SDHC with Wizard?

Hi,
Although this question has been put up many a times but I don't see a conclusion in any of the threads. Can someone give a finite answer to the SDHC support in Wizard? (Y/N)?
Did anyone try this:
http://forum.xda-developers.com/showthread.php?t=345038&highlight=sdhc+patch
Thanks.
WIZA200 (HT622)
TNT 1933 ROM

Yep, tried it and it didn't work. I couldn't even read my existing 2Gb SD card
There seems to be conflicting information - some say it is just a driver issue, others say the Wizard's hardware can't support SDHC. I have searched and searched and it does seem that either the Wizard's hardware can't support SDHC or there simply hasn't been a driver written that supports it. Either way it doesn't work currently.

Depends from what you really want to achieve bottom line .. I have a 4GB card working perfectly smooth. Not sure, but I guess it is not a SDHC card. So is it really the SDHC you are looking for, or rather "just" a large sized card?
If you want I could check for the supplier.

Are you talking about 4GB mini SD Card? where did you get it? I am not talking about SDHC. I got 4GB HCSD but I never have a change to make it works with my Wizard.

Yes, bottomline is that 2 GB is not enough and I am seriously looking for high capacity cards. I came to know that all the cards above 2GB are SDHC (as on sandisk and sdcard.org websites).
If you know of a 4 GB card that is non-SDHC and is working well, please do send me the supplier details. I am based in India so need to check if he can ship overseas.
Thanks.

Right now I have an authentic 4 GB SDHC card from Transcend.
Till now I have tried all the patches/drivers available here for SDHC but couldn't make this to work. I even checked after formatting the the card in FAT16.

Here is the one I bought. It is NOT SDHC, but has a 4 GB size. Unfortunately this link is to a German eBay shop:

Hope this will help you in possibly finding a supplier in India!

Sorry for the huge link, I dont even know if it will work so lemme know. If it does, all of that guy's 4gb mini-SD cards are non HC. From what I have read, "Topram mini-SD 4gb" cards from a certain batch are non HC and work with the wizard. I ordered one from the person in the link and it has been working fine so far. Hope this helps.

Is there a difference between the cards themselves or is it just the formatting?

the formatting and the hardware logic is different. there are differences internally, but externally they appear to be the same.

IO Troubles what's the progress on that?

After finally being able to unlock my bootloader (for those still having trouble: I mailed asus directly about it and after the basic tips of factory reset and stuff they elevated my call and suddenly I was able to unlock.. not sure if my mails helped but was quite funny it happened the day they elevated it), I started investigating more on the capabilities of this sweet device. Now basically I wanted to do more with PDF's and well here the IO troubles are a pain So yeh.. is there a firmware team working on it? or is this something we'd have to wait for on asus?

Completely on Asus's side. There is nothing we can do as users without either a better unlock or using flakey hackish workarounds to reduce (tho not eliminate) the problem.
Basically, consider this: You have a car with a corvette engine in it with the transmission of, say, a Ford Model T. You just can't get the power to where its needed.
The Tegra3 chipset is kind of like that. Boatloads of horsepower but it struggles to get that power to the wheels and you get lots of ANR's. Asus needs to find a way in the kernel which is locked tighter than Fort Knox to streamline the process while keeping stability up.

If you want the best experience for pdfs then download perfect viewer and the pdf plug in from Google play and all your io issues will be gone.
Seriously try it. No other pdf viewer can compete.

Since you're unlocked I suggest you try the Zeus rom v4, just out. Very fast, makes a big difference.

Odd, because my Tegra 3 HTC One X is significantly faster than both my TF201 and TF700. Either Asus had botched optimizing the kernel or they cheaped out on the internal memory, yet again.

Well part of it is the scheduler which far as i know (i could be wrong) is in the kernel. A custom kernel def could help tho we dont have access
Another problem could be cheap memory chips for the internal storage. Chances are they went with the lowest bidder and got crap quality. Why put class 2 chips in a device that demands class 10 or higher? WTG Asus. (speculation on this one, tho it makes sense)
Also, other teg 3 devices could run faster but what other things factor into it? Smaller resolution screen = much less pixels to update. Possibly faster / greater quantity of ram. Different kernel and rom optimizations. Different power managment settings. Different clock settings. Different voltage settings (chips can be undervolted and overclocked with varying results) LOOOOTS of factors go into "why X device might go faster even with the same processor).
Picture this: A semi truck and a smart fortwo are given the exact same engine. Which will go faster? The smartcar. And yet if this were android you would still have people say "But its the same engine! why does the semi go slower?" Same principal.

Well ok that said, (also just speculation) wouldn't "most of the IO troubles" be solved by one brave guy who posts a "how to safely break open your $700 device and replace the internal sd card" ?
My first tablet was a ****ty dropad I picked off some chinese site for $100 .. it's internal memory was in fact a ****ty 4 gig card .. I believe it was class 2 even.. so some brave guy cracked it open and wrote how to do this. So I ended up doing the same and indeed solved alot of problems.

