It probably won't be as good as a single drive by itself - realtime replication by its nature is going to be slower..<br><br></div><div class="gmail_extra">For your sort of setup I'd be looking at a ZFS setup, RAID1 or 10 if you can afford it with a SSD read/write cache (easy with ZFS), it will have pretty good performance and lots of extra goodies such as snapshots, compression (very good), checksuming/bitrot detection. That in and of itself with have data redundancy on the one PC.<br><br></div><div class="gmail_extra">If you absolutely need redundancy across two PC's then you could setup a 2nd ZFS server and use ZFS's builtin differential snapshots to replicate to the 2nd server on a regular interval.<span class="HOEnZb"><font color="#888888"><br></font></span></div><span class="HOEnZb"><font color="#888888"><div class="gmail_extra"><br clear="all"><br>-- <br><div>Lindsay</div>
