Hello everyone. I hope I posted in right section.
Recently I have bought a Samsung SD Card for my Galaxy S3 but I have noticed strange write/read data speeds. Card is formatted as Ext4, and I'm using Cyanogenmod 11 (nightlies). These speeds on this phone are normal or is this card fake?

class 10? write speed should be around 48MB/s
Class 10 means that minim write speed should be 10 MB/s...my SanDisk Ultra 16 GB class 10 results are: write speed 11.35 MB/s, read speed 13 MB/s!
Your speeds are normal for me.

Yes, UHS-I class 10. On the package (See attachment) I see that speeds should be around 48mb/s but I get only ~15mb/s maximum.
On the package there is written up to 48 MB/s which means maximum speed could be around 48 MB/s but on smartphones max speed is around 25-30 MB/s.

If you guys say that is normal. Then thank you for answers. Topic can be closed.

Yes, don't worry because your microsd is normal. You could do a speed test of it on your pc and read speed should be around 40 MB/s our phones are slower then computers.

Supposedly it should have dual channel 32-bit 800Mbps (the same as OMAP4). But apparently utilizing full memory bandwidth might be a bit challenging with ARM Cortex-A9 (at least early revisions). One example is OMAP4: groups.google.com/group/pandaboard/msg/bd03264b6b800900 And another example is here: anandtech.com/show/4225/the-ipad-2-review/4 (just look at the "Stdlib Write" vs. "Stdlib Copy" numbers, somehow "Stdlib Copy" is unexpectedly low for newer iPad 2).
So could anybody from early adopters benchmark memory bandwidth in Exynos based Galaxy S2? It would be very interesting to see the results for memcpy/memset ("Stdlib Copy"/"Stdlib Write"). There are some benchmark applications in Android Market, and one of them which is called "Benchmark" (softweg) seems to be able to provide "Copy memory" statistics.
I'm going to make a decision whether to buy this phone based on this information
Thanks.

It's difficult to compare results of different tests even if they attempt to measure the same thing. But the whole point is that "Stdlib Copy (single-threaded scalar)" benchmark regressed from 740.6 MB/s to 522.0 MB/s in iPad2 when compared to the original iPad according to the data from Anand's article that I linked.
According to the data provided by Intratech (thanks a lot!) Galaxy S2 shows throughput ~700MB/s for memory copy performance in this particular 'Benchmark' program from the Android Market. And on my Galaxy Tab (Hummingbird, Cortex-A8) the same test program shows ~560MB/s. Looks like Exynos is at least somewhat better than Hummingbird, which is very encouraging, considering the troubles encountered by the other vendors. Here is one more link for OMAP4 - computerarch.com/log/2011/03/01/pandaboard/
And this particular benchmark program is not a perfect one. On Galaxy Tab, I can get better memory bandwidth for memory copy by using NEON instructions and boost it to something like ~670MB/s (up from ~560MB/s shown by the benchmark). Which additionally shows that the results from different tests may vary a bit and it's better to run the same test program when comparing different hardware. Also memory latency for random memory accesses is quite important and I don't know any existing test in Android Marked which could benchmark it, but I hope that Samsung also managed this right
With all that said, such low level benchmarks cover only a single aspect of system performance. And good memory bandwidth is important only for certain types of applications. I was just curious whether Exynos could possibly have any memory bandwidth issues or not.
Can please somebody who have L920 make a test with Antutu Benchmark. And some screenshots can be welcome too .

It crashed.
Hmmm why ?
Mine crashes as well, i think Antutu is made for WP7(.5) and not compatible with WP8 yet.

Antutu does not support WP8 it crashes on a 920 ....
But my friend have HTC 8x and there work without any crash
My 820 scores:
Memory: 767
CPU interger: 5738
CPU float-point: 4252
2D graphics: 600
Database IO: 410
Storage Write: (317.7 MB/s) 174
Storage Read: (156.2 MB/s) 221
Total Score: 12162
Pretty much same the same spec other than camera and screen size etc..
Nice HTC 8x have 11700
Thanks for results

Okay, Anyhow I tested it and to me it application FC after I have started the test (maybe after ~5s)
Also noted that one other person had written a review of the program that it crashes on he's 920
---------- Post added at 10:49 PM ---------- Previous post was at 10:37 PM ----------
Okay did some more testing ...
And it is the GPU that is crashing, everything else passes ...
So below is the test result from my 920 without GPU test enabled
Memory: 711
CPU interger: 5986
CPU float-point: 4644
2D graphics: Not tested
Database IO: 425
Storage Write: (535,7 MB/s) 175
Storage Read: (156.2 MB/s) 221
Total Score: 12162
Also looks like the test results wary a bit between runs
This is my Antutu score on Lumia 920

