System Overview
LaCie 6big and LaCie 12big are desktop hard drive enclosures that house up to six and twelve 3.5-inch hard drives, respectively.
Enclosures shipped with hard drives feature high-performance Seagate enterprise-class hard drives. In case of hard drive failure or, the need to expand storage capacity, each individual hard drive is hot-swappable and field replaceable. New or replacement hard drives must meet the following minimum requirements:
- SATA I or higher
- 3.0Gb/s or higher
- Spin up to 7200 RPM
- 64MB cache or greater
Storage management
LaCie 6big and LaCie 12big storage is managed by the software utility LaCie RAID Manager. See Software for more information.

- Status LED/power button: The LED indicates that the device is powered on and provides status signals (see System LEDs). It is also the power button. A short push spins down LaCie 6big’s/12big’s hard drives and places the system into idle mode. A long push is only for emergency use since it cuts power to the system without spinning the hard drives down. See Operation for more details.
- Swappable hard drive trays: Hard drive trays can be removed to replace failed hard drives. The LaCie 6big and 12big hard drives are hot-swappable.
- Hard drive status LEDs: Indicates hard drive activity and health (see System LEDs).

- Power switch: Push I to power on the device. The device must also be connected to a computer that is powered on.
- Thunderbolt 3 ports: Use the included Thunderbolt 3 cable to connect to a Thunderbolt 3 port on your computer or other Thunderbolt 3 devices. Since the ports on the LaCie device are not preconfigured with specific roles, you can use either port as the host (connected to a computer), as part of a daisy chain (connected to other compatible devices) or for power delivery to compatible devices. See Connect your LaCie 6big/LaCie 12big Thunderbolt 3 and Daisy Chain.
Note: The Thunderbolt 3 and USB 3.1 ports cannot be used at the same time.
- USB 3.1 port: Use one of the included USB cables to connect this port to a USB port on your computer. You can connect LaCie 6big/LaCie 12big to a computer with a USB 3.1 (USB-C) port or a USB 3.0/USB 2.0 (USB Type A) port. Transfer rates vary by the connection type.
Note: The Thunderbolt 3 and USB 3.1 ports cannot be used at the same time.
- Firmware update button: Updates to the USB firmware are posted on the support page to enhance your product. Only press this button when following instructions to update the USB firmware. Use a small pointed object such as the end of a paper clip to push the button within the enclosed space.
- Power input: Use this port to connect the power cable. Only use the power cable included with your LaCie 6big Thunderbolt 3 or LaCie 12big Thunderbolt 3. Attaching third-party or other LaCie power cables with incorrect voltage can damage the LaCie 6big Thunderbolt 3 and/or LaCie 12big Thunderbolt 3.
- Kensington™ lock port: Use this port to physically lock LaCie 6big/LaCie 12big to a desk or rack.
