Micro SD card UHS1 vs class 10 - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I currently have a Samsung branded 64gb micro sd uhs1 card in my note 4. I was thinking of upgrading my card so I got on eBay looking up prices for 128 gb cards since the note takes amazing video and those files are HUGE.
Well to my surprise 128 gb class 10 cards are super cheap, like under $20 cheap, while uhs1 class cards are closer to $100.
Is there a significant performance hit using a class 10 vs uhs1?
I downloaded "A1 SD Bench" from the play store, here's the results I got on my uhs1 64gb Samsung card.

If anyone is running a class 10 card, I'd love to see what your bench is using the same app. (Or suggest a different app)
Yes- I ordered a name brand 128 gb micro sd class 10 for $14 [emoji106] [emoji6]
I can't imagine it could possibly perform that bad? But I don't know, that's why I'm asking the question.
Thanks!

You should be getting much faster speeds from the sammy card.

If a 128GB SD card goes for $10 on ebay, then I would be very surprised if that card was legit. The web is rife with stories of knock off cards that are hacked up to look report as a larger capacity than they really are. As the old saying goes, "if it looks too good to be true, then it probably is. "

UHS1 and Class 10 have the same minimum sequential write speed, but Class 10 is compatible with the High Speed Bus while UHS uses the UHS Bus.
https://www.sdcard.org/developers/overview/bus_speed/
Basically, Class 10 cards have a theoretical maximum speed of 25MBps in either direction since that is the maximum bus speed. UHS cards can hit 50, 104, 156 or 312 depending on the bus version used. So if you switch to a Class 10 card you will see your read speed drop significantly (42 per your test results down to 25 at maximum).

My Samsung 64GB EVO card did 36.85MB/s read and 12.11MB/s write.

Will the phone take advantage of the UHS Speed Class 3 devices that claim up to 40MB/s write?

Is the note 4 UHS1 capable?

Wow, UHS3. Ok, that kind of explains the class 10 prices.
Now I'm upset my uhs1 card only got 8mb write [emoji35]

I had a Lexar 64gb class 10 and I was having problems with delay when waking up the screen. I took out the card and the phone was waking up instantly. I then exchanged it with 64gb Samsung Evo and the wake up lag was gone.

I can't believe I'm saying this, but how can a 128gb class 10 micro sd card not be worth $14! ?

Ok, so I bought a SanDisk Extreme Plus 64GB UHS-I/ U3 Micro SDXC and gave it a try.
73.98MB/s read, 41.96MB/s write
Note: Not as good as the "up to" 80 read, 50 write Amazon advertises.

Careful, if it ships from ebay or China at that price, it's fake. Even Amazon 3rd parties sell fakes.

sounds like a fake, to know for sure, once you receive it, fill the card up with movies or whatever... the fake card will crash and you wont be able to use it anymore, it will never reach the 64gb capacity. that is what I do with every card I buy.
$14 please...

It shipped from U.S.A. (can't remember which state) ave I didn't get the "generic" for $12, I sprung for the A DATA branded for $14 [emoji6]
I've used the a data usb thumb drives, and never had issue. I'll check the card when it arrives.
Honestly, I'm fully expecting it to be real, 128 gb capacity, but I'm sure it won't be anything close to my Samsung UHS-1 64gb cards performance.
After the link above, and seeing the note 4 is capable of UHS-3, I'd love to find a good price on one of those, but it would have to be 128gb since I already have a 64gb.
Now the real question is while we all crave the ultimate performance, is that speed difference anything you'll feel in day to day use?

Do a couple of creative Google searches... Read the speed test results from credible testers. The new Samsung cards, rated at UHS1 are faster than most all claimed UHS3 cards.

Yeah, I'm sure that's true. I'm just wondering if the real world, day to day use benefits from the speed? Or is it just a benchmark thing?

Received the 128gb card today. Benchmark was pretty low.

