News: MicroNet's new eSATA box overcomes volume limit
MicroNet has launched a 5TB external serial ATA (SATA) desktop drive array which overcomes a 2TB ATA volume limit. It transfers data twice as fast as USB or FireWire-connected products and comes with built-in RAID protection and needs no operating system drivers. The Platinum RAID Pro can have up to 5 SATA drives and utilises the external SATA (eSATA) connection method which has a data cable up to 2m long and a separate power cable for the desktop enclosure. The eSATA connection method was defined because high-capacity SATA drives, capable of transferring data at 150MB/sec in first generation SATA, can swamp USB 2.0 and FireWire 400 ports. These transfer data at burst rates of 33.5 and 36.2MB/sec respectively, thus bottlenecking drive I/O. The eSATA burst rate is 111.3MB/sec.
