22 July, 2014: The Promise J4 is about the size of a Mac Mini, and you have to undo five screws on the bottom and lift up the top part of its chassis to get to its internal drive bays. Here, in order to install or remove drives, you need to use the screwdriver again, since each drive is secured to the chassis by another screw. Taking off the top is quite easy, and installing all four drives takes just a few minutes, but still, this is a backward design. The only good thing is that you can’t accidentally remove a drive, which might lead to data loss. Promise says it’s contemplating a better design for the next version of the J4.
With an aluminum and plastic body, the J4 looks good. There’s an array of small LED lights on the front that shows the device’s status. On the back are two Thunderbolt ports, the power connector, and a power button. You need to press and hold this button for a few seconds to turn the drive off. Most of the time, turning it off is unnecessary since the device’s power status is linked to that of the Mac it’s connected to: it goes to sleep when the computer is in sleep mode and wakes up when the computer is awakened and so on.
