Sonnet ships eSATA adapter for ExpressCard

MacBook Pro owners have relatively limited options for high-speed external hard drives, especially if they need to connect to multi-drive storage units. Sonnet's now shipping Tempo SATA Express 34 gives them, and any other users of laptops with ExpressCard slots, two 3Gbps external SATA (eSATA) ports that can be used to connect hard drives that use the high-speed interface. When two drives are connected in a RAID 0 stripe the sustained transfer rate is better than any USB 2 or FireWire setup -- it can write at 100MB per second, according to Sonnet. The new Tempo card can additionally support up to 10 drives if each port is connected to an external enclosure with a built-in port multiplier. Mac and Windows users alike can purchase the Tempo SATA Express 34 now for $130.
