class 10?

He didn't mention anything about a class 10. And no, a class 4 won't out perform a class 10.

Actually, he did mention a class 10. He said anything above a class 4 is optimized for read and takes a hit on r/w performance. 10 is higher than 4, hence, my question.
So, you're saying a class 10 will outperform a class 4 when used as a swap? I would have assumed that the higher the class, the higher the performance for read and r/w. Had not heard of what bakedpotato was talking about with r/w taking a dive the higher class you get.
Just trying to understand as I am interested in finding the answer.

Just thought I'd share... Unless SD Tools is inacurate for this kind of test, it looks like write is decently faster on class 10 than class 4. Just got my PNY 32 gb sd from provantage (~$55 btw). Ran a test for write and read for both PNY 4gb class 4 and PNY 32gb class 10. Was expecting a bit more from the class 10 on reads but still better than the 4. Screens attached...

I saw a benchmark roundup somehwere(let me see if i can find it) saying so,in addition I found setting up class 4s for swap vs. class 10s didn't yield a clear winnner in terms of user experience. The difference between class 2 and 4 was night and day though.
Oh and what was your benchmark benchmarking? In addition I suspect that size matters when it comes to speed...(no pun intended)

Yeah, really not sure what exactly the benchmark is doing on write tests. It could very well just be writing one big file which wouldn't do well for gauging swap file performance. Not sure. I'm a network and systems guy. Not very good with the hardware side but your original post wouldn't shock me if it were true. Was very interested in finding out.

shows class 4s at the top of the list for small (4kb is I think the block size of a NAND cell most of the time) blocks of random data at a queue depth of 32.
However, I guess what I should've said is that "Class 10/8/6 won't mean any better ux for you on android"

Thx for that. I'll read through it tomorrow. I was thinking about setting up swap on this class 10. Last time I tried to use a swap, I didn't see any improvement. Though, that was on the 2nd android ever realeased (original my touch) and it was running froyo or gb. Ha!
CM7 and MIUI are both really friggin' fast on this phone so not sure it'll do much good.
Have you tried? What about setting a swap internal storage? Possible? Speed?

[Q] 32Gb classes 10 & 6 MicroSDHC UHS-1 not supported by TF300T(G)

Hello,
Preamble: I curently own a TF300TG on JRO03C.WW_epad_10.4.3.9-20121106 stock, locked and not rooted
I've recently bought a Samsung 32Gb Class 10 MicroSDHC UHS-1 and the tablet failed to recognize it, while my i9000 and the PC had no trouble accessing it.
I've tried formatting it again to FAT, exFAT and NTFS without any luck.
Next I sent an e-mail to Asus support, who replied that my and any other card above class 6 is not supported, which seems to be backed up by statements of some people having similar trouble with smaller sized cards of class 10.
This post servers both as a warning to those interested in buying a card for their tablet, and as an interrogative mark for everyone: do you have a working class10 microsd in your TF300T(G)? If so, what make is it, and what firmware are you on? Do you think this is a hardware or a perhaps a stock firmware limitation?
Thanks,
Cheers

I have a microSandisk 32 Gb class 10
It worked on ICS rom from Asus.
Asus JB rom I do not know.
Have changed rom many times.
It works with Surdu_Petrus roms and kernels
Can not get it to work with Clemsyn kernels
:crying:

I'm using a Sandisk 32gb class 10 on my TF300T running JB with no issues at all. :good:

Hi guys,
Given your answers, and to the fact that my old i9000 recognizes it without problems, I tend to incline it'd be a stock firmware limitation, rather than a hardware one... Also I got another reply yesterday from Asus, which among others, reads: "This is a hardware limitation, not a software one. Although with a firmware update you might be able to use your card"
I'm thinking of buying a class 6, and keep this one for my Hero2.

I'm wondering if it's not a UHS related firmware limitation...

Hello and happy new year, I'm back some news:
- Got a Kingston 32GB Micro SDHC which didn't work as well.
- Finally bought a Sandisk 32GG Micro SDHC UHS-1 which finally works without any problem. For future references I've attached below an image of the package I received

The title does not say anything about the dock / extension kb, and we're talking about Micro SD(HC) not about SD cards, but just to make it as clear as possible yes, we're referring build in MicroSD slot.

What is the largest microSD card proven on the PhotonQ LTE? details?

Motorola's website says 32gb microSD is the largest supported by the Photon Q LTE and the Droid 4.
But, I have read the Droid 4 is reading 64gb microSD cards.
So, what is the make & model of the highest GB microSD card that's been proven to be read by the Photon Q LTE stock?
Modded?
Method of Modding?
Recommended microSD card and vendor?
Thanks in advance.
These are the 2 I am deciding between on Amazon:
http://www.amazon.com/SanDisk-Mobil...1364805252&sr=1-2&keywords=Sandisk+Ultra+64GB
http://www.amazon.com/gp/product/B0...le_2?ie=UTF8&psc=1&smid=A02211013Q5HP3OMSZC7W

I'm using the SanDisk 32GB Class 10 microSD card you linked to, and it works great. I've read that 64GB cards work, but I don't own one of my own to verify it.

