Best Micro SD Card...?

Hi guys,
So I recently got an Acer a500 and was wondering what the best MicroSD card I can get for it is. I was thinking about a Sandisk class 4 32Gb SD Card. Is that good? I'm looking for a card that will be fast for supporting apps to SD Card. I also heard Sandisk is the best SD cards for Android. Would a class 10, 16Gb be better? I seen one but not Sandisk. Thanks for the help.

There is no such thing as "best" as there are several dozen manufacturers selling cards, and still almost all the flash chips on them come from the same factories. If you want speed then obviously class 10 is better than class 4. Just make sure you don't buy one from eBay or such as those places sell fakes for suckers who do not know how to check if they are fakes or not.

My adata one I got off new egg a class 4 32GB had been good performs at class four speed and can load to full cap. Without error

I'm thinking of getting a 16Gb, Class 10 flash card Kingston. Don't know if links are allowed otherwise would've linked it. It's $43.

SanDisk Mobile Ultra Class 6 32GB
I'm going for the SanDisk Mobile Ultra 32GB it's a Class 6 30MB/s depending where you are checking you can find it from 43 euros (amazon.de) to 100e, I think it's the fastest, I use SanDisks in all my devices, DSLR, mobile etc, most reliable so far. Not sure why Samsung for example calls its card a Class 10 if it's 24MB/s

Class is the write speed, like class 10 is 10 MB/s. The class bits can't go higher than 10, so it's a limitation of the SDHC specs. The read speed can vary though, so a 30MB/s read means it could probably write that fast, but it can't report over 10. It's set to whatever the mfg thinks is reliable for write speeds.
New interfaces are using UHS (50 MB/s r/w), DDR UHS (95 MB/s) while still calling it class 10 for older compatibility. Then there's UHS-2 which is 4x that.

Sorry to hijackthe thread, but we can go up to 64GB on the iconias, right?

Nope. 32GB is the limit for SDHC. SDXC goes to 2TB, but the Iconia is only compatible with SDHC.

my Asus transformer prime takes sdxc just waiting for some larger spec and cheaper ones to come out currently limited to 128 gb

Oh yeah! My mistake.
Update: It is actually a UHS-I class, just read the description more carefully!

I'm using the Sandisk 64GB SDXC in my A501 and it works fine. I only had to format it in the PC to NTFS.
Sent from my A501 using xda premium

Interesting! What does it show for total space after NTFS format? If it's SDXC compatible, it should be able to handle anything up to 2TB.

It says total memory ("Gesamtspeicher" in German) is 59.46 GB.
I have copied many movies on the card (now only about 14GB empty space is available) and all files can be accessed fine.
It would really be nice to know if this means that we even could use cards above 64GB once these will be available...

SDHC-standard supports only up to 32GB cards, SDXC-standard supports much more than than but A500 does not support SDXC. So no.

There's no reason that it should have any trouble if it can handle 64GB as SDXC and NTFS have an addressable range of 32 bits x 512 (2TB). It's similar to switching from a 16-bit CPU to a 32-bit CPU. There's no 17-bit CPU.
It's hard to believe this has an SDXC interface though, but then the difference isn't as much hardware related as SD to SDHC.

I know that the A500/A501 should not be able to handle SDXC cards.
But at least my A501 does it very well with the Sandisk 64GB card. For everybody with doubts I have attached some proof.

i to have put a 64 gb card in my tablet. It does work . I Have the card formatted NTFS. In 3 partitions.. i actually bought it to use in a windows tablet that i no longer own.
In my iconia i now keep a class 10 16 gb card that is PNY BRAND....I see No reason for anything larger.. With what i use my tablet for no reason to be bigger. the 64 gb card was over 100.00. but got on amazon with a gift card from another site...I also have a 1.8 micro drive. that is 128 gb .. that works awesome thru usb port.. I forget the brand as its in a generic case. i think its a Toshiba drive..Not looking while writing this as its in my purse downstairs...

