SD card read/write speed - Sony Xperia XZ Questions & Answers

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...

MicroSD for Froyo - general consensus?

Hello,
Now that Froyo more or less came out and apps will start having Apps2SD function, it's time for a MicroSD upgrade.
What I want is on-phone performance - that running heavy 3D games on SD would perform as smoothly as if it was on internal memory. Is there a general consensus on what brand/class would suffice, and what is overkill? I have no concern over data cable transfer speed, as I'm pretty sure the phone will limit the speed much before the SD card does.
I'm looking at this Sandisk 16gb MicroSDHC Class 2 for $35 after shipping:
http://www.amazon.com/SanDisk-Flash...ref=sr_1_1?ie=UTF8&s=pc&qid=1275145563&sr=1-1
Anyone know if this would suffice?
Past threads have always went on tangents about good brand vs knock offs, how class is important vs. a marketing ploy, etc etc. Has a general consensus been reached in the xda community over what is sufficient but not overkill for onboard performance? Perhaps people who have already ran App2SD and use games and videos a lot have some input.
Thanks
I have a Top Ram 16 Gig class 6 and I think I paid about the same as you looking to pay for a class2. I also have a class2 that I have had for over a year. I used to use it in my blackberry. It still works and it is made by one of the cheap manufacturers.
Argh, I'm suffering from chronic SD corruption. So I'm in the market for a new chip. Think I'll spring for a 32gb this time. What's the latest on one that's both compatible and fast? And cheap too, that would be nice, links appreciated.
Considering that due to the amount of RAM the N1 has your main apps will be loaded already so card speed is not a significant factor, unless you use lots of different apps on a regular basis.
A faster card is beneficial mostly for the time i takes when I am loading up new music and possibly vids if you use it for that
This is the first 32gb MicroSD card I have seen "In Stock" Pretty expensive for a class 2 though.

Im not sure the nexus 1 can handle a 32GB card , wow that's a lot lol, but you can get one for like $30 on ebay... http://bit.ly/9J7u2S
You can get a 16gb class 10 for about $90.00.

Micro SDHC is a standard that supports up to 32gb. Of course it can handle it just fine.
I run a 16gb Class 6 in mine, works fine
bewar ebay, there a lot of folks selling fake cards. They even read as what they were sold as but then fill up mighty quick............
The class is not needed I don't think
I have a class six and have been running games on it from sd for 3 months cant tell a bit of difference. I run linpack from sd and it works fine too!
the only real 32gb card is found here., http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc

I'm running a 32gb Sandisk Class 2 in my Nexus as of last Friday. No problems (apart from a looooong time to refresh the media library after resyncing my music).
You can not get a genuine 32GB Micro SD card for US$40.
A good class 2 card (2MB/s) will offer you the same performance as any other class in your phone.
The limitation is not the speed of the card.
Buy a brand name card with the capacity you require and be done with the complexity.

I don't know too much about transfer rates but basically what you're saying is that a a brand name class 2 card will be just as good as say a class 6? I'm in the market for a new SD card as well, and the class 6 cards are much more expensive. I'm wondering if they're worth it.

No, in a phone they're not worth it at all and people who say so are either selling snake oil or are embarrassed because they've paid for one and are foolish for doing so.
The best I can do just at the moment is this:
wikipedia said:
In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media.

The Nexus, like probably every other phone out there, is a) not typically used for high rate sustained write activities and b) is designed to write to class 2 media to begin with.
If you have a large, highly fragmented sd card higher speeds will help. This of course is easy to avoid in the first place.
Get a higher capacity, class 2, brand name card for the same money and you're away laughing.
NB - If somebody waves a magic wand and all of a sudden the Nexus can record video at 1080p at a high enough bitrate then perhaps my advice would be invalidated... but don't hold your breath for that to happen...

