[Asus  Eee Pad Transformer Prime] TweakerL:
So, originally like most people - at least I think most people - I thought that the whole I/O problem has been caused by software issues. However, the more I read, and please correct me if I happen to be wrong, it seems as though the problem is at least in part a hardware issue caused by storage solution chosen to be installed in the Transformer tablets (and possibly the Nexus 7 as well). Read Here for some extra info... (Yes, it's mainly about the Nexus 7 but the articles connects it directly to the transformer tablets if you read it).

Now, according to that article, and to my own experience, it appears that while for the most part the Prime, as well as the Infinity and the Nexus are all amazing devices otherwise, because of this unfortunate bottleneck caused by the I/O performance (namely and most importantly random write speeds), nobody has actually been able to get anywhere close to the full potential of these devices.

I've run some benchmarks on my Prime, and my random write speeds sit below 0.25mb/s, which explains why doing anything on the tablet while something is being downloaded or updated generally causes ANRs. So, onto my suggestions... I've been reading on it, and it appears to me that there are a few MicroSD cards available on the market that are capable of up to 1.5mb/s random write speeds. Which is roughly 6 times more than what I can achieve on my prime. Because of this, I can't help but wonder, what if I had one of these MicroSD cards and all the storage that usually gets stuff written to (app storage, cache, etc...) was mounted to this MicroSD instead of the internal storage?

So far, I'm led to believe, due to personal experience (I got one of the GPS dongles provided by Asus, and while that's not a perfect solution I must say that Asus did the best I could realistically expect them to do in order to deal with the situation.), that Asus will do what they can to stand by their customers (and I know I'll get flamed by an angry mob for saying this, but I understand why as a developer, sometimes you can't get too close to the community because as you make yourself more available and start making promises and giving ETAs the community tends to go a bit crazy when their demands aren't met.).

So what I ask now, is for Asus to look into this possibility, and to test whether using a MicroSD capable of higher random write speeds could solve the I/O problem, and if doing so can solve the hardware part of the problem, I believe it would be a fair request that Asus provide customers with the MicroSD cards the same way they did with the GPS Dongle (they aren't actually very expensive about $30 retail) and with a firmware patch that moves the appropriate mounts to the external storage.

On a side note, I personally have one of these high performance MicroSD cards, and in every benchmark app that I have used so far that's capable of testing both internal and external storage write speeds, the results for my external storage are always 2-5 times higher than the results in internal storage, leading me to think that my theory has much merit.

Now, if anybody has a script, and I'm sure one's available as I have seen them somewhere before but just can't find them at the moment, that can mount all the important stuff to the external storage, I'll gladly test it and report to the community and to Asus whether performance has increased.

Now, I hope that this thread can be kept clean (no BS/flaming/etc) so that it can actually accomplish something useful rather than being just a cesspool of pointless trolling
