Just a quick question about memory cards. I have read on this forum that it is possible to run a 16gb class 6 high capacity secure digital card in a HTC Universal running a Windowmobile 6 Rom 2.09.01_BL__B_V1; can the same also be said for a 16gb class 4 high capacity secure digital card? I have found one on the net that I am thinking of buying but thought to ask before doing so. The item is http://www.amazon.co.uk/Integral-16Gb-SDHC-Class-Card/dp/B000ZOVB0Y/ref=pd_sbs_ce_title_9
I have a contract with O2 and have been informed I am due an upgrade, I have had a look at the O2 Orbit 2, nice looking device; what are the other names for this device as I am unsure?
Thanks for viewing and replies welcome.
Yes ,it support my Toshiba 8gb class4 very well!
the "class" on SDHC cards only marks their speed.
it's the "guaranteed minimum consecutive write speed" in MByte/s
So a class 6 card must be able to handle 6MB/s write speed. It may be a lot faster, but if it's slower you can return it as defective.
The only difference between a class 2 and a class 6 card is that one uses better memory chips than the other, so it can receive/transmit data faster. The interface / layout / pinout / logic / data structure is all the same.
It's like 12x and 52x CD-R. You can use both in any drive that supports either, just the one gets the job done a little faster than the other.
Of course that the card can handle 30MB/s doesn't neccessarily mean your universal can, but it should work (at the universals maximum speed) nontheless.
I'm using a sandisc 16GB SHDC class 6 card at the moment with a Crossbow rom, runs very well.
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.
I want to upgrade the stock 4 GB microsd in my unrooted htc desire to a 16 GB microsd card. My question is can I copy what is on the 4 GB microsd and transfer them to the new 16 GB microsd and just insert it in? would all programs work?
many thanks for your help.
Yet, the apps are on the phones memory and the info is on the SD card so you can just copy across.

Are ebay unbranded 16GB microsd cards reliable? Do they work?

I agree - I had lots of problems with an unbranded 16GB card. Eventually ebay closed the seller down as there were so many complaints. I did get my money back via paypal. I finally bought a branded 32GB card - costly (EUR100!), but I love having so much space for my music / video.
Is there really a need for anything above class 4?
My HTC Desire came with a sandisc 4GB class 2. I want to get a larger card, but never had any reading issues with the class 2, and music and video played off it with ease.
I've seen the following item here, which is for a class 6.
http://www.amazon.co.uk/Transcend-m...r-TS16GUSDHC6/dp/B001PLIG5Y/ref=cm_cr_pr_pb_t
Anyone got one of these?
I've just bought the 'ultra' version of Sandisk's 16GB microsd card and I am very impressed with it so far.
Personally, I always feel that it is best to stick with the tried and trusted brands, and sandisk products have always been excellent for me
I just bought a 16GB SanDisk class 2 from amazon and it writes on average at 5MB ish
-------------------------------------
Sent from my HTC Desire
I thought the class number i.e. 2 meant the read and write speed 2Mbps. Therefore class 6 would be 6Mbps. If you have a class 2 and get 5Mbps then that is pretty impressive.
The Class of the SD card is simply the *minimum* sustained write speed on a card which is completely unfragmented. So, a completely blank Class 2 card should always be able to write large files out at least 2mb/s, but can easily be faster.
My 16gb Sandisk Class 2 reads at 20mb/s and writes at 7.5mb/s - well above the Class 6 minimums.
Regards,
Dave
my 32gb is a class 2 and i have zero issues with streaming video or music from the card, i expect when i root that apps will not be an issue either. plenty of read write speed.
the higher classes are for devices that require a higher bitrate for recording such as mini hd recorders and such.
Im running a SanDisk 16GB Class 6 and its like Lightning!
Will i need higher than class 2 microsd card to support HD recording on the DHD something like ultra high speed class 6 microsd card for better access speed?
Though im not sure if class 6 is supported on the DHD. if anyone can shed a light on this is greatly appriciated.
As they provide a Class2 card with the phone and advertise 720p video recording, the Class2 standard is apparently enough. This is just a guess, but I strongly think that DHD supports Class6.
Ok, just not too sure if class 6 is based on ver 2.0

It's enough cause we are talking here of a phone that has plenty internal memory to buffer data when you are recording stuff in 720p!!! Class 6 or 10 are needed on digital cameras or digital video cameras cause they usually don't have such huge internal memory to buffer data while recording...
Basically we are talking DHD as almost a computer in these particularly case
something else to consider is transferring anything to your phone or back again to a pc or mac. A class 2 card will be much slower than a class 6 or even a class 10.
I just thought I would check what Class my N97s Micro SD card was and it is a class 6 8GB, so that should keep me going for a bit.
Its pretty rubbish that when people are pay £500 for a phone, that they ship it with pretty old technology micro SD card.
Class 4 16gb kingston microsdhc are pretty cheap
guys what do you all think about this one
Transcend 16 GB microSDHC Class 6 Flash Memory Card
Look it up in amazon
it looks pretty good

i've placed an order for one of this for £23.00 through amazon. Doube the capacity and in theory speed than the sd cards the came with my DHD
please post what micro sd card you are using and how you are finding it on the DHD, just so we can see which works the best.
the reason i ask is because I am thinking about getting a bigger micro sd, but not sure what to go for!
thanks
I got a Toshiba 16GB Micro SDHC card from these guys for my DHD for £16.99 inc P&P, and it works great : http://www.7dayshop.com/catalog/pro...d=106505&PHPSESSID=4foeg41alltvi1s6sifidtoip0
Its rated as a Class 4 card but I have actually obtained steady transfer rates of 6.5 MB/s and even at times up to 10 MB/s with it whilst copying across large files from my PC to the phone via USB.
I really should look a bit closer before posting!

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.

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.
