Dear forum,
I want to know if XZP is able to support UHS-II speeds for the SD card. I'm thinking in acquire this one Samsung 64Gb but it's just UHS-I. This will be OK to save 4k video without problems?
I don't want to buy a UHS-II card (which are notabily more expensive) if the phone only supports UHS-I speeds...
Thank you! Regards!
The phone supports only UHS-I speeds, and it will never support UHS-II. You can still buy an UHS-II card if you want, since they are backwards compatible, but you will be capped at the UHS-I speeds. No phone and phone chipset have implemented UHS-II support yet.
Where did you learn about the UHS-I?

How did you learn that it only supports UHS-I? I can't find any information other than "SDXC supported". So, in theory it can hold up to 2TB, but where did you learn about the UHS-1?
I've found this thread a little bit late, but for all followed user: The Generation 2 need a second raw of contacts. If the phone has only one raw, it could not support Gen. 2
Not sure, but I have one wich writes up to 90MB/s and reads up to 100MBs (Samsung EVO Plus U3 SDXC I 256GB) (tested in PC) and from SD to internal (reading) I've seen 80MB/s and from internal to SD (writing) most times is about 50MB/s but sometimes it gets higher, not sure if its a limitation or just the pone was busy and the reading speed from internal was slower than it can be
Anyway I doubt it gets much faster with better SD, and that one is actually cheap comparing with others
work with v30 for 4k
UHS Speed Class 1 designates the performance option designed to support real-time video recording with a UHS-enabled host device. UHS Speed Class 3 designates the performance option designed to support real-time video recording with a UHS-enabled host device.

As you can see in the spec sheet, the 835 mobile platform supports .
UFS: UFS2.1 Gear3 2L
SD: SD 3.0 (UHS-I)
So UHS-I speeds are the highest you can get.

Just a quick question about memory cards. I have read on this forum that it is possible to run a 16gb class 6 high capacity secure digital card in a HTC Universal running a Windowmobile 6 Rom 2.09.01_BL__B_V1; can the same also be said for a 16gb class 4 high capacity secure digital card? I have found one on the net that I am thinking of buying but thought to ask before doing so. The item is http://www.amazon.co.uk/Integral-16Gb-SDHC-Class-Card/dp/B000ZOVB0Y/ref=pd_sbs_ce_title_9
I have a contract with O2 and have been informed I am due an upgrade, I have had a look at the O2 Orbit 2, nice looking device; what are the other names for this device as I am unsure?
Thanks for viewing and replies welcome.
Yes ,it support my Toshiba 8gb class4 very well!
the "class" on SDHC cards only marks their speed.
it's the "guaranteed minimum consecutive write speed" in MByte/s
So a class 6 card must be able to handle 6MB/s write speed. It may be a lot faster, but if it's slower you can return it as defective.
The only difference between a class 2 and a class 6 card is that one uses better memory chips than the other, so it can receive/transmit data faster. The interface / layout / pinout / logic / data structure is all the same.
It's like 12x and 52x CD-R. You can use both in any drive that supports either, just the one gets the job done a little faster than the other.
Of course that the card can handle 30MB/s doesn't neccessarily mean your universal can, but it should work (at the universals maximum speed) nontheless.
I'm using a sandisc 16GB SHDC class 6 card at the moment with a Crossbow rom, runs very well.

that is a SICK deal thanks bro:good::good::good:
Just bought mine. This will be a great addition to my S4. Thanks for posting the find!:good::good:
Not to hijack your thread OP, but Best Buy has a class 10 SanDisk 32gb for $32.99. The link you posted lists a class 1 sd card.
I was under the impression that UHS1= Class 10? Either way, for what I need this is a steal. Thanks OP!

