SD cards and performance

[wizardknight]

While working on my CM7 nook color I came across this thread talking about the random write speeds of SD cards.

What I found was applying this idea to my TP2 made a good bit of difference.

I pulled out Kingston card
Kingston 4gb cl4 taiwan
Random Read 4KB (QD=32) : 1.866 MB/s [ 455.7 IOPS]
Random Write 4KB (QD=32) : 0.016 MB/s [ 4.0 IOPS]

and replaced it with a no name
no name 4gb cl2
Random Read 4KB (QD=32) : 0.900 MB/s [ 219.7 IOPS]
Random Write 4KB (QD=32) : 0.597 MB/s [ 145.9 IOPS]

I went down in class speed, but the over all responsiveness increased I would say. Now this is just what I had on hand. I am on a quest to find a Sandisk card with high random access times now.

This could make a big difference for a lot of people, but I never saw it referenced in the TP2 forums.
