The LaCie Little Big Disk Thunderbolt 2 is the most expensive 1TB external hard drive on the market. Thanks to its Thunderblot 2 connection, it is also the fastest at the moment. Its price is only for the most demanding and intractable users.

For one terabyte of storage space, the LaCie Little Big Disk Thunderbolt 2 is one of the most expensive external hard drives on the market. A price that can be explained by its performance, and which reserves it for uncompromising users for whom speed is a vital parameter.

With two high-performance SSDs in-house, the new Little Big Disk is by far the fastest external drive today. In addition, its compact yet robust design allows you to take this level of performance with you wherever you go.

If you need to work hard on data like UHD / 4K video editing (especially in this area for that matter), the LaCie Little Big Disk Thunderbolt 2 will make it easy.

The new LaCie Little Big Disk Thunderbolt 2 looks a lot like its predecessor, with its distinctive rugged, all-metal case. On the front, there is the round and blue button, LaCie signature, which also serves as an indicator of operation. At the back, there are two Thunderbolt ports and the power jack. This disc is compatible Thunderbolt 2 but also works with Thunderbolt links. Both standards share the same plugs and cables.

Despite its compact size and embedded technologies, this drive is not self-powered and requires a separate AC adapter. Large, it is about half the size of the set. Yet, everything remains compact enough to be easily transported in a backpack or briefcase.

This new LaCie model comes with plug-in converters for different regions of the globe and a 30-centimeter Thunderbolt cable. A welcome improvement. The previous model was delivered naked.

Flexible RAID And Definitely Mac Oriented

Inside, the Little Big Disk Thunderbolt 2 now uses two second-generation PCI Express 512 GB SSDs, in a RAID 0 configuration, and no longer a simple SATA SSD as in the previous model. You can also switch these disks to RAID 1, for better data protection at the expense of storage capacity.

This new disc is entirely oriented towards the Mac world. First, it is preformatted in HFS +, the file system used by Macs. Which means that right out of the box, it works with an Apple machine if it has a Thunderbolt socket. Then it comes with the Intego Backup Manager Pro for Mac suite. It is a backup software that offers more advanced options than Time Machine.

Technically, Little Big Disk Thunderbolt 2 can be reformatted to work with Windows and the LaCie Private-Public software that comes with it, a security utility that protects access to disk data in the event of loss or theft, is proposed in Mac version and Windows version. However, there is more Mac on the market than Thunderbolt compatible PCs.

Uses And Performances

The LaCie Little Big Disk Thunderbolt 2 worked perfectly during the tests. It only takes a second to appear once it is plugged in. It shares power management with the computer it is connected to. When the machine turns off or goes to sleep, the Little Big Disk Thunderbolt 2 does the same thing. With each change of situation, responsiveness is there, the disc responds instantly.

Tested a 2013 MacBook Pro , which supports the Thunderbolt 2 and uses a fast SSD hard drive in PCI-Express as the main storage memory, this LaCie Little Big Disk is bluffing. In RAID 0 configuration by default, it records at a sustained write speed of 568 Mbps, and a read speed of 643 MB / s. In read / write phase, it holds 500 Mbits / s average.

LaCie Little Big Disk Thunderbolt 2 is constrained by the performance of the internal disk to the computer. If the computer had an even faster internal drive, chances are this LaCie model could have supported a speed of more than 1000 MB / s. To put this figure in perspective, it means that it is capable of to copy the contents of a CD (approximately 700 MB) in less than one second.

In RAID 1 configuration, performance was reduced, but still impressive with 452 MB / s write and 557 MB / s read. No disc has reached these numbers so far. The LaCie also remained silent and did not overheat during testing. No sound escaped the case.

The LaCie Little Big Disk Thunderbolt 2 clearly shows the superiority of the Thunderbolt 2 connection. Its major disadvantage is its prohibitive cost. With such a high price and a maximum capacity of 1TB, this disc is obviously a niche product for those who are willing to pay a disproportionate price for first-rate performance. If you have the money and the need to invest in a Mac Pro for example, the LaCie Little Big Disk Thunderbolt 2 will be a perfect extension. Once purchased, its level of performance will be enough to justify your decision.
