I hope I posted this in the right section, I wasn't sure where a question about MicroSDHC cards would go here.
By the way, I live in the US.
I have been Googling this for days now, and coulden't find any conclusive information, especially since most of it was from random tech blogs and not respected tech/research sites.
I am looking to buy two MicroSDHC cards to use in a Photofast CR-5400 ( http://www.amazon.com/PhotoFast-CR-5400-MicroSD-Adapter-Dual/dp/B001I0T92Q ), speed and performance are pretty important as I will he handling a lot of data through it.
First of all before I start, anybody familiar with this adapter? Where would be the best place to purchase one so I don't wind up with a Hong-Kong bootleg? Ive had trouble purchasing flash memory online before from places like Amazon or Ebay where the memory was a bootleg that didn't perform anything like the real thing.
Now, I know that Memory Stick Pro DUO devices are generally faster than SD or SDHC devices, but AFAIK that device sets them up in a RAID 0 configuration so I am hoping that will help, this is why im trying to get the best performance MicroSDHC cards I can afford. And trying to get reliable information on these things has been a lesson in confusion.
First of all, it almost seems like the class speeds don't matter. Ive seen benchmarks that showed class 4 or class 2 cards outperform a class 6. Whats the point of these classes if they are so meaningless? How can a class 2 device have faster write speeds than a class 6? And is this classification only for writing or reading too? Why are the "ultra" models of some cards, which are supposed to be very high speed, listed as class 4?
Second, I heard that there are other variables that usually are not listed anywhere, such as Random Access Times, which from what I read are internal processes taking place in the card itself rather than having anything to do with the card reading/writing to whatever it is plugged into. And I really have no idea what else could be a factor.
I was looking at THIS Transcend card ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208475 ) mainly because the previous 8GB version ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453 ) seems to be the best one you can possibly get, the 8GB model is class 6, rated as very high speed, and even has a low Random Access Time. But that doesn't mean that just because the previous model was good, the next one will be of the same quality, and on top of that I don't know if it'll even matter in that Photofast adapter or not. Not to mention its kinda pricey, don't forget that I will need to buy two as well as the adapter (though since the 16GB Memory Sticks came out at over $200 and they are barely around $100 now, and the 32GB still isn't out yet, I am going to assume it will still be at least $50 cheaper than just buying a 32GB Memory Stick............ when they come out).
So what would you recommend I do? Where can I find information that makes sense of this? Where can I find good benchmarks/testing done on these cards that on top of speed measures the other factors as well? Where would be the best place in the US, retail or online, to purchase such a 16GB MicroSDHC card for the best price?
Thank you for your time.
what are you using the Memory card for? (what application, video/photo taking, loading applications...)
Class X just says the minimum write speeds on an empty(defragmented) card... 2 means 2MB/s write, 4 means 4MB/s etc...
some SDHC cards also come with another rating... 133x that says max 20MB/s speed, depending on the manufacturer, that may be write or read speed
best place to buy is directly from Newegg/Tigerdirect, or from Amazon fulfilled by Amazon itself or a reputable merchant

Patriot 8gb class 4- very slow from pc to card ???
Anyone having any current luck with Patriot 8GB Class 4 micro sd's?
I copied everything from my PNY 2GB to my netbook. Very quick as expected...
Formatted the Patriot FAT32. Tried to copy back to the 8GB from the netbook and it was painfully slow. So slow it is not usable.
Both pc and Tilt recognizes the Patriot as 8gb.
Anyone having similar problems or any suggestions?
Possible formatting issue... No more Patriot SDHC.
I think I got it...
Took about 12-15 minutes to copy back to card.
It appears to be a formatting problem with the XP fomatting.
Used this... http://www.sdcard.org/consumers/formatter/
Tried the Wife's new HP laptop (school issued) last night and had the same problem. That pointed me to a possible card issue.
Moral of the story- google is your friend.
Just to be safe, I would stay away from Patriot's 8GB C4 cards.
I would just try another brand of microsd card. Sandisk are reputable but usually the most expensive, though on amazon 8gb cards can be had for less than 20 bucks. Kingston is another good brand.
Hello!
I want to buy new microSDHC card to my phone and I'm wondering which one is the best.
There are three priorities for me:
- SDHC
- 4GB
- minimum class 6
I found TRANSCEND microSDHC 4GB Class 6 and SILICON POWER 4GB microSDHC CLASS 6. Which one is better? Or maybe you advice something else?
THere is a lot of disscussion about this in this forum. Please search
Sometimes it's hard to find sth when does not speak the native english. Can you please give me the link to this discussion or just post the answer?

