eSATA means External Serial Advanced Technology Attachment (SATA) and it is a storage drive that covers optical drives and HDDs. The configured eSATA interface of an eSATA external hard drive, in contrast to the USB interface, offers an unpowered signal connection for external storage devices.

As a popular external hard drive, eSATA is showcasing its pros and cons along with its working process. Follow this content below to have a good understanding of its pros and cons.

The strengths of the eSATA external hard drive:

  • eSATA external hard drive outstands itself for the speed of data transfer. It breaks the speed transfer rate limitations by skipping the USB data channel and applying the channel used by the internal hard drives of computers. According to techpreview, its data transfer speeds can reach up to 600MB/s(6GBps).
  • By applying a specific eSATA case, a regular SATA drive can be transformed into a portable eSATA drive. The higher transfer speed is at hand then.
  • Flash memory can also take advantage of the pro of eSATA if there is one eSATA port on your device. You can enjoy the higher performance of the eSATA port and the standard speed of a conventional USB port.

  • eSATA cable maxes out at 2 meters compared to USB's 5 meters, which is a little bit inconvenient for you to use.
  • eSATA is younger than a normal USB drive so it is not available on many computers. It only supports Windows 2000 Pro or later operating system or Macintosh System Mac OS X (or higher).
