If you have limited time and need multiple copies of your data, the Triplicator Backup Device with FireWire 800, USB 2.0, and eSATA Ports from Glyph Technologies is an extremely simple go-between for backing up data from your computer to multiple external hard drives all at once. No need to worry about copying data from your computer one hard drive at a time. The Triplicator features three eSATA ports for connecting up to three external hard disk or solid state drives of any capacity.* These drives will need to have an eSATA port. Once your drives are connected to the Triplicator, you can use the Triplicator's USB 2.0, FireWire 800, or eSATA host ports for connecting it to your computer. Thereafter, you can transfer data from your computer to up to three drives in one go. Plus, after data transfers, you can turn off your drives and the Triplicator and turn them all on again without data loss. The data that you saved on the drives will be mountable on your computer in case you want to access and explore it. With a hassle-free user-interface, an included carrying case, and a generous warranty, the Triplicator is an exceptional buy. It is compatible with Windows and Mac computers.

Note:
Connecting drives of the same capacity is recommended if you want to maximize storage space. Instead, if you connect drives of mixed capacities, the Glyph will only transfer data up to the size of the smallest drive
