Promise is known in the consumer space for producing entry-level storage card solutions, and it has taken this one level up by producing a NAS. The SmartStor NS4600 is a NAS that takes four 3.5-inch SATA disks. Three sides and the rear are powder-coated silver, while the right-hand side and the front are piano black.
The front is spartan, featuring a swing out lockable door giving access to the drive trays, blue diagnostic lights for hard drive and network activity as well as power, and a one touch backup button. Curiously, the power button is on the back, next to two USB ports, an eSATA port, a single gigabit Ethernet port and an 80mm fan.
The drive caddies are simply four sides of plastic, attached to the drives via four flat screws. It can initially be a little fiddly but it's effective enough, and once the drives are in it has enough structural integrity to do the job.
Flipping to the underside, a hatch is discovered, covering the NS4600's power supply — which is simply an external adapter that's been fitted inside, removable presumably to cut down on heat generation.
Initial set-up is performed through the included SmartNAVI program, which sits in your system tray and allows you to locate and configure your NAS. SmartNAVI could do with a redesign — it looks like an IM client, is non-resizable and gives you no idea of progress after you've selected how you want your disk array to be set up, an infuriating prospect since the unit is inaccessible until it's finished. The unit also beeps annoyingly until SmartNAVI finishes setting up, the device is clearly unable to tell a new set of drives from a failed array.
SmartNAVI also establishes a trend that's continued into the web UI — that is, Promise is trying to use "friendly" terms instead of real world terms, and so users are never really sure what they're getting. For example, initially you are prompted either to set up the disks as maximum capacity or data security. This is either going to set you up as RAID 0 or 5, but it never mentions this, making for some confusing moments. Thankfully, once into the web UI (the awkwardly named WebPASM), you can select RAID 0, 1, 10, 5 or 5 plus spare and it does give volume creation progress here — although you have to go through the rigmarole of deleting the array already established by SmartNAVI.

though, and can't be resized. (Credit: CBS Interactive)
