The Glyph Technologies Triplicator Backup Device 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. It is compatible with Windows and Mac computers.
