I remembered this a while ago and decided give it a try again on a new OS. Back when we were on leaks like .109 I was informed that the reason the Storms in the VZW store ran flawlessly on .75 is because there was not an SD card in them. Turns out on .109 it ran almost perfectly for me without one in. But what really is the point having your Storm that comes with an 8g card and not use it, right? So I put the card back in and forgot about it.
For the past few hours I've been running v5 without the SD inserted and it is amazing! Acelleromiter seems faster (unless I'm crazy), I usually sit around 20 -25 of memory (all the themes I have loaded) and now am at ~35.
Turns out the card reader can only read up to class 2 speed. I really wonder why they didn't make it be able to read class 6 speed? Could all the lag in the OS be because the card reader can't keep up?
If your bored, try it out and see if you experience any improvement.
