Two eSATA PortsProfessional 2-Port 6Gb/s SATA Solution for Mac & PC Notebooks with ExpressCard Slot

Why choose an eSATA Card? If you're planning to connect external storage to your computer, there's a good chance the enclosure will have two or more interfaces from which to choose, including USB, FireWire®, and eSATA. Your computer has USB ports, may have FireWire ports, and maybe even a Thunderbolt™ port, too. So if you can just plug into your computer's existing ports, why consider an eSATA card? Consider the facts that the 6Gb/s eSATA interface offers superior performance to that of FireWire 800, USB 2.0 and USB 3.0 interfaces, and Thunderbolt storage systems carry a price premium over eSATA storage systems. Sonnet's Tempo SATA Pro 6Gb ExpressCard/34 card is cost-effective solution for adding two high-performance eSATA ports to your computer so you can take advantage of this speedy interface.

External storage systems with eSATA interfaces offer great flexibility. Single drive enclosures are very handy if you need to back up data or move files from one computer to another. Many storage systems include swappable drive trays, which are perfect for managing daily backups and multiple projects. Some systems, like Sonnet's Fusion™ QR and Fusion F3, feature hardware RAID controllers that manage up to four drives and enable you to create large, protected RAID volumes, yet the systems only require a single cable to connect to this pro eSATA card.

Improved Performance

SpeedometerTempo SATA Pro 6Gb ExpressCard/34 is versatile. Its fast, 6Gb/s eSATA interface is well suited to deal with the increased bandwidth requirements of 6Gb/s SSDs. Built around a second generation 6Gb chipset, it offers greatly improved performance over older 6Gb/s eSATA cards and is capable of transferring files at up to 375 MB/s! More onboard cache enables this Sonnet controller to perform even better in the latest computers, and Sonnet's Echo™ ExpressCard Pro Thunderbolt Adapter