I bought a Samsung 32GB EVO MicroSD from the official Samsung sellers page on Amazon.com

I think they would, given how small this is. I don't imagine it would cost a lot to ship. Mine was send from Hong Kong in a normal envelop. So, worthwhile checking this out, especially the second one which is only around 35 Pounds?

yes it is. Tempted to get one for my Nokia, but it's handy to swap between devices. Play.com deliver free here so the price you see is the price you pay.
Amazon also have 4gb SDHC cards for less than 9GBP!!!!
i'm checking sandisk site but i think the item doesn't include a microsd->minisd converter.
shipping is not an issue for now because i have a friend who's coming from the states.

micro to mini converters are easy to get hold of - you can buy them off ebay for very little. Doesn't have to be a sandisk one, kingston make micro sd memory cards with sd and mini sd adaptors in one box. If you want you could just buy a 1gb microsd off them and use the adaptor with your 8gb, providing you have some other use for the 1gb card! Alternatively, like I said, check ebay.
thanks for the replies guys. i really appreciate it.

I've tried this and it won't work unless you get the sdhc mini adapter from Kingston. This is the only one I could find that supports micro sdhc cards. The adapter comes with a 4 gig micro sdhc card. I have a 6 gig sandisk and this works in the Kingston mini adapter just fine. I also have a regular mini sd adapter and neither of my sdhc cards will work in it. I got my Kingston 4 gig and adapter from Amazon.
Good Luck!

There's no difference between adaptors given with sdhc and sd, it's literally just a pin adaptor with no 'technology' as such. it's strange that you have issues!

I would agree but this micro sdhc card does not work when inserted in this mini adapter
and placed in my Advantage.
I use the same Sandisk card in this Kingston mini adapter and it works perfectly. If I use the regular PNY micro sd card inserted in the mini adapter it comes with, then it works just fine.
Look at the Features/Benefits of the Kingston card w/adapter:
* Compliant — with the SD Specification Version 2.00
* Versatile — when combined with the adapter, can be used as a full-size SDHC card
* Compatible — with microSDHC, miniSDHC, and SDHC host devices; not compatible with standard microSD/miniSD/SD - enabled device/readers
* File Format — FAT 32
* Reliable — lifetime warranty*
Specifications:
* Capacity** — 4GB
* Dimensions — 0.43” x 0.59” x 0.039” ( 11mm x 15mm x 1mm)
* High-Speed Class Rating — Class 4: 4MB/sec. minimum data transfer rate
* Operating temperatures — -13°F to 185°F (-25°C to 85°C)
* Storage temperatures — -40°F to 185°F (-40°C to 85°C)
* Weight — .1 oz (2.7g)
Kingston microSDHC Part Number:
SDC4/4GB-2ADP
If the new micro sdhc card are not backwards compatible with old devices that use standard sd cards then why would you think that a standard mini sd adapter would support the new sdhc. It's obvious that the adapters are not just some passive shells that just convert the pin outs.

They are in fact passive shells. There is a difference between a card 'reader' and a card 'adaptor. A card reader uses hardware to recognise the card and send its information through a USB port. A card adaptor simply alligns the digital and electrical pins so that there is physical contact.
SDHC cards differ to SD cards in terms of their memory addressing protocol but are identical with regard to their physical interface. This accounts for the universal backwards compatibility of SDHC card 'readers' with older SD cards, and why many devices can be made compatible with SDHC cards by means of a firmware update
Hi leoni,
So these two will work perfectly with athena?

Ciao!
the microsd you're looking at buying is vastly overpriced. You can get them here for a lot less through most suppliers. Maybe we're just lucky here in the uk to be able to get them for 29gbp! With regard to the adaptor, you can't really quarantee anything with windows mobile devices, but they should work provided it's capable of reading up to 8gb sdhcs.
Please be informed that 12 GB microSDHC is already out. See this thread.

Replied to you Eaglesteve. By the way I've just bought a 4gb SDHC card off Play.com. It comes with a card reader and SD adaptor, I tested the SDHC in the standard adaptor that came with my old card and it works fine....

32GB micro sd? when?

