LaCie 2big Dock 40TB
The LaCie 2big Dock STLG40000400 is a desktop external hard drive with 40TB of total capacity and RAID 0/1 support. It reaches speeds up to 550MB/s and includes CFexpress B, CFast 2.0 and SD card slots plus a USB 3.2 Type A hub port and DisplayPort 1.4. Dual Thunderbolt 3 ports allow daisy chaining up to five devices. It suits creative professionals who need high-capacity storage and multi-device connectivity in one unit.
Upgrade from single-drive storage
This dock replaces standalone drives or smaller RAID enclosures that lack integrated card readers and video outputs. The jump is worth it when you need simultaneous ingest from CFexpress B, CFast 2.0 or SD media while driving up to two 4K monitors or one 8K monitor over DisplayPort 1.4. It is not for users who only need basic file backup without media-card workflows or multi-display requirements.
Desktop setup with hot-swappable drives
The unit ships with a USB-C cable, external power supply and quick install guide. Hot-swappable IronWolf Pro enterprise-class drives let you replace a failed module without tools or downtime. RAID configuration is managed through the included software. Common issues include forgetting to initialise the array before first use and connecting the dock to a host port that does not supply enough power for all peripherals.

Perguntas sobre este artigo
How much desk space does the 3.67 by 4.65 by 8.54 inch enclosure need?
The unit measures 3.67 inches wide, 4.65 inches deep and 8.54 inches tall, so allow at least that footprint plus cable clearance behind it.
Which drive bays are hot-swappable and how do I change RAID mode without losing data?
Both IronWolf Pro bays are hot-swappable; use the rear switch or LaCie Toolkit to migrate between RAID 0 and RAID 1 while the dock stays powered.
When should the two IronWolf Pro drives be replaced under heavy workloads?
Enterprise-class IronWolf Pro drives are rated for high annual workloads; plan replacement after five years or when SMART alerts indicate wear.
