had 3 drives kicked out of my 10-drive RAID5 array.
i want to say up front that i have several 3ware 7504 and 7508 cards
which i am completely satisfied with. i use them as JBOD, and they make
stellar PATA controllers (not RAID controllers). they're not perfect
(they're slow), but they've been rock solid for years.

Great!
We have performed some benchmarking on a 3GHz PC with 2GB of RAM and U320

We started the project in April 2004. Right now I am using it as my
/home/kolya file system at home. We believe that at this stage RAIF is

ftp://ftp.fsl.cs.sunysb.edu/pub/raif/
The code requires no kernel
