Hello,
I have a 8go storage for now but I'm getting close to be out of space (I have like 700mo left).
I would like to buy a 16go sd card but I'm not sure which one...
I have a nexus one rooted (with A2SD) so I don't really know what I should or shouldn't take. (because 20$ of difference between two "same" card is suspicious )
Could you help me ?
Best regards,

Sandisk is a reputable manufacturer, Kingston is another, but make sure you also use a reputable retailer so that you don't end up with a knock-off.
The Nexus One can't utilise speeds above Class 2 so unless you are planning on using the card in a dedicated card-reader a lot, or are thinking of future use, i wouldn't worry about spending premium amounts on faster cards.
min. class 4 is a must but you could look for class 6

Of course it can, delve into the 720p recording thread...
I found class 2 or class 10. Better go for a class 10 or it is not recommended ?

The speed from N1 to PC is not the same as the internal speed.

This is true. My PC transfer speed is insanely slow. Took over 6 hours to transfer 8GB of data (was re-partitioning and did not have my microsd adapter)
A 16GB class 4 chip should be about $30, unless you jump on a special deal.

Obviously, but transferring files is the only reason why you would need a faster card. With the N1 seemingly capped at low speeds..yadda,yadda,yadda...
No it's not.
Recording in HD will require a decent speed, running data/dalvik-cache off SD-EXT will require a decent speed (things are noticeably slower on my C4 when I do that).
I've used a Class 2, Class 4 and Class 6 card on my N1 without any noticeable difference. I've put a clock on metrics like app launch times without any difference in the results.
People who spend extra $$ on faster cards convince themselves that they notice a difference to justify their spend. I wanted my Class 6 to make an improvement in daily usage but it didn't. I have to put it in a card reader so that i get any benefit from it, and that's only justified for transferring large amounts of data as you have to consider the time needed to remove/replace the card.
so personal expierences = fact now?
because I notice a major difference between my class 2 and class 6 in my N1
so that makes a new fact now
Can we have some facts on this issue?
For example, is it faster to take pictures if you have a faster class speed?
Is it faster in executing tasks?
etc.
Anyone have any results?
I'm thinking of getting a class 10 microsd card for record 720p video.
So far I've used Kingmax 16GB Class 10 with no problem.
I just bought a Sandisk 32gb MicroSDHC Class 2, hope it will work fine with everything, need a lot of space for music
I'm using a Patriot 16GB Class 10. Overkill? Maybe - depends on who you ask. But if you're putting the system cache on the card and recording HD video, it certainly doesn't hurt.

r u sure it cant handle more than class 2 ? i am not sure, but think its matter of card , HW of N1 is speedygonzales
personaly i would look for something like:
since i cant post link:
ADATA Micro SD 32GB SDHC class 4
Speed (read) : 10~14 (MB/s)**
Speed (write) : 2~5 (MB/s)**
Speed Class : Class 4
its cheap , it worth a try
will i be able to use a class 4 micro sd card?
http://www.amazon.com/SanDisk-micro...2?s=electronics&ie=UTF8&qid=1304280254&sr=1-2
or would anyone recommend something different?
Any class will work. The higher the better. It will be faster. I have a 16gb kingston class 4 card and it works great.

"The higher the better"-that's a false statement, but if you want to get the best oud of the MicroSD, go for class 4 or class 6. Am currently using a class 4 8gb.

the fact it may not support as high a speed class as you can find.
for example my N1 would support a more expensive class 10 card but not at those speeds as the N1 was limited to i believe 4? so a class 4 is all you would need
Im not sure what our G2X supports but a class 6-8 should be fine

There are also quite a few tests out there that show many class 10s transferring slower than some 6s. I shopped around for a while on newegg, not many good things coming out of the 10s on that site. 16gb Adata 6 is what i settled for. If I end up needing something larger in the future, and I have the money, I probably would go with the 32gb Lexar class 10.
what's the cheapest anyone bought a 16gb from a reputable site/seller online? i'm eying the patriot 16gb on amazon for $25. 3rd party seller can be fake.
I have a 16gb Class 10. The statement higher the better is true. A class 10 vs a class 6 thats a difference in speed of 4mb.

Theoretically, that is the case. 10s are suppose to be faster. But that's the manufacturer's marketing that says such. In real world testing, they are not getting much faster speeds (or are actually slower) than some 4s and 6s.
Buyer beware.. do the research yourself and you'll find what I found. I wanted to get the best card for this phone.. and after much reading, I stayed away from the 10s.. Do some browsing on newegg and read the reviews on all their 10s.. it's not pretty.
I'm not sure about other SD cards but i have a class 6 on my N1 that while it worked it wasn't great when running some apps from it or when view lots of pix in the gallery.
with the G2X that isn't as much an issue, but can anyone recommend a fast 16gb card? hopefully fast enough to run apps from if i need it later on
I found a couple class 10s that had great reviews from other cellphone users and I chose one of those. (It's in the mail now.) Are you guys saying that our phone is limited to sub-10 speeds or that the cards themselves are not as good at higher classes? I thought the class rating was determined by the card's speed... if so, wouldn't a card that is slower than a class 6 be rated below 6 by definition?
The lower classes are considerably cheaper so if I bought something off, I need to know now!

