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:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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).

True story...the preferred values do seem to work the best
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.

Try using "SD tools" to see how your SD works

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.

Hi guys. I have a question for you. I have a Samsung Galaxy S3 on the USCellular and from what i understand the US version came with 2gb of RAM.
When i run benchmarks on the phone with Quadrant Standard or AnTuTu Benchmark and when i go to the info part of the apps. This is what you get.
Total RAM: 1623MB available 419mb <------- Antutu benchmark
Total Memory 1662224kb Free 501520kb Inactive: 136464kb <---------- Quadrant Standard
I was wondering if you could maybe run the same app and find out your details if you have the US version .
I though that the number would be higher . I would love to see what number you get.
Thank you
Well international has 1 GB of ram here is the pic, 780 MB usable , and we have 1.6 GB usable i would not complain.

Have you found a working root method for your us cellular version? I'm curious if any of the existing development will be compatible with the us cell version.

So far i haven't attempted any root method yet since we don't even have a UScellular section. lol
I might try the version that is for mac and that works for all the major networks.

Hey guys,
I thought it might be useful to collect some benchmarks about internal memory speed, to see if the problems are consistent through all devices.
I used "A1 SD Benchmark" to check speeds. Please enable "Use longer testing" in Settings to receive more accurate results.
Use this form to post your scores: (just quote to receive the correct BBCODE)

Internal Memory:
Read:
Write:

----------------------------------------
you can also attach scores from other parts (like RAM, sdcard, etc.) but i think internal memory is the most important. Furthermore, you might want to add a screenshot to prove that your scores aren't fake.
my speed is:

Internal Memory:
Read: 17.78 MB/s
Write: 2.94 MB/s

Transformer Prime (AndroWok 1.3 JellyBean, Performance mode):
Read: 27 MiB/s
Write: 2.76 MiB/s
Just for comparison:
Samsung Galaxy S3 (quadcore version, Stock JB):
Read: 41 MiB/s
Write: 20 Mib/s
Samsung Galaxy S2 (SlimBean 2.9):
Read: 22.34 MiB/s
Write: 2.63 Mib/s (same speed as Prime)
Asus really screwed this up, they chose to use Flash memory which reads fast but writes very slow.
Curious why the write performance on the Galaxy S2 is so much better compared to the prime even with both having the same flash write speed. Maybe there can be improvements in software. Some ROMs I used on the Prime where significantly less laggying when writing to internal storage (Team EOS f.e.).
Have not tried on my tf201 yet... but here are scores from my samsung galaxy note 10.1

Hey.. lets compare apples to apples...
Internal sd card read/write is 9/6 in the benchmark from the screenshot u uploaded. In galaxy note the same reading is 36.5/12.5
Internal memory in galaxy note is 40/14, which is 34/14 in the screenshot u uploaded for tf201.

This test is a bit confused. "Internal SD card" is in fact the microSD in my slot, while "External SD card" and "Internal memory" are the same (look at total/free size and measured speed: it's the same thing).
My TF201's internal memory test is about 34/14, as you pointed out. The test result you quoted for Galaxy Note is 37/13 - this is long testing. Short testing seems to be very inaccurate and rather random. So, we have Galaxy Note 37/13 and TF201 34/14. Very comparable results.
The weird thing is that my TF201 gives much faster read/write speeds (in particular write) than reported by Urool and Kashban above...

Yes, all benchmarks I reported are with long testing on Samsung galaxy note 10.1.
I would have tested TF201 as well.. but I don't use it so much now.. I have hooked it upto my non-smart TV to play netflix via it. That's all I use my TF201 for, and it works mostly fine for that usage.
Regarding this benchmarking... I think
internal memory = RAM on device
internal SD Card = Staorage space on Device
RAM was always fine on TF201, it's the internal storage where ASUS fitted in class 2 SD cards is the real issue with TF201.
No matter what ROM you load, a class 2 SD card is a Class 2 SD card. will not get better speed.
Galaxy note 10.1 just shows what a real fast internal storage can do.. I/O speed is as important to end user experience as CPU speed...
Actually as a benchmark for the speed of the transformer prime this tool is about as useful as antutu which is to say not useful at all. This test obviously only measures Sequential read and Write scores which are not in the least what causes performance issues with the transformer prime. It is in the random read and write speeds and of those primarily the random write speed where the io bottleneck lives. The only benchmark I have seen that accurately depicts this failing is Androbench.
funny side note: mine just got picked up by UPS is getting reviewed by Asus customer Support (they told me to do so after sending them my benchmarks)
I'll report what they will come up with
report from Asus Repair Service:
"We have exchanged an (obviously) damaged USB-Cable and reset your device's BIOS".
lulz, let's see if it has helped ANYTHING.
Will be reporting.
Our synthetic benchmarks will undoubtedly reflect those benefits. The previous system's stock memory bandwidth was slightly higher.
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.

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.

"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.

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