Thanks for the info man! I was obviously misinformed, you just saved me a bunch of money
so just curious. now that CM 5.0.8 comes with 720p recording, would a class 2 still suffice?
I am also searching the web recently to look for a cost-effective high vol microSD. My finding is: don't 100% trust the "class" specified by mfr. I used ATTO Disk Benchmark to test two 8G microSD that I have: Transcend 8G Class 6 and Sandisk 8G Class 4.
<Transcend Class6> Write: 6-10MB/s Read: 16MB/s
<Sandisk Class 4> Write: 14MB/s Read: 20MB/s
From similar test results on the web, it seems that Sandisk uses to under-state the performance of their card. Finally I get a Sandisk 16G Class 2 for my N1, and here is the test result with the same setting:
<Sandisk 16G Class2> Write: 7MB/s Read: 20MB/s
Although Sandisk only specifies it as class 2, it actually performs like a class 6.
I suspect the importance of the speed of the SD card too, coz I think the write speed into ROM, should be way slower than 6-7MB/s (correct me if I am wrong ^_^)... If the speed of v2.1 w/o app2sd is acceptable to you, then v2.2 with 6-7M write speed card should be logically fine with you.

huh that's interesting. i just might pick that up from amazon then..
I Dont think fragmentation makes any difference to write speed, these are not mechanical devices like hard disks.
Also defragging is pointless and shortens the life of the card by increasing the number of writes.

[Q] How to check micro sd card speed capability on a phone beforehand

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.

Which microSD card for Honor 6?

Hello,
I apologize if this question has already been made but I have a little concerns regarding this matter.
I recently bought the Honor 6 online and I'll receive it soon. I'd like some advice for buying a microSD card that meets my needs.
I'd like to buy a 64gb card that is fast enough (mainly for music and also apps), so I'd avoid cheap cards (unless you assure they're more than ok).
I've made some researches and I'm a bit confused about few points.
What do I really need to check in a card? Is it true that for mobiles the most important thing to see in a sd card are the random Read/Write (512K) speeds? Or else I need to check its sequential speed?
According to a lot of speed tests, SanDisk Extreme Pro is one of the fastest sd cards out there but I also read that SanDisk cards have a quite high failure rate after few months of use (true or not?). Being expensive I've no idea if it would be worth or not.
There are also Samsung Pro+, Transcend 633x, Lexar 1033x etc.. They are quite expensive in Europe and I've totally no idea if my future Honor 6 will be able to benefit to all their fast speed.
I've read this review http://www.anandtech.com/show/8425/huawei-honor-6-review/9 and I'm a bit concerned what the reviewer wrote about the Honor 6, I quote the exact text:
"The Honor 6 offers also a microSD card slot in case you want to expand your storage. The OS offers full exFat compatibility and I had no issues with my Samsung Pro 64GB card. I was however disappointed to see that the HiSilicon chip suffers from the same limitation that plagues other SoCs for no good reason: the DWMMC controller in charge of the SD-card is limited to SDR50 speeds, meaning that you won't be able to exceed ~35mB/s transfer speeds on your microSD, no matter how fast it actually is. It still baffles me that OEMs refuse to address this even almost 2 years after the first UHS-1 cards have been made widely available. "
Is this actually true?
Which microSD you recommend me?

Which max SD card speed is supported by XZP?

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.

Micro SD card with Note 20 Ultra

I haven't had an android phone with an SD card since the OG Moto G days and I have heard every now and then that the way they're handled has changed?
Will the Galaxy Note 20 still keep the SD card and the internal storage separate and use the SD card for media, or does it combine the two in to a larger storage area?

It is separate. Like having an extra HardDrive on your computer. You can store media files on either or both of them.

It can't merge the two since it uses different technology.
Internal storage is way faster than an SD card.
The two are separated.
"way faster" ..
the SD storage is "way fast" enough for many things you plan to do with the phone. get a fast high speed card (i picked up the 1TB sandisk) .
burst mode on the camera will be forced to internal storage (user cant change that) . i did some early tests yesterday with the phone's video camera in different formats and aspect ratios and the card handled the throughput nicely.
but for installing application, I would prefer on internal storage rather than SD card even with an A2 rated card.
Yes because the constant IO and polling the card consume the battery faster
Plus, there's no security and encrypting / decrypting make it longer.

If you want best speed performance go with the A2 rated Sandisk Extreme or Extreme Pro. They are expensive of course. For my day to day use I just settled with Samsung EVO Plus microSD. Does the job competently at budget friendly price.