I actually have a very neat portable hard drive in my phone: it has 32GB internal storage plus it also can be expanded with an SDHC card. And the phone can act as a regular USB drive, so it can be plugged to A500 or whatever. Terribly handy.

Yeah, I don't think I'd buy one right now at $3 per GB or even $100, but that's great news for the future when 32 is considered too small to be useful

[Q] Fastest Comptible Micro SD Card for Note 3

What is the fastest compatible 64GB Micro SD card for the Note 3. By compatible, I mean I don't want to get a blazing fast card that the note can't take advantage of. The reason I ask is I want to minimize processing time when taking full resolution shots with the camera and I want to minimize any potential sd card write lag that would occur when shooting video in 4k. More important than opinions to me are people's experiences with fast micro sd cards on this phone. I'd like to know what you have and how it works in relation to video choppiness and picture taking on the highest resolutions.
Thanks.
Update: I've purchased a Sandisk extreme plus 64gb card and after over a month now, am very pleased with its performance. I made this decision based on reading many reviews about the success of this model versus the ultra series. I'd suggest staying away from the ultra series for 64gb micro sd cards, as I've read lots of failures for this model. The extreme plus is apparently more durable somehow and holds up with much more success. Previously, I used a regular Sandisk 32gb microsd that came with my HTC Thunderbolt, I now have it as a backup in the event that this new card does fail. Stay tuned...

I use a 64 gb san disk class 10 micro sd i got from amazon.com iv had it since the note two cam out and now use it on my note three its the fastest one i have use and ive tried a few the write and read time is unnoticeable its by far the best card ive ever used the only other one i have used that can compare is the new sony 64 gb card i use that one if i fill up my san disk

Here is a link to one of the best microSD cards you can get that is compatible with the phone.
EDIT: you could record the video and then transfer it to the SD card after, and having a faster card would definitely help with that.
EDIT 2: OK I lied, it will record to the card. I could have sworn I saw a pop up one time that said it would only save to device.

I would avoid using high capacity SanDisk usd cards. They are prone to random corruption, which is what happened to me with GS3. Since then, I found XDA threads on the subject and had been using a Samsung usd card in my phone as it had a much better reliability record.
The above is based on my own personal experience and research. There will be plenty of others that will swear by their SanDisk high capacity usd cards, but I personally will not use one in my phone.

Nice. I've used a regular 32gb san disk micro sd that came with my Thunderbolt. Still works great today, but it's time for a faster card. Do you or anyone else notice the write speed difference on the note 3 between extreme version and sdxc?

Some people get bad batches is some people don't. For example I have a 64 gig SanDisk Ultra. And I have been able to run apps to SD, as in running a script to swap the memory units between the onboard an SD card and I've been doing this since the card came out without an issue.

Sandisk Extreme 64GB
I have the Extreme and it's noticeably faster. I noticed it when browsing pictures using QuickPic. If you delete the cache, it recreates the cache faster than any other MicroSD card that I've tried. I replaced a 64GB Ultra with this Extreme and it's absolutely faster.

SD Cards Half Life 2

Since only having 16gb the need for an SD card is high, been using a 64gb Sandisk Ultra which I thought was a good card.
Since trying to play Half Life 2 from the SD it takes ages to load and stutters not a massive deal but annoying none the less.
Did a full test of the nand memory with reboot and that came back at 89 read and 36 write.
The Sandisk came back with 35 read & 7 write.
Gone for a 32gb 633 Lexar card. Roughly 90mb/s read 40mb/s write.* Paid £21 inc cash back.
The only other card I could find faster was the Sandisk Extreme PRO which is only available in 16gb flavour and clocks in at an impressive 90 read and 90 write. Expensive though. £26 for 16gb
The Sandisk Extreme Plus looks good as well with 80read & 50 write, bit more expensive than the Lexar. £30 for 32gb
Should be here in a couple of days, I'll do a few tests and report back.

Great! I look forward to those results.
I've noticed stuttering in HL2 when installed on the internal memory as well - one point got as bad as having 5 second bouts with the sound repeating on a single frame. When you chuck explosive barrels, everything often stops right before impact. I wonder what, if anything, can be done to help this. Luckily, spots this bad are rare.

