A company called FirmTek has announced that it is now shipping a new four-port eSATA host adapter that is compatible with the latest Apple Snow Leopard OS. The device works with both 32-bit and 64-bit modes in the OS and the device is backwards compatible with older versions of Mac OS X.
The adapter is aimed at Mac pro users who want to add storage capability to their machines with support for RAID 0 with performance as high as 540MB/sec. The device promises up to 250MB/sec of performance per channel. The host adapter can be added into a 5-bay SeriTek/5PM port-multiplication enclosure to allow up to 20 drives to be connected.
The host adapter is compatible with all Mac Pro models and the PowerMac G5 from late 2005. The device requires a PCI-Express slot with 4x bandwidth. Supported drives include SATA I 1.5Gb/sec and SATA II 3Gb/sec. The host adapter is available now for $199.95.
