Hardware RAID Simplified

Whether you're new to two-bay hardware RAID or a seasoned pro, LaCie RAID Manager makes it easy to configure any 2big drive for speed, capacity, or data redundancy. It even helps you monitor the system's health via email notifications.

RAID 0 for Performance

Stripe mode: drives are striped together and function like one large drive, allowing maximum speed and capacity.

RAID 1 for Redundancy

Mirror mode: drives mirror each other, meaning data is always the same on both drives. If one fails, the other has your back.

JBOD for Flexibility

Just a bunch of disks (JBOD): drives function independently, offering two separate drives in one enclosure.

Fierce hard drive for intensive projects.

IronWolf Pro enterprise-class drives live inside our latest gen 2big solutions-and they're the secret sauce to sprinting to your goals. Engineered for RAID environments and high-speed 7,200 RPM performance, these drives support workloads of up to 300TB per year-delivering smooth power management, massive capacity, and 24×7 reliability.
