You’ll Feel SATAsfied Inside!
Do your storage needs outweigh what your new dual-core Power
Mac® G5 can support? Stuff it—with drives, that is! Sonnet’s
Tempo SATA E4i 4-port Serial ATA Host Controller for PCI Express
enables you to connect up to 4 additional internal drives for the
perfect balance of flexible expandability and superior performance.
This card is an ideal companion to our G5 Jive internal drive
mount system for Power Mac G5 computers—along with your SATA
drives, this combination is the most cost effective way for adding
up to 3 Terabytes of high-performance capacity to your G5.
Do you need more speed? Tempo SATA E4i offers 3Gb/s per port
data transfer support and gives you performance to burn! You’ll
get great performance from individual drives, but grouping up to
four Serial ATA hard drives in a RAID 0 (striped) set will provide
astonishing sustained read/write performance numbers enough to
capture and process High Definition video! Want more security?
Set up your drives in a RAID 0 (mirrored) or RAID 10 (striped/
mirrored) set for up to 1.5 Terabyte of data redundancy. When you
need more flexibility and performance than offered by standard
solutions, get a Tempo SATA E4i—it’ll give you room to grow and
blazing performance for the most demanding applications.

Important Notes: 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. For
more information, see the Product Page (http://www.sonnettech.com/product/tempo_sata_e4i.html)
*Parallel disk drives are supported when using Sonnet Tempo Bridge or similar parallel-to-Serial ATA drive adapter.
