Edge10 2.5TB DAS501t

DAS501t, 2.5TB, SATA, 8.89 cm (3.5 ") , eSATA DAS501t enhances your data storage by combining advanced RAID features typically seen on high-end data systems with low cost/ high capacity Serial ATA drives. By using industry standard SATA drives and Silicon Image Host Bus Adapters, you can achieve extraordinarily low costs while remaining assured that your data is protected against hardware failure.
The DAS501t software driver also supports Contiguous and Concatenated drives for applications which do not require increased security or performance.
The DAS501t utility offers an easy to use utility for creating and managing your storage. It also supports the latest SATA enhancements including SATA-II Port Multiplier support, and up to 3Gbit/sec transfer rates on controllers that support that speed. Creating and deleting volumes is also possible without requiring a restart of the operating system and rebuilds never require the data to be taken off-line.
Drives can also be moved between controllers without losing the data.