Anyone have any insite as to when we can get the 32GB Sandisk Micro SD cards?
Take Care
Same Q !!
When ??
UP
[joke]
They have got pressure from Apple so we can't get 32Gb until they release a 64Gb iPhone.
[/joke]
Seriously, they were announced in February last year !
They are arriving now in Hong Kong at Times Square. At least that is what one guy said, 'just released'. However, at this time still buy 16GB because it is SOOOO much cheaper. even class6 cards.
i bought a 16GB card. the 32GB are too expensive...or better overpriced!
the question is valid since HTC doenst say you can use them. the largest i heard htc said can be used is 8GB.... but thats baloney

I called the HTC UK support line when the hotfix for the card reading came out and was told they had tested up to 16 GB cards - so I went out and got one and it works fine.
im pretty sure it said upto 32gb somewhere, so there are some for sale now?!

dying to have the 32Gb micro sd card
I don't think we'll see a 32GB MicroSDHC card any time soon. It looks like the major manufacturers are going to concentrate on the new format SDXC (which can support up for 2TB) .
SDXC is the same design and shape as SD/SDHC but it needs specific support from devices, the Leo/HD2 doesn't, at least officially, support SDXC
However I have been looking and there is a way to convert a larger SD card into a MicroSD card ...yes you read that correctly. You can get a 32GB SD card now (and cheaper than a 32GB microSD if it shows up), then can get a converter from a few places such as APTOlink . I'm not sure this will fit under the Leo's battery cover, but if it will it's the best solution.
cheaper adaptors:

Thanks jagnet. I'm currently using a class 6 16GB Micro SD but I just ordered that DX adapter you linked to because I'm curious to see whether it has a low enough profile to fit into the HD2. It's very annoying waiting for 32GB MicroSD and it would be cool if we could get 32GB capacity now, but cheaper because its on the SD format, and still fit in the phone.

Anything may happen of course, but there's no reason why 32GB SDHC cards shouldn't work. 32GB is the maximum capacity for the SDHC format, and it doesn't require any new drivers, readers or whatever.

Micro SD Cards for the Hero

Was wondering a few questions about upgrading my memory card.
I was looking at getting a 16gb Sandisk Class 2 = $30 ish
Anyone know of any higher or cheaper prices?
Whats the highest class the hero can hold?
I plan on upgrading to the EVO, I know it holds 32gb but which class would be better?
Unless you want to pay more for your MicroSD than for your phone I would just stick with the 16GB, the 32 costs $200. as for the class most people use a class 6 card I think there may be some higher speed classes but that would also incur higher costs.
There's a 16GB Class 10 from Kingston out there for about $100, that's the fastest you'll find.
Here's a LINK to Amazon for a TopRam 16GB Class 4 for about $40 shipped. It's good middle-ground until the 32GB cards drop in price.
8gb card serves me pretty good on the hero, fast access too.

Ok, i was just whining... i just bought one.... I guess it'll be here in a month lol
Been using a class 2 16gb card for a few months now and I can't say I mind the speed at all. The price was right (around $25 at Amazon on sale) and it hasn't given me any problems. The only time I really notice the speed is when loading up my music collection. Other than that...I can't complain.
However, I don't run Apps2sd. If you're planning to do that, you might want to pay extra and go for a higher speed card.
newegg.com has good ones for cheap just bought a 8gb class 4 for 13.00
From Amazon I got a Transcend class 6 8gb card for $21.
I have had serious issues with Hong Kong generic cards (said Sony..but were fake) in the past, so buyer beware. Specifically I had two high capacity memory sticks completely fail within one month of purchase for my modded PSP. I was running Dark Alex's custom firmware and swapping a ton of games on and off the card as well as streaming games over wifi. Under the same conditions my name brand high capacity cards have been working flawlessly for over a year now.
just wait for the release of the 2TB microSDXC..
nah, but seriously.. i would recommend a class 6.. i have a 8GB class 6 Sandisk and a friend of mine HAD* a 8GB class 2 Sandisk, both of us running apps2sd.. and you can really see the difference in performance.. (needless to say, he upgraded to a class 6)
I forked over the money and got a 8Gb class 6 for $24. Don't have a ton of music, but lots of other crap that i don't really need. Mainly got it for apps2sd.
You definitely need a Class 6 card to use A2SD effectively. Otherwise your phone will be choppy or laggy.

Not true, if you have a good class 2 you're fine. I run A2SD and have a Class 2 that doesn't lag any more than before I did A2SD.
I've gotten 7+MB/s when transfering something off of it in disk drive mode

Some class 2 and class 4 cards are capable of performing at class 6 type speeds. You can call your self lucky. I got class 4 and my phone will never function as fast with a2sd as it does without. It will work fine if you dont have the Dalvik cache in your sd. But if you want everything to the sd card it will be choppy. Class 6 speeds are faster (in paper) than internal memory of the Hero. People have reported better performance with a2sd using a class 6 card than internal memory.
You should also try a 2.1 custom rom if you have not done so.
The class refers to minimum write speed, not read. Most Class 2 cards have read speeds rivaling or equaling those of Class 6 cards.

