N7 slow down / laggy

I'm under no delusions about how storage works. I just disagree with the way it's marketed. And, in this case, it's even worse, due to the (presumed) IO issues once you get past 10GB.

Latest benchmarks are actually significantly better for reads, for some inexplicable reason, but writes are still sucking hard. Like, sub-Nexus One hard. Again, disable wifi and the scores actually hit the lofty heights of Poor. SQL transactions are so bad they barely even register on the rankings graph.
I've got to admire the contradiction of the thing: a tablet designed for streaming and speed with memory so slow it renders Project Butter pointless; a tablet for company that makes all its money online than only works reliably well when you disable wifi; a powerful multitasking device that grinds to a halt if background tasks try to write to storage.

However the commentards have missed the issue and think that owners are bleating that they only have 13GB and not 16GB or that it runs slow when 99% full.
Please comment on the article that write performance is still a tenth of what it should be, even when the file system is cleared down so that lots of space is free.
So far the only solution is a factory reset.

I ended up restoring to factory defaults and starting again.... I've only installed a handful of apps, but intend to near fill the device with mkv files and see how chrome, currents etc, etc behave. Going by some of the comments above re: I/O, I would expect to see that performance would go downhill again - although Colin's comments that it flies when wifi is off is interesting.. (BTW I'm using stock and non-rooted).
I'm glad you added that to the Register comments, Paul. I think people are getting back on track with it, finally.
Another question for the whole "a factory reset fixes it"---it doesn't really fix it, does it? If you do a factory reset and then reinstall everything back up past 10 GB, won't you still have the same issue? In my experience, it wasn't a factory reset that fixed it---simply uninstalling apps/clearing caches/deleting content until the available storage was below 10 GB.

I've definitely noticed it on JR7. I went back to an old nandroid of JR6 and it's been much better again.
That's using the MoDaCo custom ROM? Was about to root my N7 when I started running into this, so I didn't move forward in the event I need to send it to Asus.

But it is a major fault and if I am honest I am thinking of returning it. Just not good enough. So frustrating.

Just downloading the free Transformer movie does it.
I really don't want to return it, but if it's not fixed soon I can't see any other option.

Thanks to this thread I learnt that I was not alone in experiencing NAND Flash problems with the N7. I purchased mine at launch in July from Tesco and thanks to the info from this thread have managed to secure a full refund from Tesco Direct. I explained the problem and they offered me a full refund without question, they picked up the device free of charge. I guess it's worth asking your retailer to replace/refund the device and point them to the article on 'The Register'. Hope this helps someone...
