i just bought a 4gb topram mini sd card. i saw that most pocket pc read thisbut then again i wanna be sure ....
does the o2 xda atom (the one with the 416 mhz processor) read a 4gb card?
pls reply soon...i need to know
I'm trying to figure out the same thing myself.
The official O2 Website says that the maximum mini sd card they've tested is 2GB.
I'm not sure if a 4GB one will work.... I dunno??

Hi, I was using a 4gb mini SD card on my Atom until recently when I brought Gigabyte GSmart i300. So, there shouldn't be any problems.

Thanks for sharing the info.... would you reckon a Sandisk 4gb mini SD will work on the original atom ?
There are 4gig miniSDs? I only heard of 4gig miniSDHC. If SDHC worked on Atom, I'll be wildly happy. >_>
wats the difference between SDHC and mini SD?
omg thanks Invisible Sense for the info, i just hope this one actually works on mine cos i cant be sure, it could depend on the memory card make or firmware version.
and yer, its been mentioned in quite a lot of sites around...wot exactly is the difference between sd and sdhc? someone reply pls
sdhc is new tech pretty much, lets manufactures to make higher capacity... and the HC is just that means high capacity, they come in ratings of class 2-6 atm as far as speeds, unlike the sd ones which would have like x50 x120 x150 etc... and it will say most time sdhc or sd high capacity
i believe it has to be hardware support for sdhc, so no firmware cant just be made for it to work without hardware change
i am using a utek 4g mini sd on my atom life, transferred more than 3g of mp3s and movies to the 4g mini sd, so far so good, no problem at all with the utek 4g mini sd, hope this helps.
does it affect the memory?
the hc only varies speed right? not like 4 gb equivalent to 8? cos its high CAPACITY not high PERFORMANCE :S which should be associated with speed. i dont get it ..
capacity means contain...contain is storage....
oh and atom life is one of the best out right now ..so it would obviously take a 4gb card..i meant the normal regular O2 xda atom
http://en.wikipedia.org/wiki/Secure_Digital_card#SDHC
that might help you understand the difference
Disregarding the wiki, the difference is not just in the storage. It's in the driver. The limits are hardcoded and you have to redo the entire driver just to get it to read - and because these drivers are proprietary, you only get SDHC if your vendor chooses to integrate 'em. You're otherwise sadly out of luck.
(I still think SDHC doesn't require new hardware - vendors are spewing out a load of crock as an excuse to not support the older stuff. Especially when you consider that there exist camera firmware updates that convert slots for SDHC use out there - for cameras that were made WAY before even the 2.0 format was on the table. Even Sony's memory stick slots only required a driver update - SD, the reverse engineered clone of the Memory Stick standard, should not be any different.)
I have a Adata MyFlash 4MB x150 card and this runs fine, the TT5 runs of this and is very quick, no problems with WMA or camera pics.
By the way this is an XDA Exec, latest firmware

Hi Rizwan,
I got my 4gb Mini SD from the website below.
It's now only £29.99 and mine came in just 2 days and that was back in December.
Hope this helps!

How is the speed on the card though? Is it slower than say a 2gb do u know?
I did have a 2gb miniSD before and can't tell any difference.
I do transfer a lot of data such as movies and music so have been used to the speed of the two cards. I will say though, having a 4gb card was far more important to me then speed, therefore I didn't care about the speed much.
My new phone Gigabyte i300 comes with USB 2.0 and I must say the speed of data transfer is amazingly quick.

