Hello,
Now that Froyo more or less came out and apps will start having Apps2SD function, it's time for a MicroSD upgrade.
What I want is on-phone performance - that running heavy 3D games on SD would perform as smoothly as if it was on internal memory. Is there a general consensus on what brand/class would suffice, and what is overkill? I have no concern over data cable transfer speed, as I'm pretty sure the phone will limit the speed much before the SD card does.
I'm looking at this Sandisk 16gb MicroSDHC Class 2 for $35 after shipping:
http://www.amazon.com/SanDisk-Flash...ref=sr_1_1?ie=UTF8&s=pc&qid=1275145563&sr=1-1
Anyone know if this would suffice?
Past threads have always went on tangents about good brand vs knock offs, how class is important vs. a marketing ploy, etc etc. Has a general consensus been reached in the xda community over what is sufficient but not overkill for onboard performance? Perhaps people who have already ran App2SD and use games and videos a lot have some input.
Thanks
I have a Top Ram 16 Gig class 6 and I think I paid about the same as you looking to pay for a class2. I also have a class2 that I have had for over a year. I used to use it in my blackberry. It still works and it is made by one of the cheap manufacturers.
Argh, I'm suffering from chronic SD corruption. So I'm in the market for a new chip. Think I'll spring for a 32gb this time. What's the latest on one that's both compatible and fast? And cheap too, that would be nice, links appreciated.
Considering that due to the amount of RAM the N1 has your main apps will be loaded already so card speed is not a significant factor, unless you use lots of different apps on a regular basis.
A faster card is beneficial mostly for the time i takes when I am loading up new music and possibly vids if you use it for that
This is the first 32gb MicroSD card I have seen "In Stock" Pretty expensive for a class 2 though.

Im not sure the nexus 1 can handle a 32GB card , wow that's a lot lol, but you can get one for like $30 on ebay... http://bit.ly/9J7u2S
You can get a 16gb class 10 for about $90.00.

Micro SDHC is a standard that supports up to 32gb. Of course it can handle it just fine.
I run a 16gb Class 6 in mine, works fine
bewar ebay, there a lot of folks selling fake cards. They even read as what they were sold as but then fill up mighty quick............
The class is not needed I don't think
I have a class six and have been running games on it from sd for 3 months cant tell a bit of difference. I run linpack from sd and it works fine too!
the only real 32gb card is found here., http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc

I'm running a 32gb Sandisk Class 2 in my Nexus as of last Friday. No problems (apart from a looooong time to refresh the media library after resyncing my music).
You can not get a genuine 32GB Micro SD card for US$40.
A good class 2 card (2MB/s) will offer you the same performance as any other class in your phone.
The limitation is not the speed of the card.
Buy a brand name card with the capacity you require and be done with the complexity.

I don't know too much about transfer rates but basically what you're saying is that a a brand name class 2 card will be just as good as say a class 6? I'm in the market for a new SD card as well, and the class 6 cards are much more expensive. I'm wondering if they're worth it.

No, in a phone they're not worth it at all and people who say so are either selling snake oil or are embarrassed because they've paid for one and are foolish for doing so.
The best I can do just at the moment is this:
wikipedia said:
In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media.
Click to expand...
Click to collapse
The Nexus, like probably every other phone out there, is a) not typically used for high rate sustained write activities and b) is designed to write to class 2 media to begin with.
If you have a large, highly fragmented sd card higher speeds will help. This of course is easy to avoid in the first place.
Get a higher capacity, class 2, brand name card for the same money and you're away laughing.
NB - If somebody waves a magic wand and all of a sudden the Nexus can record video at 1080p at a high enough bitrate then perhaps my advice would be invalidated... but don't hold your breath for that to happen...

Thanks for the info man! I was obviously misinformed, you just saved me a bunch of money
so just curious. now that CM 5.0.8 comes with 720p recording, would a class 2 still suffice?
I am also searching the web recently to look for a cost-effective high vol microSD. My finding is: don't 100% trust the "class" specified by mfr. I used ATTO Disk Benchmark to test two 8G microSD that I have: Transcend 8G Class 6 and Sandisk 8G Class 4.
<Transcend Class6> Write: 6-10MB/s Read: 16MB/s
<Sandisk Class 4> Write: 14MB/s Read: 20MB/s
From similar test results on the web, it seems that Sandisk uses to under-state the performance of their card. Finally I get a Sandisk 16G Class 2 for my N1, and here is the test result with the same setting:
<Sandisk 16G Class2> Write: 7MB/s Read: 20MB/s
Although Sandisk only specifies it as class 2, it actually performs like a class 6.
I suspect the importance of the speed of the SD card too, coz I think the write speed into ROM, should be way slower than 6-7MB/s (correct me if I am wrong ^_^)... If the speed of v2.1 w/o app2sd is acceptable to you, then v2.2 with 6-7M write speed card should be logically fine with you.

