Hi,
Just wondering if anyone has benchmarked their storage cards using SKtools ?
I have a 1GB Toshiba microSD and SKtools shows that the average
Read is about 10000KB/s while write is incredibly slow at 200Kb/s
The card is currently formatted using default specs (FAT). I tried formatting at FAT32 before at 8K cluster size but write speed was even slower than ... 60KB/s.
I plan to upgrade to 80x MicroSD but not sure if it will make any difference.
Any advice or figures to share as well ?
cheers

If you mean that it's slow when transfering via the usb it's because HERMES only has USB1.0
I've noticed that copying files to the phone (to storage card) via USB cable is painfully slow (as compared to say regular USB stick).
Would purchasing a high speed MicroSD (e.g. Sandisk Premier) help or is the phone itself the bottleneck?
Thanks!
Try connecting your phone as a mass storage device, if you haven't done that already.
You can select this when you plug in the usb cable.
Accessing the storage card is way faster then.

I have purchased SanDisk Mobile Ultra (Class 6) and the performance increase in real terms is marginal!

It would certainly help. Also search this forum for tnyynt's SD Tuneup cab. Note that installing that cab only makes much of a difference once you got a faster SD.
The transfer speed of the SD is limited for whatever reason, power preservation, whatever, it's limited to optimize for slower SD cards. So The SDTuneup cab ups this limit, meaning you will notice a much bigger speed difference when using faster SD cards.
i also find the msd card speed poor. especially when you open up a folder with a lot of images every image software takes minutes to scan the folder.
that is very lame
Hi I need more space for my duo 11 and the cheapest way i believe is to buy a micro sd card to increase the size(Don't know if i can swap my hard drive from 128gb to 256gb). I spotted this micro sd card which is pretty good but don't know if i can utilise it to its maximum speed. The card is "Samsung UHS-1 Class10 PRO Micro SD XC 64GB Memory Card", I know duo 11 supports SD XC but it also needs to support UHS-1 for it to use it up to its maximum speed.
On a side note it says
-Read Speed: Up to 70MB/s
-Write Speed: Up to 20MB/s
Does take mean if i transfer files out of the sd card it can go up to 70mb/s and if i want to transfer files from my hard drive to the sd card the transfer speed would be 20mb/s??
Thanks in advance!
That would be the correct speeds assuming all is perfect and no overhead.
You also need to verify that the reader in the Sony is not connected through USB 2.0 or you wouldn't see 70MB/sec reads, more along the lines of 30-35MB/sec.
The duo uses sd cards not microsd. You can use a microsd card with an adapter but a sd card will be cheaper.
I have a 256gb sd card in mine and it works but it's not particularly fast.

That would be the limiting factor as far as the SD card is concerned yes. Operating system overhead would slightly reduce that. Also there would be a limiting factor in what the hard drive read and write speeds are or memory stick or whatever it is the files are being transferred to and from.
I have some questions to pose regarding the Sandisk Ultra 64GB Class 10 microSDXC.
I bought it about a month ago, and when i first put it into my Samsung Galaxy S4 GT-I9505, it didn't read anywhere near 64GB. Hence, i formatted the new microSD with Samsung's format option, and it showed 59.48GB. Worked perfectly from there.
However, i find the default file system of the microSD card really slow in transferring files when i connect my phone to the PC via USB, with the microSD mounted on my phone. I have a Kingston microSD reader, so i used it to connect my microSD to the PC, and tried to wipe and format it to FAT32. After doing so, the storage size became like 27GB. Is there a way to make my microSD running FAT32 system and get it to work on both my PC and phone without any problems with the size?
Anyway, i formatted the microSD again with Samsung's format option, and it went back to normal 59.48GB. However, i used my microSD reader to connect it to the PC, and it couldn't read the microSD card. It prompts me to format it. Is it because my microSD reader does not work with microSDHX cards? Or is it because my Windows PC cannot read the microSD's file system?
Hope someone has an answer, thanks.
P.S I posted this as a reply to an old thread, but realised it was in the Galaxy S3 forum, so i figured i'll post it here.
So you could use the memory card in your card reader after formatting the card as FAT32?
What OS are you running on your PC? If it's Windows XP, support for exFAT needs to be added. You can find more on this here: http://support.microsoft.com/kb/955704
Same problem here.samsung micro sdhc 64gb card with windows 7 and 8.my computer only recognises my card after formating on windows and the storage size goes down to only 30.5 GB.any solution?

