Shuttle, the company responsible for the XPC mini-PCs, also began making NAS devices fairly recently. About a year ago we tested the OmniNAS KD20, and today we take a closer look at the successor, the KD21.
That Shuttle is a true hardware manufacturer is obvious as soon as you pick up the Shuttle OmniNAS KD21. It feels very solid and has a quality finish, you won't find any plastic edges here you sometimes see even on expensive models from other brands. The chassis is made from aluminium and the front has a door hiding two sturdy, metal hard disk trays. At the bottom you have two USB 3.0 ports and a memory card reader. The back has a network port and a USB 2.0 port, for a printer for example. The outside is designed the way you want, in other words.
The dual-core 750 MHz processor used in theKD20 has been replaced by a Marvell 88F6707 processor, one we recently saw in the D-Link DNS-327L. It's not the fast processor in the world of NAS devices, but it's powerful enough for all but the most demanding activities.
