You probably want to remove your order number from that post. Some unsavory people might do something bad with it...

By the way, I got that email a few days ago (exactly one week after I placed my order). How long ago did you place your order? If a week, I assume it was an automatically generated email and doesn't mean anything.

Also, note that your order has probably gone from "In Process" to "Back Ordered" which isn't exactly a great sign.
[Asus Transformer TF700] californiarailroader:
Thanks, I edited it out.

"If this is a "special

order" or a "pre-order" item, please be aware that this email is

automatically sent on all orders that are waiting for stock to arrive.

There is no need to contact us for a substitution on pre-orders or special

orders."

I've gotten that from them before on pre orders, it usually comes not too long before they start getting stock in. I placed the pre order on July 1st.
[Asus Transformer TF700] d14b0ll0s:
Yes, I get the lags too while copying (reading/writing) anything bigger. Obviously the I/O issues (I believe it's the average speed that drops then).
[Asus Transformer TF700] apkapkapk:
With these I/O issues (and taking into consideration the ability to root and change I/O scheduler), do you guys think it's still a worthy buy? It's not out where I am though... But I've been waiting a really long time for this. If it's really THAT bad I'm thinking I should just skip this and just get a new laptop or something =/
[Asus Transformer TF700] thephreak99:
As I've said before, its still the best android tab out there. I've been using the infinity for one week, and i just love it. All devices have problems.
[Asus Transformer TF700] apkapkapk:
Thanks dude. All this talk about the I/O speeds being terrible were getting me worried =/ From your experience though, is the lag when writing/reading really that bad? :confused:
[Asus Transformer TF700] agdroubi:
and please can someone explain are these issues software or hardware related? Because if it is a hardware it will be a real failure, but software can be solved.
[Asus Transformer TF700] apkapkapk:
Oh yeah one more thing. How's the battery life holding up for you guys? Say... Some YouTube vids, emails, lots of web browsing, some PDF reading, etc... Does it comfortably last a day? Without the dock that is.
[Asus Transformer TF700] tha_kreature:
If I knew it was hw related I'd return it.

As-is I believe and hope it is sw and can be fixed.

The lack of tools to deep-debug a non-rooted device is what is preventing me from finding out though.
[Asus Transformer TF700] tvachev:
@apkapkapk It is really bad. If you run tTorrent you cannot do anything else. If you download a map, data for a game it is the same .... I hope out could/ would be fixed. Transfer speeds from PC are slow, very slow... See the benchmarks ...It just freezes when you put data on it....
[Asus Transformer TF700] apkapkapk:
Thanks for the input! So I suppose everyone experiences this?

How's the battery life anyway?
[Asus Transformer TF700] Svashtar:
So, you are probably returning it. Because, it is that bad. Just bad. :D
[Asus Transformer TF700] tvachev:
I cannot return it and started to have mixed feelings about it. I thought i can use it as netbook. Now I just hope they fix it in reasonable time ... Judging from experience it won't happen.
[Asus Transformer TF700] tvachev:
Battery can stand for 7 hours if one is browsing and /or reading. I haven't played any games or movies.

I feel ok about the battery. Seems good. It is my 5th day of usage....

I have two mail accounts on push.WiFi on always. Tasker to stop wifi and autosync during the night. Autobrightness does NOT work properly so adjusting it manually.
[Asus Transformer TF700] ian1:
I think its hardware because it only has single channel memory split between 4 cores. Most chips now have dual channel memory split between 2 cores allowing for more bandwidth and I assume better I/O
[Asus Transformer TF700] agdroubi:
is this issue really unbearable? Usually someone transfer data at first, or is it affecting apps and performance?
[Asus Transformer TF700] phonic:
Wow. Based on all of the feedback, I'm not very happy about this expensive "top of the line" tablet. If it's a SW issue, that's one thing. But if it's HW related, that's not going to be fixable. Many of the benchmarks are extremely disappointing.