Yeah you're right...... as long as it ain't too slow, speed isn't as much an issue as capacity.
I just bought an atom a couple of weeks back....I think I'll go for the 4gb card when my atom arrives!
Thanks a million for sharing the info!
many thanks
thanks for all the info ... uv really helped me out... many members here seem enthusiastic to help out...im glad i found this forum. ill let u guys know when i receive the card. i bought it from ebay btw...just in case anyone wants to know where i purchased it..
thanks
well when you think of the speeds, IMO it is a big deal esp when running apps on the miniSD anything that will precache etc...
but you might not notice speed difference because depending on your device, you might have to plug the card into a usb 2.0 card reader to get the benefits of higher speeds... and even then some card readers cant match it...
all i know is through device its slow if your using hte active sync i belive, if you do like one some devices as a card reader i believe it will work with usb 2.0 then, but active sync might be slow 1.1 usb?
also it seems that on the US side, the good high mem 2gb 4gb miniSD are missing, ebay has some but some brands are crap and going with oem can be fishy, if you guys read the issues with the other 4gb cards dieing and what not..
How i can run my 4gb sdhc memory card on my nokia n 73 music edition?
Hi,
I have already tried with my N73 ME but the phone don't read the 4GB SDHC.
Lele.
wtf, this is neither development nor hacking, nor even wm...
strange, yet it raises a good point, is there a good forum for general mobile phones?
Rory
anybody has experience with one of these?
does it slow down the htc hero??
i have a lot of music on my hero and i notice everytime the hero needs to access the sd card it lags a bit, i notice it when i open albums and when i open my music library it lags for a little like if it scans the whole sd card first,
so im thinking the more space the sd card has the more it will lag for these things, anybody got one and can share their experience?
More space != more lag
If you have a faster card it MIGHT have a better chance at faster access. So a class 2 card might seem slow compared with a class 6 card. I haven't seen a definitive test performed on the Hero and the different card classes throughput though.
A card with equal throughput (class speed) will require approximately equal lag time whether the card is a 2gb, 32gb, or anything in between.
Since this is on the topic of sd card, where's the cheapest place to get these?
I've found 8gb class 6 cards on Amazon, but as for 16gb and 32 gb class 6, it seems a little ridiculous in price difference.

Excerpt:
This is what HTC told me [when I asked what class card to purchase]:
"Good Morning Frank,
Thank you for taking the time to contact HTC America Technical Support via E-Mail with your inquiry about what class of SD card to use in your Sprint HTC Hero. My name is A.J. and I will be happy to assist you today.
If you are looking to purchase an SD card that the device will read at its full native speed you will need to purchase a class 2. The device will read a class 4 but not at its native speeds.
Frank, if you have any future questions about your device please feel free to visit HTC - Touch Phone, PDA Phone, Smartphone, Mobile Computer and send us another e-mail. You may also enjoy HTC Smartphone Wiki - HTC, which has a plethora of information on HTC devices, including the Sprint HTC Hero! I would also like to invite you to participate in a customer satisfaction survey located at HTC Online Survey I hope you have a great day!
HTC America Technical Support

So it looks like the HTC Hero will read class 2, 4 and 6, but not at the native speeds for 4 and 6. So it seems like a moot point of "what class to buy" if the data bus isn't going to take advantage of a faster card.

I am becoming more and more disappointed with HTC and sprint. Too many factors being left on the table for my taste.
well is that a hardware or software aspect of the hero?

It's a hardware aspect, like our cpu and ram.
has this been verified by any benchmarks or can it be? i'm thinking about jumping off on a bigger card, just haven't seen anything definitive about it
i've heard severa people report speed increases by using class 4 or 6 cards. Might not be native speeds but faster than class 2... just a thought.
Currently I'm using a kingston class 4 and the speed difference in loading music or pics off the card is not noticable. I got it for APPS2SD and Linux Swap whenever someone decides to utilize it in a rom.
Can someone post a link to a 32GB card? I can only find dual 16s from Tropam.
I thought San Disk wasn't releasing the 32 GB stuff until next year because they are hit/miss on full storage capacity still.
EDIT:
this year I guess...lol.

tbh i can't find one either... maybe they aren't even released yet? i will keep looking
on my question though...
is there, or can there be, an app that reads/writes test files from the microsd card and tells you how long it took to read/write.... you know, a benchmark... seems the only way to be able to tell if there is a real diff between the classes
from wikipedia
"In February 2009 Sandisk also announced a 32 GB version for the second half of 2009,http://en.wikipedia.org/wiki/MicroSD#cite_note-4 but as per end December 2009 it is not listed yet."
The Hero has no problem significantly exceeding the capabilities of a Class 2 card.
Using the C2 card the phone came with, Windows 7 reports reads maxing out at about 3 MB/s. Using a C6 card that I bought, Win7 reads at 10 MB/s and writes at 6.5 MB/s.
if anyone experienced in java wants to take a crack at it, maybe they could write a native app to benchmark r/w speeds of our sd cards. I think that would be rather handy to have even if it was limited in usefulness.

No, because it's using the phone's hardware. I'm not taking the card out of the phone - I'm plugging the phone into the computer.
I ran some benchmark program called ATTO or something last night, and it was consistently giving me 5 MB/s with the Class 6 card and 2.5-3 MB/s with the Class 2.

