Not sure which Mac or storage system you need, or how to configure it, plan for backup, etc? Consult with Lloyd.
Early 2018 is an exciting time for Thunderbolt 3 with many new products emerging, particularly SSDs which deliver speed and convenience never before possible, right on the desktop.
The about $1999 LaCie Bolt 3 is a 2TB Thunderbolt 3 / USB-C SSD which internally contains two M.2 PCIe SSDs striped together (can also be used in separately or in RAID-1 mirror mode). It maxes-out the Thunderbolt 3 bus for large reads, which is as good as it gets.
The LaCie Bolt 3 competes with the OWC Thunderblade, which I will be reviewing soon.
Build quality is top notch.