I was looking for a better replacement for my Galaxy Tab 8.9, but now I'm thinking about just keeping that until a more capable unit comes up for sale. I'm 50/50 about just canceling my preorder with J&R now.
[Asus Transformer TF700] dknotty:
How do all of these low benchmarks affect the tablet in everyday use?
[Asus Transformer TF700] KilerG:
Asus is usually really fast with updates, and they often put out several in a short amount of time. So probably in the next few weeks or so they'll be fixing these I/O issues.
[Asus Transformer TF700] agdroubi:
hopefully:D
[Asus Transformer TF700] phonic:
Unless of course they just went with cheap/crappy hardware, hoping that no one would notice the difference.
[Asus Transformer TF700] d14b0ll0s:
Is it that much worse than 11/19 showed on the pic you attached?

The worst thing are the lags, apart from that the average speeds are not that different than using the same cards in my PC.
[Asus Transformer TF700] KilerG:
They're marketing this as a top of the line tablet that's supposed to be incredibly fast. If the performance is dismal because of poor hardware, then it really isn't a top of the line tablet is it? Plus, the tablet hasn't technically been released everywhere yet, so we'll see how it turns out when everyone has one. The problems sounds like a software issue more than anything, just a change in the kernel and we should be fine.
[Asus Transformer TF700] s300pmu1:
Well, A700 was not claimed to support SDXC, but I know huys who tried it and it worked. Most likely TF700 will work with them, too.

---------- Post added at 08:57 PM ---------- Previous post was at 08:56 PM ----------

Generally, I/O issues are associated with Tegra3 SoC, so it is a HW issue. However, there have been cases when HW issues were mitigated by a SW update (e.g. Smasung Galaxy Nexus volume problem), so...
[Asus Transformer TF700] tommedema:
Thanks, this made it clear for me that I should not buy this tablet (yet).

Now my only issue is whether I should get something else instead or wait.
[Asus Transformer TF700] timrock:
something else like what?
[Asus Transformer TF700] denniegst:
the T3 is based off of the T2 (i think, same single memory channel at least) but I never really heard any complaints about i/o issues with the original transformer. Am i wrong? because if not, then i would think the i/o issues is a software problem.
[Asus Transformer TF700] s300pmu1:
Yes, you are. They were somewhat obscured by the far louder complaints about wireless issues, but there were such complaints and they were not few.

Moreover, the solution of a different i/o scheduler for infinity discussed earlier in this very thread was developed for prime.
[Asus Transformer TF700] tha_kreature:
The post I did was on a pc with a reader not supporting uhs-1 and which I was not expecting to go past 20 mb/s anyway. The read speed of this µSD card is 30 MB/s if used in a uhs-1 reader.

---------- Post added at 01:03 AM ---------- Previous post was at 12:37 AM ----------

I don't see what the problem is in this platform.

I can read from SD cards faster than the TF700 using a 20 MHz AVR microcontroller. With anything from 1200 to 1600 MHz and beyond it should have no issues shuffling this low ammounts of data.

I mean seriously, this has to be the way the sw uses the hw, not a direct HW issue. Take the read for instance. Asking any normal card today what speed it supports, it will get a minimum of 25 MHz. This would allow it to do 12.5 MB/s using standard 4-bit SD protocol.

All cards now adays will suport high speed mode allowing the controller to double that and run clock at 50 MHz. RThis is equal to SDR25 in UHS mode.

Stepping up forther on a UHS card allows 50 MB/s with a 100 MHz clock, or 104 MB/s with a 208 MHz clock. There is also a DDR50 mode allowing 50 MHz clock to deliver 50 MB/s by sending data on both flanks. This is good for interfaces where 100 MHz is hard to generate or similar.

Looking at what happens when I use a benchmark app to write to the µSD card it looks like buffering kicks in and gobbles a lot of data in a short time, then it stalls completely and doesn't seem to release again untill the buffer has been completely emptied or somehting. Untill this happens there is no more data being shuffled and everything just hangs waiting for this. Reading too seems to have a jerky feel to it.

I wonder how much of the write-prep and pre-erase commands of the SD commandset is actually being used. It looks quite appalling really.

I also wonder if it is using the busy signal coming from the card and tying that to a interrupt/controller for fast response and back2back writes.

