1GB Secure Digital Card - What to put on it?

I'm just curious what all you 1GB SD card owners put on it when used with the XDA 1/2.
I ordered mine a few days ago for £94 inc delivery from NYC on eBay. It arrives tomorrow.
If I can't think of anything amazing I'm probably going to fill it up with MP3s, but these seems a bit of a waste of a 'Pocket PC'.
I've got a GPS unit and TomTom 3, so I've allocated 100mb for the UK map...
I've got a further 150ish mb of apps and games from my old SD card that I'll probably keep....
So that leaves 750mb...
But wait, I've still got the 250mb SD card it replaced, so I've still got 1GB to fill...
Suggestions please!

I've got:
1. Some games
2. Home videos made by XDA II Camera
3. Movies
4. TV Shows

I have on my card:
- TomTom D-A-CH (256MByte)
- Wikipedia, complete (!)
- several eBooks, including some law books
- from time to time a few DVD rips (from DVDs I bought!), to watch during a train ride for example
- a few nice pictures
- MP3, of course
But I find it actually quite useful to leave a few hundred meg free, so I can use the card to transport data from here to there if necessary

All that space makes you wish XDA2 had USB 2 thats for sure!!!

How is the experience with read/write speed on these 1GB SD cards??
See http://forum.xda-developers.com/viewtopic.php?p=52965#52965
I have some problems with my 256MB SD from Kingston in combination with TomTom3 (on SD: maps and 1 extra POI file activated makes TomTom3 freeze when the data-transfer rate gets behind to the needs of TomTom)

All that space makes you wish XDA2 had USB 2 thats for sure!!!

i seriously doubt that the xda2 could ever reach the usb2 speeds of 480Mbit

How does the P3600i compare to P3600? More reliable?

I was on the fence about buying the 3600 when I read of many people having problems with the screens going out, system slowing down when touching the screen, and the metal peeling, slow performance, ect. I didn't realize that there was a new one, 3600i. Has anyone had any similar issues with it? How is it compared to the 3600 as far as reliability? I believe this would be my perfect device if it just supported SDHC.

The P3600i does support SDHC, at least to 4Gb. Can't test higher capacity mini-SDHC cards yet, not available here.
Oh, BTW, the Quick Fix GPS cab file does work, despite the "placebo" sceptics. Tested exhaustively now for 4 weeks. It downloads ephemeris data from http://www.htcusainc.com/clm as packedEphemeris.ee for NMEA mode. This is exactly, precisely, the same data file for SirfIII GPS in NMEA mode.
TTFF is now 30-60 seconds. Before, 5-10 mins, about which I had justifiable criticism.
Regional setting HKLM\SOFTWARE\HTC\QuickGPS\region
needs to be correct. I'm using AU for obvious reasons.
The P3600i is now in my view as close to perfection as I may wish.

ROM and RAM higher than 3600,so I think the speed will be higher and stable when run large program.for example,Map guide,etc.

Ian,
I am surprised to ear that P3600 support SDHC 4Go because i bought mine 2 weeks ago and before buying a mini SD i put the question to HTC and got this answer:
Dear Sir,
Unfortunately the HTC P3600 does not support the mini-SDHC format cards, only standard mini-SD. The maximum size you are able to use in the device is 2GB.
Thank you for your enquiry, Should you have any other problem, please do not hesitate to call us. Your Local number can be found at http://www.europe.htc.com/support/csbyphone.html
So i was just prepared to buy a 2GB mini SD, can you confirm that a 4GB SDHC works on a long term basis?
About quickGPS do we have to launch it only every 7 days and nothing else than starting normaly our GPS software (tomtom)? I tried qGPS but i do not see any difference in the fixing time after starting tomtom.

My p3600 Italian version supports SDHC. I'm using a 4GB right now.

8Gb sdhc
Hi!
I using 8Gb micro sdhc card with minisd adapter, and it's work in my p3600.

There is the P3600 according to HTC and the P3600 according to XDA-Developers.
The P3600 according to HTC: WM5, no SDHC, and 4GB-Mini-SD (without HC) is not really a standard so nobody will assure compatibility.
The P3600 according to XDA: WM6, SDHC-compatible due to a new driver.
Beware: There are a lot of different flavours of WM6, as they are built by different persons, not directly by HTC. Their reliability is very different, read the threads to judge whether a built is more shiny, more stable or both.
QuickGPS does not work on the P3600, the standard rule is valid: Don't move until you get a fix. You might save up to 10 minutes.
Have fun!

