Summary: I backup my computer daily with this and recommend that everyone I know do the same. It comes in various sizes for everyone's needs. I believe in the reliability and total dependability of LaCie. In Florida, with our daily thunderstorms, it is so easy to unplug the LaCie each morning and then replug each evening for backup. You never, but never, lose your computer.
Summary: As an IT technician, everyday I have to find solutions for my clients and their myriad of systems. Thankfully the d2 Quadra takes a lot of the effort out of this for me. This drive suits differtent platforms and connection types, it’s quick, reliable, easy to configure and so far hasn’t skipped a beat.
Summary: As an at-home web designer I'm always trying to make sure my work files are securely backed up and can be accessed at a moment's notice. With the d2 Quadra, I now know that they are. I can even store my most critical data on the 10 GB of cloud storage (you get it for free with the drive) for added safety and security. Perfect.
Summary: I bought the 1TB version product in the fall of 2010, and I'm a moderately heavy user: a full time professional photographer shooting exclusively in RAW. I regularly transfer large batches of files to and from the 1TB drive and have never had a single issue. Runs super fast with firewire 800, works with my 2011 27" macbook pro and 2009 24" iMac- both running Lion (the iMac ran Leopard before).
Summary: This drive has a good quality all-metal enclosure. It's heavy and quite sturdy. It's also quiet, and has a soft blue light on the front panel. The transfer speeds are good, I use Firewire 800 and a regular backup takes barely half an hour. Good external HDD all around.
