[Q] Increasing SD transfer speed

[9v9]

I have the stock NookHD rooted but was wondering how best to implement a higher cache speed on my SD card (class 10 PNY) If I can use an app I'm hoping it does not mess with the /system, But maybe there is a better way? (A flashable zip in recovery)
The reason I ask is because when transferring media files between the pc and and BNTV400, it either lags/crashes or in other cases moving files already on the card says it will take upwards of 40 minutes to complete! Is this really how they want the Nook to function?
If I'm looking at this the wrong way please let me know!

Part of the problem is that pny SD. They are horrible with these devices. And the stock kernel does a bad job with with external SDs. Not much you can do except get a different card.

FYI, I'm using Trancend class 10 SD (32GB) on Nook HD+ and it seems to work with no issues. http://forum.xda-developers.com/showthread.php?t=1005633 thread has even list of good and bad flash cards (in terms of IO, especially random 4kb IO. You may check this thread choose a replacement.

How likely do you think it would be in the future that we get a custom kernel? Obviously I don't think any of us would be running the stock OS by then either but would it have an impact on the speeds both internal or external? I'm hoping it's not a limitation of the hardware.

I will look into it for future expansion, I just hope that it's the card and not hardware differences between nookHD and the HD+

If you are running CM10 on HD+ you are running a custom kernel. Verygreen builds his own from B&N source. And he customizes it. He says the SD problems seems to be hardware related.

But, because of locked bootloader issues, it may a long time before custom kernels come to stock.
