...Z1 for this data. Are there any 2TB drives that will work with ZFS presently? I am willing to take the risk that if I lost a single disk, that they others wouldn''t fail during the stress of a resilver. Write speed doesn''t matter to me. But I need read speeds to supply at least 40mbit/second. I have 8GB of ram on this machine with usually 1 sometimes 2 concurrent reads - so I think prefetch should take care of these read demands regardless if the drive is green. So my question for this vdec is.. What is the best 2TB drive available for a raidz1 configuration? Are the samsung...

Hi folks. This message may be a bit verbose and not as techie as the ones I''ve seen in this list, but describing the scenario will save a lot of messages. Scenario: A building with 17 floors, each floor with 24 offices (totals 408 offices) connected to the backbone through a border switch (1 vlan for each office). The offices can lease bandwidth of 64k, 128k, 256k, 512k, 1M and 2Mbps,
