Overview
Plugging one Thunderbolt cable into a Mac, PC or USB-C iPad brings this LaCie RAID online as a storage hub. Two Thunderbolt ports let you chain further devices, and the hot-swap drive bays allow a failed drive to be replaced without shutting down.
Thunderbolt daisy-chaining turns the storage into a desk hub for monitors and other drives. Spinning hard drives cap speed below SSD levels, and its weight anchors it to the desk.
Who it's for
Editors and photographers with Thunderbolt machines get huge capacity and chaining in one box. Travelers should choose a portable SSD.
Pros and cons
- Thunderbolt 4 daisy-chaining
- Broad USB4 and USB compatibility
- Data recovery service
- Heavy desktop unit
- Hard drives slower than SSD
- Cables in box not listed
Performance notes
Drive speed, not the Thunderbolt link, limits throughput, since the bus is far faster than two spinning disks. Daisy-chaining shares bandwidth across connected devices. Enterprise drives sustain long video transfers without throttling.
