Humm...I suppose I might consider building a 4-drive 1TB RAID10 from my existing 500GB RE3 drives, and then buy a couple of 2TB Red drives and do a RAID1 for data storage. If I did that I'd end up with 6 drives in the box, 4 of them old, but old ain't necessarily bad. ;-) However that forces me to manage what data goes where instead of just a big, flat RAID1 which is going to be easy to live with. Still, it would probably save some money. > > If you change, do not use ZFS and possibly BTRFS if the system does not > have ECC DRAM.

I'll do a little study but my initial feeling is that it's more money than I really want to spend. Summer's coming. Time for Margaritas! Thanks, Mark
