ASRock Z77 Extreme4 Motherboard
These four Serial ATA2 (SATA2)
connectors support SATA data
cables for internal storage
devices. The current SATA2
interface allows up to 3.0 Gb/s
data transfer rate.
These four Serial ATA3 (SATA3)
connectors support SATA data
cables for internal storage
devices. The current SATA3
interface allows up to 6.0 Gb/s
data transfer rate. If the eSATA3
port on the rear I/O has been
connected, the internal
SATA3_A1 will not function.
Either end of the SATA data
cable can be connected to the
SATA / SATA2 / SATA3 hard
disk or the SATA2 / SATA3
connector on this motherboard.
Besides two default USB 2.0
ports on the I/O panel, there are
three USB 2.0 headers on this
motherboard. Each USB 2.0
header can support two USB 2.0
ports.
