The Tempo SATA Express 34 controller is compatible with 15- and 17-inch MacBook Pro laptops and with any Windows laptop with an ExpressCard (54) or ExpressCard 34 slot. Performance with the Tempo unit surpasses that of disk arrays attached by USB 2.0, FireWire, or even FireWire 800. With two external SATA drives attached in a RAID 0 array, the Tempo SATA Express 34 can achieve sustained disk write and read speeds of 100 and 110 MB/sec, respectively, which is about three times as fast as USB 2.0 or FireWire connections to the same drive setup.

The product is priced at $129.95; supports Windows XP and Mac OS X RAID 0, 1, and 10; and features Spread Spectrum Clocking (SSC) support for compatibility with all SATA drives.
