The Gigabyte GA-H55M-USB3 is a low-cost motherboard that supports the LGA1156 Intel CPU format. This is similar to the Gigabyte GA-H55M-UD2H, but has added support for up to 2 USB 3.0 ports, which are capable of transfer rates of up to 10 times the speed of a USB 2.0 connection. The 5 SATA connectors have also been augmented to enable RAID support in a number of configurations. Otherwise they are the same, with a MicroATX form factor and up to 16 GB of DDR3 memory supported. High definition audio is supported on board and can output through an optical S/PDIF connector, and a number of display connectors are available if a CPU is used that has onboard graphics processing. Both eSATA and FireWire ports are available as well.