I doubt it.
[Asus Transformer TF700] jcompagner:
I think we are mixing things up here, my feeling is that these flash I/O is slow, that has not much to-do with the cpu memory controller I think.

That controller problem would be our should be really visible when playing big 3d games because there loads of bandwidth is needed for gpu and cpu, and those games seem to work nicely. But things like accessing the flash is just slow so my guess is that that flash controller is just bad or slow or it's software is just wrong
[Asus Transformer TF700] tha_kreature:
Here's a test for you guys to run:

- Get a nice video file on a µSD card. (400MB+)

- Go to your memory card and select the file, copy it.

- Go to your built in memory Movie folder and paste it.

If it works, try a different µSD card or try remounting card and see if it fails.

I have one standard Sandisk 2GB card where it works and I can copy from it every time. I can also play video from this card.

I also have a Sandisk Movile Ultra 32 GB card and whenever I try to copy data off it I get "Paste files failed". Every few attempts it works though and starts copying, but after a while it fails anyway.

When playing video from this card it gets to a random point and hangs. Happens on both MX Player and VPlayer. Annoying and a dealbreaker in my mind. This has to be a sw issue...
[Asus Transformer TF700] d14b0ll0s:
Ok guys, try BS Player for big mkv files, it has its own HW decoding engine (no bs ;>)
[Asus Transformer TF700] tha_kreature:
Finally a player that works!

Seems to use less battery? Will have to test more...

Exactly got the TF201 mobile dock + TF700T and here's exactly badly manufactured and designed PoS.

It is uneven on both sides top part of the keyboard.

Folded the tablet like a laptop without pressing power button first to screen lock, and unfolded the tablet some time later and actually found it actually launched an app by itself...(on the right part of the screen)

See for yourself!

[Asus Transformer TF700] tha_kreature:
Good news!

I popped the Sandisk Mobile Ultra 32Gb UHS-1 card back in the reader on the pc to see what else I could do to it, and it failed!

Whenever I try to write to it, the drive disappears!

Tried scanning the card and it reports bad sectors/data and dies...

This is good news as it confirms why the TF700 was having such issues playing movies from it. The card is a dud!

I'll see if they can replace the card tomorrow, and then I may actually get some proper readings.

Remember I wrote it looked like the benchmark was running jerky? Well that was probably the card resetting and being handled by the OS repeatedly. Instead of pooping like windows it actually got data off it albeit slowly.

Tested with another 4 GB Sandisk card and a few 2 GB Kingston cards now and it's smooth as a baby.
[Asus Transformer TF700] KilerG:
Windows didn't like your card at all eh? Lol. Get that card fixed, I knew it wasn't the tablet that was giving you those issues.
[Asus Transformer TF700] thephreak99:
Hmmm... I see that someone is saying that the io problem is really bad..

I see the io problem when I'm looking for it, but the last 3 days I've used the tablet for reading the news, surfing, watching movies, Tapatalk and some gaming, and I can't say that the io problem is as bad as some are stating. Got me wondering why the experience of the device is so different?
[Asus Transformer TF700] tvachev:
It is probably the usage pattern. Try downloading a torrent and doing something else or syncing to dropbox with dropsync or copying files from microsd to internal storage ... It was probably my mistake because I thought I could use it as ultrabook of sorts - downloading and uploading stuff.
[Asus Transformer TF700] HoushaSen:
Hi all,

It is very disappointing to see this IO issue with Infinity as I was really looking forward to this tablet, but at the same time at least for me, it is great to find this site and see the issue exist prior to spending $500.

There was a post on Andropolice website someone stating Kernel used by ASUS is several years old, and speculating perhaps that may being the issue. I sure hope that the case.

Does anyone happen to know how other 10.1 inch Android tablet performs on RL Benchmark and Androbench?
[Asus Transformer TF700] Einride:
The Transformer Infinity (and probably TF201 and TF300) is running on Linux kernel 2.6.39. This was the last version before 3.3 was released (3.3 was supposed to be called 2.6.40, but they changed the versioning system before that). So it is old, and I'm pretty sure that the GNex, Nexus 7 and other ICS devices are running som version of the 3.x kernel.

