Looking for a more robust RAID system to go with my office iMac. Used for HD video editing and storage, as well as RAW photo editing and storage. I am planning on the akitio Thunder2 with 4 x WD Black 2TBs. - About how much performance would I lose in terms of r/w by going with a raid 10 or 5 vs a raid 0? I will be doing automated nightly CCC clones, backups are covered. - I also have another thunderbolt 2 bay enclosure, if I jam 2 4tb drives in there can I create a raid 10 from pairing that with my Raid 0 new box? Will the performance be impacted on account of the stripes being connected via thunderbolt, if even possible? Thanks!