huh that's interesting. i just might pick that up from amazon then..
I Dont think fragmentation makes any difference to write speed, these are not mechanical devices like hard disks.
Also defragging is pointless and shortens the life of the card by increasing the number of writes.
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,
rXp>!<
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

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
Been looking around for which microsd card to replace my venue pro one with. definitely want a 32gb one. Pulled up a few, are a lot of people having problems with the class 4 cards? Should I stick with a class 2, even though the 4 is about the same price, or cheaper? Here are the few I found, all around $80. Price doesn't matter, just want the one that will work the best.

I'm 100% sure someone had posted the 32GB MicroSD card S/N they use. I don't remember which post it was, it is somewhere in the Venue Pro General form.
I think class 6 should work. Max Miller at ZDNet has posted a blog about how he swapped a troublesome dvp's 8gb card with 32gb n the dvp is working like a charm after that. It has a video aswell.
Sent from my Venue Pro using Board Express
Whats the largest SD card Windows mobile 7 can handle, and if it's less than 128 will it be able to recognize "partitioned" SD cards?
I use a sandisk 32g class 2 and it works fine. Did find a lot of class 4 of same price but skipped as I only saw that class 2 works from posts online.
And from a random (not sure if reliable though) article online, it says WP7's file system depends on random I/O seek time (or alike) which is a different dimension from class, which gauge the continuous transfer speed.

Why would a slower class work better than a faster class of SD? Class ten is the fastest your able to buy.
If I can buy a class 10 32gb would it work?
http://www.newegg.ca/Product/Produc...61411-L06D&AID=10657534&PID=749547&SID=forums
I swapped my 8GB class 4 that came with the device to a 32 GB SanDisk class 4. I do notice slower write speeds - 720p video in particular seems to have a lag when capturing. Other than that, the phone is zippy fast.
I bought a Dell Venue Pro (normally hate Dell and don't give them the time of day) and from what i've been reading i'm going to be stuck with a class 2 or 4 (32gb) MicroSD card. And to narrow it down even further supposedly the ones that work best with these phones are sandisk.
So my questions are this. Will I actually be able to use a class 10 microsd card or is it a limitation of the physical phone. I mean windows is capable of 32gb and probably more.
If it isn't able to use class 10 right now will there be a firmware update for the phone that will allow it.
What would happen if i bought a kingston or patriot over sandisk (as i've always considered them the bottom of the pile)
I've been using a 32gb sandisk (class 2) for a couple days now and it's awesome. Despite being class 2, it's way faster than the crappy class 4 that came with the phone.
Random r/w speed is the most important thing to worry about with WP7 devices. Class rating does not say anything at all about random r/w speed, just about the maximum throughput. In fact, there is often a NEGATIVE correlation between class rating and random r/w speed - the higher the class, the lower random r/w.
So that's why class 2, 4, or 6 cards seem to be the best.
so could anyone give me a link of the best 32 gb sd card I can use for my DVP that would be awesome.
the one that came with my phone is starting to fail (constantly getting the black screen with memory card problem and asking me to change cards and reset)
another question
let's say something happens with my phone and I need to send it back for warranty repair, could I possibly switch out the sd card back to the original one, reset and be ok?
So does this phone have a SD card that is expandable? I just got the phone a week ago and thought it was built in and couldn't be changed.
Hi all,
What is the maximum capacity Micro SD card size on the TF and also, what Class type do I need?
Thanks in advance
32 gb has always been the limit.
OK thanks, but what 'class' type? I see class 4 and 10 advertised?
well the class is the write speed of the card. The higher the number the faster the speed with 10 being the fastest. I use a class 4 that i had from my thunderbolt and that works just fine
Dont think it matters what class, it's just the write speed of the sd card.
And what all can you use this SD memory for?
Class just specifies the maximum write speed, but with day to day use in the transformer (other than transferring the initial media) it's the read speed that's the most important. You''ll be storing and opening your media from it (music, pictures, videos and PDFs or other e-reader formats most often). Usually a card with fast write will have fast read speeds as well but there can be some anomalies with certain cards so it's not always so clear cut. In my experience anything above a class 4 seems to work just fine. If you're working with a lot of larger video files though probably class 6 or above would be better (and as it's also a little more future-proofed). I would always prefer to go with a named brand class 4 or 6 rather than a non branded class 10 though.

