Seagates External SATA Drives: Speed Meets Capacity
Review: Seagate's eSATA Pushbutton Backup Hard Drive moves data up to five times faster than USB 2.0 or Firewire external hard drives.Moving data between your computer and an external drive takes time. With bigger data volumes, major backups or real-time video editing often take too much time. The biggest speed bottleneck is likely to be the physical interface to the disk, as anyone whos tried using USB 1.0/1.1, and then gone to USB 2 ("Hi-Speed") or to FireWire.(IEEE 1394), knows. SATA (Serial Advanced Technology Architecture), which can do data rates up to 3G bps, is rapidly supplanting the older ATA (aka Parallel ATA, PATA), which has been around since the 1980s, for internal drives in desktops, notebooks, NAS devices and smaller or low-cost serversand now, also in external hard drives.