It would have been great if Asus chose to use an internal SD card!! Can you imagine the HACKABILITY?!?!?
Unfortunately no internal sd card in the infinity: http://guide-images.ifixit.net/igi/MHZKnMyJmRCfQwPn.large

oh well darn
tho not entirely sure what I am looking at I do recognise some chips on that pcb

Based on the ifixit site these images were taken from there are memory chips there:
Hynix H26M64002BNR e-NAND and 2x Elpida memory J4216EBBG-GNL-F
Do you know which one is the culprit often mentioned as "cheap" RAM and partly the cause for the IO issues?

I'm not a developer but closely follow the xda forums on all my devices and have learned a few things (but may not use correct terminology, so bear with me). It seems that when we have kernel source code (and ASUS TF700 binaries), kernel devs can use the linaro tool chain and produce some really amazing kernels which, together with the rendering enhancements in Jelly Bean, will improve performance a great deal, across the board. The GPU can be overclocked.. there's a lot that can be done with the hardware we have...just need source code/ASUS TF700 binaries.

Hmm ok so judging by a quick lookup it's comparable to a class 10 flash? (quick google tho, so I might be WAY off )

There's more information here: http://www.anandtech.com/show/6073/the-google-nexus-7-review/6 including some benchmarking of the Infinity, Nexus 7 and Samsung Galaxy Nexus. It does look like Asus cheaped out on the NAND in their tablets.

I'm not so sure that the problem lies in "cheap" components. I've been digging through the kernel source and the only NANDs that keep popping up are:
00491: case 0xD5: /* Hynix H27UAG8T2A, H27UBG8U5A or H27UCG8VFA */
00492: case 0xD7: /* Hynix H27UDG8VEM, H27UCG8UDM or H27UCG8V5A */
first 3 are from Hynix's Q4 2011 Databook and second 2 from the Q2 2009 Databook (couldn't find the last one) and none of them match the one seen in the teardown http://www.ifixit.com/Teardown/Asus-Transformer-Infinity-TF-700-Teardown/10306/1
(Sorry, formatting got ruined so I did a quick -- insert to make it readable)

I honestly think that ASUS is just kicking these things out the door as fast as possible and not putting enough time into actually working on or even attempting to co-develop drivers. They just slap in a reference driver that works and go. Even the JB source for TF300 has the exact same NANDs referenced.
After seeing this I started looking through the Prime forum and see the devs there had came to this conclusion months ago. It seems we've put to much faith into this company. Yes, they've set the bar a little higher in terms of hardware, but they apparently are unwilling or unable to make it work well

As mentioned before with proper source code developers could fix a lot. We need to push for source code.
The io performance has something to do with the synching between tegra and sqlite. It's so bad or it was on tf201 that it can't possibly be all hardware as a cause.

Which SSD Cards for DS

Which SSD cards will work with and are best suited for the Desire S?
At the moment I have a 2Gb Scan disk that came with the phone and I want to get a 32Gb if preferable but want better speeds.

It isn't an SSD (Solid-State Disk) card - it is a microSD card. HUGE difference
From experience - and what I seem to remember being posted here before - there is no real point in going above a Class 6 card. I am running a Sandisk 32GB Class 4 and it is more than good enough for storage, music, photos etc.

So getting a class 10 won't help with access/write speeds? Is there any specific reason as to why you say so?

Have a search through the DS forums as I can't be bothered to do it for you. I seem to remember that anything faster than a Class 6 is wasted as the DS can't actually read/write any faster than that.

It is pointless to have such cards in a phone, who needs to handle small files randomly. Class 10 and 6 are designed to write/read large files quickly (photography).

Samsung Class 10 MicroSDHC 32gb or Sandisk SDHC 64gb?

So the main question is, is there a big speed difference between these two memory cards? I tried some searching but didnt find any good numbers to compare.

The only thing you shoud consider is that I have not been able to get my 64GB Sandisk to be recognized in CWM. I had to revert to my 32GB Sanisk. Also I was having I/O locking that would cause the device to reboot. Unfortunately I have not had a chance to fully test this, but since I have removed the 64GB card I have not had any reboots. I also switched over to CleanROM 2.2 and 2.3 at the same time, so I am not sure what has fixed my reboot issues. I am planning on spending a little more time to determine what the root cause was.
I know it does not answer your exact question, but this has been my experience with the 64GB card.

They are the same speed rating at 30Mb/s, but many ppl reported that the samsung's speed is not consistence. So I would recommended Sandisk.

[Q] katkiss and ram expander

Hello everyone,
I have a question about ram expander software - it is said there can be boost in performance if I use it. Just wondering is it worth it? I installed latest Katkiss based on Android 4.3 on my tf101 and it is doing pretty well so far. Maybe someone already has experience.
Thanks!

Hmmm - I think Ram Expansion on Android is just a case of a swap-file being created on your SD card, so factors such as the speed of your SD card will influence how well it works.
There is a discussion on XDA about a Ram Expansion App - mightn't be the same as yours though - here

Thanks for the link, I see there are different opinions regarding the topic but no consensus Looks like I have to check it by myself and then decide. Will see what happens if I use 10 class SD card for that.