Am I mistaken that the usb 3.0 adapter it comes with is what gives it the huge speeds? Pretty sure it will still bounce around 30-50MB/s in an actual sd slot.

Hmm strange my old ultra Sandisk gets better reads than those results but the writes seem good.
I doubt one would see 80+ reads in a device but should be better than the ultra, one would expect, a bit of testing will be done.

Would being on optimized be one of the issues with slow game loading? I'd be interested to see if someone could measure the read/ write speed while playing from the internal memory. I'm torn between the 128GB Sandisk Ultra 48MB/s read and the 64GB Sandisk Extreme Plus 80 MB/s.

I imagine that the game would perform better when your tablet is set to max performance and also plugged in. On optimized without receiving any extra power it might have occasional stuttering but still be relatively playable. I've noticed a general smoothness while playing on my couch in console mode that I didn't always have otherwise but it was still common.

OK got the new Lexar card today.

I should be getting the Lexar 633 64gb, on Friday, and ill put some more benchmarks up to compare.

Lexar has been in the flash memory game as long as I can remember (and that includes when CF was common and SmartMedia was the main contender). I've have multiple lexar cards and never had any issues. I suppose they're not as well known as sandisk but they are darn good.

Did a more complex text on the lexar which came back at 73/24ish.
The performance with HL2 is pretty stellar.

The choice in 128 cards is fairly small AFAIK 1 the Sandisk with pretty so so performance with only a max of 30mb/s reads and the Plus 40mb/s reads, which would I think struggle with demanding games like HL2.
I would say that if you had the 32gb Shield and kept demanding stuff on the that it would be less of an issue and the 128 would be fine for normal less demanding tasks.
32/64Gb cards are the performance cards at the moment, something like the:
Sandisk Extreme PLUS 80/50(not to be confused with just the regular extreme 45/30) or the Lexar 633 are considerably faster cards.
Be careful when buying as there are a heck of a lot of copies that don't perform, don't be tempted to buy from an unreputable place based on cost.
I personally have the 32gb Lexar 633 which I found perfect for my needs and fairly cost effective at £21 after cashback :victory:
Nd. I was using a 64gb Sandisk Ultra which was toilet.

Wich SD Card?

Im about to buy a new SD card, since the Adata 64GB Class10 is really slow, im using Link2SD and most of the apps in the SD are really slow, but they run quite fast once I move them back to the internal memory.
Since im in Mexico, this are my options:

I would put speed over capacity atm, especially since we will be able to merge internal storage with external storage in Marshmallow. The 95mb/s seem to be a good fit for this. I benchmarked my phones internal storage a few weeks ago and it was around 125-130mb/s. While the SD cards performance is slower then internal, it probably won't be that noticeable. Go with the one which has the fastest speed. (The fastest SD card atm seem to be 95mb/s)

It's the write speeds you need to worry about, read speeds are pretty reasonable anyway on class 10 and up.
Get a UHS-U3 card because writes are much better, my 64GB Sandisk Ultra UHS-U1 card can manage 50MB/s reads but only 12MB/s writes. The minimum write speed of a UHS-U3 card is 30MB/s and the max i have managed out of my MXP internal memory for writes is 37MB/s so the card isnt much slower which will be great for when Marshmallow comes along.

Everything about this post is wrong. Write speeds are almost pointless on a mobile device. What writing you do is almost going to be bottlenecked by your network connection, unless you are on a very, very fast internet connection (Gigabit+ or recording extremely high bit-rate 4k video (which the MXP can't do anyway)). Read speeds effect everything, from opening an app, loading pics, videos, even games. You have bad read speed, you'll notice it, why OP is noticing a significant performance decrease when he puts apps onto his SD card. He isn't noticing a performance decrease before his phone can't write the data fast enough.
The faster the read speed, the faster apps will load, the faster the cache will be read, loaded into memory and displayed. Read speeds effect the general performance of your device.
Secondly, the read speed of a class 10 SD card is pathetic. Look at my previous post. The phones internal memory reads at 125-130mb/s. Class 10 specification is 10mb/s. That's 110mb/s slower that your phones is reading apps from a SD card then your phone memory. That is a HUGE difference.