I just bought Kingston 'Canvas Go! Plus' 256GB card, also rated as A2 and I have found a few benchmarks showing it is a bit faster than the Sandisk Extreme Pro at a cheaper price . I have my doubt too but gonna try it when the card arrived. The Kingston card has a lifetime warranty, will see how it performs. I am very curious too.

Let me know about that Kingston card once you get it. Run some benchmarks on it.
I literally just ordered the Sandisk 256GB 15 minutes ago on Amazon for $48. The Kingston is $49. The Sandisk is rated 160MB Read and 90MB write. The Kingston is 170MB read and 90MB write. I checked out that review you posted and seems like a great card. I'm thinking about cancelling my order and getting the Kingston card instead.

From my research the Note 20Ultra doesn't support the higher end micro SDcards anyway. I can't remember the technology names (the different classes of Micro SD cards) but I did some research on what SDcard to get and the super fast micro SD's are useless in the Note20 since it doesn't have the proper tech to support the higher speeds. I wish I could remember how to explain it technically, but I can't remember the terms to use.

In my country the price differ quite a lot so I get the Kingston. Definitely gonna try it esp. on random read and write. You mean UHS-I and UHS-II right? Agree with your point, Note 20 Ultra does not have UHS-II capability, so focusing on random read and write is more logical.

Yes, UHS I vs UHS II. I'm no expert on SDcards. I did do my research though and found out that the super high-end Micro SD's will not reach their full potential on the Note 20 Ultra. I was trying to find out which one to buy to give me the fastest performance.
I just went to amazon and cancelled my order for the Sandisk and was going to order the Kingston. But I got to checkout and the Kingston wouldn't get here until September 24th! So I ordered the Sandisk again since it will be here on the 2nd
I'd still like to know how that Kingston performs for you. I'm going to run some benchmarks on my Sandisk as well. We could make a thread about it to help other XDA users decide which to get.

I just went to amazon and cancelled my order for the Sandisk and was going to order the Kingston. But I got to checkout and the Kingston wouldn't get here until September 24th! So I ordered the Sandisk again since it will be here on the 2nd
I'd still like to know how that Kingston performs for you. I'm going to run some benchmarks on my Sandisk as well. We could make a thread about it to help other XDA users decide which to get.

Yup, we can compare the performance between these 2 cards. Besides speed, another thing to take into consideration is reliability. My previous S7 Edge is running Samsung Evo card and works reliably for almost 5 years now, although it is slow. This Kingston 'Plus' card is newer version of Canvas! Go, so not sure about the reliability. Sandisk Extreme Pro maybe a more reliable card.
For benchmark, not sure which app to test on phone instead on PC. I have 'Anvil’s Storage Utilities' result for the Sandisk card (128GB) tested by myself and comparing the benchmark results with that review link, Kingston actually surpass Sandisk by a bit. Probably can't feel it in real world use XD.
Btw, I have the Exynos version of Note 20 Ultra. Sadly my courier is taking way too long to deliver my card, bought my Kingston on 17th Aug actually

I'll have to do some research to find out the best way to test on the phone. I have the SD version but I doubt the SOC matters in a drive speed test.

I have received my Kingston card and tested it. Using my office PC (WD Blue 1TB SSD) and same card reader (Ugreen brand) for both cards.
Anvil's Storage Utilities benchmark results:
Kingston Canvas Go! Plus (256GB): https://imgur.com/FmSsoX0
Sandisk Extreme Pro (UHS-I) (128GB): https://imgur.com/wZ68Ian
CrystalDiskMark 7.0.0 benchmark results:
Kingston Canvas Go! Plus (256GB): https://imgur.com/l9u1POG
Sandisk Extreme Pro (UHS-I) (128GB): https://imgur.com/QqGNNAE
From the benchmark, Kingston win over Sandisk on almost all criteria but keep in mind that I only tested on 128GB Sandisk card.
Doing a file transfer (Windows 10 ISO file) the speed for Kingston is around 80MB/s while the Sandisk is 75MB/s. I am happy with my purchase Now on my Note 20 Ultra, I have encrypted it but not sure whether it will have an impact on the performance, my guess is it will.

I have edited my reply just now, add in Crystaldiskmark results. I guess there is no significant difference between these 2 cards. Both of them are better than Samsung's Evo XD. Probably best cards for our Note 20 for now.