Thanks! I've already studied thread nr 1 and 3 and nothing special there. Number 2 is 16GB and 32GB - I need just 4GB and not for WM but for Linux (ext4 and maybe one fat32 partition on it).
well if it's a pda device then it's interface cant keep up with even the normal card speeds
so high speed cards only really matter when you have it connected to a card reader connected to a computer

So it's better to buy class 4 but 8GB that 4GB class 6?
i have not seen any difference personally between 4 & 6. so go for highest capacity.
i have used quite a few brands and all my cards now are sandisk. None of them have given me a problem.
most important thimg regarding performance is to make sure that its genunine. more than 85% of cards sold these days are duplicate.

I don't know jack about linux or 'rooting' onto an sd card, but if I were going to do it, I would make sure that I got the highest quality card available. I've corrupted my 16 G card too many times (mostly my fault, lol) to trust it for running linux off of it. Get something hardy that won't become corrupted, like if the device freezes and you need to reset it. My guess is that you're better off with a smaller card (like the 4 GB one). I'd stay away from a big one if you don't need it.
Basically, it's a huge PITA when your card becomes hopelessly corrupted and you need to back it up and re-format it. I imagine it's a nightmare when your operating system is running off of said card when it becomes corrupted.

That's right!
"most important thimg regarding performance is to make sure that its genunine. more than 85% of cards sold these days are duplicate."
what do you mean? TRANSCEND and SILICON POWER are genuine?
on my purpose,there ARE differences between class 4 and class 6 ,but there are to small differences in speed to pay the double price...I just using class2 Devices (on 3 PDA Phones,2 NDS and an PSP),i never felt there are to slow,yeah on PSP you really fell the difference between an MemoryStick Pro MkII and an Class2 Toshiba MicroSDHC,but for me personally it does not matter -the most of People buy Great Capacity Drives for Media Files right ? ....and Media Files like Movies,Mp3´s etc. running well on Class2 Cards!
Excuse me to say that...but SanDisk Sucks!
a lot of the Sandisk card have Chips from China
(i Don´t know on Class 4 or 6 Cards,but Class2 Card from Sandisk always have Chinese Chips....and there bullsh...)
Japanese Chips (like Cards from Kingston and Toshiba) are a lot better on speed and are a lot more reliable than Chinese Chips
I made my Experiences ,never by SanDisk....
just every Media Market have SanDisk- but that doesn´t mean there are really good..
I have Cards from Siemens,SanDisk,Kingston,Nokia,Toshiba and Motorola (Nokia,Siemens and Motorola are OEM- so i don´t know who produced them)) I have over 20! Cards between 64mb and 16gb---yeah and San Disk are the worst ..dood!
and there IS a Difference between Class4 and 6 Cards,but i think personally there are to less to pay the double Price for it
I have 3 PDA ,2 NDS and an PSP,all of them has Class 2 Cards and i never felt that there are to slow...most of the Devices on the market are to slow to feel the REAL Power of an Class6 Card!
I'm looking to upgrade the crummy 1GB SD card in my wife's TP2 to something faster. I was wondering if buying a class 10 card was worth it or if I should just stick with a class 6 or lower. Does the SD slot in the TP2 even support a class 10 card? Would a class 10 card be noticeably faster than a class6?
Not for this project. IIRC Nate said class 4 seems to be the sweet spot, the higher the class the worse it would be running XDandroid, but even some class 4's work better than others. Walmart has 16G class 4 sandisks for around $20, not too bad if you ask me

C10 cards are supported, but some have had issues. I would not recommend a C10 card for Android use. I doubt the phone itself will be any faster...

Cool. Thanks. So get a class 4 then? Is it worth it to get a 16 over a 8GB? My wife doesn't put much on her phone really and she streams all of her music.
Yeah I've got a Patriot 16Gig Class10 SD card that I picked up on sale months ago. I have been running XDAndroid on it since then and haven't noticed any benefit over my old 4gig class 2 card.
Not sure if it's related to running andriod but at first I was having issues with the card corrupting and losing all data on it, having to format it to be usable again. Formatting a few times with the HP tool seems to be helping.
I had a similar issue with my last phone (HTC Hermes) which would only work with good quality (Sandisk) SD cars, and failed with cheap chinese flash memory. The issue was that the phone wasn't able to remount the card properly in winmo when coming out of sleep, and the filesystem would become corrupt pretty quickly with folders disappearing and files having wacky filenames. Sounded like it was more of a hardware issue than anything.