There seems to be a major issue with I/O performance for all Tegra 3 devices, with the exception of the HTC One X (which is a handset). Still, the One X is only bad, not horribly bad as the rest are.

A large comparison between devices here: http://www.androidpolice.com/2012/0...hmark-11-modern-devices-compared-in-13-tests/

Either there's a major issue with the Tegra 3 SoC, e.g. hardware or possibly firmware and/or software, though they certainly have had the time to fix that. I tweeted Anand yesterday, and he had noticed slowdowns when doing lots of IO even on the original Asus Transformer. He asked nVidia about it back then, but never got a reply. He told me he'd ask again, though I doubt we'll get any answer from them this time either.

It's a shame. This thing performs very well in most other cases, but anything short of light IO and it goes into a crawl... :(
[Asus Transformer TF700] timrock:
i'll be cancelling my order, with the IO and camera issues, this might not just be a software fix. Someone mentioned that when they download torrents, the tablet sort of freezes. well, when i download more than two torrents at a time, my xoom freezes, but only for seconds. after those few seconds, everything functions as normal.
[Asus Transformer TF700] mark.m.moran:
Hi all,

As it now looks like JR won't be able to get the TF700 to my brother before tomorrow I might as well get him to go into Bestbuy and pick up the next best thing and bring it over for me. I want a high res screen though so excluding the TF300T (I already had it) what are currently my options and which of those options would you go for?

Cheers,

[Asus Transformer TF700] Dub Tech:
Sorry to hear that Mark, seems like there's a considerable discount to be had from buying the tab in the US!

I think I might return mine to komplett as these lines are really doing my head in. No replies on this forum seem to suggest anyone is experiencing the same problem so hopefully it's just unique to this particular one.

Overall it's a great little tablet and I was very happy with it, though now I'm considering whether the €729 price tag is really worth it.. decisions decisions! :silly:
[Asus Transformer TF700] acdcking12345:
So do we have people who already have the TF700 not happy with it? Are people returning them?
[Asus Transformer TF700] Dub Tech:
When my tablet is in landscape mode I have faint verticle lines on the screen. They can really only be seen when there's a lot of white or generally a light colour dominating the screen. If I apply some pressure to the screen the lines in that area disappear so I'm assuming it's something to do with the gap between the gorilla glass and the screen itself.

Nobody else seems to have the same problem so I'm pretty sure I'll be returning mine this week :(
[Asus Transformer TF700] gerrykv:
I bought one from Komplett, but will be returning it for a number of reasons. It is the US/International version, which means no £ key, only a little Enter key, and a crappy 2 pin adapter. If I am going to spend north of €700, I want to be 100% happy with it, so I am going to wait until the UK/IE versions are out.
[Asus Transformer TF700] acdcking12345:
I hope it is just yours and a replacement will fix that issue.

I have 500 bucks tied up on my order. But I will say I am a bit concerned now that maybe I should cancel the order....

I miss having a tablet but I would be more pissed if the infinity is not as good as we think it should be..

Did anyone get an official reply from ASUS about the IO issues?

I'll want to do a lot of multitasking, e.g. download torrents in the background while watching movies.
[Asus Transformer TF700] agdroubi:
it is important that someone having this tablet to contact Asus about this problem, maybe they are not aware of it, especially that it is not yet released in the US. They may provide a software fix, or a hardware fix before they are out for sale on July 16-20.
[Asus Transformer TF700] thephreak99:
Yeah I have the io problem, but with my use I don't feel that it is shutch a huge problem. I don't use it as a laptop to dl torrents, and transferring files feels ok. The camera shutter sound is only apparent if you are recording and click the screen for a manual focus point. Something I have never done before anyway. I just use the regular auto focus.

Yeah I can see that someone thinks this as huge problems, and I don't deny that they exist, but on the other hand I don't think they are deal breakers.

Take torrents. Torrents generate a huge load of io operations. My personal thoughts are: I don't expect a table to run torrents flawlessly. It's a tablet, not a full sized computer. But of course, it would not be bad if I did run it smoothly.

And on the other hand, I think that the chefs in here are going to make superb custom roms that will smooth out the kinks we find. And Asus have already uploaded their first fixes for download, so hopefully they are going to keep uploading fixes.

