Just to throw my 2 cents worth into these discussions, I've recently taken
delivery of 34 of the following machines, so around 200 TB total usable
storage. Cost is $6.7k each, so about $1200 per Terabyte.
The local disks exceed 200 MB/sec read/write speeds. As NFS servers we
can get about 100 MB/sec via one network port of 160 MB/sec via two ports
in each box.
SuperMicro H8SSL-i motherboard
AMD Opteron 175 processor
2GB unbuffered ECC DDR-400 RAM in 2x1GB (Kingston KVR400X72C3A/1G)

16 x 400GB Western Digital RE2 disk drives
ARECA 1160 disk controller configured as RAID 6 with 14 + 2 and no hot
spares. The disk controller is configured with one 16-disk RAID-6 set, and
two logical volumes. The first logical volume (20GB) hosts the OS, and
the second logical volume (remaining disk space) is for data storage.
