Along with the TeraStation Pro II, Buffalo Technology announced its new DriveStation Quattro USB 2.0/eSATA external hard drive at CES 2007. Combining four 7,200rpm drives in 1TB and 2TB configurations, it is capable of data transfer rates of up to 100MB per second, according to Buffalo. The drives can be arranged in RAID 0, RAID 1, and RAID 5 arrays for improved performance and data security. Buffalo also bundles Memeo AutoBackup for Windows. Unlike the TeraStation Pro II, the four drives aren't swappable.
When connecting the Quattro to your Windows or Mac PC, you can use either a USB 2.0 connector or eSATA, which allows you to connect an external drive directly to your system bus.
Both capacities will be available in late January and will cost $600 for the 1TB and $1,000 for the 2TB.
