Just use a plain simple cheap SATA cable) More complex (No need to use that Apricorn wire.I cable from the desktops PSU to which you are connecting the drive will work, but has the following disadvantages over just connecting the drive via SATA: This can be done both via en external power supply or via another source. If you still want to use a regular desktop drive via USB then you will need to supply it with power from an other source than the USB bus. Some drives use more and use an ugly hack with two USB cables to try to draw more power. Most USB powered drives in an external casing are 5400 RPM drives drawing just shy of the max power supplied by the USB 1/USB2 bus. Laptop drives usually use only +5 volt and draw less power. Even if you convert some of the supplied +5 volt line to +12 volts. USB can not provide enough power for these. Both however are fed with +5 volt and +12 volt. a 15K RPM SAS drive is likely to use a lot more power then a 5400RPM drive. Packaged with our user-friendly Cloning Software and using an ultra-fast USB 3.0. Depending on how much more power can be delivered this might be granted or not.įor USB 1 and USB 2 this is maximum 500mA at 5 volt (max 5 Watt).įor USB 3 this can be up to 900mA at 5 volt.Ī typical 3½ desktop drive uses up to 15 Watt at start up, and about 5 to 10 Watt when mostly idle.
