The Good The rugged, good-looking, and compact Thunderbolt-enabled LaCie Little Big Disk SSD offers by far the best performance for a single-volume external drive. The drive can be daisy-chained with up to five other Thunderbolt devices without decreasing the throughput.
The Bad The LaCie Little Big Disk SSD doesn't have the built-in support for any other common peripheral connections like USB or FireWire; it works only with Thunderbolt-equipped Macs, is expensive, and a little noisy. The drive doesn't come with the necessary Thunderbolt cable, either, and offers a limited amount of storage.
The Bottom Line For those who have a Thunderbolt-enabled computer and the necessary funds, the LaCie Little Big Disk SSD makes a decent investment for a compact and superfast storage solution.
LaCie Little Big Disk SSD (240GB)
The LaCie Little Big Disk SSD is the second Thunderbolt-based storage device we've worked with and it's quite different from the first one, the Promise Pegasus R6. If the Pegasus is considered huge, heavy, and offers a ton of storage space, the SSD-based LaCie is tiny and comes with just 240GB of capacity. (There are also hard-drive-based versions of the drive that offer up to 1TB of storage--still much less than that of the Pegasus.)
The LaCie shares something with the Pegasus, however, by supporting only the Thunderbolt connection and offering superfast data transfer speeds. While not as fast as the Pegasus in our testing, it's still significantly faster than any other storage devices of similar configuration, and even faster than some internal solid-state drives.
On the downside, the drive doesn't have any built-in support for USB, FireWire or eSATA. It's also really expensive at around $900 and is a little noisy. Still, if you're looking for a superfast portable and rugged storage device and have a Thunderbolt-enabled Mac, there's no better choice than the LaCie Little Big Disk SSD. On the other hand, if you also need as much storage space as possible, then also check out Promise's Pegasus R6.
