A small example .:
I bought an external combo enclosure for 2.5 inch SATA hard drives from IcyBox (RaidSonic). The housing has USB2.0 and eSATA as selectable connections, actually very practical for mobile use. But unfortunately, like my Asus notebook with eSATA interface, the mentioned case does not supply electricity, there is an additional power supply or an appropriate USB power cable is required, the course occupies one of the ever-scarce USB ports.
The misconception .:
I have long mistakenly believed that can provide my notebook via eSATA (... is a so-called USB-eSATA combo port) No external devices with power. But this practical DELOCK eSATAp cable supplied any storage devices, whether solid state or hard disk, on my Asus laptop with the necessary operating current. The only limitation are probably all storage devices beyond 2.5 inches, as they require more energy and are just eh not really to handle mobile, so I have not been able to verify (... do not own 3.5Zoll disks more). Possibly can be personalized with the cable DELOCK even SATA Notebook Slim drives such as CD & DVD or BD operate externally without power supply, this but I have not been able to check also.
Conclusion .:
A truly practical and above all functional eSATA power cable that should be in every range an advanced computer user, it is ideal for testing and preparation purposes, as well as for fast data backup. The round cable (... my) is about 57cm long and is sufficiently flexible, it has an eSATA port and a conventional SATA connection, moreover, it is meticulously crafted.
