Sarotech has introduced two new NAS (network attached storage) devices over in Korea, namely the C2-US and the C4-S. Both introduce a new and more efficient cooling chassis, and the improved airflow should certainly go some way to help prolong the life of your overworked hard drives. The C2-US supports 2 SATA drives in RAID 0/1/JBOD configuration, while the C4-S supports RAID 0/1/3/5/10/Clone, along with both hardware and software RAID solutions. The C2-US is going for $103, while the C4-S will set you back $287. Too bad there isn’t any mention of when (if ever) these devices will be making it over to our side of the pond.
