LaCie 5big Thunderbolt 2 | 30TB, 40TB (p/n STFC30000400, STFC40000400). For 4K and other bandwidth-hungry workflows, external storage needs to be fast, secure, reliable, and quiet. The new LaCie 5big fits the bill, delivering Thunderbolt 2 speeds for 4K video editing, up to 40TB capacity, and hardware RAID 5/6 for no-compromise data security.
Thunderbolt 2 Speeds for the 4K Era
With Thunderbolt 2 technology, the interface is no longer the performance bottleneck. For the 5big, LaCie harnessed the breakthrough performance potential of the Thunderbolt 2 I/O, squeezing the absolute best speeds out of the hard disks. Add a hardware RAID controller and 7200 RPM disks and the result is incredible, sustained speeds of up to 1050 MB/s that turbocharge 4K workflows, file transfers, and backups.
With this kind of speed, videographers can work directly from RAW files in Apple® Final Cut Pro® or Adobe® Premiere®, get maximum quality from footage, and see edits in real time.


  • Up to 1050 MB/s speeds for 4K video editing
  • Hardware RAID 5/6 with hot swap
  • Dual Thunderbolt 2 ports for daisy chaining
  • Aluminium enclosure and whisper-quiet fan

Notes * Hot swapping will result in data loss in a RAID 0 array.
** These transfer rates were achieved using AJA System Test when connected to a Mac computer via the Thunderbolt 2 interface. Actual data rates may vary depending on operating environment and other factors, such as RAID mode, RAID configuration, and disk capacity.
*** To achieve full interface bandwidth, connect the product to a Thunderbolt 2 port on a computer or device.
**** Encryption software is only available via download and is not available in Russia.
***** These measurements have been made under normal conditions, one meter/three feet from the front of the product. This value may vary with conditions and product configuration. When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one thousand billion bytes. Your computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions and will not be available for data storage.