Ah gotcha
Yeah the write speeds aren't terrible but they're a little lower (like 4-5MB/s)

Im starting to get worried. I just got my transcend class 6 8gb micro sd. Im copying the data from a folder in my laptop to the card via a Pro Gear card reader. I have not seen the speed pass the 3.87 MB/second mark. I hope its the sd adapter and the reader and not the card.
Should I be worried??

No. The write speed is measured as total throughput in ideal conditions on an new, empty, formatted card.
~ 4 MB/s as read by Windows isn't anything to really be worried about.

A little tip on microSD cards.

I have just gone through 4 sd cards, all of different brands, about to get my 5th so I figured I give a little insight on class ratings, cost and brands of microSD to help people deciding on which to buy.
The comparisons are among a Sandisk 16GB class 2, Sandisk 2GB class 2, PNY 4GB class 4 and RiDATA 16GB class 6.
Somewhat surprisingly, both of the Sandisks performed significantly better than the other 2 SD cards. My standard transfer rates to and from these were averaged at 4.5 to 5 MB/s, whereas the PNY was typically 2MB/s and the highest I saw was 3.2MB/s, while the RiDATA was actually the worst at consistent 1.9-2.2 MB/s. While the cheapies (PNY, RiDATA, Komputerbay, etc.) seem appealing at a sometimes lower price, they definitely do not perform anywhere near as well as Kingston and Sandisk, which seem to perform above and beyond their specs. Funny thing is I have been seeing the higher end sd cards from the cheap brands, like 16GB class 4 and up, being the same price as Kingston and Sandisk. I am about to receive my next SD, a Kinston 16GB class 4, and have seen nothing but great ratings on as well and is rated by consumers to have a consistent transfer rate of at least 6MB/s. I have also seen reviews on the Transcend SD cards having the same issues as these other low grade brands, but the reviews are definitely mixed because some people report having "quick transfer rates", but I have never used one of these so I cannot say for myself what is true of these.
But in my conclusion, unless you are getting a Sandisk or Kingston, you will be disappointed to find that the card you bought is definitely not even worth a class 2 rating most of the time.
I know some will probably say "Well so-and-so did a speed test on such-and-such card and it did well on it." Well, those do not apply to real world situations where someone is actually transferring differentiating amounts of data to/from the card so I couldn't give a crap about those anymore. I personally have used many SD cards and watched the transfer rates of each one, differing from transferring anywhere between 30MB to 10GB at a time and seen the same transfer rates in each of these cards.
So do not be swayed or fooled by the seductive price and "high rating" of the low brand microSDs, spend a couple extra dollars and get what you're paying for.
I use my class 2 16GB card from my old Droid 1. Flawless and great transfer speeds.
Great write up. I'm considering getting a 16 or even 32gb card. This helps a lot.
Thanks for the write up.
I currently have a SanDisk 4gb SDHC Flash Card. I am thinking about getting a 16gb card.

I just bought me a Transcend 16gb class 6 microsd card and I gotta say the thing is blazing fast. Taking pictures is instant now instead of getting a slight lag I got with the stock 2gb class 2 card, also downloading file attachments is instantanious, before I would be stuck on the fetching attachment screen for what seemed like forever. I highly recommend this card to anyone looking to upgrade.
I am so glad to see this thread, I have been trying to do some detailed research on microsd card comparison lately, but its hard to find anything other than people saying "oh yeah this card is fast" etc, but no real detail. Now I got my new card and am having major problems with it.
I've been using an 8gb Sandisk class 6 for about a year or so, but needed a 16, so after much indecision, I decided on the Transcend 16gb Class 6 after reading some decent reviews on newegg. I received it today and immediately ran some benchmarks on it to compare to my Sandisk, and at first I was impressed.