128 gb microsd...when is enough ENOUGH!

Come on folks...128gb microsd?!?!
At first I was excited about the Sandisk announcement (http://dailymobile.se/2008/10/20/sandisk-to-develop-128gb-micosd/); but then I asked one question--When will this end?
I'm torn between constantly buying "the next biggest memory card" versus start storing everything I need online.
Sure they both have their PROs and CONs -- but since 99% of my travels are in a 3G area...
...why NOT use one of the many FREE picture/file stores online?
...and why NOT watch movies and vids online instead of a downloaded copy to my memory card?
...and why not start storing my contacts, calendar, tasks and everyday To Do lists online too?
...and why not even run my desktop applications online where I can access them anywhere I have connectivity?
We Tech OGs know this "cloud computing (Web 3.0)" is nothing new--remember DUMB TERMINALS and THIN CLIENTS? Amongst other advantages, it was SUPPOSE to put a halt to ever-growing disk space needs and excessive licensing costs back in the 1980s and 90s. It didn't really fly...and so now Here we go again.
With only a handful of today's mobile devices having more than 640K of RAM, maybe Bill Gates was right after all when he supposedly said "640K of memory should be enough for anybody".

What is better than to have a large cyclinder capacity?
Right - even more cyclinder capacity ...
I am not traveling always in good 3G connection area and I like to carry arround the data I need. The more the better, for me it is realy that simple.
Wikipedia, MP3s, Navigation, Presentations, fotos, documents, etc.
With a smal card I have to select the data. The larger the card the easier it will be - just have everything.

128GB on a MicroSD card is just insane.

Been there...done that

Until about 2 years ago, I loaded gigs of TomTom and Mapopolis maps to my SD card. The problem was those maps NEVER had street names and areas less than 4 years old. So I abandoned that and started using Google Maps, YahooGo and Nav4All. The only downside is that an internet connection is now required. I'm now starting to go online with fotos so I can share. I abandoned loading encyclopedias, dictionaries and wikis to my SD cards a long time ago. To me loading those on a card is the same as carrying around hard/printed copies. It's outdated the second you put it on paper. By accessing those online, in theory, you'll have the latest updates.
My only concern with accessing contacts, calendar, tasks and documents online is SECURITY.

Not long ago I spent $60 on a 4GB micro SDHC
Haven't come close to filling it -- but when I saw a 8GB for only $25 last week, I just had to grab it.
I just might do the same when 16GB get to that price point.

I spent the equivalent of $12 on a 4GB Micro SDHC the other day.

I have the same problem and now it has been sorted!

Meanwhile this rule of thumb isn't true anymore. The pressure inside the cylinder affects the power of an engine too. So more cylinder capacity isn't neccessary that much.

Had a 512MB SD Card - was enougth but a bit too small ... !
Upgraded to a 1GB SD Card - was enougth but again became a bit too small.
Bought me a 2GB SD Card - damn, still not enough space ... !
Got me a 4GB Card - ... will it ever be large enough for my needs?
Sitting on my 8GB Card - ... not enough space !!!
Well, avoided so far the 16Gig Card because I think it is just too expensive! Hopefully prices will drop soon - so, 128GB would be cool, I could get rid of my 160GB USB drive.
However, I doubt that any currently available MOBILE HANDSET would be capable of handling a 128GB Card ... !

..let me hear ya say tera. oh yeah

The more space you have, the more space you´ll need/use
So the "When is enough" will have to be answered by users and not by manufacturers. The day we don´t buy something that will be the day when they maybe say "Now it´s enough"

Keep in mind those Cards will be used as well for other things then Phones. with a USB reader ( that you could carry on your key chain) you could carry complete data of your desktop with those. (pictures. movies,music etc)
I am selling those readers and many company's that have been using CD/DVDs moving to USB readers with cards. >see the picture for sample<

Untill you also fill that bigger cylinder with more air....

I suppose the question is not necessarily whether or not "when will enough be enough" but more so "when will they develope phones with much better camera and video quality? That is when the large SD cards will come in handy. 4 years ago Samsung made a great phone for Verizon Wireless. It did nto sell well because it never had a great sale on it but the thing had amazing video, camera, and even voice to text on it.

like this nokia n98? id rather buy a camera and a phone/pda i mean its not like digital zoom is amazing or anything, but yeah that would use alot of space, so would a phone with better screen resolution then all of the games/videos would be bigger. there probably wont ever be an end because people are lazy so they program lazy and dont optimize code and people want everything to be hd so everything will be bloated just for graphics

Wow, that is a pretty sweet phone anda carl zeis lens is really killer for a phone! So I guess that would be a yes.

so this is still using the SDHC interface or what??
it wouldnt make sencse to make a new subunit of SD if it can only go 128 Gb, because face it........ that isnt large enough to support another couple of years.
the jump from 2 Gb to 32 Gb was pritty big, 16 times the capacity.
32 Gb to 128 Gb is nothing compared to that first jump, its only 4 times bigger.

