Hey guys,
i just got an 8gb sd card for my xda star. when i used it with the shipped card reader i was very pleased to achieve about 20mb/s
now that i have it in my phone it's only about 1mb/s maybe even less.
how fast does your usb interface work?
1mb/s=10Mbits
10Mbits=USB1.1
It's normal speed for phone without usb2.0
ok,
the specs say, it's a usb 2.0 link so i expected more
My card is Sandisk 1GB, but it slow too...

I have a Sandisk Wifi + 256 mb card in my MDA Compact and eventhough the driver and such work flawlessly, the wifi performance is very disappointing. With an internet download benchmark I got about 26KB/s througput. I knew the card wasn't going to be fast before I bought it, but I was expecting to get at least something like 100KB/s.
At first I thought the problem was with the card itself, but when I tested an Sandisk Ultra II 256MB SD Memory card with pocket mechanic I noticed that the throughput to the memory card was also very low (0.26MB/s).
The throughput to the supplied mini SD was even worse (0.10MB/s).
Now I am wondering, is there a general problem with the SD bus interface? Can someone verify these results for me?
Or am I mistaken and should I not expect anything more? I did a full SPB benchmark on the device itself and the numbers were even a little better than to some posted in a review.
TIA!
yeah the jam seems to be slow with cards for some reason?!?!
i got a simpletech 10mb read/write one of the fastest and best cards out and i used to get over 1mb read/write on the xda2 with it but on the jam it gets 0.26mb write and 0.78mb read
with my ultra 60x 1gb it only gets 0.23 read and 0.63 write :\
seems so slow
I get similar speeds to this on my XDA II but the SD Card is much faster in an external USB 2.0 reader/writer.
Even worse, I bought a standard speed SanDisk 512k SD card that is so slow, the XDA II can not write to it at all!
I now only buy Ultra 60x or faster SD cards even though you don't get anything like that in performance in the O2 device itself - just reliablilty.
I use an external SD card reader/writer to load it with MP3s etc. I suffer 20 minute backups with Sprite Backup to SD card daily as I have no choice. (I also back up to 2 PCs as well daily - not much faster).

When i try to UL large files to my desire HD I get very slow UL speeds around 2 MB sec max, sometimes it even gets stuck for a minute or so. I tried different USB ports etc.
What are your UL speed on average for larger files? How can I speed up my UL Speed?
Open to any suggestions
Thanks
you are using the wrong cable (UBS)
depending on the SD card class you have in your phone will determine the read and write speeds. I believe you recieve a Class 2 or 4 with the phone.
It depends on your SD card. A Class 2 card will have a max write speed of around 2 MB/s.

LOL.
What SD card are you using? I'm still using the one that the device came with and it's copying at around 6MB/s.
Also If you copying a big as amount of small files the speed will decrease
I get 14MB/sec sustained transfer rate from PC to DHD on Kingmax 8GB Class 10 card.
On the original Class 2 card I get around 4MB/sec.
I've got a 16gb class 4 Dane-elec card and the write speed sometimes goes down to 850kb/s and never goes past 2mb/s
I tried the card in a different phone and also with the adapter to make it an sd card with the same results so i assumed the card was faulty. Getting it sent back for a refund, while copying my data back on to the standard 8gb card that comes with the phone the write speed is at 576kb/s.
Not really sure what to do now, have already reformated the 16gb dane-elec and that didn't help. My next card will be a SanDisk as i've heard good things from them.
Any help would be appreciated.

Might be a fake card. Class 4 should have a minimal write speed of 4 MB/s (actualy it should be even higher). SanDisk is an excellent choice if you have the money.
Hi,
I need some advice here.
I was about to back the kickstarter project for the mini microsd card reader http://www.kickstarter.com/projects...-smartphones-and-ta/posts/458396?ref=activity
However, I saw a usb drive that has a micro usb slot. http://list.qoo10.sg/item/UNUS-SMART-X-OTG-USB-FLASH-MEMORY-4GB/409872086?banner_no=3053
I am intending to use it to store games on it.
I tried using the long otg cable with my sd card to store games previously but i found that there is a certain lag to it.
Do you guys think getting the usb drive will speed up the perfomance? or will the mini microsd card be better?

Not necessarily. It's probably the class rating of the SD card. I would first try to verify what the speed class rating is of your microSD card. If it does seem to be substantial, then you might pursue one of those devices. I'm willing to bet that you just need a faster card.

Hi All,
I was wondering if I'm doing something wrong or if it's just to be expected. I have an S7 edge that I'm attempting to move apps to the SD card and they are just painfully slow, if they transfer at all. I'm using a Samsung Evo 128gb class 10 micro sd card. I've also tried a SanDisk 128gb Ultra class 10 card and it was really really slow. Is there some trick to speed this up? Am I using too beefy of a card? Any help is greatly appreciated!!
move the apps always has been slow even in class 10 sd cards, or at least thats what I remember.... but every other thing is just right

The speed of the external microsd card fully depends on the quality and the specs of the microsd card
itself. That's why some microsd cards are slow or super slow.
I have two 128GB microsd cards, one of them is Sandisk Extreme $80 model and it reads and writes
almost 5 times faster than my other off-brand $28 128GB microsdcard. Both microsd cards are class 10.
I am not talking about speed benchmarks, I am talking about real life transfer speeds under heavy usage..
I also have a 64GB off-brand $17 microsd card which is just as slow as my 128GB $28 off-brand microsd.
All 3 of my microsdcards were purchased at Amazon.com
Good luck,
Have a great day!
I have same problem here I have : https://www.amazon.de/gp/product/B00V62XBQQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
And I go 13Mb/S Write and 60 MB/S Read
((((((
same here...
Just got my S7 and transferring speed from PC to external SD is extremely slow (I tried 64GB and 128GB sandisk class 10 which worked great on my last LG-G3...)
I also tried transferring from internal memory to external SD and it was still extremely slow..
Can it be HW problem (I can send it back for refund - but if it SW issue which can be fixed it would be a better)?
Would someone with an an XZ2 Premium please run a storage speed test on the Micro SD card slot? The XZ2 is apparently gimped compared to last year's XZ1. Which is a real shame.
SD speeds seem pretty bad.
Using A1 SD Bench, running the "accurate w/reboot" test, it achieved only 19.26MB/s read and 21.52MB/s write.
This was with the latest Samsung EVO 128GB U3 card capable of near 100MB/s reads and almost 90MB/s writes as tested on my PC using USB3 (https://www.amazon.com/gp/product/B06XWZWYVP).
Dismal.

Same for me, I also checked my EVO Plus U3 Card on my PC and it was fine, so there does seem to be an issue, the internal memory speed is insanely fast

There's an issue, alright. The issue is that they implemented a pathetic SD card subsystem in an expensive, super-premium phone. It's no wonder that it took so long to generate thumbnails for the photos I transferred over - the SD card read speed (and write speed) is thoroughly gimped.