And you my son seem to have totally ignored what i was saying about getting a faster card to future proof the phone for the arrival of Marshmallow. My entire post was with respect to writes.
When you have Marshmallow on your MPX and you are *****ing that its really slow installing apps etc after you have baked the SD Card in to the OS as internal storage ill accept your apology.
The write speed of the internal memory on the MXP can muster around 37MB/s with a UHS-I U3 card you can all but manage that. http://forum.xda-developers.com/showpost.php?p=63564670&postcount=2

"Oh no, my app will now take 2 seconds to install, even though it took 10+ for it to actually download" - said no-one ever.
Your technical knowledge is clearly lacking if you think write speeds are more important then read speeds. (given how much U3 read speeds can vary (60mb/s-95mb/s). Pointless me posting here anymore. I'm pretty sure OP has already google'd what SD card is best and been told by numerous other people to go for the highest read speed possible.

Man, chill.
This is a friendly forum, not Facebook/Youtube.
You can put your points forward with a much calmer demeanor.

Once again my point has rocketed straight above your head fella, i am not saying writes are more important than reads what i am saying is if you are going to buy a card you might as well buy one where the writes are as fast as the internal storage if you intend on baking the card in to the OS. Once you are using your SD as the internal storage it isn't just about saving apps, do you honestly think the OS never writes any data whatsoever in the background? Do you think a wizard comes along and magically drops all that cached app data to the phones internal memory?
The read speed of a U1 card is about the same as a U3 card in real life usage but the specification of the card is such that the a U3 card has a minimum write speed of 30MB/s where as a U1 card is only required to have a minimum write speed of 10MB/s. There clearly are substantial gains to be had for a minimal cost.
Anyway you go find that teddy you have lobbed out of your cot and keep recommending slower cards mate, it really is sage advice.

A SD Class 10 works fine, I use a ADATA 32 gb

I
I already own an ADATA class 10, and yes, its HORRIBLY slow. Doing some tests, the internal memory have around 80 to 90 write and read speeds, while the class 10 have a max of 32mb reading speed, and 10 writing.
Since im going to use the external SD for most of my apps and photo/video recording, im not wondering why I experience some horrible performance with my apps on the external SD Card.
So Im sure i should choose anything that is faster than 50mb reading speed.
Going for reading speed actually make sense, using the same idea behind the SSD drives, writing speed in the other hand is useful for cache and video recording, as well for multitasking.
Im not sure how many data android and its apps writes, but im guessing reading is what they do mostly.
Yet, the SanDisk Extreme Pro, have around 70mb writing and 95 reading, so its fair from both sides.

Absolutely, without social skills you better go elsewhere.
Appart from that, with Marshmallow one can merge the SD card with the internal memory so the system treats the memory as one entity. There, write speeds will matter.

New SD arrived. Already partitioned for use it with Link2SD.
So far, it works amazing.

Sandisk Extreme Pro 64GB

I have an error with my phone because all the time the phone says that I have removed my sd.
This is a hardware problem or a software problem

It happened to me before the SD died.
I would check if it is correctly installed.

I have a Sandisk Extreme Pro on order myself so to see some results is great.
This result is with a 64GB Sandisk Ultra UHS-1 and as you can see the write results are crap, i am glad i have ordered the Extreme Pro to use as adopted storage under marshmallow.

My Extreme Pro has arrived and i am a little disappointed with the writes ill be honest, i was expecting 50MB/s+. Mind its miles faster than the Sandisk Ultra i was using.

I kind of want to buy a 128GB for the volume, but I feel like I'd be shooting myself in the foot performance wise... thoughts?
I wonder if I would be better off just getting a 64GB, though I'd use it mainly store offline music on it. I don't plan to integrate it as internal storage.
I'm looking at maybe a Lexar X1000 or Sandisk Ultra.

