In the realm of hard drive interfaces SATA is king, but not all computers are built to accept it. This is why Sonnet Technologies has created the Tempo SATA E4i Serial ATA Host Adapter which allows up to four individual internal SATA drives or four RAID (0 or 10) grouped drives at SATA II speeds of up to 3 Gbs.
Key Features
3 Gb/s per port SATA II controller
Native PCI Express (PCIe) x4 host bus interface for high-performance applications
Spread Spectrum Clocking (SSC) support for compatibility with all SATA drives and lower EMI emissions
