At "Embedded Systems 2009" in San Jose Pretec unveiled the first peripheral to implement Power Over eSATA technology. Until now, eSATA peripherals have needed an external power supply via an adaptor for hard drives or via the the USB port. In contrast to the USB 2.0 or Firewire 400/800 ports, the eSATA port cannot supply power. In January 2008, the SATA-IO announced the development of Power Over eSATA for the end of the year but we hadn’t heard anything more since.
So this is good news from Pretec, even if the eSATA ports on motherboards do not yet support this standard. This is no doubt an attempt by SATA-IO to preempt forthcoming Firewire 3200s and USB 3.0 which have theoretical speeds of 400 and 600 MB /s respectively, at the same time as supplying power. Pretec’s peripheral is an SSD called Cobra eSATA/USB SSD. It is both USB 2.0 and eSATA and will be available in 32 and 64 GB versions at an as yet unknown cost. It has a theoretical speed of 90 MB/s in read and 60 MB/s in write.
