Symwave SOC USB 3.0 chip will enable RAID performance

Symwave, one of the first companies to design silicon for USB 3.0 (to provide throughput as high as 5Gbyte/s, up from just 480Mbit/s for USB 2.0) has revealed more details about the performance of its system on a chip (SOC) that can be used in external storage devices that ship data as fast as 500Mbyte/s second.

Symwave, one of the first companies to design silicon for USB 3.0 (to provide throughput as high as 5Gbyte/s, up from just 480Mbit/s for USB 2.0) has revealed more details about the performance of its system on a chip (SOC) that can be used in external storage devices that ship data as fast as 500Mbyte/s second. The SATA I/O protocol used with most hard drives can transport about 300Mbyt/s second, while USB 2.0 typically delivers just 20Mbyte/s or 30Mbyte/s, he said. "USB 2 was good as long as you had 100GB on your hard drive, but now it's just way too slow." The chip’ll allow OEMs of storage devices and enclosures to offer speeds as high as 500Myte/s because it includes support for RAID 0 configurations. Using RAID, the system maker can build an enclosure with two drives and either feed data faster by addressing both drives at once, or feed the same data to both drives so one is a mirror of the other, Intrater said.
