When it comes to running a business, the question of data storage can be tricky. Requirements usually exceed simply buying some cheap external storage, but most small businesses can’t justify the cost of buying an expensive enterprise-grade server. This is where a good NAS (network attached storage) device comes in handy. Note that we use the phrase ‘good’ NAS device, not cheap NAS device. For this NAS review, we recommend the Synology DS1815+. It’s a great example of a high quality NAS device and with the proper setup and notifications in place, it should suit any small business for years to come.