I dont know for certain but I doubt the G2X supports class 10 speeds.
as far as cards being slower than the advertised rating, its just typical marketing. just like HP ratings, GHz clock speeds, Megapixels, Amps,watts, ect ect
The class speeds stamped on these cards are notoriously unreliable. The 16GB Class 2 card that came with my HD2 consistently beats my brand new Class 6 card on every benchmark I run. I recommend buying from a retailer with a decent return policy and benchmarking your new card to make sure your getting the speed you've paid for.
The other issue is at what speed the G2X's SD interface maxes out...and I've seen no data on that...
Do any of you guys have benchmark data on your SD cards in your G2x for whatever class card you have?
Guys heres how it works:
HAve you ever tried to put 8gb's of memory into a computer that only supports four?
Or a faster memory into a computer that only supports the later?
same thing if your phone doesnt support the class/speed/size its going to run like SHEEEot/slow/not at all!!
I have the class 4 16gb card and it works great. why spend money on something you dont need?

Are you using the class 10 card in your G2x? Are you getting legit class 10 speeds?
It looks like everybody in this thread is happy with class 4... anybody getting appropriate performance on higher class cards in their G2x?

I did on the Adata 16gb class 6.. It was reading at around 18 and writing at over 10. That was putting it up there w/ class 10 specs..
Manufacturers suggest using the SDFormatter V3 to format the card instead of using other utilities in the phone or windows.

I don't think anyone knows for certain what the phone is capable of. If you find that out, great.. please let us know.
What I'm trying to relay is that the speeds mentioned on class 10s are not what they are all cracked up to be. Sure, higher is better.. but it's only better if it actually achieves a higher speed. Also, it must be a higher speed that can justify the price difference. Beating a class4 by a cpl mb/s but double the costs was not worth it. I spent a few days doing research on this.. studying many different test results, etc. I could go back through and find all the data for ya.. but I don't have time. My final result was that the class 10s were not worth it.. they had a higher fail rate than the 4s and 6s.. they were less recommended/had lower reviews than the 4s and 6s.. in some cases, they performed slower or at par w/ a 4 or 6, and they were dbl the price. There was absolutely nothing that said it was a good route to go. Nothing outside of the marketing.. "Class 10!!!"
In some cases, depending upon manufacturer, you can find a class 4/6 that will outperform some class 10s. I also see a much lower customer satisfaction, malfunctioning cards, returns, etc. when it comes to the class 10s.. much more than any other class.
Hey guys, I just got my sensation yesterday! YAY So happy with it so far.
But can any of you guys recommend me which micro SD card is the best for sensation? I am looking to get 32GB.
I heard it will make the apps lag if the SD card is not very compatible with the phone? Any idea guys? Please help me. Thank you.
someone here mentioned that sensation only reads/writes upto class 4...so i guess it wouldn't really matter if u get a higher class
but u may end up using the card for something else like a camera. so it doesn't hurt to get a higher class
So what is the highest class available now? What brand do you recommend? Thanks for the reply!

i've had a class 2, 16GB sandisk for 2.5 years on my Touch Pro 2 with no problems at all.
I ordered this today. My 8GB is already half full after a day so I need bigger.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211519
I'd highly recommend the Lexar 32GB Class 10 card.

Complete rubbish.
The official specification for Class 10 is a read speed of 10MB/s and a write speed of 10MB/s.
The official specification for Class 4 is a read speed of 4MB/s and a write speed of 4MB/s.
(sorry if that was stating the obvious, but I don't think some people realise)
The benchmarks for my Lexar 32GB Class 10 card in my Sensation (using "SD Tool" from the Android Market) are a read speed of 21.4MB/s and a write speed of 8.3MB/s (taken from an average of 4 tests).
So the Sensation doesn't quite meet Class 10, but it's much faster than Class 4 and 6.

I use the card "Patriot 32Gb MicroSDHC 10 class" in my phone. Speed record over the phone - 10,5 Mb/s, reading speed - 18 Mb/s.
I am looking at either a Lexar or Samsung both class 10, both around £37.
any advise as to which one is best based on anyone using.
The other question is do you need to format before use?
At the moment I have a 16gb but it is 98% full. Never chenged a card before was planning to copy the old card into a folder on laptop and then back onto the new card.
Any advise welcome,,,,,,,,
Go with transcend. If they have 32gb class 10.
They only do a 16gb class 10. I looked for Transcend first as I prefer this brand.....