I stand corrected, I jumped the gun and overlooked the UHS, I did a quick wiki and this is the word...
UHS Speed Class [edit]
UHS-I symbolThe Ultra-High Speed (UHS) designation is available on some SDHC and SDXC cards.[44] The following ultra-high speeds are specified:
UHS-I cards, specified in SD Version 3.01,[41] support a clock frequency of 100 MHz (a quadrupling of the original "Default Speed"), which in four-bit transfer mode could transfer 50 MB/s. UHS-I cards declared as UHS104 also support a clock frequency of 208 MHz, which could transfer 104 MB/s. UHS-I is the only class for which products are currently available.[45]
Double data rate operation at 50 MHz (DDR50) is also specified in Version 3.01, and is mandatory for microSDHC and microSDXC cards labeled as UHS-I. In this mode, four bits are transferred when the clock signal rises and another four bits when it falls, transferring an entire byte on each full clock cycle.
UHS-II cards, defined in Version 4.0, further raise the data transfer rate to a theoretical maximum of 312 MB/s.[46][47]
UHS memory cards work best with UHS host devices. The combination lets the user record HD resolution videos with tapeless camcorders while performing other functions. It is also suitable for real-time broadcasts and capturing large HD videos.
Cards that comply with UHS show UHS-I or UHS-II on the label, and report this capability to the host device. Use of UHS requires that the host device command the card to drop from 3.3-volt to 1.8-volt operation and select the 4-bit transfer mode.

For future use. Card class is noted on the card itself as well on most cards. You should see a circle with a number in it.
From the picture on the New Egg listing that would mean that this card is a class 10. A lot of the cheaper cards are usually class 4 or below.
Bump...want to make sure as many members get a chance at this amazing deal...especially since I bought one two days ago and paid 30 -_-

WOW that happened quickly...
I am going to buy myself a 64GB micro sd card. I guess I will go with sandisk. But as there are certain sd types there come certain speeds. Such as UHS-ll, UHS-I ,and microSDXC. Now I want to make sure that my phone (SM-G3858) Galaxy Beam 2 is able to do r/w at certain speed levels. But how can I determine that? How can I check if the sd card slot takes UHS-I? I can do a micro sd card speed check when I already bought the sd card (with some apps). But is there any way to check the speed compability BEFORE you even buy the sd card?
I did 3 speeds test on my kingston 18GB MicroSDHC/SDHC Class 10 and the sd benchmark tests were ranging from (max): Read 401,31MB/s Write 10,45MB/s (400 seemed a lot to me, but thats what it said) So that would mean my phone supports at least UHS-l?
I was thinking to buy either the Sandisk Extreme at 45r/45w, the Sandisk Ultra Plus at 40r/lower write or the Sandisk Ultra at 30r/lower write. Or should I go with another brand? Any help is appreciated
thanks
:good:
EDIT: After searching for several hours to find the best 64GB micro sd card I decided to go for the Samsung Evo 64GB. It has full 5 star reviews on amazon and the price was way better than the Sandisk extreme plus. (I paid 37 euros including shipping) This is the best review I found:
"This is a very fast card, particularly suited to not only transferring files quickly but also running as a phone or tablet card for applications as well.
In phones and tablets one of the most important things is not just the transfer speed but also the IOPs that the card can deliver. Many class 10 cards have great transfer speeds but terrible and I mean terrible IOPs, often a 5 year old card easily out performs them in IOPs.
This card delivers in both areas, fast class 10 transfer speeds 23mb read, 15mb write but also 482 write IOPs and 1668 read IOPs.
That's IOP speeds that are slower than an SSD but way faster than a hard disk. Bare in mind that some class 10 cards give 4 write IOPs and you can see why I'm impressed. The only card I have seen outperform it in IOPs it the SanDisk Extreme Pro and they are seriously expensive and not available in 64gb. Testing against the third SanDisk I have, a 32gb ultra, is almost funny as the ultra only gives 15 write IOPs under the same conditions, making this card 30 times faster.
What does this mean for normal use, well it translates into an excellent general purpose card, that even if it doesn't have the official fastest transfer speeds will actually perform much better in the real world. Which is why its getting such rave reviews on here for speed (so long as you get a genuine one!)
This was tested in my Dell Venue 8 tablet using the built in card reader. For the techies (if you've got this far then I assume you are)I am actually using it to run Server 2012 virtual machines in VMWare workstation and the performance is surprisingly good, I would even call it snappy!
Full Crystalmark disk scores below.
Sequential read 23.66mbs write 16.03 mbps
512kb random read 23.25mbs write 15.67 mbps
4k random read 6.40mbps write 1.850 mbps
4k random qd32 6.65mbs write 1.92 mbps
Parameters 5 iterations 1000mb sample size.
Tested on the 64gb Samsung Evo microsdhc."
So anyways..At one point I´ll wait until the price of the Sandisk 128 GB Ultra plus card drops, then check for benchmarks and try out that one. Enjoy the info, im off
Sandisk is having quality issues with 64Gb cards, with many consumers reporting dead cards in a few months.
The Samsung you have choosen is awesome, along with transcend which are rock solid.