The real question should have been. Where can I get one and how much?

I plan to get the 128GB SDXC in that thread.

Thanks, but those are SD, not micro SD which is what we need for smartphones.

When should Microsoft update the Hardware Specs and what should be included??

Apple update the spec of their devices every year and I think Microsoft should look to do this also...
In addition to the Gyroscope and new processors metioned at MIX I would like to see the following...
Fall 2011 - Windows Phone 7.5
1. Front Facing Camera - Launched with Live Messenger, Skype etc...
2. 16 GB Minimum Memory - I have no space for new APPS on my 8 GB device!!
3. SD Card option like on the Samsung Focus as standard.
Fall 2012 - Windows Phone 8
1. DLNA - Stream movies, photos to TV
2. Windows Button to also be 8 directional D-PAD as standard.
3. Allow remapping of all buttons when in Game Mode.
3. NFC - contactless mobile payments
4. USB 3
5. Bluetooth 3 or 4
6. XGA Resolution 1024 x 768
7. HDMI
8. Dual Core processors - multiple suppliers
I am sure there will be Android devices that meet these specs by late 2012
Low end devices would stay as WP7 and WP8 would support the high end features... Microsoft has already said this is the strategy.

I think the most important update should be software and increase in software features to improve the versatility of the platform. Windows 7 phones as at now are by no means low in specs.

Agrred the current specs are high enough for the momment. The main problem is software develpoers trying to create sual core supported software which, means its better if ms wait a while and do what andorid have whereby they have increased spped of the os and added new features and battery saving features mainly. Also speed wise JIT would be good.

The specs are fine, but I do see them improving, obviously. I've stated in other threads I see them updating faster because of market production and not because of necessity, unlike Android.
With that being said, I do see FFC coming this Fall. Though, obviously, they won't be mandatory, and will probably be featured on the phones on par with what's available today. Video out will probably be available sometime, though I don't think in Mango, but it would make sense with Netflix on the device. They won't go with multiple suppliers of processors, that takes away from the consistency of the device... And Qualcomm is a fine manufacturer... Why the need for change here?
Resolution has also been said it won't change, hasn't it? Really don't blame them, again, consistency. As far for hardware adjustments... No... Just... No.
And the memory option affects price. There are 16gb devices, why didn't you get one of those? I have 16gb -.- They need smaller devices to attract different users, you can't only have max devices on the market.

1. Front Facing Camera - Launched with Live Messenger, Skype etc... - Useless without the Apps. Not sure if Skype wants to tax their network by just letting any and everyone video call right now, TBQH...
2. 16 GB Minimum Memory - I have no space for new APPS on my 8 GB device!! - Why did you buy an 8GB device?
3. SD Card option like on the Samsung Focus as standard. - They're better off setting the minimum storage to 16GB than add a slot IMO. SD Cards lose their utility with the way WP7 uses them, and it's a PITA to use them after you take them out the phone as well...
Fall 2012 - Windows Phone 8
1. DLNA - Stream movies, photos to TV - Standard on High End Android devices.
2. Windows Button to also be 8 directional D-PAD as standard. Huh?
3. Allow remapping of all buttons when in Game Mode. - That still wouldn't make the phone a decent gaming device. Have to go the Sony rought to have something decent, IMO.
3. NFC - contactless mobile payments - Becoming standard on Android phones. Newer Blackberries will ship with this as well, and I suspect the next iPhone will as well as WebOS devices.
4. USB 3 - Unnecessary, IMO.
5. Bluetooth 3 or 4 - Galaxy S phones shipped with 3.0 in the middle of last year... Kinda late for this but it doesn't matter that much if your other devices don't support it, IMO.
6. XGA Resolution 1024 x 768 - Unnecessary on smartphone screens. Even qHD is IMO unecessary on screens 4.3" and below. Apple can afford to put this because they charge a premium for their devices, but it's pretty meh. qHD is decent, this is overkill...
7. HDMI - This is a pretty standard feature these days...
8. Dual Core processors - multiple suppliers - Agree...
I am sure there will be Android devices that meet these specs by late 2012
^ Apart from the screen resolution and USB3, both of which are pipe dreams... There are already Android phones that meet or exceed these specs now...

