many files on SDHC card slows the device down/eats RAM ?

hi, is it true that the device eats more RAM, and gets slower when a SD Card with many files is in use ?
if so, is it the number of programs (links in \windows\start menu\) , or documents, or just the number of files in the FAT32 system that causes it ?

is that true?

does not seem like it is, I tested by simply removing the SDHC , (not removing all shortcuts) - and there were no significant change.
Next time, I'll compare before/after copying in all links that points to SD.

Generally speaking, not at all.
If you put apps there, they may take very slightly longer to start. But once they start, they all run out of ran.
If you have a lot of data files, say music, the music player you are using may be indexing the files in the background. That will slow it down until the files are indexed.
I use an 8Gb card and have never seen a slowdown.

Max 2GB storage access for app !

There you go!

Techticker.co.uk have published this summary of the recently held UK TechDays seminar held by Microsoft to introduce developers to their new mobile OS.
While the 9 minute video by and large cover information we have heard earlier, one issue of note is that apparently each application will only have access to 2 GB of storage on the device, irrespective of the actual size of storage.

Don't really see that as a problem; the main storage hogs are going to be music/videos/pictures, which are handled through accesible libraries without this 2GB limit. Maps for GPS apps could hit the limit, although I think I see the envisaged scenario being more on streamed data with caching.

Yeah I don't see what's the problem here. Just more BS drama from WMPoweruser to generate traffic.

The problem is that it's just heuristic restrictions on the usage of the operating system.
Why would you limit the size of the space an application can use? Is the underlying OS FAT32 and Microsoft is worried that stupid app developers will store everything as one monolithic file and therefore break their app when the store reaches 2GB?
It doesn't make sense, and restrictions that don't make sense -- regardless of what they are -- are a problem.

Yea, this is pretty restrictive, but you guys make it sound like 512MBs. How many apps do you have installed on your device as of now?

No, it's Silverlight Isolated Storage for saving stuff 'on disk'. SIS stores have specificed, finite sizes. Who knows, it might be fat32, might be exfat.

This is limited by Silvelight...
but i don't think this is a big problem,this limitation can easy change by update

This isn't really accurate. They haven't fully decided on a max space. WP7 uses exFAT and isn't limited to a single file size. I believe this can be configured per app and developers will be able to request more than 2GB if their app needs it for whatever reason. 2GB is just the 'default' and isn't even enforced in the CTP. http://msdn.microsoft.com/en-us/library/ff402541(v=VS.92).aspx

My bigger problem with this isolated storage is that for no reason at all other than bad engineering it's incredibly slow. sviluppomobile.blogspot.com/2010/04/wp7-isolatedstorage-speed.html about 127x slower.
When I posted about this on the msdn forum, some MVP just basically told me to "use a webservice" and if i don't than this is not the platform for me.

I had issues with that when i was making some silverlight apps some time ago. But i figured them out. What microsoft is doing here with windows phone 7 is that they are using the phone to marry apps with their cloud counterparts. Apps like netflix ap mobile nytimes will use if at most 10 mb of local storage on the device. anyone that need more than 512 mb of local storage for their app, is doing something really wrong. in regards to speed of the local storage i have realised that each local storage created is essential a true isolated storage area. meaning its essentially a small partiton formatted in some format (might be fat) and all the process of reading from that and storing to it really gets some painful io problems. But it seems with windows phone 7 the unified storage engine seems to fix that. Essential from my views of the way my programs are working. when an app is launched. all other apps are essentialy frozen in their last state, so only essential apps and stacks are running. during this process the local storage is put into ram and the application access the program at close to the native speed of the ram. when a user hits the back button it essential takes the local storage and saves back to the slower storage medium and saves the state of the application..
hope this makes sense.

What do you plan on installing on your WP7? World of Warcraft?
Imho, you don't need more than 2 gigs per app, hell, even my Tomtom with all Europe installed on it fits on my 2 gigs microSD card.
Remember, it's a freaking phone!

[Q] Galaxy Tab Pro 8.4? Need Help!

Hi Everyone,
To start, I would like to say that I have been a big Apple user for many years and I am making the change to Android to get a better understanding of the other side! I like what Google has to offer and looking for that experience.
I have chosen the Samsung Galaxy Tab Pro 8.4 as my first Android based tablet and have some particular questions for those who have purchased this unit. It is hard to find a straight answer when reading some of the other forums out there. Thank you everyone for your help with my transition!!
1, Is the Tab Pro 8.4 available with internal of 32 Gb memory? If so any idea when?
2, Has any who has purchased the Tab Pro 8.4 with 16 Gb internal memory has successfully trying in using Sandisk's latest 128Gb microSD which I understand it to be an SDXC card? Did it work and what amount of external memory did it give you?
3, Lastly, When downloading free or paid apps from Google Play, can the apps you install on device be stored and used from the microSD card rather than the internal memory?
Thanks again Everyone!