Typically, 64 GB cards will work, they just need to be formatted to FAT32 before the phone will read them. Most/all 64 GB cards on the market are shipped formatted to ExFAT.
Personally, I am using the 32 GB class 10 SanDisk card with no problems.

Using ADATA 32 GB card, class 10, no problems.

I just tried using one of my 64GB class 10 cards this morning. No bueno. I tried formatting as NTFS or exFAT. FAT32 was not an option for formatting a card that size.
So I tried to format it from the phone directly, but it wouldn't do it.
I believe the support for 64GB is in Android 4.1

You have to format it either over a tool like "MiniTool Partition Magic" or use linux.
Microsoft is blocking FAT32 on "too big" external storages...

32gb SanDisk card here.
I think the 64gb story is correct, it will work formatted FAT32. Use basically anything but the built-in Windows utility to format...

samsung 32gb, no problemo.

I am using a 64 gb San Disk. I have been using it since February with no problems. :good:

You'll have to make sure the card is formatted FAT32. I've heard a lot of the cards larger than 32gb (beyond SDHC) come formatted exFAT.

So, I called Moto Tier 2 tech on the phone and they told me the Micro SD will support Class 10 speeds.
Then, they tell me that 32gb should be the max used.
They said that "If you use a 64gb card, it will cause issues and errors because it will overwhelm the hardward and RAM of the PhotonQ".
I was about to order a Snadisk 64gb Class 10 card, but not I'm not comfortable.
Any thoughts ????

I'm not an expert, but that doesn't make much sense to me. I've never seen that to be the case with anything else, either it works or it doesn't.

I'm also not an expert, but there was a similiar problem on PCs with 32 bit and HDDs with over 2 TB.
Some programs could not use the space over 2 TB or made problems with those HDDs.
Maybe there's a limitation in the ARM architecture?
Can only guess.

The hard drives over 2.2TB is a problem with the MBR

No, that was not the only problem.
In connection with cryptsetup the "plain" module had also problems.
The "plain64" module have no issues. -> http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions#5._Security_Aspects (look at 5.15)
As I said, I am not an expert, but if there exists a plain64 (like 64bit?), I assume the old one was 32bit code.
It's just a guess, I don't know exactly, why the problem exists.

Honestly I think this is just Motorola practicing CYA (Cover Your A**). Most end users aren't going to have a clue that an SDXC card needs to be formatted in FAT32 to work with the phone, nor are they going to know that they need a third party utility to do so in Windows. Motorola probably just doesn't want to deal with support issues and unhappy customers when a 64GB card doesn't work out of the box. I see no real reason why it would "stress the hardware" any more than any other SD card, it doesn't require more voltage or amperage.
There is no issue with the ARM architecture, as it handles 64GB just fine on other phones, once the card is formatted to FAT32.

If you are right, then I am sure, that a 64 GB will work.
A friend of mine own such a SD-card (if I remember correctly), I will ask him if I could try it out.
If he owns this SD-card, then he should be using it with a Samsung Galaxy S3, stock firmware.

Which 64gb microsdxc card will you get?

Just wondering which 64gb microsdxc cards are you guys looking to use with your new s4? WIth al the issues with the sandisk 64, wondering if it's worth paying the little extra for samsung 64gb pro UHS1 (does the s4 support that speed?) Anyone know?
Also are you guys planning to use exfat? I hear some of the roms w/the old s3 had issues with exfat and needed fat32

Haven't heard of any problems with the s4, pretty sure there will be more info by next saturday

So I ended up getting the samsung 64gb microsdxc UHS1 speed rated, and also bought a USB 3.0 card reader that supports it. I suspect however the s4 (like the s3) will not support the higher UHS speeds:

I ordered the same card yesterday. I think the quality is alot better than sandisk. And even if the sgs4 dont support the full speed. It's still worth the few bugs more.
But maybe it do support it? Will have to wait and see.

Yeah the sandisk is no doubt good enough. But the samsung is faster. But the question is. Does the phone even support the ekstra speed.
Sent from my GT-I9300 using xda app-developers app

Don't you have a promotional deal from Samsung in your country? We, in the Netherlands, get a 64gb c10 sd card from Samsung with the S4.

i really love faster loading apps, though i'm normally limited in how many apps i can store on the sd card... however!
-the faster write speed will definitely come in handy when taking dual shot video
-the faster read speed is definitely worth getting UHS-1 but i doubt that you will notice much difference between the sandisk and samsung versions no matter what you're doing.
still, much thanks for the benchmarks, the samsung card will definitely offer a more future-proof solution

How does the Samsung 64GB MicroSD stack up in terms of speed vs the Galaxy S4 internal memory? Also, is it worth the extra $10 or so for the Samsung version vs Sandisk?

my 32gb sandisk was effed in my s3, mounted and unmounted every minute, could take a battery from 100 ~ 30 in an hour with screen off in your pocket.. replaced it with a new one and has worked fine since, there's a visual difference of the memory array on the card, so i think there's a upgraded hw version of the sandisk microsd cards. got my bad one from bestbuy last black Friday

I went with SanDisk because I've had the fewest problems with that brand compared to say Sony or PNY. I tried using the card as exFAT and ran into problems. Furthermore, it's incompatible with CWM (due to the Microsoft patent, they can't include support), so I used guiformat to reformat it FAT32, and now it runs smoothly and is visible to CWM. Having so much room at hand is quite liberating.