Sandisk 8gb Class 6 microsd
Transcend 16gb Class 6 microsd
Even though the Sandisk was beating it on the small files, real world performance was great, until I put the Transcend into my phone. For some reason it drags my phone to a crawl, and if I do something that needs alot of access to the card, the phone will completely freeze and require a battery pull. I have tried formatting in the PC, formatting in the phone, I am at a loss and I don't know what the problem could be. It's so slow it can't even play music without skipping. Any ideas would be greatly appreciated.
I was reminded recently that HTC lags up write/read when the sd card is in the phone (bogs down the read-ahead speeds). Ziggy's kernels have a fix coded in to correct this. And with his current new release of kernels that run at stock speed with some light undervolt, I suggest everyone switch to his kernels.
Also, small file read/writes is a little slower on larger SD cards compared to smaller ones. Allocation unit size somewhat plays a role in this as well.
EDIT: I also recommend always formatting through PC and never with phone. The phone format option is defaulted at formatting in FAT rather than FAT32, which can cause issues (i.e. flashing PB31IMG.zip in hboot etc.). Plus you can control the format better on a computer anyways.
earthtodigi did you format the card to fat32? I have the exact same card and its running great, no slowdown at all.

Yes I've formatted it FAT32 in the computer, and in the phone. Tried changing the allocation size as well. I plan to try ziggys kernel just to see, but I don't see why the stock kernel would cause such issues.
What's really weird is, I got two card speed test apps from the market, and on both of them, it outperforms my Sandisk card while in the phone. On one of the test though, it shows 14 Mb/sec write speed, but only 5 Mb/sec read speed, which I assume is the read-ahead issue reportedly fixed by the kernel.
One of the reviews on newegg for this card, the person says they had trouble getting their incredbible to recognise the card, but after they formatted it they had no issues.
I'll let ya know how the kernel goes here in a little bit.
+1 for Sandisk. I have their 16 GB Class 2 and it consistantly does 5 MB/s.
Okay, so I'm not sure what happened today, but I formatted the card, copied everything over, and put it back in the phone, and everything is just fine. I was still getting the low read speeds, but now I tried Ziggy's kernel and all is well. All apps seems to be running smooth, haven't had a hiccup yet. I'm still worried that the gremlins may return, and the card may be flaky, but for now, its smoking fast.
And another one even better...
Just got my SanDisk 16gb class 2 microsd card from Amazon. Will run some tests when I get home and format it. Also, will post the results up later today evening.
I bought the "RiDATA Lightning Series 16GB" from newegg, sold as a Class 6 card. Wanted some extra space, and Class 6 would've been a nice upgrade.
I definitely got some extra storage, but the speed was an all-around downgrade from my 4GB Kingston Class 2 which tested as a Class 5. The highest speed I've seen for the RiDATA is just under 4MB/s sequential read, everything else is abysmal. All speed test apps call it class 2 read/write, and the write speed even falls to class 1 at times. I've tried testing the speed through a usb adapter, through the charging cable... same results. Also tried formatting in different ways and different chunk sizes, nothing.
Probably going to RMA and hope that RiDATA sends me an actual Class 6 card.
Great info! Thanks. Thinking about getting a 16GB card, 4GB isn't cutting it for me.

Highest Capacity SD Card?

What is the highest capacity high speed SD card that will work on the Note 4?
I guess use this thread also as a SD card check.
Show off yo memory!
;p
I just purchased a 128gb card about 3 weeks ago. It is a PNY brand and has worked great!
I have a 128 GB card on my Note 4 and just had another 128 delivered yesterday to replace the 64 gb in my Note 10.1 2014. With the price dropped to $39.99 last week on the sandisk, I couldn't pass it up. :highfive:

That a pretty normal price now. I have this card it works great.
Sadly I'm stuck on an old 32GB SanDisk. Thinking about getting a 128GB for myself for XMas, though I missed a bunch of good sales on Black Friday. Anyone have recommendations on which MicroSD cards are fastest? I've heard around the net that these are fast (in no particular order):
Samsung EVO
Samsung EVO+
Sandisk Ultra
Sandisk Extreme

They have a 512 gb card available but I think the Note 4 can only go up to 128gb according to manufacturer specs.

If only 128gb were available when the note 4 came out then that is all they could test and certify it for. Doesn't mean it's not capable but it could not be tested and advertised.

512GB Micro SD? Really? I've yet to see anything over 200GB. The 512 must cost in the $500 range.
Edit: At present - no company has anything above a 200 GB MICRO sd. A company called Santin has a 256 GB MSD on Amazon but as suspected in test by those you purchased one, it's a fake - only 7GB!
