You'll Feel SATAsfied Inside

Do your storage capacity needs outweigh what your computer can support on its own? Stuff it—with Serial ATA drives, that is! Sonnet's high-performance Tempo™ SATA E4i 4-port Serial ATA host controller for PCI Express slots enables you to connect up to 4 additional internal SATA hard drives(1) for the perfect balance of easy expandability and superior performance. If you own a Power Mac G5, this card is an ideal companion to Sonnet’s G5 Jive™ internal drive mounting hardware for Power Mac G5 computers—along with your SATA drives, this combination is the most cost effective way for adding up to 12 Terabytes of high-performance storage 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(2) will provide astonishing sustained read/write performance numbers, enough to capture and process multiple streams of HD video. Need more data security? Set up your drives in a RAID 1 (mirrored) or RAID 10 (striped/mirrored) set for up to 6 Terabytes 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.