That makes sense.. but HTC still refuses to say that it will take advantage of it.. but an "in Phone" app to seal the deal would be great.

right, it's still in the phone, but the phone isn't reading or writing the card, your computer's OS is, while the card is mounted... acting like a usb flash drive... someone correct me if i am wrong...
was the ATTO prog on your pc/mac or on your phone?
thanks

The contention is that the card-reading hardware in the phone is incapable of read/write speeds greater than "class 2" speeds. The OS has no card writing speed limitations built-in.

Id say thats news given that 64GB Micro SDs didnt exist when our HD2 was born.
To be honest, i dunno what id use that much space for, i dont think id ever fill a 32GB SD let alone that monster!
There was a time when id have dual booted android, but i cant be bothered with all that now WP is pretty much perfect on the HD2,
Hi.... Just wondering... Did you experience any change in battery drain and smooth running of the rom after installing 64gig sd card ,
And which rom unr using currently...
This is epic for someone like me! I'm one of those people that fills up 16 gigs in no time flat! 32 sounds nice, but 64 gigs!!!! I'm in heaven, I need to get one. How much did the 64gb card cost you?
Any updates on whether this works yet? I would like to upgrade from 32Gb soon.

Seems he has 64gb working, what's your battery life like with that card? I think SD card the main reason we all experience such different levels of life...

wow. amazing. does it mean that hd2 supports part of SDXC? can you use all of the storage volume;about 59GB?
I have mine split, but yes if you so choose, you can use all of the storage on the sd card, currently i have Everything working on the phone, running really smooth, only thing is that my carrier signal/reception is good, but for some reason the radio on this rom seems weaker than normal, Question for anyone that knows, is there a better one ready yet, I am on Orange.

THing with Radios is that firstly we have 2 different radios to deal with, and secondly different networks and signal strength areas will do better with different radios, so you may find that the latest and greatest radio is actually worse than the first radio available because its been stripped from a phone on say, the O2 network.
Trial and error appears to be the best, or ask folk on your network what they use, ideally in your own country and even better near you,

According to the SETTINGS|about page, I have 59.25GB Total Storage.
Battery life is not stellar, though I haven't really done any work to optimize that.
SDXC
Basically... All SDXC cards will work...
The thing is, this is how the cards are supposed to be shipped:
SD => FAT
SDHC => FAT32
SDXC => exFAT
Any SDXC card can be formatted as FAT32 to work with SDHC compatible devices. The OS "decides" how much of the storage capacity can actually be allocated.
Since microsoft probably took note of SDXC during development, windows phone uses a file format that either supports exFAT (which is a MS file format) or formats the cards in a file system that supports over 64gigs. Windows phone supports SD cards under 32 gig, so it supports FAT32 and FAT anyways (to be reformatted in the device)
Long story short, as soon as a device supports exFAT it is SDXC compatible. if a device supports FAT32, any SD card formatted in FAT32 works.
Will the 64GB SDXC card work with the original Windows Mobile 6.5 ?
Does exFAT work on WM6.5?
Wohooooo 64 Gb for what?
Yep got a dual booting 64gb SanDisk class 6 over here.
30.8 in windows
30.5 in android
(couldn't find a way to put more in android than windows b/c ad sd and wp7 nand.)
Battery drain seems the same. Check everytime I boot constantly to see if the current is -400 or -4.
Such a pain in the anus.

Seeing as how Windows Phones uses the partition type exFAT, it'd be no problem picking up the 64Gb card since that is what it is formatted as.

In regards to the SanDisk Ultra 64GB SDXC...over the last couple of days I installed the NexusHD2 v2.3 and set the card up with 8GB EXT4 and 52GB FAT32. It ran slightly slower than NAND but I adjusted the CPU speed to compensate and overall a darn good experience. My next adventure was to dual boot both NexusHD2 and Pdaimatejam's WP7.8 and I split the card pretty much right down the middle taken into account the 200MB FAT32 WP7.8 creates upon it being deleted and for one brief moment you have only 2 partitions before continuing to create the EXT4 partition. WP7.8 will works up to a point and then begins the reboot loop. I understand there's a way to image a smaller memory card onto the 64 gig card and that's what I will be doing next. In the meanwhile I did successfully load Pdaimatejam's ROM into NAND but the key here is that card must be formatted as exFAT; otherwise it too will reboot endlessly. My only use for Android are CoPilot Navigation and Google Navigation and Skype; otherwise I prefer Windows Phone for one reason and one only; it runs as smooth as silk but WP7.8 lacks what WP8.x now haves...good GPS Navs, what my Titans and HD2 have is customization and that is a sticking point for me in regards to upgrading to the Lumia 92x series.
