LaCie 2big Dock 48TB External RAID Hard Drive HDD - Dual Thunderbolt 4 Ports and USB4 Compatibility, for Mac and PC Desktop

Lacie 2big Powered By Seagate Ironwolf Pro enterprise-class drives delivers reliable storage solutions for demanding projects. you can either combine both drives together for more storage space or opt for more data safe mirroring option. the unit has an additional TB port (for daisy chaining), a USB and high speed Card reader slots. One thing to be careful while purchasing this unit, is that you must ensure if its the older thunderbolt 3 or the newer thunderbolt 4 device your getting since both can be easily mistaken. I received the wrong older model and had to contact the seller. They attended quickly and offered assistance to resolve the matter. I'm happy with their customer support service. As for the unit, its my 2nd Lacie 2big. both are rock solid and reliable.