Welcome to Android Tablets.
Good choice on the 8.4. The Note 8.0 on the cheap would be another option.
1. Yes. There is 32GB but not very available right now. Mostly for international market than western market.
You can order it online from only a few places right now or wait another few weeks and it should be at more.
2. Yes. The 128GB card will work fine. It gives you 119GB available.
3. Partly. Some data can be stored on the card. This depends on the app. There are some workarounds to improve this.
But it's really going to depend on your use if that's even an issue.

to fully utilize that a SD card to its full potential you must root and use a program like folder Mount to move games and certain apps to the sd card. In addition to this you must change a script in permissions in order to bypass the kit kat limited sd card writing. Google, as always, is fighting micro sd cards as hard as they can. If you search you will find the tutorials on how to accomplish all these things very easily however be aware your knox counter will be tripped so your warranty will be void.

So as a whole from everyone's response, I understand know that there will be a 32 Gb unit available soon, That the new SDXC mircroSD 128 Gb card will work on the Galaxy Tab Pro 8.4 and finally will be able to store apps to a certain degree.
When it comes to the Android tablet experience how important is storage space going to be when in the Google world?
My main purpose for the tablet will be to play stored or streamed music, watch movies hopefully that will be able to be stored quite easily on the microSD 128 card and finally games and some cool apps.
Now as you had mentioned rooting to allow for full usage of what you wish to store on microSD what are some good links or places where I can learn and understand to do it properly?
Thanks again this forum has been a great help!

For most media like images, movies, and any other bulk files. Those can be stored on the card without issue.
Much easier than iOS to manage files. It's basically drag and drop like a thumb drive. Once the files are there your app will pick up on them or can be pointed at them. Gallery app, music player, etc.
Games are the biggest issue of what you've mentioned if you are planning to have a bunch with large data files on the device at once.
Some store to the card better than others but if you want to have a lot of the biggest games it's best you get the 32GB.
You still have the workaround mentionrd above. That would be my chosen route but it depends on the person.

Thanks meboy for your response. So in a nutshell all storable items images, media and music can be reverted to the external SD card other than for the most part apps that are purchased or downloaded for free thru Google play. To get around this what was written earlier is to root your unit to all full controll which I am open too.
Now the final question out here is how do I root the tab pro 8.4 to do this? And when it comes to rooting is there different forms of rooting or just the one that does everything in terms of giving you full control of where you want to store apps that are downloaded?

Any issues getting the KiwiX wikipedia getting on the SD card?

Hi, I'm thinking of buying a new phone and right now I'm looking at the Redmi Note 5 (global version = equivalent of Note 5 Pro). But in review on notebookcheck, I've noticed that this device doesn't allow SD card to be set as the internal storage, and thus the app data can only be stored in internal storage.
One of the main reasons why I buy a new phone is so I can download Kiwix wikipedia on it and have it available when I'm offline - so I'd like to ask, is there any issue getting the apps on the SD card? Or better yet, does anyone have the full kiwix wikipedia on their phone/can someone possibly test it for me? Thank you very much in advance.

When they compare mobile to PC...

UFS 3.0, 12gb ram...this and that...meh

One folder from downloads to DCIM...all internal using file manager

I just tested this with a 3.3gb test file and it took 1 minute 20 seconds. That's about 45MB/s I think.
Not great but there's definitely something wrong with your setup, I'm just testing with my work laptop.

it's normal that it is slow when you move a folder with lots of small files in it

There so much lacking given informations to know what could be the issue here.

yep you will only reach max transfer rates on a single large file, if you transfer a load of little files each file will start basically a new transfer meaning you will never reach the full potential. it's the same on every single digital device a single large file will always beat out a bunch of small ones, be it windows, mac, ios or android, it's just the way file transfer protocols work.

UFS 3 is fast, but data transfer can be slowed down for a myriad of reasons, most commonly the number of files, such as a 2GB folder with a thousand small files, will take wAAAAAy longer than a single 4GB file.
Aside of that, if you're talking about transferring from PC to phone, or vice versa, there's also the unfortunate thing about only one data transfer operation being able to occur at a time.
Maybe you can clarify your issue.

Yeah, plus it depends of the cable, the USB port type used, the transfer protocol chosen, etc etc.

Since I see that someone here didn't understand what I said...I've dl 2200 wallpapers in one folder on my note 10+...transfer that file from download folder of my phone to another folder...that took around 6 min. Just to make it clear, it was not from pc to phone...it was all on the phone.
I've just dl same folder on my pc, and move it from one HDD to another HDD, took not even full minute.
Maybe it could be app that I've use to move it...but I doubt...
BIG EDIT: IT WAS DAMN FILE MANAGER APP!!!
Just used stock file manager from note 10+ and it was almost instant move...lol...

it should be near instant on the same drive as it shouldn't actually move the files, it only needs to change the indexing information for the files, so the new folder structure comes into play, as the files on the drives don't have to be physically located in a certain place to be in a certain folder.
