Synology DiskStation DS1621+ is a powerful 6-bay network-attached storage solution designed to store and protect critical data assets. The growing amount of unstructured data requires smarter and increasingly higher performance methods of storing, accessing, and sharing. DS1621+ is a compact desktop form-factor NAS that is beyond evolutionary, featuring over 110K, or 174% higher 4K random read IOPS, compared to its predecessor. Designed for scalability, the DS1621+ enables you to start small, then expand as your data grows. 5-year warranty is available as an optional add-on with the purchase of EW201 at the same time as the NAS.
