RAID arrangement for mimocan's / one click fixes? - Galaxy S I9000 Android Development

Having seen the various fixes used for the lag issue I was wondering whether it would be possible to set-up some kind of a raid arrangement (e.g. stripe) that would accelerate things even further. E.g. we could create two physical partitions (one on the internal and one on the external sd) and use them in a RAID arrangement.
Just imagine the performance (plus the geekness benefit of having a Raid arrangement in your phone )
Any ideas? Do you think it would be possible?

that would be cool, but i highly doubt its possible.

Sounds cool and it is worth a try!
But... stripe raid works best when both devices are the same. In this case, we would have:
Internal SD Card: Low latency, medium throughput.
External SD Card (Class 6+): High latency, high throughput.
Stripe raid would give us the worst of both, ie. High latency, medium throughput. Probably...
Still worth a shot if anyone can manage to compile a kernel with all the software raid stuff!

It is very much possible - your phone is a linux compter, and it can do anything a linux compter could do. It just has to be done and tools have to be made...

I think you are exaggerating by saying "Anything". Android has limitations.
Anyway, Does Android have any sort of built in raid-management? I have never used raid, but from what I recall you need some sort of raid controller, hardware or software.

I would suspect that Linux will have some open source raid software..

O2 Mini RAM Upgrade

Guy's,
Anybody have any clue on the RAM chip part no. used in this current phone as I would want to do a DIY upgrade to 128Mb or 256 perhaps...
Maybe a detailed high res picture might help too...
changing the chip itself is not likely to be enough imho
chip sellect systems may not be able to access the larger
address span

Bro,
It's enough, RAM used here is plug & play... Trust me...

So I have this idea....

Hi guys
I'm not a programmer by any means, nor do I know anything about developing software, so take this idea with a grain of salt.
The issue I notice from time to time with my PPC6800 is slowdown from lack of ram (or that I haven't closed the apps and they're hogging the ram). My phone only has 64mb....so this got me thinking.... Vista has a feature called Readyboost which uses any flash based USB key to act like virtual ram (or a pagefile).
SO, how feasable would it be to create software that would coule read/write off the microSD card as if it were ram? Basically a MobileReadyboost as it were.
Discuss amongst yourselves =)
PS: Forgive me if something like this already exists for our platforms...but I haven't seen it.
SD cards read and write slow...
What if deleating the extended rom partition (located in ram, right?) and using that for a pagefile instead?
most people don't seem to use the extended rom when cooking. why not just make it usefull?????!!!!!

SD cards can be slow, but there are some models that are faster. Granted they cost more and are a little harder to find, because they are aimed photo people. But yeah.
extended rom in cooked roms is generally used for extra storage anyway so it isnt like it isnt being used
"SD cards can be slow, but there are some models that are faster. Granted they cost more and are a little harder to find, because they are aimed photo people. But yeah."
problem is that today it's not just sdcards which is the bottleneck the sd interface itself on the cpu is slow too

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.

Fall 2011 - Windows Phone 7.5
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...
Low end devices would stay as WP7 and WP8 would support the high end features... Microsoft has already said this is the strategy.
^ 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).

I have no use for a FFC, and TBQH, I don't even want a phone with a FFC. I'll take an extra 8GB of space instead of a FFC for same price, plix...

Agree, and Mango needed to be coming out now, not in six months. They really dropped the ball releasing basically a feature phone in the smartphone market.

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.

Internal SD card question

Hi,
I just got a brand new Galaxy Nexus and I wanted to ask about the internal SD card.
It is to my understanding that normal SD cards die over time with use (if you keep copying files on and off it).
I want to watch heaps of videos on GNex and I was wondering if the internal SD would 'die' quicker if I kept on copying video files onto it over and over again.
Thanks for any help.

Its not an internal SDcard, its a virtual path on the internal storage that's an "SDcard". I highly doubt you'll ever read/write enough on the flash storage to negatively affect it in the phone's lifecycle.

Challenge Accepted... just kidding,
Thanks
Theoretically, yes.
And I actually posed the same question about Swap and Zram to my Kernel Developer.
I got a fairly long post about how (again, theoretically, yes) it may impact after years of use...but not to the extend that I shouldn't be able to complete my two year contract or anything similar.
While this was my original assumption, the reassurance felt nice.
That...and have you ever had an SDcard **** out on you?
I never have. Nor have I heard of it happening to anyone I know (aside from 1/100000000 people online...you know).
Tl;DR
Writing constantly to the internal storage CAN impact performance negatively.
But it'd be an extreme case to have this impact you during the years that you own the device.
If I'm not mistaken, current generation MLC NAND starts to degrade after around 10,000 writes cycles, so that should last you quite a while .

No but a friend who does photography has had a 2gb one die a while back and I've had a mechanical hard drive (although this is totally different to flash storage ) crap out on me just a few days ago.
This is my first smartphone so I want to be cautious but I also didn't buy it just so it would sit there doing nothing
Thanks for your advice, hope I can make this phone last a few years.

[QUERY] Page File on your SD card?

I realize this may be a NO and probably highlights my utter lack of knowledge of the Linux operating system, but I recently purchased a 32GB, class 10 SD card for my Epic. Was wondering if it would be fast enough (or if the bus speeds are) to effectively increase the RAM of my spiffy little Epic.
Just curious if it can be done and also if it should.
Thanks!
Honestly, I don't think it would be possible. Also, somewhat related is that Windows 7 just included a feature similar to the one you mentioned. It allows you to use USB drives as an extension of the built in RAM. So, considering something similar came out for a desktop OS recently, it's probably not going to happen.
