One thing should be noted before we start on the setup of the drives Is the manual is important on setup. In this case, SilverStone’s manual is not up to par. The SilverStone manual is very sparse. In any event, installation is simple, simply push down on the door lock to open the door panel, insert the SSD drives into the two bay enclosures closing the door behind them.
The next step is connecting the power adapter to an AC power source such as a wall outlet and connects the DC jack to the DS221 device. At this point you are ready to connect the USB cable to the PC and DS221. Here’s where the tricky part begins. At this point you need to start the Storage management service such as Disk Management. This is located on the Control Panel under System management.
Once the drives are detected you should be able to set up the drive(s) in whatever mode you set it to. Where there is an issue is when you want to change modes. To change from RAID 0 to JBOD or RAID 1, you need to switch the back switch to the appropriate mode, hit the reset button, and unplug the DS221. At this point after plugging the power back in the drive should show up as the necessary capacity, initialize the drive, set up a partition and format the drive. Your new RAID 0, 1 or JBOD array is ready to go.To show performance of the unit I tested with two A-DATA S592 32GB SSD drives in RAID 0 modes on both the external SATA, and the USB ports. The drive performance was obviously much greater on the SATA interface as the USB interface doesn’t have the same amount of bandwidth as the USB interface 3.0 Gb/second versus 480Mb/second.