[Marshmallow] Huge performance hit when formatting Sdcard as Internal

It's a 8GB/1GB version.
The pictures speak for themselves. The Sdcard is PNY Turbo Perf 32GB. The left picture was taken when the PNY was formatted as internal. The internal card performance result in the 1st picture seems misleading, it's actually my sdcard, not the real internal flash memory of the phone.
I believe the sdcard encryption (don't be confused with device encryption) in Android 6.0 deliberately takes away ~50% both read and write performance of my reasonably fast Sd Card.
I am thinking about going back to 5.1.1 where I can move my apps to external storage without any performance compromise.

I put a Samsung Evo 45mbps card in my fathers third gen G and it took a long time to format as internal memory. I also received a message when it was done saying the memory card may be too slow to act as internal memory.
Would love to find a list of cards that don't give that message.

I've put Sandisk cards in 3 G3 phones and they all work exceptionally well. There is a reason that many phone and tablet manufacturers use Sandisk as their internal memory cards.

Thanks for this info. Since I'm planning on doing this myself I guess it'd be best to go with a Sandisk. I didn't think the brand would matter since the sd card and internal phone memory are different types of chips, but there you go.

Buy it from a reputable source if you buy it online, it's also the most counterfeited card. Do a search and you'll find that they even make the packages to resemble a Sandisk package. I purchased a counterfeit card from Amazon once, but they made good on it.

i have 31 MB/s read and 36 MB/s write on internal memory with a SanDisk Extreme PRO 32GB U3

I was really surprised when I got the slow SD card message with a brand new Sandisk Extreme card formatted as internal memory.

I thought pretty much everyone got the slow SD card message, especially since other Marshmallow devices with SD card support had reported that quite a bit as well, and it was just a bogus warning message...

On the 3 G3's I have using Sandisk cards, I've never seen that message. I didn't know that message existed until this thread.

To be clear, we are talking about using Marshmallows "adaptive storage" feature, in particular selecting "internal storage", that is resulting in the slow sd card message. Are you using this same exact feature as well?

I think this might be a problem related to the microsd card interface that Motorola uses on it's low to mid-range phones rather than anything to do with the microsd cards themselves. All of the SOCs that they use (Snapdragon 200, 400, 410) support SD 3.0 (UHS-I) speeds, but I read somewhere that Motorola cheaped out to save costs and used a slower physical interface that severely limits read and write speeds. I can't find a link at the moment; I thought it was on Anandtech, but I'll update the post if I find it. I get this same message on Condor and Surnia.

yeah
performance of SD card is affected
Moto G 3rd Gen Stock w/ Sandisk Extreme Pro UHS-1 U3 = 34.25MBps Read & 49.49MBps Write
Moto E 1st Gen CM13 w/ Samsung Evo UHS-1 U1 = 15.72MBps Read & 9.23MBps Write

Even set up as Portable storage (So no encrytption) the SD card (Well my SD Card Anyway - Sandisk Extreme 32GB) is already 1/2 the speed of the phones internal memory. I wonder if encryption knocks it down another 1/2 - that would suck:

You guys do realise there are different classes of SD cards right? There's generally a little number in a circle on the card, most commonly a 4 which is relatively low performance in comparison to speed class 10. Then you have the UHS variants of speed class 1 and 3 which are ultra high speed and the number is inside a little U on the card.

SanDisk Extreme should be a UHS 3 card.
EDIT: Results with a SanDisk Ultra Class 10 Card (5.1.1 16/2 GB)
i.imgur.com/ist77iw.png
10 stands for min 10 MB/s
UHS 3 is min 30 MB/s so your card is almost meeting that.
Then there is also UHS-I and UHS-II which might be not supported (specially UHS-II which requires extra pins).
EDIT2: The SanDisk Extreme card should also be a UHS-I card so it seems that the Moto G3 doesn't support UHS-I or/and UHS-II.

I biyed sandisk extreme 32gb sd card for marshmallow update,only 20 euro in germany,class u3,and working perfectly by me.With my old card class 10 phone lags alot.
