Is news so important to you that you would put it on a filer? That's one thing I stick to JBOD... price out two terabytes of usable storage on 50GB or 72GB drives in decent enclosures over U2SCSI or FibreChannel, and compare it to an F760 with the same amount of space. If you're concerned with performance of millions of small files, switch to a different storage model... it will almost certainly be cheaper than a big Netapp.
