What bothers me, especially because there is no abundant info or photos (which would make)
is the absurd power adapter - not only that the power supply in many power strips two sockets
occupied (square terms) but also an intermediate adapter between the power supply and hard drive connection.
Why not an "old" Molex connector is used with an adapter cable to "new" SATA power there,
reveals itself to me is not really - more expensive, a Kästelchen more and two adapter cable with a connector,
which is suitable not for frequent changes.
The beige supplied adapter cable for power supply to the HDDs and the SATA cable is plugged in which side
(For HDD) are very short - about 6 cm.
