Thanks for the info Dillon on the pfs naming convention and idea about
mirror stream.
Since you recommended SSDs before I tried to get them from vendors I
know but most of them haven't even heard about it ( I am from Kerala,
India ).

Will a USB Flash drive serve the same purpose?
Something like.

Are they as reliable as the SATA SSD you mentioned. it is available
with the vendors ( 8GB )

thanks
