Sonnet has announced a faster, 1TB version of its Fusion F2 portable two-drive RAID SATA storage system. The new version uses 7,200rpm drives, which Sonnet says offers 20 per cent faster performance than the original Fusion F2 1TB model with up to 190 MB/sec read and write sustained data transfer rates

Read our review of the original Fusion F2.

The Fusion F2 can be bus-powered to enable usage when grid power is unavailable. The diminutive system consists of two 2.5-inch, 500MB drives mounted side by side in a rugged aluminum enclosure, features two eSATA data ports, and is designed for use with the Sonnet Tempo SATA Pro ExpressCard/34 controller for the MacBook Pro and Windows notebooks.

The Fusion F2 aims to be an alternative to existing FireWire and USB portable drive solutions. The F2 transfers data via two eSATA ports, but may draw power from a powered FireWire port for a truly portable operation. The drive supports portable video capture in conjunction with an AJA's Io HD, which requires dedicated use of FireWire bandwidth.

To protect field footage, Fusion F2’s drives can be configured in RAID 1 mirrored mode, and still can capture Apple ProRes HQ HD fed from an AJA ioHD. This protected mode also allows safe field transfer of Panasonic P2, Sony SxS Pro, or similar memory cards.

Each Fusion F2 drive is individually shock-isolated, protecting the drives during transport.

The 7,200rpm Fusion F2 1TB costs £390 plus VAT from AM Micro.
