Welcome to QNAP - network attached storage ( NAS ) and surveillance products provider. We wouldn't go so far as to recommend the TS-509 to small business users with relatively little technical knowledge, as its price and sheer range of features mean that it remains very much a product for corporate users. However, it is easier to set up and maintain than many similar RAID devices, making it a good option for larger organisations that are looking for a high-capacity, low-maintenance storage solution... - Chirag Batra
