When installing apps on the phone, are they installed in the hidden system partition, or on the internal SD card section?
Considering I would use the external SD card mainly for nandroid backups, pictures and videos – both captured by the phone itself, do I need a class 10 card or would a class 4 do?
Thank you.

To start with the internal SD card and the system partition are the same storage, just partitioned and both of them are accessible.
The application apk files are stored in the system partition while the InternalSD is used for user app data. You can store your stuff there too but try to leave a little memory free for your phone to use it without problems.
Secondly, I had an 8Gb Class4 Sandisk before, used it for months without any problem with regular use.
I am using a 16 Gb Class10 SanDisk now, and if you want more storage and use heavy files, like heavy high definition videos and high definition games, you should get a Class10, the read speed is noticeably better.
On side note, each nandroid backup is about 1.8Gb in size so storing them on SD card would be better
Since I am one of those heavy backup guys I am going for a 32GB one.
One this I thought about, I can imagine the card is limited by its reader, any idea if the GRAND even has a class 10 reader, seems like the spiritual father of the grand - the S# has only a class 6 one.

I agree. Most phone's support all class of card but they are limited by their reader. But I don't know which reader is in grand but it definitely supports class 10 cards as I'm myself using it and don't really know how to check it on phones.
Here's a benchmark test using ROM ToolBox Pro :

You get a decent idea of write speed, it's almost twice of the minimum set for any clas 10 card (10MB/s), so safe to assume that it's working good
Always use class 10 mc..

Well I am starting to change my mind and go for the class 10, may I ask which one are you using in that benchmark?

SanDisk Ultra SDHC UHS-I (Class 10) Card 16GB with a boosted read-ahead speed of 4096kb
Well I bought a Transcend 32GB class 10 card, tests are similar to your tiny bit higher, but reads seems way too high (around 300MB/s) maybe SD booster is measuring the internal SD, anyhow thanks for your help!

Currently have a Class 4 card, would a Class 8 card give any speed increase? Does it really pay off to upgrade to a higher class card?
my english that bad or does nobody have a answer?
would a upgrade to class 6 make any difference? (8gb sdhc class 4 to 8gb sdhc class 8)

Normaly it would be faster a class 8 but the artemis will not be any faster. It will not get the max speed of the card.
exactly speed might be a point for digital camera or sdhc card reader, not for PDA. Same for example as with mine 4GB SD 150x in Universal - no diff. in transfer rates between 66x SDcard and 150x. There is max. transfer rate of the mboard - i doubt it can be oveclocked. So if U dont need to transfer helluva lot of datas on daily basis thru SDHC card reader.....better to save some money for beer

Now i'm confused... max throughput of pda = 150x? then i should get a card that can handle that speed, right?
IOW: What is the max throughput of the phone?
I was speaking about classic SD cards (transfer rates are as multiple of ??default speed??) But there is no change in data throughput in device (and same with SDHC) simply transfer speeds are exactly same w/o connection to class or speed of the card in PDA-other thing is card reader. As i wrote above - if u dont need to transfer large amounts of data from PC... no need to have class8
the 8G sandisk card apparently dosnt read as fast as lower class devices. but as someone said the phone isnt at top speed like its wifi being 11mb b not G.
I have a Sandisk 8Gb microSDHC Class 4 in my Artemis ( WM6 touchflo 4 cube ROM) I store all my non ROM programs & files from the card & all video etc is of course stored on the card.
Cant say I noticed any lag vs smaller 2Gb Sandisk microSD card. I tried loading video on Device Memory to see if it played better & it didnt .

