LaCie's latest harnesses the power of Thunderbolt 3

The 6big (left) and 12big are two new storage systems from LaCie.

The two can house 6 or 12 (obviously) internal hard drives, respectively, to offer up to 60TB or 120TB of storage space. These drives can be replaced easily via the front-facing bays.

On the back, each system has two Thunderbolt 3 ports and one USB 3.1 Type-C ports. They include a cable for each of the ports.

The 6big is half the size of the 12big, as you might expect.

But it shares the same amount of ports.

It costs half the price, starting at $3,199 or £2,799 for 24 terabytes of storage space. (Australian pricing is yet to be announced, but the UK price converts to about AU$4,900.)

It share the same front-facing drive bays. These bays don't have locks to prevent accidental pull-out.

The 12big is twice the height of the 6big, making it rather tall. At 1.5 feet (0.5 meters) it can topple quite easily.

Since the system is very heavy at 40 pounds (18 kg), it's important not to let it fall.

A close-up of the ports. Unfortunately, there are no regular USB-A ports, meaning you won't be able to connect a USB device like an iPhone to the system.

With twelves drive, the 12big start at $6,399 or £5,649 for 48TB, going all the way to $13,700 or £11,849 for 120TB. (Those prices convert to AU$9,875 or AU$20,715.)

Both systems use Seagate Enterprise NAS hard drives, which are fast and designed for 24/7 operation.