For what it's worth, the 64GB Samsung Extreme Pro card is $49.99 at your local Frys (if you have one nearby) until 5/23.

If not, Amazon recently dropped their pricing to $52.98 shipped.

MicroSD. Which one to buy?

I bought a 64Gb MicroSD for little money. It is not brand, but when I copy large amounts of files from the PC (ie music), then when I put it on the phone, the music disappears. This problem can be given by the poor quality of MicroSD? What do you recommend? A MicroSD Samsung Evo may be okay?
Sent from my GT-I9505 using XDA-Developers mobile app

I have made (and still have) good experiences with Samsung, Toshiba and Transcend cards. Rather bad (or mixed) experiences with SanDisk cards. I wouldn't say that SanDisk cards are in general of bad quality - my guess is that there are many fake SanDisk cards on the market.
Currently I'm using a 128 GB Samsung Evo card.
Sent from my black pearl using Tapatalk

Kingston may also be a good option. Using my 32GB Class 10 for well over a year now. Granted, I do not copy much between a PC and the card, but I do move a lot of stuff between the internal storage and the sd card.

Was using a sadisk 16gb card, and now a lexar 32 GB card. Virtually no difference, besides storage space. I find it unnecessary to buy an expensive cardz when I've never had a single problem with the cheaper brands, and not the "top of the line" cards like the overpriced Samsung cards.
Really, go with any brand. I see a lot of articles about certain cards having problems with the s4, but you gotta understand, those are isolated incidences, and the other thousands of people that don't have problems with their SD card and this phone don't go online to complain about them.

As for your particular problem, might be a problem with the connection between your phone and the PC, and not the SD card.
You should buy a different brand, and see if it does the same thing.

The Real SPEED of S4 !!!!!!!!!!!!
I'm a pro of microSD and Galaxy S4.
Hear that :
Galaxy S4 can only read and write on external microSD card at 21,7 Mo/s max !!!!!
So buying a Sandisk Ultra (read : 45, write : 13) would not be a good choice according to me...
You should buy a Sandisk Extreme (read : 90, write : 45), to enjoy a bit more speed, for 3$ more expensive...

I had a bad experience with Lexar ( same for this guy -> https://youtu.be/aO-imP0qTQY
At the moment I'm using samsung EVO+ 128gb and its perfect got it for around 30$US from a store (Best Buy)

SD Cards recommended (and not)
Mostly any BRAND SD cards are recommended. Which ones you ask? Lexar, Kingston, Adata, SAMSUNG. It's going to be sad if you buy a Generic or Off-Brand one. Why? Well, they don't always come with their real capacity (claiming to be 8GB, and they're really 4GB or 2GB), they're REALLY delicate or unreliable, and some are known to not work AT ALL out of box. So yeah, there's the best, VERY-IN-DEPTH guide the world has ever seen. Maybe.

Probably just an isolated incident. Had this lexar for the past 7 mos. and still working flawlessly.

I would recommend KIngston at any form

Got a 32Gb Samsung EVO microsd with my S4 3 years ago - it lasted about 6 months before it packed up. What a bunch of crap from Samsung.
Currently using a cheap old class 4 sandisk 16Gb (which was inherited from my old Blackberry 9300 (from back in the day ) now for the past 2 years or so without hassle - smooth sailing! And the sdcard is probably 4/5 years old now!
Moral of the story: Fastest/most expensive/<insert brand name> IS NOT ALWAYS the most reliable/best way to go.

I always use either SanDisk or Samsung EVO/EVO+, never had issues with either.

So what you're saying is that even though the phone can only read @ 21 mb/s MAX, buying a card that has 90 mb/s read speeds somehow makes it faster?

Yes, S4 is limited at 20Mo/s in read and 20Mo/s in write,
so no benefits at all with a sdcard with 90Mo/s in read,
but 40Mo/s instead of 10Mo/s is a very big benefits(10->2X faster !!!)
So I have bought a 200GB Lexar 633x (90, 40) at 120$, and it works like a charm on my S4 !

EVO 64B here...no promblems yet. :fingers-crossed:

Probably should ask the seller that question?

How much did you pay for it? I find Samsung to be over priced. Got me a lexar microSD card at a cheaper price, and no complaints.
I think brand name SD cards are overrated, IMO. Some of them get bad reviews, and say how they mess up badly after a while, but I think that's just a case of rare instances, or got a defected model. Never had a problem with the cheaper brands, ever.

I use Samsung, but I've also used Transcend which are good and also Kingston are fine.
