I have been using flash-based asterisk and it works fine as long as you are 
careful about the maker - SanDisk did not work properly, we currently use the 
RiData flash disk and are happy with it. I have a Kingston Tech flash disk 
that was flaky and finally failed yesterday.

They are not the fastest - running hdparm -tT on them reveals a speed of 2Mb/s 
which is about a third of the speed of 100Mbits ethernet. For call recording 
I usually add an IDE hard drive and make sure that most filesystems 
(e.g. /var,/tmp..) are loaded into a RAM disk