^ Link pls... WTB Windows Phone fragmentation?

If Microsoft wants to wait until Fall 2012 to introduce half that stuff you have listed... They mind as well just give up now.
Do us all a favor and ask them to put better batteries in their smartphones. The issue with smartphones is not the hardware. Even 1st gen snapdragons are good enough to make a good, featureful, performant smartphone OS on... The issue is that these phones last half a day with heavy usage, when you could do 2-3 days of heavy usage on Blackberries and Nokia phones...
No one cares how pretty it is or how well it performs if they are tethered to a charger all the time, and that's pretty much the status quo for WP7/Android/WebOS and to a lesser extent iOS these days...
Even with 1800-1930 mAh batteries phones like the Galaxy S II/Atrix 4G etc. manage to have battery life measured in < a day of moderate use... That's pretty incredible (not in a good way, either). It's time for manufacturers and companies like Microsoft/Google to stop feeding the needless spec bumping and focus on something that matters more - making phones that won't be rendered useless for hours due to being tethered to a charger if you happen to doze off at night before you plug the charger into it.

Better Battery Life in general, as N8ter said. I think this is the thing iOS, wp7 & Android platforms really need to focus on more right now.
16GB minimum internal NAND memory, although I hope to see at least one 32GB or more (probably Nokia) in the next year. Memory is not that expensive, and if we are to have our music collections on our phones, Nokia and Apple are the only ones who seem to get that you need space. I'll pay a little more for enough storage.
The new processor spec's are fine, don't need dual core yet but would like to see them start to come out by early next year.
I really expect a front facing camera phone will be out with Mango due to Skype being released. One of the OEM's will have one as a flagship if not more. But do people really use this feature much? Not really, but it still has uses, and those who will use it and should be available with Mango imo.
Other than that, its additional software features that are needed most. Mango is taking care of a decent list of complaints I had as will Nokias Navtek data/Ovi maps, but there are still many things to be added.

Fall 2012??? OMG... If Mango can do good enough... Mango is still WIP, so why don;t they add some feature that might "Magnet" some other users? 1, 3, 5, 7,8 from Windows Phone 8 are good example to be put on Mango.

I agree, but the manufacturers charge too much for strage. Going from an 8 to 16 GB phone can easily add $100 to the price at times. It's ridiculous. They will nickle and dime at any opportunity.
Nokia phones only needed a decent size ROM. They have SD Card Slots. Same for Windows Mobile and to a lesser extent Android. iOS, WP7, and WebOS devices need at least 16 GB internal storage, because of the lack of an SD slot or the way the phone works with SD Cards (WP7).

Nokia's N8 has 64GB internal storage (if I remember correctly). Doesn't NAND memory work better than internal + a removable SD card? I never got great performance out of my SD cards in BB, Android ect. And it seems MS wants everything to be sync'd through zune instead of having removable media ect.
I just hope there is an option for at least 32GB soon, but I would definitely prefer fast and efficient NAND storage like what the Focus has.

The N8 does not have 64 GB storage. I'm pretty sure it's 16 GB + SD Card Slot, just like Galaxy S phones...
Yep, just checked... 16 GB Internal Storage with support for up to 32 GB SD Card.
I used to install all my apps to a Class 2 SD Card in Windows Mobile as well as put all my music and videos on it and never had any issues with performance.
In any case, that's not a factor. SD Cards for for media storage, and you can get a high class card if you need it. As long as the phone has a decent amount of internal storage it's not gonna be a problem
I just rather the phone come with at least 16GB internal so I don't feel like I have to splurge for an expensive big SD Card on top of an already expensive device. Plus, it makes a lot of sense...
With the way WP7 works with SD cards, they're better off putting in a large amount of internal storage. SD Cards are how swappable storage and when you make them unswappable it defeats the purpose of even having the slot - especially when you have to factory reset your phone everytime you want to change it (which means you're need to get the biggest card possible off the bad, or deal with a ridiculous inconvenience later on if you want to upgrade it)...
Also, until Microsoft mandates storage types most manufacturers will continue to use SD cards. It allows them to spend VERY little money putting lots of storage whilst charging consumers a ton of money simply because there is a lot of storage there... SD Cards are ridiculously cheap compared to NAND, but you'd never know in the pricing...
Also, if an SD Card goes bad, the phone is much easier to repair than another with a NAND chip soldered in. It's as easy as opening it up, replacing that card, and factory resetting the device then sending it back... That can potentially lower support costs as well

Looks like the 64GB N8 was an april fools gag...I fell for it :O
I wish my Focus had 16GB thats for sure. I chose it as it had the best form factor, best screen, and Samsung's Chipset/Memory was also top notch. Why they chose to only put in 8GB is beyond me.

