Re: Disk access is slowing my Eee PC

I've successfully installed FreeBSD 7-STABLE on my Eee PC 900. Just
one problem. Quite regularly the machine becomes unresponsive. I asume
because of something reading from or writing from the SSD, because it
always happens when the disk activity indicator is lit and it stops
immediately when it's turned off again. Sometimes it lasts as long as
20-30 seconds, just when using Firefox, OOo or similar.
Any ideas on how to deal with this? And just as interresting; what's the cause?
just an idea (i don't have EEE so it's ideas) - EEE simulates IDE drive through flash just like USB drives, adding "mapping layer" to simulate 512 byte sectors writes and to prevent flash wornout.
this is VERY inefficient for random writes on USB flashdrives, and possibly here too.
as long as NAND flash chips won't be directly accessible, and some flash-designed filesystem will be writted it will be like that.
