If you have a Power Mac G5 equipped with PCI Express (PCIe) expansion ports and you’re looking for fast external storage, be aware that MaxUpgrades now has available the MaxExpress 2-port eSATA host adapter. It costs $49.
The card can support sustained data rates up to 65 megabytes (MB) per second per channel, according to MaxUpgrades — well suited to users who need high data transfer speeds for digital video, for example. The card supports RAID Level 0 and Level 1 configurations.
MaxUpgrades also offers an internal two-port version.
Earlier Power Mac G5s did not feature PCI Express — they had PCI-X expansion slots. Please make sure your Mac is properly equipped before ordering this card.
