Tempo-X eSATA 8
Sonnet has announced ($300), the first Serial ATA (SATA) host controller with eight external ports for Power Mac computers. This high-performance adapter utilizes the PCI-X interface to take advantage of the enhanced performance offered by Power Mac G5 computers while retaining compatibility in standard PCI slots. Each port is independently capable of data transfer rates of up to 150MB/s. While attached drives can be formatted for individual use, "the benefit of using Mac OS X Disk Utility to group them in RAID 0 (Stripe) arrays is clear" -- 8-drive arrays can sustain read/write speeds in excess of 545MB/s, useful for capturing and processing uncompressed 10-bit High Definition video without dropping frames. This card's eight external ports make it easier than ever for users to add storage capacity simply by plugging in cables between their computer and SATA drive enclosures.
