The G-Tech G-SPEED eS PRO is a professional external hard drive array aimed at the multi-track video recording/post-production studio. The enclosure houses four hot-swappable SATA II drives which come prearranged in RAID 0 (speed) formation. This means that all drives are recognized by the computer as one drive, and data transfer speeds remain fast. An online server is also available which automatically checks the drive for problems, even sending up to four emails if there are any serious issues. This and the G-SPEED eS are a popular choice amongst professional and home users who work in large scale video production, the difference being that this is much faster with it's 12Gbit mini-SAS connection. Unfortunately it can only be linked with one other eS PRO for a total of 16TB available drive space whereas the regular G-SPEED eS uses the slower 3Gbit eSATA but can be chained together in groups of four for a maximum of 32TB. As usual G-Tech drives look like and are formatted for use with Macintosh OS X computers, Windows XP and Vista users will require a reformat before using.
