Someone actually posted quite a similar thread not a while ago......
Here'e a quick summary:
For my various OpenSource projects, I have deployed a 36TB file system
which is fine and stable running 24/7. Additionally at home I use 4TB
(2x 2TB) + 8TB (2x 4TB) on a machine with 4GB RAM.... this has been up
for 3 years with minimum reboot!
- this system gets pretty hammered as lot's of front ends for my
OpenSource stuff run off there plus I transfer large amounts of data
10's of GB's often between systems. For web stuff I get round
20,000-30,000 hits from various places on that particular box and it
handles perfectly unlike my crappy Cisco 857 router - will redeploy a
uni-socket server running OpenBSD for this one.