Maybe I'm just an optimistic person, but right now I just think that people are posting stuff in this thread that is way out of preporsons.
[Asus Transformer TF700] acdcking12345:
To The phreak99,

I would not be doing any torrents on mine either. Worst case for me is maybe copying files from the Microsd card to the internal memory. I dont care if I have to wait on it. I don't normally multi task much anyway. So I say let's see when we actually get the thing in our hands before we assume it has big issues. :-)
[Asus Transformer TF700] tha_kreature:
Got a new 32GB UHS-1 µSD card today!

This one seems a tad faster on the PC and I assume that is due to lack of error...

However, popping it in the tablet makes the SD icon show up for a fraction of a second and disappear again!

Can't use it!

Anyone else experienced this?

Tried NTFS, Fat32 and ExFat. Even limited it to 32k clusters. Still no joy.

Edit:

According to dmesg it detects card as UHS DDR SDHC.

Then it fails reading sector 0 with error -84.

Same goes for sectors 1-7.

Card status 0x900.

It then retries before trying to read last sectors on card, failing in same way.

Why am I having such rotten luck!
[Asus Transformer TF700] acdcking12345:
Have you tried doing a full format on it and even do a scan on it to verify that it is stable?
[Asus Transformer TF700] jcompagner:
this is not really true

2.6.39 was release somewhere in may 2011 so more then a year ago (but i have no idea what .x version of 2.6.39 they really use)

after that in Aug 2011 3.0.1 was released so no 3.3 thats way later

I thought that the kernel of ICS was 3.0.x because that was wat i get when i installed ICS in mij SGS2

So i was quite surprised to see that the Infinity still uses a 2.6.x kernel on ICS

[Asus Transformer TF700] timrock:
do you have an android phone that takes memory cards? if so, try popping it in there and see what happens. If its visible, try formatting it using the phone.

this is one of the reasons i wish the tablet itself had a USB port.
[Asus Transformer TF700] d14b0ll0s:
@the_kreature: try different block sizes (say, start with 4k), see the thread on the Infinity and SDXC cards
[Asus Transformer TF700] tha_kreature:
Yep.

Tried reformatting multiple times.

I thought my cluster size was the issue, then filesystem so I tried everything.

Then I installed a terminal app and checked dmesg showing read errors...

---------- Post added at 08:23 PM ---------- Previous post was at 08:17 PM ----------

Good idea!

I tried in phone (x10 mini) and it worked nicely there. To be safe I made it reformat card and it did.

Space available 29 GB.

In the TF700 I get same result though, read errors.

It is definately identifying the card as being high speed. Maby it is bodging the calibration for the DDR? I know it has to calibrate samplingpoints based on it's routing of the signals etc...
[Asus Transformer TF700] reluttr:
So wait.... the IO issue only rears it ugly head when downloading and copying large files? So normal tablet operations "web browsing, gaming, note taking" should not be to heavily impacted?

Also does bouncing the tablet between power-saver, balanced, and performance mode affect the IO speed at all?
[Asus Transformer TF700] HoushaSen:
Einride,

Thanks for the detailed reply. Yes. I remember reading people on this forum speculating the issue being actual tegra chip level. That is the one reason I wondered if anyone with any other android tablet ran these benchmarks. As majority of Android tablet are Tegra based, I assume if Tegra is indeed the issue they all have similar issue except galaxy tab 2, which don't use Tegra.

I agree that Infinity seems a ideal tablet at this time and probably for a while if IO issue was not there. But IO issue seems a major component and it can easily be bottleneck in many of daily tasks we perform...
[Asus Transformer TF700] Jotokun:
Thank you! Nice to see someone reporting on real world use rather than raw benchmark numbers or from trying to put their device under crazy scenarios. Not denying the issue is there, but if it were so bad I think you'd see it mentioned in reviews of the tablet.

The way I see it, the issue is occurring on ALL of Asus's Tegra 3 tablets. Chances are, this includes the Nexus 7. The Nexus will have a good dev community by default, so if it has the IO issue someone will fix it, and that'll get ported to the transformers.