Hi, I have a HTC P3300 with Windows Mobile 5 installed. I bought a Trascend microSDHC 8 Gb Card but the system doesn't recognize it. Do you know how could it work?
Thanks in advance.

the original p330 don't read the micro SDHD only the SD type. You have to install a cab that enable the p3300 to read the SDHD, then soft reset. I do in mine and all works fine
Use a tool to format your storage card properly, that increases the speed a lot more. 66x card should be fast enough.
Change the cluster size from 512 Bytes to 4 KB or higher. Note that you will lose free space because every file is at least 4 KB big, even if it's just 1 byte in size.
If you don't have lots of small files this is a good option. My card is now three times faster but I lost about 1 GB of free space.
I recently bought a genuine class 10 Kingston 16GB microSDHC card to replace my class 4 Kingston 16GB microSDHC for my HTC Desire GSM. I have a freshly installed LeeDroid v2.4.1 ROM with S-Off. I did a full wipe/factory reset/format before installing LeeDroid. I created a 15GB FAT32 partition and a 1GB EXT3 partition on both cards for using A2SD+. After comparing both cards (while in my HTC Desire) with 2 benchmark apps from the Market, AnTutu System Benchmark and SD Tools, I'm having some problems.
The problem is that the write performance is almost the same on both the microSDHC cards, around +/- 5 MB/sec. Installing the SD Speed Boost app didn't help in improving the write performance. According to the microSDHC specification I should have at least around +/- 10MB/sec write performance with a class 10 microSDHC card.
I searched a bit here on XDA, and I'm reading some conflicting things. Some say that the HTC Desire supports only up to class 6 microSDHC cards, while others say that the brand new class 10 card they bought on eBay gave them a massive performance boost with max write performance. Also I'm reading that having multiple partitions on a microSDHC card has a negative impact on write performance. Is this true?
Anybody have any suggestions or ideas?
Hello
I have no idea and no suggestions sorry , and I agree with you, everything is strange with writing speed. I think that the "class" is bull**** from my point of view.
Just see my "class 4" card tested with SD tools:

I have a S-ON Desire with Oxygen 2.0.3, and "class 4" 8Go card with a first Fat32 partition (=6.5GGo) and a second partition Ext4 (1Go) ...
I have a class 10 too... but I think Desire's SD handler is the real bottleneck. Did you try and test your SDs on a USB2.0 card reader attached to your computer? You should see the difference among the two.
I just testes my SD performance with SD Tools and I got 8MBs write and 23.5MBs read with a class 2 card. People tend to say that class 6 is better than class 10, in most cases anyway.

wierd isnt it?
16mb writing speed and 8mb reading speed ... thats class 4 kingston card.
not rooted,
Writing speed > reading speed ????
Kingston 4gb class 4 gives me over 8mbps write. ;-) better than Samsung plus class 6.
Also, after some testing I came to conclusion that smaller the size, the faster it is.

probably, my card is 4gb btw if you were wondering why i had such high writing and reading speed
I recently bought an USB 2.0 card reader from Sitecom, but that one broke down on me before I could test the microSDHC cards. The first few days it worked fine, but now it won't recognize any cards anymore...
The results you guys posted really surprised me, such wide variation in performance. Yesterday I called HTC Netherlands and asked them if there are any limitations or restrictions on the HTC Desire regarding the max supported class cards. They couldn't give me an answer straight away (they said I was the first person to ask this question... ), but they are going to do some research regarding this and report back to me. As soon as I get an answer I will post it here.
For now I'm at a loss. The smaller the card the faster it's speed under the same class sounds logical. Also I'm thinking that certain brands might be more compatible or incompatible with the HTC Desire. After researching it some more, I came across some information about people saying that Kingston isn't the best brand to choose for the HTC Desire.
For those who are curious..... HTC Netherlands called me back, after some research at there end they could tell me that the HTC Desire supports up to class 6 microSDHC cards. They also mentioned that some brands are better then other brands when used in there smartphones, although they didn't provide any specific brands.
Hi all.
I have a 32 gb class 6 card (Topram) which I purchased about 2 weeks ago. I partitioned it with a ext2 and converted to an ext3 and had been running Mik 3DSupersonic with a2sd with no problems. Today I was copying the contents of the card to my computer using a card reader and something went wrong. Upon inserting the SD card back into the phone it was unrecognized. I have tried partitioning it with my phone through RA Anon recovery (it completes almost instantly) unsuccessfully and also through my Windows 7 computer without success. Are there any tricks I can try or is this brand new card shot?
Thanks for any insight.
I can pretty much guarantee you have a fake card. Where did you purchase it from?

