My first boss was a real fanatic about backups, and taught me to always compound the odds in my favor. MIL-spec ruggedness is a way of doing that and, along with the availability of lots of space for files, made it pretty easy to pick this drive out of the many other models available on the market.

I had to salvage all my files from an old external drive, before it was obsolete. I bought this online at johnlewis.com, and picked it up from the store's collection point at Brent Cross, NW London.

Got this because my old backup drive died. It works really well and fast. It comes with a USB C to USB A so you can use it on any computer. It comes loaded with a setup tool that is really helpful to create a shared partition that works with Windows.

Best hard driver ever and really safe

Works really well, does what it's suppose to and looks really nice and clean.

simply brilliant. very fast. great qualitysimply brilliant. very fast. great quality

This mobile drive is compact yet very tough. The design is well thought out for protecting data on the drive - both electronically, by encrypting and password protecting files, and physically - rugged metal case and strong rubber bumper. The USB3 speed is great. I couldn't be happier.

Nice looking and rugged feeling hard drive. Using it mainly to store 4K videos to be edited on a MacBook Pro. Despite the number and size of the 4K files - there was no lag in imports and exports to the LaCie. Very happy. The rubber grip makes it easier to handle without fear of dropping it.

I can't believe such a high quality product was available at such a reasonable price. It holds TONS if data and is very quick. Could not ask for more.

The LaCie Little Big Disk Thunderbolt (1TB SSD) ($999 list) is the latest version of the aluminum-clad thoroughbred series of external solid-state drives (SSDs), keeping a single user's data easily accessible at a moment's notice.

Expensive per GB; Requires included AC adapter for use (not bus powered).
