Anyone know what size AND speed MicroSD card the DInc2 supports up to?
I would love a link to somewhere that gives the specs...
And maybe even a link to a good deal on cards?
Thanks!
By claiming to support microSDHC (micro secure digital high capacity, SD 2.0), they are kinda required by specification to support any card that follows the microSDHC standard. I know this doesn't always happen, but that's the way it SHOULD be.
With that said, I have a 32gb class 4 card in my I2. 32gb is the limit to the microSDHC (rather, limit to SD 2.0) standard, so I suspect any microSDHC card will work.
There is no explicit support for microSDXC (micro secure digital extended capacity, SD 3.0 and 4.0, the standard that allows for up to 2tb capacity by its definition, though I think 128gb is the biggest available at the moment, and those are expensive and hard to find). Apparently the specifications allow for SDHC (and microSDHC) hosts to support SDXC cards at SDHC speeds as long as the host supports a filesystem that can format a volume larger than 32gb (FAT32 has some addressing and table allocation limits, which is why Microsoft stopped using it for primary volumes). Considering Android uses FAT32 and not exFAT (Microsoft updated version of FAT that is more efficient with larger volumes, doesn't have the low addressing limits, and optimized for flash media), I would not count on it properly supporting SDXC quite yet.
I found a Spec List that at least confirms your 32GB figure, but I am still in the dark about what class the DInc2 supports up to.
Anyone?
Anyone?
It SHOULD (key word: should) support up to class 10. However, this may be dependent on model of card. I know the Eris would work with some class 6 cards in the higher capacities, and not others, and would only work with lower capacity class 10 cards.
Best I can suggest is to buy and try. Make sure you buy from somewhere with a good return policy so that you can return a card that doesn't work with your I2. I will say the Kingston Class 4 32gb card has no problem handling the 720p recording.
Is there a way to check what kind of data transfer rates are occurring? Or would the card be unusable/unrecognized if the class was unsupported effectively letting me know?
If the controller/device supports a higher class card, it will work with it at the highest speed possible, either limited by the card or the controller.
If the device doesn't like the card, you'll generally know pretty quickly. I've only seen one instance of a device not handling a card well and displaying that fact through data corruption and it wasn't with an Android device (it was a cheap digital camera). On the Eris, the card just wouldn't be read/would indicate it's bad.

I am curious to know if there is any real benefit to using the SDHC cards which represent larger capacities and faster data transfer speeds.
As i am likely to simply use a 2Gb card, i have the choice of SD or SDHC. But if i know what the actual speed capacity that they handset can handle then that would be very useful.
Presently my 1gb MiniSD card and store TomTom6 on it along with the maps and POI's but i have found that if i load too many POI options then TT6 hangs. So i think this has something to do with the transfer rates. (i could be wrong, but thats my suspicion)
All comments appreciated.
As its unlikely that anyone would have both a regular SD and SDHC cards, could you please just list the read and write transfer rates with the card you have. (please indicate which brand and model of the card)
Thanks

Hello GLO,
the benefit of SDHC is capacity and a standardized write-speed-rating for the cards. The speed is not necessarily higher, as there were a lot of fast SD-cards in all flavours before.
Coming from SD and CF for my DSLR, there has been a phenomenon: While the better SD-cards were really fast, most manufacturers have not built their newer SDHC-cards as fast as their best SD-cards, but just maintained the minimum level for the various speed-ratings defined by the SD-association.
The data for my 2GB Sandisk Standard (no Ultra or Extreme) card according to SK-Tools:
FAT16, 32KB-Cluster:
average write speed: 410,34KB/s
average read speed: 613,48KB/s
From what I have seen on my trusty Dell, the devices do not show much of a difference between standard and fast cards, thus I have just gone for a standard card in my Trinity.
TG.
Hi TG,
Thanks for that. Some very good points you raised!
What card are you using?
So, it looks like there's already a SDXC card. It's 32GB and read/write speed can hit 50MB/s. Not too shabby. Anyway, I was just wondering if anybody knows about any work being done on a driver for this; either by HTC or a third party.

I'm sure there is work being done, but not for any devices currently in existence. SDXC is not compatible with SD/SDHC devices.
Current expectations are for SDXC devices to begin hitting the market around the first of the year, according to CNET.
Which, of course, is a vast conspiracy aimed directly at me, since I was planning to get a Touch Pro 2 just about that time of year, and within 6 months HTC will come out with an SDXC-capable device.
doies this mean the 32 gb sdhc has been cancelled
i heard the 32 gb sd would be a hc not a xc

FYI, 32GB SDHC cards are already in existance, however, I am guessing that you mean 32GB microSDHC cards. In that case...
If you recall, 4GB preSDHC cards never got made by major manufacturers when the SDHC spec came out (even though 4GB was the theoretical preSDHC max). However, small manufacturers did make the 4GB cards and they were easily obtainable on eBay. I infact have a 4GB miniSD from back them.
I would guess that even if the major manufacturers do the same, that is skip over 32GBmicroSDHC cards, the gap will be filled by smaller manufactuers looking to make a buck.
no ui was just wondering
id heard report on a 32 and 128 gb micro sdhc cards
i was wondering if the sdxc was taking over this