Make a low level format.
utilities for that can be found on google..

use a program such as H2testw to see if your microsd card is fake or defective . You can get it from here or google it .

I found the solution. The Kingston USB reader that i used is actually not compatible with my Sandisk MicroSDXC. That's the reason it couldn't read my microSD when i connected it to the PC. I used the SD card adapter that came with the microSD on a newer laptop which has the port, and it read my card perfectly.
Anyway, i ended up putting my microSD back to my phone and formatting it using the Samsung option. Then, i used a program to format the microSD to FAT32, which i don't think is actually necessary as there wasn't any reading/writing speed difference when it came to transferring files.
Cheers.
Micro SDHC 64GB 10 Series
I wonder if someone can help me.
I purchased a Micro SDHC 64GB 10 Series memory card on Ebay - Brand new.
When I opened the packaging, the card first asked me to format the card fr use. At first, The SDHC card worked fine.
But now when I attempt to use it via laptop, The SDHC card doesn't show up on "My Computer"
It's like the card isn't reading at all..
Any suggestions?
Thanks in advance

I've been playing with Windows since Android's grandfather was a tadpole, so in a combination of research and personal expertise I present the following advice...
DO NOT install a SD of a Class other than what is listed in our phone's Hardware Compatibility List - they being a Class 10 MicroSD, MicroSDHC and MicroSDXC - beyond that of 32GB, as you're only looking for trouble. Sometimes bigger is not necessarily better - just ask the people who knew the man that ate himself to death. NAND technologies are getting better by the day, but unfortunately devices grow increasingly incompatible with newer variants of MicroSD's simply because of the changes made within the firmware of the NAND controller. By changing Class outside of the scope of our phone's capability, problems can arise. Kind of like having a PC and trying to use a SATA-M drive on it. Unless you've got the physical hardware and device drivers installed, you can't expect it to work properly, same as throwing a SATA3 drive on a SATA2 port and expecting it to transfer data at over 3Gbps. If you find you are so desperate that you just can't do without having a 64GB card installed, go to eBay and grab yourself a Genuine Samsung 64GB 'Evo' Class 10 MicroSDXC. They are the fastest and highest capacity MicroSD our device will be friendly with (due to NAND controller compatibility) and at the moment they're going for good prices. Once you get it, Format the thing on your phone first, according to Samsung's instructions for installing the card. You'll then have a bit less than 60GB of storage space, along with Samsung backup if something does go wrong, simply because you're running a Samsung card in a Samsung phone. Trust me, its a great combination, proven by the fact my Samsung laptop runs like a dream on the Samsung 840Pro series SSD it has in it's belly...

Good advice but I guess I'm just glad my 64gb card has been serving me well. [emoji41]
my link rate on the phone is 525Mbit/s and my computer is at 1Gbit/s and for some reason im transferring from my computer to my phones Memory card which is a sandisk 128gb and im only getting around 1-3 MB/s write speed, i don't get it shouldn't the sd card be rated for higher? or is it the chip inside my note 4 that bottlenecks the sd card? im using Es media to transfer the files. And no it's not small files it was around 800MB
Write speed to your SD card (external storage) from your pc to your device is slower than transferring the file directly from your pc to your devices' internal storage.

but how can it be so slow? is it the phone storage controller that's bottlenecking the sd card?

I'm not quite sure about that. But I think one of the reasons is the SD card itself. Try to use a microSD adapter, plug it in your PC and transfer a file to it. Is it a lot faster that way?
yeah i can get like 12 MB/s
