Unformatted text preview: Serial ATA or SATA Serial ATA uses a thin 7 pin connector and only uses 250mV of power. SATA drives do not need to have jumpers set for master and slave and has transfer speeds ranging over 300Mps depending on the type of generation you buy. 1 When comparing SATA to IDE the main difference in the type of cable used. The advantage with the SATA is the thin 7 pin cable, it allows for better airflow and the cable can go up to 3 feet. Other big advantages would be the power used to power the SATA drives compared to the 5 volts used by the IDE drives. The transfer speeds have surpassed the IDE interface and with the 3 generation coming out will blow past SCSI. Comparing SCSI to SATA is almost hard to do. When you look at performance SCSI is still top with transfer rates over 640MB/s, but when you throw in price SATA is the cheapest. You can still build a RAID system with SATA and get great performance, you can connect multiple devices using SATA, and SATA still uses less power making it more "Green". Also SCSI still has the bulky cables which plays a role with heat and airflow. making it more "Green"....
