Maximum read/write to sd card speeds - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi all,
What's the maximum speed the Note 3 can read and write to its expanded micro sd card?
As just got a Samsung 64Gb Pro and I'm only getting 20mb/sec read and write. The card is supposedly be 90/80 read/write.
Thanks
Paul

Reading should be fine... but writing seem to max out 20mb/s - so you're getting the average/max speed, but you will notice the file type and size will have impact on speeds. I've seen upto 34mb/s on some mp3 or image files, but otherwise speeds hover around 20.
Wish knew that before right? Could have saved some money on getting a slightly slower sd card, but if you use a good card reader (yeah you have to remove the sd card) you will get your max speeds.

weird XDA neo camera problem for saving file in storage card

I'm facing a weird problem for O2 xda neo. while the picture files are saving in storage card, the picture distorted. Not only the pictures but also the video files. But when the files are saving in the main memory every thing is fine. At first I thought it was the camera problem. But after cheking I find that this problem occuers when I want to save the files in my kingston 1 gb sd memry card.
Can an body tell, what might be the problem? and whats the solution? i got hte neo only before 2 months ago. and now i'm having this problem. Is there any tweak can be done as a solution or do i need to change the card?
i'm uploading one picture so you can unederstand the problem.
Did you try another storage card instead?If you did so,does the problem still exist?
Cheers
Do you have the standard budget Kingston SD Card?
At best performance it can only offer
- Up to 5MB/sec. read rate
- Up to 1.5MB/sec. write rate
it is a very slow card, maybe it is too slow for video and photographic performance.
I don't know the minimum standards required, but as I use SAT NAV a lot, I thought it would be better in the long run spending a couple of extra pounds on a high speed card.
As such everything I run on the card, runs great.
NewSPV,
which SD write speeds to you actually get on XDA ?
I observe about 10x worse speeds on XDA than laptop...

Hi
I don't know my actual speeds on the SPV, but I bought a card rated
- Up to 20MB/sec. read speed
- Up to 9MB/sec. write speed
I thought I would need a fast read speed in order for the SAT NAV to keep up with the car at high speeds.
As I said, I have no problems running anything on the card.
hello again,
one of my friend has XDA neo, I tried with his memory card and it was okey with the capturing picture. No prb. So I think it might be the prb with my card. I found that its not a SD card, rather its a miniSD of Kingston. Except for the pictures, all other operations are going fine. Yesterday I bought another 2GB SD card(this time no miniSD), and it works fine for the camera, saving the pictures.
Thanks for all yours reply, these help me to know the speed issue of cards.

Slow saving of Pocket office files to MiniSD card?

Hey there!
It's come to my attention that my XDA Mini S is horrifically slow at saving office documents to the storage card... I bought a 2GB storage card recently that seems to be working fine, apart from this little issue.
It would take up to half a minute or more for example, to save a 47kb pocket word document. When I do the same editing with a file on the internal memory it can be near instantaneous. With Excel it's even worse!
I tested the read/write speed of the card and it came out with a read speed of about 7.0x and a write speed of... something like 0.02x??
That's horrifically slow! A friend's card scored 5x and 2x respectively. However writing to the card normally doesn't seem to be so sluggish either, using the PC (with MiniSD<>SD adaptor) or the phone itself.
Any ideas??

Slow files copying to external SD when in mobile

When inserted into my laptop the average writing speed is about 6mb/s
When inserted into my Vibrant - the average is about 2mb/s
Why such a huge difference, is there any way to improve the speed ?

SD writes faster than it reads?

Hi. I've benchmarked my class 2 SD card with several different benchmark programs (both android and pc) and they all return the same result: read - 1.5 mb/s and write - 5 mb/s. Is this normal?
You might be experiencing what is called write caching.
This would lead to display of higher speeds with small amounts of data.
Try copying a large file - 2GB or more, for instance - and you will see that it will stabilize around your actual write speed at some point. It might still be 5MB/s as the Class 2 of your SD card guarantees minimum speeds, not maximum

Will an all run fastest on SD or internal memory?

It's not quite as daft as it sounds this. When I briefly had a S5 and was trying to speed the thing up I ran a tester app which showed my SD card was capable of faster data transfers than "internal SD." Now I don't know if the note 3 has the same sort of setup but would an app be slower on the external SD as you'd expect, or if there's an advantage to moving stuff to SD aside from making more room for stuff.

It's generally faster on internal memory due to the lag of retrieval from external but not sure now with these new high speed cards. Would depend if the hardware on the Note 3 has the ability to utilise the actual speed of the sd card and the type of formatting the sd card has....
