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.

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 dont have my gtablet yet, get it next tues, but does anyone know if it will read class 2 sdcards, meritline has this for cheap.
PQI 16GB Secure Digital High Capacity SDHC Card (Class 2), Model 6AEE-016GSR35A-13
I have a Sandisk 32GB class 2, works fine. class 2/4/6/10 are the WRITE speeds. I believe read speeds are the same, if my info is correct.
My local retailer already has stocks for the 32GB Sandisk MicroSD Class 2 card, I know sandisk under rates their cards but Im wondering if anyone has this specific microSD card can tell me how fast it read/writes if its inside the phone..
If possible post some benchmark numbers and the name of the benchmark, no actual screenshot needed, I just want a basis of comparison so my current 16GB class6 Team brand. I really need the space more than the speed though.
Haven't checked the speeds, but I can watch 720p video from my Sandisk Class 2 card, can't think of a use-case scenario where you need to read quicker than that. If you're writing large quantities of data to the phone very often the write speed may be an issue, but I suspect many people are like me and the only time they do that is when they first load their music collection onto the card.

Yeah, first load of music/movies into the card.
Please also remember that there is no standard way of measuring MicroSD speeds at the moment and the present system only really relates to the write speed. For playing content they will all be the same it is when recording HD video that the faster cards come into their own. I have also heard that all class 2 are actually class 4.
I just got the card now and the read speeds as tested by crystal disk is twice as fast as my Class 6 16GB the write speed is only slower at sequential w/c is 4.6MB compared to the 5.xx mb that my class 6 did but all the other write speeds are more than 2x faster!
$88 well spent!!
Yes its still $88 here and its the cheapest you can get!

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.

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.