Yea I use a class 4 card. Some have reported oddness with class 6, so it seems like the type of card matters as well... Because others with C6 cards say they work just fine. I've even had some people say C10 cards are fine, but most seem to have issues with C10 cards. Don't get some cheap knockoff, get a name brand.
As for size, that's entirely up to you. You can have up to a 32gb card. 512mb minimum .

I have a Patriot 16GB C10 card here too, but I no longer use it. It was constantly getting corrupted, the kernel logs were filled with I/O error messages. I'm now on a Sandisk 32GB C4 card and no more problems.

Just don't get a C10 card... I think that's what people should take away from this.
Some have said C10 cards are fine, but most say they are not. A few have had issues with C6 cards, but most say those are OK. I've never heard of people complaining about C4 or below cards - hence the reason I recommend anything C4 or less.
c10 sd android
My company name is WinDroidz and all I do is mod android and windows devices... and I have always seen huge performance gains with c10 cards, c2 sucks major, its just the transfer speed the card can move data at and clearly more speed no matter how u look at it with an SD card. Is crucial... I always used patriot c10, or topram and pqi c6 cards for android SD on windows devices and have only seen a posative result.. this is based on my personal experience of Modding more Devices then I can remember.... not from what I read somewhere or was told by someone... SD card data transfer is the slowest method of data transfer of all other common used methods... there are graphs if u Google it that show sdhc c2 cards lined up against other transfer methods like USB, ide, sata etc..... to put in perspective how ridiculously slow SD cards really are, once u see that u will understand why your phones drags ass so much when trying to pull up gallery after cache has been wiped if you have a ton of pics etc.... so if u are having problems with a higher class SD its probly not the SD and is something else you are doing, or maybe the brand as I can only vouch for the ones I've used... (wouldn't care personally about brand as pretty much everything is same manufacturer with restamped brand and packaging.. Kingston is Japan... currently using a c4 Kingston 32gb in my desire HD (wish it was a c10 but kinda pricey for that size and brand) I recommend c10 8gb for $30 on Amazon if u are using some kind of android SD rom.. or any device if u want better transfer speeds and it is very noticeable... no matter what speed u get though it will never run like nand android.. like HD2. So lets just hope the nand development for other devices continues like clk or magldr did for hd2 cause the hd2 with clk and full rom manager support is amazing
16GB class 10
Using 16GB class 10 and have had no problems related to the card, with FRX07.
I personally cannot think of any logical reason why a class 10 card of good quality should ever be a problem.
I just installed and ran Angry Birds Rio. It is slow, but works. Kind of fun to play in slow-mo!
i use 8gb c6 and haven't had any problem so far.
My 16GB RiDATA Class 6 Micro SD has been great, no problems.
Does anyone know for sure if this phone is compatible with 64gb microsdxc cards. I need more storage and there are reports of these cards working with a lot of android handsets. I'd love to use my phone with a 64 gig card but if not I might have a reason to upgrade to a S2.
nope, max it can take is 32
no chance man
@bortak: is there any proof or is it just according to the official htc specs of the desire?
my opinion is: we can't tell unless somebody bought a 64gb microsdxc and put it physically in a htc desire to see what happens. until then i am not willing to loose my hope ;-)
greetings from a tropical paradise
peter
well theres no proof but for sure you can try it but who want to buy a 64gb card if it probably wont work with the device? and why should htc give wrong specs to us(the customers)?
In my opinion are 32gb more then enough, if someone want to try it with the 64gb card, just try it!

Far as I know NO known devices even support SDXC so.. there you go
These 64GB sdxc still aren't widespread are not compatible with sdhc devices.
The HTC Desire does not accept SDXC cards.
@bortak and crimnous: just check this link http://www.androidnz.net/2011/09/sandisk-64gb-micro-sdxc-cards-confirmed.html
@loler90: for instance in germany you can place an order at every (german) internetshop and you always have the right to open and test the goods and return it within 14days or a month (i do not remember exactly) without any reason. your money is refunded completely if the value of the product is above 40 euros otherwise you pay the shipping costs. so i could imagine someone give it a try without the risk of loosing 160 euros which is the current price of a 64gb microsdxc on the german market.
greetings
peter
@peter_altherr iknow it, i am german, but it sucks if you have to go to the shop again to give it back
anyways the package of the sd card sucks
Fact: Desire supports only SDHC cards. End of story.
terepin, have you already tried it (reformat a microsdxc to fat32 and put it into a desire), so you can say fact?