Really? It was working fine for over 2 weeks. I purchased it through buy.com from a third party seller. I doubt it.
Yeah sounds like a 2gb card hacked to read 32gb until you try filling it up past the 2gb. If you don't mind me asking, how much did you pay for it?

If you're right it had to be bigger than a 2gb because I had upwards of 9 gb on it when it was working. I paid $46.75 Here's the link http://www.buy.com/pr/product.aspx?sku=219375390
I've contacted Topram about a warranty replacement. I'll keep you posted on the outcome.

Topram is really not a very good brand. SanDisk is the only manufacturer that actually has a working 32gb card out right now.

i have a small question about sd cards, i have a sandisk 8gb class 4 sd card that i am using and i used the app SD Tools to test the speeds of my card and my results were as if the class of my card was higher than 4.....but i dont fully understand what speeds are for each class, from what i have read a class 4 should have 4mb of write speed, but mine ranges from 8-10 on the tests...does that mean my card is like a class 8 or 10?...if anyone could clear this up for me that would be awesome...ill put a screenshot of my test results if that would help also...

Soon as you receive the card, use H2testw 1.4 to test the card ( it will take some time ). If the card fails then contact the seller for a refund. If you have problems then open a dispute with Paypal ( hope you paid using Paypal ).
http://sosfakeflash.wordpress.com/2...standard-in-detecting-usb-counterfeit-drives/
The seller is top-rated 99.99%, I doubt it is fake.
I own this card and the image looks real. Ridicilously cheap though.

another method u can check and find out if the card is real or fake is if u download sd card tester from goople play and that will also tell u wether its a real card or a fake 1 by validating the write and reading speeds.
Well when it first came out (the tab s 8.4) only 128gb micro SD cards were the largest available.
So my question, can we assume that any micro SD XC 1 card will work fine in this tablet?
I ask because I stumbled upon this 200GB card now available.
http://www.amazon.com/SanDisk-micro..._UL160_SR160,160_&refRID=00EQDPJ5PMBTHB0A266Q
Or is this tabs card slot locked some how to only except up to 128GB max?
If the Tabs S works with XC 1 cards have an 128gb one and it works fine, I suppose an 200gb that is XC 1 should work as well as an guess.

Can anyone recommend a card with decent speed?
I'm using Sandisk 32 GB and the transfer speed sucks... avg around 10mb/s when transfering files from my tablet to PC via USB cable.
http://www.amazon.co.uk/SanDisk-MicroSDHC-Memory-Card-Frustration-Free/dp/B00422GXXA
Get the biggest card you can afford, a 64gb or 128gb, I only ever buy Samsung flash cards for years for my camera`s phones and tablets, I all do a exhaustive error test when i get them and i have never found an error or had one fail, So i don't have any experience of other brands but Sandisk is a good brand.
I just bought an Samsung 128GB Evo+ the other day for £36 and i am just about finishing the error testing, It is showing a write speed of 20.46mb/s and a read speed of 63.56mb/s these are just basic number using an USB 3.0 card reader on my notebook, I have an crystal disk mark test results if you want to see them.
My T800 10.5" has formated my Samsung 128GB EVO+ as ExFat file system, benchmarks should really be run with the card in your Tab S for real world results.
John.
Thanks! Time to test out Samsung sd cards then.
Highly recommended Samsung evo cards. Its all I use now. Good value for money.
A few speed test reviews on Amazon say the Samsung 128GB EVO+ is not very good as the 4K file write speed is very low, But i dont write anything that small, even ebook files or mp3 files are hundreds of mb/s

I personally never had any issues with Sandisk. I have really old Sandisk cards laying around (64mb) and they still work fine.
I'm actually scared to try a different brand with the good luck I have had with Sandisk.

I am in the US but this is what I am using now. The 32gig one. Go with the biggest you can afford to be honest. Make sure its class 10. Always buy from an official Sandisk seller on Amazon to avoid fakes.