32GB has always been proclaimed as the theoretical limit to SDHC, as I understand it - in the sense that it might be possible to create that much storage on one, but no had done it yet, so it's not proven. However, more than 32GB is not possible with the SDHC standard, so if you heard reports of 128, it was likely referring to SDXC.
I image that once SDXC hits the market, SDHC probably won't have much more than 4 or 5 years of practical life left in it as device makers migrate exclusively to the more advanced technology - rather like you don't see many floppy drives anymore.
Hi there,
Can I know will there a speed different between these two micro sd card:
1) 16GB class 2 Micro SDHC
2) 4GB class 2 Micro SDHC
Because I try these two card in my pc, it shows different writing speed. The second micro sdhc only took less than 10 seconds to transfer 5 songs but 16GB micro sdhc took more than 20 seconds to transfer 5 songs.
Why is that happen?
SDHC (Secure Digital High-Capacity) cards are flash memory cards with a minimum capacity of 4GB (gigabytes). SDHC cards provide removable memory for compatible digital devices including cameras, camcorders, PDAs, MP3 players and more. Secure Digital refers to a specific format within the flash card market. SDHC cards are designed for devices that are compatible with the SDHC 2.00 specification. Products designed exclusively to support previous SD specifications 1.0 and 1.1 will not be able to utilize SDHC cards.
The growing demand for high-capacity flash memory springs partially from the increasing use of high-definition video and high-resolution digital photography. SDHC cards meet the challenge of these demanding products not only by providing ample storage but also by introducing a new feature: classifications of data transfer speed (DTS). Consumers can get the best performance value out of their digital products by using flash memory cards that support the device's highest standards for data transfer speed. The SDHC specification 2.00 calls for cards to be classified according to the minimal sustained DTS as follows:
* Class 2: minimum sustained DTS of 2MB/sec
* Class 4: minimum sustained DTS of 4MB/sec
* Class 6: minimum sustained DTS of 6MB/sec
SDHC cards are classified to guarantee a specific sustained DTS. This potentially saves consumers money, as flash cards are priced not only according to capacity, but also to speed. For example, if a product's maximum DTS is 2MB/sec, dishing out extra cash for Class 4 or Class 6 SDHC cards would be a waste of money. Conversely, devices that can utilize the 4MB/sec or 6MB/sec DTR will perform significantly better with Class 4 or Class 6 SDHC cards, respectively.
Secure Digital was forced to create a new specification for SDHC cards when the previous specification topped out at a capacity of 2GB. This occurred previously when SD cards hit the 512MB wall. The new 2.00 specification should last a bit longer, as it allows SDHC cards to reach a maximum capacity of 32GB. Secure Digital is so-named because of its ability to protect copyright content through digital rights management or DRM. Because of this, it is a favored flash memory format in the audiovisual industry.
SDHC cards are about the size of a postage stamp. Insiders expect them to be available through several different manufacturers by summer 2006, and prices will vary. Before purchasing, be sure your device is compatible. There are several card formats available on the market, and devices are proprietary. If a device manual does not list SDHC cards, or state it is "SD specification 2.00 compatible," the device cannot utilize these cards.
But my both Micro SDHC cards are class 2. So should be having the same writing and reading speed right?
I get the feeling its due to size, i have a 4 and a 16 as well and get the same thing
but the 4GB card writing speed is average 1.2MB/s
And the stupid 16GB card writing speed is only average 150KB/s
There is a very big difference....
How are you copying it across? USB into Desire or adapter? (SDHC-SD Card or USB Reader)

