Tempo SATA Pro 6Gb
4 Port 6Gb/s eSATA PCIe Host Adapter

Mac | PC | PCIe | eSATA

Tempo SATA Pro 6Gb 4-port is versatile. Its fast, 6 Gb/s eSATA interface is well suited to deal with the increased bandwidth requirements of 6 Gb/s SSDs.

Built around a new, second generation chipset, it offers greatly improved performance over older 6 Gb/s eSATA cards.

More onboard cache enables this Sonnet controller to perform even better in the latest computers and Sonnet's Echo Express Thunderbolt Expansion Chassis for PCIe Cards.

Why the Sonnet Tempo SATA Pro 6Gb?
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 FireWire®, USB, 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 6 Gb/s eSATA interface offers superior performance to that of FireWire 800 and all USB interfaces, and Thunderbolt storage systems carry a price premium over eSATA storage systems.

Sonnet's Tempo SATA Pro 6Gb 4-port card is cost-effective solution for adding four high-performance eSATA ports to your computer so you can take advantage of this speedy interface4.

  1. Support for 20 drives requires the use of drive enclosures employing port multipliers (like Sonnet's Fusion D500P, Fusion D400QR5 or R400QR5). When using an enclosure without a port multiplier, Tempo SATA Pro ExpressCard/34 will support 2 drives.
  2. Western Digital manufactures Desktop edition (WD Caviar, Caviar SE, Caviar SE16, and Raptor X) hard drives and Enterprise (RAID) Edition (WD RE, RE2, and Raptor) hard drives. Each type of hard drive is designed to work specifically in either a desktop computer environment, or connected to a RAID controller (hardware or software-based). If you intend to configure Western Digital drives in a RAID set, Sonnet and WD recommend using only their Enterprise edition hard drives.
  3. Sonnet Tempo cards are compatible with most external SATA storage. However, external hard drives with USB 2.0/eSATA dual interface based on the Oxford Semiconductor OXU931DS storage controller chip may not be compatible with Mac OS X when connected via SATA. Known issues are kernel panics occurring when the drive is connected, or the drive not being recognized by the operating system.

Rating: 5/5 Boots OS X 10.6.8+ @ SATA III / 6Gb/s on Mac Pro 3,1 thru 5,1! January 31, 2019 CAVEAT! : You MUST download the Sonnet Tempo™ Firmware Updater “MarvellFlasherGUI.dmg” from their Sonnet’s Support Library… Be SURE to FOLLOW their instructions PRECISELY!… If you just plug ‘n’ play… you will ONLY be able to READ / WRITE @ SATA II 3 Gb/s speeds… External drives will MOUNT… and show up in the System Preference Pane / Startup Disks… but… NOT BE ABLE TO BOOT!… They will DEFINITELY NOT show up during OPTION-START!… ONCE you UPDATE this card’s FIRMWARE… it will READ / WRITE… and BOOT… like “greased lightning”!… Also, be certain to install this card in one of the 4, or 16-lane PCI Express 2.0 slots. The 1.1 slots on the Early 2008 MacPro 3,1 models do not have the bandwidth for SATA III 6Gb/s; they will limit speeds to SATA II 3Gb/s… ENJOY! = : ^ D ><>