AnTuTu Benchmark Lumia 920
Hey Guys, this is my Result from Windows Phone 8.1 8.10.12359.845
The Benchmark App works very Well! 12015 Points are enough....
Otherwise, whats about the JB for the Lumia 520? That works...Because whats the matter with the Lumia 920 JB?
Does anyone knows anything about that Material??
In the specs it says: CPU runs with 1.5 GHz. But my phone runs with 1.3 GHz... :crying:
Bug? Wrong specs? What is your CPU running at? 1.3 or 1.5 GHz
Besides: The phone is fast as lightning. Just want to know
From what I heard it's real MT6753 1.5 GHz but downclock at 1.3 GHz due to battery power. If this is true, I can say very, very stupid reason.

well, 1.3 is the specs I have seen and that is the same as the phone I have.
frankly I don't need any more speed at the moment... as this phone poops on phones for similar money available over here in the UK.
You could get the ZP999 for even more 'Zopo speed' but then you'd have an older OS, and a non removable battery... and lots of people complaining about having the battery run flat in a few hours... I think the Speed seven is the one to have!
Real specs..

This still doesn't add up... Droid Info app shows there are 8 processor cores, and I can see it is possible to use all 8... but MT6735 only has 4 cores. How do you explain this? Does the phone have two MT6735 chips?
Someone from ZOPO should explain this.... it's an 8 core or a 4 core phone really?
If you look at the screenshot, it mentions first MT6753 and the reports the CPU as MT6735. So there is certainly something wrong and we can not trust it.
Just check the phone with AnTuTu a Geekbench and compare the results with other MT6753 phones. That would make it clear.

In my Zopo Speed 7 plus
For the moment I can not send image (rule of the first 10 messages).
But mè cpu-z sees as 1.30 GHz:crying:
The revision of the processor is the same r0p4
@Netmatrix
Or you tinkering with the new kernel, and / or source code released?
it's my modified kernel but i don't have any speed improvement, and lowered the lowest stage at 199 Mhz

Maybe it helps the battery to last longer!?
"Hi! After reading this thread, I've decided to remove sd card and tablet stopped lag. Then I've formatted SD card to exFat, removed unused files so some music, several books and 3 photos left there. After putting it back, tablet started to lag again.
Today I've run AnTuTu Benchmark with sd and without. 1 test with card, 1 without, 1 with, 1 without. Between tests I've only closed AnTuTu via back button and nothing else.
So results:
With SD1: 3D 28282, UX 38632, CPU 29294, RAM 9185 TOTAL 105393
Without SD1: 3D 53146, UX 41127, CPU 23673, RAM 7392 TOTAL 125338
With SD2: 3D 28743, UX 38650, CPU 22223, RAM 6571 TOTAL 96187
Without SD2: 3D 57138, UX 43860, CPU 24020, RAM 8690 TOTAL 133708
As you can see, 3D and UX are much faster WITHOUT card. It's prettey old ADATA 32GB. No app is installed there. How can this be?"
bY Other XDA USER
I have a SanDisk UHS-1 card installed in mine, and it scored very well:
3D: 56496
UX: 46457
CPU: 30529
RAM: 10436
Total: 143918
Maybe your SD cards are low quality? Also, I'm running the AQF3 Firmware that was recently released in the US.

I bought a new SanDisk extreme 128 GB V30 micro SD Card with read/write speeds of up to 160MB/s / 90MB/s.
But when I test the speed, it was limited to only about 30MB/s / 30MB/s or less. Tested on
1) A1 SD Bench
2) Disk Speed Test
3) CPDT: Storage and Memory Performance Benchmark
All is the same results. Is this normal for Xperia 1?

That's a good question. I have the Samsung Evo Select and only get around 30mb/s as well. Thought it was normal so I just ignored it.
This is true for all Xperia devices over many iterations. Not sure why but I live with it.
What? Haven't used Sdcard for a while as my previous phone does not support it. But wtf? Is it a limitation of the ROM or hardware related?
On the official website did not specify details about micro SD Card clearly so I think maybe Xperia 1 not support UHS-I.
But I found someone test Sony's micro SD Card (UHS-I , speeds of up to 95MB/s / 90MB/s.) on Xperia XZ Premium and it works.
Therefore, I tried to believe that this problem was caused by current firmware and expected to be resolved soon.

I'm afraid that the problem will never get solved. Here is the XZ2 running a lastest software 52.0.A.8.83. Several update got released but it still stuck at around 30 MB/s.

Btw, It strange that devices from 2017 like XZP and XZ1 can be able to achieve a faster speed than the newer one.
Is there an impact of this speed limitation on 4k video recording?
30MB/s saga continues.
funny fact is the speed is slow also in 2021, with their models 1ii and 5ii. Some people even stuff up expensive UHS2 cards inside hoping for better speeds (thou there's no mobile supporting UHS2). The problem lies simply in the cheap reader (cost cut). On the other side, it's better than no SD card support nowadays...
it is best to do a manual test. for some reason the benchmark app doesn't exploit the maximum speed of the micro sd. In A1 benchmark I have 5mb / s in writing and 60 mb / s in reading, 5mb / s is insufficient for the 4k recording however I do not encounter any problem at this level and when I make a manual copy I have peaks at 65 mb / s much higher than the 5 mb / s listed on the A1 benchmark