I like transcend more than anything else.
I never had luck with transcend, i have a sandisk 32 gig which works great,
i had a kingston 32 class 10 within a few weeks it just burnt out on me it stop reading and wouldnt want to format or anything
I'm also looking for a 32gb micro sdhc for my HTC Vogue. I currently have a Sandisk 16gb that is nearly full. Earlier today I stumbled onto this thread from here at XDA...
http://forum.xda-developers.com/showthread.php?t=1150369
I found it quite helpful. I hope you do too.
I was surprised that class 10 cards weren't the best choice for the things I use my Vogue for.
Here is a passage that surprised me...
"Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds.".
I would agree with Random read/write access might be better in Class 4 cards than Class 10...
But arent we forgetting that most of the applications are read more than Written when u open it.. I think a faster read speed with lower write speed would still be better than having lower read/write all together...Not unless you are downloading a torrent in background and running HD game with it... infact in that situation.. both cards will fail badly..
I prefer Sandisk.
A class 4 should generally give proper performance... 10 seems a bit overkill imho.
I've used the 8GB class 4 memory card that came with the Sensation for a while, and after switching to a 32GB class 10 Lexar I must say - it DOES make a difference. It's a totally different experience.
Been using SAMSUNG ESSENTIAL 32GB MicroSD for more than 2 months without issues. It has helped me to parallely download videos from tubemate in high speeds. Good writing and reading speeds. No slowdowns/jatter in 1080P recording which iam always using to cap my child.
Just bought a 32GB Class 10 Samsung card from play.com for £34.99. Working great so far!
I got the 16GB SD card for two reasons
1. The 16GB has a faster write speed.
2. I didn't have $90 to spend on the 32GB.

Oh also I did not pat $55 for the 16GB

My 8GB Memory Card in my Sensation XE if almost full now, and i plan to upgrade to a 16 GB MMC. I know that Class 4,6 and 10 have Read/Write speed or 4/6/10 MB/s respectively on the computer.
I want to know, how does these different classes affect when running in a phone except the obvious copying files thing.
Thanx in advance.
I believe as you said that the same holds true for the device. It has to do with the speed. I also just upgraded myself to a 32 . This is the first time I've used a 32. But I only have a class 4 ( same class that came with the device) as I really couldn't afford the higher class at this point. I've had no problems so far and it seems to be working well. I would like in the future to obtain a higher class and see the difference for myself.as I also wonder what kind of differences it will make on our device. Best wishes to you!

no budget stated so i'd say go for sandisk 64gb sdxc.
Have one right in my sensation for a few weeks already
back in my htc magic days, i was always told class 4 = too slow, class 6 = perfect, class 10 = too fast (yea, too fast)
of course android came a long way since then but i got myself a class 6 anyway
Well, I don't know if it is the same for micro sd's but in my GoPro I have a class 10 32gb SD card previously having a class 4. I would say that since I have upgraded to a class 10 my copying speeds to and from my camera have halved and the footage that I get seems to be of a higher quality. So I would say get the highest class you can afford. Hope that helped!
The difference in speed is VERY noticeable when taking pictures on a class 6 card compared to a class 4 card. There's very little delay when the picture is saved.
Class 6 was well worth the money in my opinion.
Edit: oh, and also, there's no lag when playing high bitrate video.

I think i am gonna go with "Transcend Memory Card MicroSDHC 16GB Class 10". I'm gonna order it and will post what difference i notice ! :highfive:
your posts really helped
i read in the official sd site that in order to achieve optimal performance you must match the speed class of the card with the one of the card reader. for instance, if the sensation's card reader is rated class 4 faster cards will provide no benefit -- and a few drawbacks, too. the problem is getting to know what class the sensation's card reader is mounting
Class 10 is usually optimised for digital photography/video where small numbers of very large files are written. Smartphones read and write hundreds or thousands of small files and hence might preform better, as the card fills up with a class 6.
Having said that I doubt anyone would be able to really notice the difference in real life...
Also, go for at least the 32gb card, price difference is usually tiny and you'll take a while to fill the larger card.

I don't know how its where you are but where i am, i see that Transcend 16GB class 10 is Rs.885 / $16 / GBP 10 and the 32 GB Transcend Class 4 is Rs.1400 /GBP 16/ $ 25 so it kinda gets expensive.
There is one from a brand called 'Strontium'...the class 10 is cheaper than Transcend Class 4......32 gigs. But have you heard the name before ? i havn't...

well, if there is no means to figure the reader's speed out, i would not waste money on a class 10 and play it safe with a class 6 or 4. at the end of the day i am no speed / stats / benchmark freak, and prefer to solve actual problems rather than having the fastest stuff available. i'd take the most stressful task in real life (namely: playing 1080p video without hiccups) and then opt for the cheapest card that handles it without a flaw
I have a Sandisk Extreme Pro 16GB card on my sensation. Really have much greater speeds when transferring data between PC and card. My nandroid backups used to take about 300 seconds with class 4 card, which have come down to about 150-160 seconds with new one. Also I'm using hard swap, which benefits using a higher speed memory

Okay, Thank you
Btw...what is hard swap ?
If you root your phone then go for class 10.
But if you stay on stock rom there is no need for fastrr then class 6.
I do not know the price difference (where you are buying) but I think for everyday usage you will not notice the difference.
