I can attest to this. I hear from a reliable source (manufacturer)
that 2TB 3.5" disks will be out no later than first half of 2009
(possibly even sooner, or at least 1.5TB). I currently use 1TB disks
with a Geode LX based motherboard for SATA RAID and I plan on
upgrading/consolidating to larger sizes once they become available in
the market. 64-bit is not an option for me on this hardware.