I'm using adapter for both cards......
I want to test the speed of the cards, so i transfer some song files into the card.
I did the same for both cards, but the speed is different.
The class is just the minimum write speed, it doesn't mean that all class X cards are equal across different cards/brands. A class 2 card from brand A could be faster than a class 8 card from brand B.
I'm going to buy a 16GB microsd card from sandisk. I've been finding on Amazon and found these two products:
Sandisk 16GB Mobile Ultra MicroSD Card : £36.00
SanDisk 16GB microSDHC Memory Card : £15.99
I've also noticed they're all class 2 (can't find a class 4 or class 6 sandisk). So what is the difference between them? I'm using the card for Windows Phone 7, so which one should I buy?
Ha, i'm looking to buy a 16Gb card for my htc desire and I was looking at exactly the same cards.
As far as I found so far the ultra version seems to be class 4.
If you have any new info it will me much appreciated.
well in some pages you can find comparative boxes about those micro sd, i remember that microsd 16 gb sandisk (class4) is more faster than 16 gb kingtons class4 , so i supousse that this ultra micro sd is like class 6 real XD, i will find some information about it, oh plz don't forget that some devices don't support those kind of micro sd (an example htc hd2 has little bugs with microsd class 4, i have one...)
Sorry if i don't write well but i'm peruavian =)
Hey guys,
Can any of you confirm if Android is booting from Sandisk 16GB Mobile Ultra MicroSD Card ?
I want to buy one but i saw in forums that some cards doesn't work for this..
the ultra one has the better speed and more stable than the normal one. And, it has the same compatitablity.
So, if you are not concern about the price, the ultra one is the better choice.
Also, that should have the extreme III type, that is the best~
Go for the Ultra microSD, it's faster!! been using a 8Gig on my phone and damn its fast!!
16GB Sandisk Micro SDHC
I'm currently using 16GB Sandisk Micro SDHC (class 4) for my LG P500. It is fast & I have not encountered any issues so far.
I've been using Sandisk memory cards for other gadgets & I think it is one of the most reliable brands that is available in my location.
With sandisk/kingston, class 2 should be fine too. CLASS 4 might help recording high def video
Stick with the name brands and forget the Chinese non name brand off off of Flea-bay, they are crap and do not work imho!!
The more expensive cards are usually just higher speed.
I use fast cards in my DSLR to help when shooting bursts. Slower cards fill up, and drop the fps.
I'm currently using 16GB Sandisk Micro SDHC
Go for the Ultra microSD, it's faster!!
You should choose your memory card depending on what you're going to use it for. Either way, you should go with Sandisk cards, as they are the highest quality and produce their own chips. Kingstons should be avoided even though for some reason they are known as a quality brand... kingston just buys chips from other manufacturers and puts their name on them.... you will find many different kinds of chips inside kingston, so you will find more variation and defects from batch to batch.
As far as class, that is only referring to the sequential write speed. If you are getting the card for a digital camera, then a high class card is good, because you will be writing a lot of files sequentially.
But if you plan on using the card for WP7 or to run android of off, generally a class 2 or 4 card is better, because they have better random access speeds. The tweaks card makers do to make cards have higher sequential write speeds many times will lower the random access speed, so you will have more issues running WP7 or Android off of a class 6 or 10 card.
for 8gb ultra i got with usb2.0 card reader : 13mb/s write , 20.5mb/s read
I know the thread is old, but still.

I know thread is too old to write anything. But still (since google pointed me here)...
I've used both types of cards and have found that Sandisc ultra (Red & Black) is far better in speeds and reliability than the Sandisc simple/normal black colour chips. Also know that there are further/more better than ultra, called by Sandisc as extreme and Extreme Pro.
Also warranty for all is same: Lifetime. And Sandisc provided me a new chip within 25 days after my old 32 normal chip went faulty.
Re
I would always buy a class 10 card, because when you copy your photos it doesn't take so much time...
I discovered - the hard way - that "normal" class 2 or 4 MicroSD cards won't stay alive very long on Samsung Note 4 or similar phones... One day they stop working and all pictures and info is lost forever. The only MicroSD that can get the job done is a Class 10 UHC Sandisk card. I have used Kingston and all died only after a few months, specially if you install apps on them. They can´t handle the workload and you will end up losing everything you have on them. I have one of the red and gray Sandisk cards and it's awesome. It's fast and it's still working after 2 and a half years of use in a Sony Xperia Z2. Gotta love this little tough card.
Although not a question dedicated solely to the OGP, i figured others with this phone might also want to know....
I'm looking to get a 64gb card for the phone to store music and whatever else can be put there (I realize apps can't go on the SD). I've seen class 10 cards and other slower classes for sale online. Does the speed of the card make that much of a difference for the uses that we need? I'm assuming that any class of card would be sufficient for music, but then again maybe I'm wrong. Someone please educate me!!!
I realize that with a digital camera, you want a faster card to quickly store the image you just took, so you can get on to snapping the next picture, but with our phones do we need the faster storage that class 10 provides? How much does it matter?
Also, I understand there are apps that swap the built in memory location for the Micro SD location (sorry, I'm an Android newbie and I'm just learning), so that I could have 64gb of "built-in" storage for apps (minus the OS), and 23gb for "external storage", then would the speed class of the card then come into play much? How fast is the built in memory compared to a class 10 SD card?
the thing i can say is class 10 helps a lot for "scanning media" process which comes :
every time you boot the phone
every time you move some media or add some new
before i had a cheap one and it was long....
Built in memory will typically be faster than even a Class 10 card. The other day I picked up a 64GB MicroSD card from Best Buy (half price at $50) and put a ton of ripped movies into it so I can show of that 5.5" screen. It scanned the 50GB of files in a few seconds and I haven't noticed any stuttering, even as I scroll through the videos.
All of the 64GB MicroSD cards I have seen have been Class 10 anyway, so don't worry if you pick up a 64GB. This is the one I purchased (same price as Best Buy):
http://www.amazon.com/SanDisk-Micro...e=UTF8&qid=1371505587&sr=1-1&keywords=microsd
And I do see a few non-branded cards on Amazon, but I would stick with a name brand. There is a reason they are selling for $16.
And, to make it more confusing, I've seen Micro SD and Micro SDHC cards. Can the OGP use both types, and is one better than the other?

MicroSD is anything under 4gb, 4-32= SDHC above 32gb = SDXC. The OGP can accept any of them (up to 64gb).
