[U,SOLA,GO] Slow NAND / I/O - Sony Xperia P, U, Sola, Go

You have noticed right that Xperia U, Sola, Go is slow at times, and you might wonder why it's like this. It has come to conclusion that this issue is related to our phones internal memory (NAND) and the issue is that it's slow and unreliable.
The Sony Xperia U, Go and Sola uses the same NAND memory, the sdin5c2 and is made by Sandisk, here is a datasheet of the NAND:
http://omapworld.com/iNAND_e_MMC_4_41_IF_data_sheet_v1_0[1].pdf
I have done some benchmarking of the NAND memory now, and my theory of it being slow seems correct, especially when it comes to the random write and read speed, which needs to be good for the device to operate in a good way,
Here is some of my benchmark results:
Xperia U
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Nexus 7 (Comparisment to see what's normal):
Seem's like Sony have been chosing a cheap and unreliable NAND memory, as these benchmark results really shows how bad it is. Also the slowdown of the phone while downloading apps and such shows it also.
Heres my task for all Xperia U, Sola and Go users, go to the Play Store and download the app called AndroBench and do a full benchmark, then post a screenshot of the result here so I can get a wider amount of tests so that we can see if it's just my NAND or everyones. Also post which device you use and what rom you use, as that might be useful.

This is the result of my XSola

Pretty much what I did get, so that means my theory might be right.

Here's mine
Xperia Sola AOSP 4.1.2 ROM
looks like you're right.

Yeah, look's like it, those values aren't normal compared to other devices.

But I have also a Acer Iconia B1 A71 Tablet and it has nearly the same result But it's 100-120€ Tablet so I think it's acceptable Will ask my brother if he can do it also on his Xperia Z
So my bro got following result on his XZ:

You should figure out why fps is not stable and scrolling is laggy.
Thats main problem.

Actually that can be caused by slow NAND, as it takes more time to load animations and text and such.

Xperia P

Yeah, almost all benchmarks on XU, Sola and Go gets the same because of the nand.

NAND is really slow than Nexus but Nexus have more prices than us bro

It lags? I run aosp jb without any lags. Compared to my nexus 7 its pretty fast.

By the looks of the Xperia P screenshots Xperia P have another version of the NAND which performs better.
