External SATA

Was standardized in mid 2004, with specific definitions of cables, connectors and signal requirements for external eSATA drives. eSATA is characterized by:

• Speed SATA disks in external (to be measured 115 MB / s with RAID external).
• No conversion protocols PATA / SATA to USB / Firewire, all disk features are available for the host.
• The cable length is restricted to 2 meters, USB and Firewire allow greater distances.
• Increased the transmission voltage to minimum and maximum 500mV - 600mV (400 mV - 600 mV).
• Voltage received decreased to 240 mV - 600 mV (325 mV - 600 mV).
• Ability to layout of disks in RAID 0 and RAID.
