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

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.
Hi there!
I've got four 8gb SDHC memory cards and can't really decide which one to put into my andorid phone (SGA). I'm planning on using it as a /data and maybe /cache too. I ran crystal disk mark and got results:

}
Can you help me decide which one to use?
B by far. Although the read speads are about the same, the write speeds are significantly higher.
If only that was that simple..
I've read somewhere that 4k reads/writes are the most important for /data and /cache and those values are greatest in C and D...
B is not bad... High reading and Writing speed is what we want normally.
Found another one, so updated table:
Now it got easy. The best is 'E card', right?

Those speed are great when tested with computer. But it is a completely different story in phone.

You could go with "E", but as melvinchng implied, do not expect the same results (of speed) on your device.
There is actually an app to increase the read speeds on your sd card as well. Most phones are "throttled" to a read speed, so class and read speed don't matter much. If you search the market for "sd card speed fix" you should find it. I use the app and the speed difference when I bring up my gallery is phenomenal.
Lowandbehold is right, but remember that different settings may or may not work as well on different devices (1024 and 2048 are the preferred/best values).

I understand that there are some ways to "tune up" the performacne of sd card in the phone, but it's better to tune a faster card from the beginning, right?
So what's the verdict? Those cards are:
A - AData class 6 8gb
B - AData class 10 8gb
C - Noname class 6 8gb
D - Noname class 6 8gb
E - Sandisk Ultra class 6 4gb
Right now i'm using s2e to increase read buffer size to 2mb.
Or maybe there's a better benchmark than crystal disk?

Have you tried using class 10? The performance should be better.

Right now I'm using class 10 card but I'm wondering if the sandisk ultra would be faster judging by the numbers from the crystal disk test..

SD tools is giving me weird values..
for my 'B card' it measures 9mb/s for writing and 35-40mb/s for reading. Every time I start a new test it gives different reading values. So for me this app is useless

Try multiple test. Take average. 35-40mb reading is normal.

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.

update 10/10/16
This excellent tv box already has update is supposed to optimize the use of kodi not let me put a link but google is "firmware tv box soc S912 yoka KB2 10 10, 2016"
-To update decompresses the files to a flash drive (not the Zip that goes inside) and updated from the app UPDATE Local update mode, select the file USB and click Confirm.
-After updating the TV-Box is interesting to perform a factory reset.
The AE Wish (also known as the AME Wish) AE256 is a Yoka KB2 with a different embossments and a seemingly different and/or older firmware. The latest KB2 firmware works wonderfully in the AE256. When using apps, if any are 64 bit, those are the ones you want. Some CPU controllers have problems with the Octa-Core CPUs. While this has a decent CPU, the Codecs are in need of beefing up and the GPU needs some work. Trying to run true 4K video on the set works limitedly. Have yet to find the actual problem. However it does wonderfully with YouTube 1080 with no problems.
BIG MAJOR PROBLEM: This box does not have access to contacts. The firmware lacks the basics to load contacts or have access to them. Tried loading Google's versions (including the dialer) and got nowhere. If someone has a fix for this, please post it.
"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?"

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.