I would be wary of using a SDXC card long term even if it works at first. My Lexar 32GB SDHC Class 10 worked fine for a couple of weeks in my HD2 utilising a 1GB EXT3 for apps, but then corruptions crept in on the EXT3 partition. Even after a reformat/reset of the phone, a couple of weeks later the same thing happened.
I spoke to HTC who reckoned that class 4 is supported on HTC phones but no higher. Something to do with access times being slow as the pay off for high transfer speeds, thus corruption occurred since the HD2 was not handling the slow access times appropriately.
So, an SDXC may appear to work but you better make sure you have a good backup regime in place that doesn't rely on the SDXC at least until it has proved itself over some considerable time.
Meanwhile my class 10 SDHC is now working perfectly happily in my Xoom tab.
this explanation sounds really strange to me, sorry.

Maybe it sounds clearer if I put it like this:
Either Lexar's implementation of the Class 10 standard, or the Class 10 standard itself is not supported by the HTC HD2, according to HTC Customer Support. A year ago they told me this - it may have changed for newer models but that was their stance back then. The HD2 & Desire are likely to share some common hardware regarding SD cards cos they were release quite close together.
In my practical experience, the Lexar Class 10 32GB microSDHC, using a 1GB EXT3 partition with the rest in FAT32, apparently worked fine for a couple of weeks. Then the HD2 failed needing a reinstallation of the ROM/EXT.
After this reinstallation, it happened again after a couple of weeks.
Since using a Sandisk 16GB Class 2 with 1GB EXT3 & the rest in FAT32, & the same ROM, the problem did not repeat.
I am awaiting delivery of my Sandisk 32GB Class 4 which will be similarly configured & I am confident it will be fine too.
What makes me wary of the idea of using a SDXC in an "unsupported" device is that incompatability may not show immediately - it may take some time in use to corrupt something vital to the operation of the device (eg. apps on an EXT) or your data.
Just saying - take care!
incompatibilities between certain sdcards and controllers in cardreaders are nothing new they exist since those devices are existing. I would not blame it to the class10 standard which in reality is no standard itself it is a part of the sdhc standard. classXX defines just a speed class guaranteeing you certain permanent read/write data rates.
i fully agree with the rest of your comment. operating something out of its specs requires special attention.

I know I'm dragging up an old thread but thought you may like to know. I've been running an sdxc card in my Desire for a few months now and all is well. The card is nearly full and working fine with an EXT4 partition for apps. I've found some implementations of apps2sd+ can be a bit temperamental but the version in Mildwild Oxygen is working fine
The only thing I had to do was reformat the card to fat32. I've no longer needed to carry an iPod and happy that I can transfer the card to a new phone when I move on

It was a Sandisk from Amazon. I would guess Sandisk have probably changed the card since mind as I'd got it when they were first released. I did find it had problems when formatted in exfat on my S3 but it worked fine formatting back to fat32. Sandisk apparently fixed this in later versions.

I'm afraid that my Hydrogen is killing SIM cards of the german provider "Netzclub" (O2). Two cards died already after about two months of use. It started with frequent loss of signal, then permanantly no signal and in the end the SIM was not even detected anymore.
On the phone I am running latest Lineage OS.
It sounds pretty much like the problems with Oneplus devices and Fairphone2 killing SIM cards due to a bug with processing the MEC-request (mobile equioment change) that leads to a loop of continous read/write actions to the card.
Anybody having similar issues?
i have the same problem with my kenzo/lineage bzw.
kenzo/mokee.
my sim card is from t-mobile.
i think it's a problem with lineage.

Get me radio log when phone talks to one of those affected sim cards and I'll see what can be done to fix it.... If it is a firmware problem then it's up to Xiaomi. And probably is b/c affected devices runs all kinds of different android flavors. It is not Lineage problem, might be AOSP problem but I doubt it...

I have had my max for a couple of months with no issues running both sim slots is this just affecting rooted users?
No issues with mine, been using this phone for more than six months and the SIM card is fine. It's a micro-SIM, not a nano unit.
On the other hand, my Sandisk 128 GB card failed completely after a few days of slow writes. I don't know if it's a bad batch or if the phone got too hot, too often - I've seen battery temps around 45 C and CPU temps near 60 C when charging at 2400 mA on a QC2 charger.

I also had a 128GB Sandisk fail in less than a year, I'm pretty sure the 128's were just a bad card. I'm on a 200GB Sandisk currently without issue. Think I'll stick to Samsung memory in future!

Agreed, probably a bad batch. I had it fail while traveling, luckily I could still read the card and most of my files were fine. Thank goodness for cloud backups...
I got a 64 GB Samsung Evo Plus card as a replacement , apparently they got good reviews for being fast and cheap. I also have a portable hard disk that works with the phone when connected to a powered USB hub. You can't trust cheap flash drives to be reliable.
