LaCie has announced the 5big Thunderbolt Series, a massive new five-bay RAID solution. With five 7200rpm/64MB cache hard disks preconfigured in RAID 0, the LaCie 5big offers capacity up to 20TB and speeds up to 785MB/s.

The LaCie 5big allows users to create custom RAID configurations. According to the announcement, users can create a lightning-fast volume with three disks in RAID 0 and a safe volume with two disks in RAID 1. The disks are hot-swappable, so they can be replaced without switching off the device. Additionally, the LaCie 5big can be used as a JBOD array.

Also, according to the company, the LaCie 5big’s advanced dual cooling system ensures long-term reliability. This “ultra-quiet” cooling system consists of three key components: an innovative heat-dissipating aluminum casing, a Noctua cooling fan, and jumbo heat exhausts.

The LaCie 5big is available now with pricing starting at US$ 1,199 for the 10TB model and US$ 2,199 for the 20TB model. The LaCie 5big is protected by a three-year limited warranty, which includes web-based resources, in-house technical support, and repair/replacement.