[Q] UHS conflict with S3 & Note2?

Does the UHS (Ultra High Speed) feature of some Class 10 MicroSD Cards mounted in Galaxy S3 or Note2 phones sometimes decrease the reliability of those cards, leading to pre-mature card failure?
See related post at Android Forums.com written March, 2013 by a senior member there:
androidforums.com/5686850-post41.html

ouch!
When posting, is XDA trying to kill us newbies with those ridiculously complicated image verifications? Or is it just because i'm using a mobile phone with a (relatively) small screen? Sound verification is even worse--no visible virtual keyboard! I imagine XDA administrators releasing a pleasant sigh while turning a big knob that makes identity verification increasingly more complex as noobs ask the same questions (like these ones) for the upteenth time. Why can't noobs just suffer in peace? I know, not the correct forum. Nevermind (my 2nd post).

UHS conflict with S3 & Note2 (cont)
I'm thinking that maybe there's a tradeoff when designing UHS type MicroSD Cards between backward compatability with non-UHS capable devices (like S3, Note2) and top UHS speed (for UHS-enabled devices like S4, Note3). I'm not familiar with the electronic circuitry--i'm just tired of MicroSD Card unreliability as the industry standard. I'm imagining that in the design process, maybe the reliability of the card when in backward compatability mode (eg, when inserted into S3 or Note2 phones) is necessarily compromised in porportion to the optimization of the UHS circuit included for UHS-enabled devices (eg, for the S4 & Note3 phones). Anybody know anything about that?
Does the 32GB Class 10 MicroSD Card that Samsung recomends for the S3 and Note2 have the UHS feature? That would be a clue. That card is not in stock, hasn't been in stock for awhile at least, so i can't buy it to find out.
Also, why does Samsung not try to sell a more expensive (and thus more profitable) 64GB MicroSD Card to S3 and Note2 owners? That capacity is not in the list of recomended accessories for S3, Note2 on Samsung's website. Is it just to reduce calls to their customer service due to the fact that the default file system on 64GB MicroSD Cards (ie Microsoft ExFat) is not accessible to Android devices (like S3 & Note2) without a third party pay-for app (due to licensing restrictions)? Couldn't Samsung easily format those cards upon manufacture with a Linux file system instead? But i suppose then ur Windows or Mac desktop computer might be unable to read the card without 3rd party software or drivers...
I'm not asking Samsung to recomend the larger-capacity cards, i'm just wondering if this is somehow related to premature failure of some cards, and how it is related. I know some S3, Note2 users love their 64GB Samsung Pro, Class 10, UHS-1 MicroSD Card and it may last years. I'm not denying that some cards from various manufacturers and re-sellers are reliable, but industry average is abysmal (i suspect, don't know) and we can't just blame it all on eBay or China or a bad batch now and again from Sandisk who developed the technology. Something is amiss, maybe several things. I'm sure that if MicroSD Cards were made with the very expensive SLC technology (one bit per cell, instead of two or more bits per cell, or something like that), then reliability would increase, but by how much? I suspect that there may be some simple, cost-effective answers out there already known but not revealed for whatever reasons (it's a conspiracy), or perhaps i just need to learn more about it.
One informative and somewhat related white paper that i did read from NEC Labs is titled, "Revisiting Storage for Smartphones (Kim 2013)". U can google n read it for free, but it's a bit dry.
Please don't post ur personal experience with individual MicroSD Cards here in this thread, but if u read some interesting market analysis/statistics about this stuff, i for one would like to hear it. XDA was once a great forum, but now it's overgrown with the weeds of individual MicroSD Card reliability complaints (and the corresponding refutations: "Don jinx that card! Mine still works great! U musta lived a bad life!") (ha!). Admitedly, not all the bad cards are really bad, and of course proprietary file systems are often to blame: "Every time i move my 64GB MicroSD Card from my phone to my desktop computer or back i have to reformat the card, so instead, when i want to transfer files, i just email myself with the files attached". Ah, thas sad.
I have been writing to Samsung about these things and hope to post more info here if and when it arrives, but don't hold ur breath. I don't feel very well-informed.
