MicroSD for Froyo - general consensus?

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.

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.

[Q] MicroSD Card

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.

http://www.amazon.com/gp/product/B004G60AD6/ref=olp_product_details?ie=UTF8&me=&seller=

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.

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.

[Q] what class of micro SD card does this phone use

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?

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.

32gb MicroSD advice please

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 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

Which microSD card for Honor 6?

Hello,
I apologize if this question has already been made but I have a little concerns regarding this matter.
I recently bought the Honor 6 online and I'll receive it soon. I'd like some advice for buying a microSD card that meets my needs.
I'd like to buy a 64gb card that is fast enough (mainly for music and also apps), so I'd avoid cheap cards (unless you assure they're more than ok).
I've made some researches and I'm a bit confused about few points.
What do I really need to check in a card? Is it true that for mobiles the most important thing to see in a sd card are the random Read/Write (512K) speeds? Or else I need to check its sequential speed?
According to a lot of speed tests, SanDisk Extreme Pro is one of the fastest sd cards out there but I also read that SanDisk cards have a quite high failure rate after few months of use (true or not?). Being expensive I've no idea if it would be worth or not.
There are also Samsung Pro+, Transcend 633x, Lexar 1033x etc.. They are quite expensive in Europe and I've totally no idea if my future Honor 6 will be able to benefit to all their fast speed.
I've read this review http://www.anandtech.com/show/8425/huawei-honor-6-review/9 and I'm a bit concerned what the reviewer wrote about the Honor 6, I quote the exact text:
"The Honor 6 offers also a microSD card slot in case you want to expand your storage. The OS offers full exFat compatibility and I had no issues with my Samsung Pro 64GB card. I was however disappointed to see that the HiSilicon chip suffers from the same limitation that plagues other SoCs for no good reason: the DWMMC controller in charge of the SD-card is limited to SDR50 speeds, meaning that you won't be able to exceed ~35mB/s transfer speeds on your microSD, no matter how fast it actually is. It still baffles me that OEMs refuse to address this even almost 2 years after the first UHS-1 cards have been made widely available. "
Is this actually true?
Which microSD you recommend me?
