SATA Connectors : SATA1 and SATA2
The EITX-3000 board supports two Serial ATA ports via two
onboard connectors (SATA1 and SATA2). Data transfer rates up to
300MB/s are possible, enabling fast data file transfer with
independent DMA operation. .
In connecting the SATA power via onboard S-Power 1 and S-
Power 2 connectors, SATA1 and SATA2 can only support 2.5-inch
Hard Disk Drives, and won’t be able to support 3.5-inch Hard Disk
Drive because 3.5-inch Hard Disk Drive requires a 12V power
source.
