Sonnet Tempo SATA E4P - 4 Port PCI-Express eSATA Card with Port Multiplier

This is a PCI-Express card, which is the expansion card used in Apple Workstations from the PowerMac G5 Dual-Core onwards. These cards are only compatible with PCI-Express enabled computers, and will not work in older PCI or PCI-X based systems.

Able to control up to 20 drives, the Tempo SATA E4P delivers performance previously unattainable with mainstream technologies. For the utmost performance, you can create multiple RAID arrays to capture and process uncompressed high definition video, or conquer other high-bandwidth applications.

You also have the flexibility to work with 20 drives individually and hot-swap them out as needed. You can even work with a combination of RAID arrays and individual drives.

If your storage needs have outgrown standard solutions, get a Tempo SATA E4P - it'll give you room to grow and blazing performance for the most demanding applications

The perfect enclosure to work with the Tempo E4P is the Sonnet Fusion D500P, a 5 bay drive enclosure with support for port multipliers. Each controller on the E4P can control an entire Fusion 500P array!

This PCI-Express Card is only suitable for PowerMac G5 Dual Core machines and later, for earlier machines, see the Sonnet Tempo SATA X4P.

Please note the following warning from Sonnet: While some customers have successfully used external hard drives with dual USB 2.0/eSATA interfaces, these products (based on the Oxford Semiconductor OXU931DS storage controller chip) exhibit underlying errors that prevent them from being fully compatible with this Sonnet product under Mac OS X. Kernel panics occurring when the drive is connected, and the drive not being recognized by the operating system are known issues. These drives include, but are not limited to:

Sonnet's Fusion D400Q and R400Q quad-interface storage systems are not affected by these issues, and are fully supported.
