LaCie 1big Dock 8TB — Thunderbolt 3 Desktop Storage with Built-in Dock
Desktop storage + dock8TB IronWolf Pro 7200 RPMThunderbolt 3 · DisplayPort 1.4Up to 60W laptop charging
The LaCie 1big Dock 8TB (STHS8000800) is a single-drive desktop storage unit with a built-in dock for photographers and video editors working on a laptop: one Thunderbolt 3 cable gives the computer 8TB of enterprise-class storage, SD and CompactFlash card readers, a USB-A port, a DisplayPort monitor output and laptop charging.
Inside is a 7200 RPM Seagate IronWolf Pro drive designed for always-on use. It works with Mac and Windows over Thunderbolt 3 or USB-C, ships formatted exFAT, and adds a second Thunderbolt 3 port so you can daisy-chain more storage or a display.
Before you order: This is a single drive — there is no RAID mirroring, so keep a second copy of important projects elsewhere. Full speed needs Thunderbolt or a USB 10Gbps port; on a USB 5Gbps port it works at up to 5Gb/s.
What's in the Box
- LaCie 1big Dock 8TB
- External power supply (20V, 5.5A)
- Thunderbolt 3 (40Gb/s) cable
- Quick Install Guide
- Rescue Data Recovery Services plan (not available in all countries)
What It Means in Practice
- Plug one cable into the laptop and you get storage, card readers, a USB-A port, an external monitor and charging — useful for an editing laptop with only USB-C ports.
- Laptop charging reaches up to 60W through the dock; heavier 85W+ workstation laptops may still need their own charger under load.
- Card readers let you offload SD or CompactFlash cards straight to the 8TB drive without a separate reader.
- Ships formatted exFAT, so it reads and writes on both macOS and Windows; reformat only if you want Time Machine or NTFS.
What Will Not Work
- CFexpress, CFast or XQD cards — the front slots are SDXC and CompactFlash (CF 6.0 Type I) only.
- RAID protection — a single drive cannot mirror itself; for mirroring choose the 2big Dock.
- HDMI monitors without an adapter — video out is DisplayPort 1.4 and no adapter is included.
- Replacing or upgrading the drive yourself — opening the enclosure voids the warranty.
- Network sharing — it is direct-attached storage for one computer, not a NAS.

Frequently Asked Questions
Will it charge my MacBook Pro?
It supplies up to 60W, which keeps most 13–14" laptops charged. Larger laptops with 96W or 140W chargers will charge slower or drain under heavy load.
Can I connect it to a USB-C Windows laptop without Thunderbolt?
Yes. It works on USB-C ports at the port's speed (5 or 10Gb/s). Thunderbolt-only features such as daisy-chaining need a Thunderbolt port.
Is the data protected if the drive fails?
No — there is one drive and no mirroring. Rescue Data Recovery Services covers recovery attempts, but you should keep a second copy of important work.
What does Rescue Data Recovery mean?
It is LaCie's data recovery service plan included with the drive; it is not available in every country, so ask us before you rely on it.
Singular Expert Insight · Buyer's Guide
The 1big Dock suits a laptop-based editor who wants storage, readers and a monitor connection on one cable. If the projects are irreplaceable, look at the 2big Dock with RAID 1 or keep a second copy on one of our
external hard drives.
✓ Buy it if you work on a USB-C or Thunderbolt laptop and want 8TB of fast desktop storage plus a dock in one unit.
✕ Skip it if you need RAID mirroring, CFexpress readers or network access for several users.
→ Also consider LaCie 2big Dock for RAID 1 mirroring and CFexpress, or LaCie d2 Professional for a simpler single-drive desktop unit.