I ordered a new Moto G last night, and am looking at memory cards for it. I am considering opting for a UHS-3 card, but am not sure if it will provide any benefits. Thoughts?
PS: I would have thread searched, but it appears the "search within this forum" function isn't appearing or was removed.
there is no such thing as a UHS-3 card
There is bus speed - UHS-I and UHS-II.... this describes the bus speed (aka theoretical max transfer speed between card and device)
More pins on card. I don't think Moto G 3rd gen has this support (don't worry, cards are backward compatible)
https://www.sdcard.org/developers/overview/bus_speed/
There is also Speed classes. Class 2/4/6/10, and UHS class 1/3. These deal with minimum sequential write speeds.
https://www.sdcard.org/consumers/speed/speed_class/
I don't know what "class" Moto G supports though, but I hope this clears up some misinformation
Likely, the Moto G is the bottleneck... get a card that can write/read at 30mb/s, and you should be fine

Yes there is and you even said it yourself. The UHS class 3 cards are marketed as UHS-3 but are for use in UHS devices which I imagine this phone isn't.
Sent from my GT-P5210 using Tapatalk
No. The following cards below exist
UHS-I U1 card
UHS-I U3 card
UHS-II U1 card
UHS-II U3 card
The following card does not exist
UHS-3 card
See the difference? Go take a look at different cards and see how they are described
Ratings: Class 10, UHS-I/ U3
If its anything like the first/second gen, i would say there is no benefit.
I had a Sandisk Extreme Plus 64GB at hand from a year ago. The speed rated was 80mb/s read and 50 mb/s write. However, with the A1 SD Bench software, I can only get 34 mb/s read and 29 mb/s write at maximum in my new XZ.
I wonder if the speed is limited by the hardware of the phone. Are people getting much better results?
I think a lot of it has to do with degredation of SD cards. I'm using a samsung PRO+ 64gb that I bought in november 2015 along with my Moto X Pure, plus I have encryption on SD card enabled...so it goes super slow @ 18mb/s read and write.
If you want better confirmation I'd try to test the same card in a different device, perhaps.

Thanks. Could u try it in ur xz or any sony phone?
Specially just for you, I did a test with my gf's HTC M9. I used SONY microsd-xc, 128gb, uhs-1 class10 advertised 70mb/s card. The M9 did 73mb/s read, 19mb/s write. My XZ, after I turned off SD decryption, did 29mb/s read and 19mb/s write. So yeah xperias probably have slower SD card implementations. But, I only keep music/photos/videos on the SD card and nothing else, so it doesn't really effect me.

Manufacturer-quoted SD card read and write speeds are usually burst speeds, not sustained speeds which are far, far lower. Are you sure you're testing the burst speed, and not the sustained speed?
Sony have since z3c implemented under par SD readers compared to competition. It's quite poor. I had hoped this top of the line Sony would be different. Unfortunately not
Android Snapdragon slow UHS SD interface is a joke
It's the junk Snapdragon SD reader interface bus, not even usb3 just backwards slow. compared to the in-house NVME Apple interfacebus. That destroys all CRAP dragon phones. APPLE has the resources to include a 1 GB a sec buss while crapdragon Android devices have junk for SD interface. Even Samsung's UHS bus is junk compared to Apple. Your encrypting and stuttering Android phone is crap always will be. People edit 4k seemlesly on the IPhone yet on Android it's like sucking pizza through a straw. Atrocious blame it on patents and royalties and guess who has all the best.? Hint =Mac...