Even that isn't the whole story because it's incomplete - the class of the card minimum sustained write speed of the card under optimal conditions (i.e. a brand new and completely unfragmented card). I'm sure someone else can improve on that definition further!
As to what speed of card you need, from sdcard.org:
Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording
Class 4: MEPG-2 (HDTV) video recording, digital still camera (DSC) consecutive photo shooting
Class 6: Mega-pixel DSC consecutive photo shooting, professional video camera
Class 10: Full HD video recording, HD still picture consecutive shooting
Planning on doing any of these with your TF?
I've been using good quality Sandisk Class 2 cards in all my Android devices since the original T-Mobile G1, and *never* had an issue with them. Plus when testing, I usually get a write speed of around 7.5MB/s.
Regards,
Dave
I use a class 4 16gb and its fine. No problems. I think the faster classes are over rated. I typically try to find a class 4 or 6. Both work great. Don't waste your money.
You can get a 16gb for about $25 and a 32gb for around $40

FAssuming Asus implemented SD 2.0 standard, a 32 GB maximum storage capacity is your limit for any SDHC memory card. You can read more about it here: link.
As for which class you buy, it depends on what you're using the memory card for. Foxmeister answered with a class rating list. Do note that the higher the class rating, the more expensive the memory card is. Like wise with storage capacity. I recently bought my PNY 32 GB microSDHC class 10 memory card from buy.com for about $57. Caveat emptor with fake ones on eBay, especially ones shipping from China.

yep, picked up one of those "fakes on eBay". That really stunk.
I am going to buy myself a 64GB micro sd card. I guess I will go with sandisk. But as there are certain sd types there come certain speeds. Such as UHS-ll, UHS-I ,and microSDXC. Now I want to make sure that my phone (SM-G3858) Galaxy Beam 2 is able to do r/w at certain speed levels. But how can I determine that? How can I check if the sd card slot takes UHS-I? I can do a micro sd card speed check when I already bought the sd card (with some apps). But is there any way to check the speed compability BEFORE you even buy the sd card?
I did 3 speeds test on my kingston 18GB MicroSDHC/SDHC Class 10 and the sd benchmark tests were ranging from (max): Read 401,31MB/s Write 10,45MB/s (400 seemed a lot to me, but thats what it said) So that would mean my phone supports at least UHS-l?
I was thinking to buy either the Sandisk Extreme at 45r/45w, the Sandisk Ultra Plus at 40r/lower write or the Sandisk Ultra at 30r/lower write. Or should I go with another brand? Any help is appreciated
thanks
:good:
EDIT: After searching for several hours to find the best 64GB micro sd card I decided to go for the Samsung Evo 64GB. It has full 5 star reviews on amazon and the price was way better than the Sandisk extreme plus. (I paid 37 euros including shipping) This is the best review I found:
"This is a very fast card, particularly suited to not only transferring files quickly but also running as a phone or tablet card for applications as well.
In phones and tablets one of the most important things is not just the transfer speed but also the IOPs that the card can deliver. Many class 10 cards have great transfer speeds but terrible and I mean terrible IOPs, often a 5 year old card easily out performs them in IOPs.
This card delivers in both areas, fast class 10 transfer speeds 23mb read, 15mb write but also 482 write IOPs and 1668 read IOPs.
That's IOP speeds that are slower than an SSD but way faster than a hard disk. Bare in mind that some class 10 cards give 4 write IOPs and you can see why I'm impressed. The only card I have seen outperform it in IOPs it the SanDisk Extreme Pro and they are seriously expensive and not available in 64gb. Testing against the third SanDisk I have, a 32gb ultra, is almost funny as the ultra only gives 15 write IOPs under the same conditions, making this card 30 times faster.
What does this mean for normal use, well it translates into an excellent general purpose card, that even if it doesn't have the official fastest transfer speeds will actually perform much better in the real world. Which is why its getting such rave reviews on here for speed (so long as you get a genuine one!)
This was tested in my Dell Venue 8 tablet using the built in card reader. For the techies (if you've got this far then I assume you are)I am actually using it to run Server 2012 virtual machines in VMWare workstation and the performance is surprisingly good, I would even call it snappy!
Full Crystalmark disk scores below.
Sequential read 23.66mbs write 16.03 mbps
512kb random read 23.25mbs write 15.67 mbps
4k random read 6.40mbps write 1.850 mbps
4k random qd32 6.65mbs write 1.92 mbps
Parameters 5 iterations 1000mb sample size.
Tested on the 64gb Samsung Evo microsdhc."
So anyways..At one point I´ll wait until the price of the Sandisk 128 GB Ultra plus card drops, then check for benchmarks and try out that one. Enjoy the info, im off
Sandisk is having quality issues with 64Gb cards, with many consumers reporting dead cards in a few months.
The Samsung you have choosen is awesome, along with transcend which are rock solid.
