Synology DiskStation DS1515+ Network Attached Storage Review
What is a NAS? NAS Stands for Network Attached Storage, and it is a device that resides on your network and can have multiple drives in a RAID array. The drives contain folders that can be accessed by all or a few computers on your network depending on the permissions set. Having a NAS on your network offers a few benefits such as increase in storage capacity, data encryption, and depending on the RAID Array, limited protection of data stored on the device. Most units offer features that go beyond just a storage device; a lot of the desktop NAS offer features such as a media library, media streaming, iTunes Server, and cloud based backups. Synology’s DS1515+ is a 5-bay NAS that features an Intel Quad Core CPU, 2GB of DDR3 RAM and four gigabit Ethernet ports.
Packaging
Typically, a NAS is marketed towards the Small Office/Home Office (SOHO) or small business crowds so, flashy packaging isn’t necessary. The same goes for the Synology DS1515+ as the packaging is plain cardboard with black text and line art graphics with a couple of informational stickers attached.
Internally, the NAS is packed away in a pair of rigid foam inserts and covered with a soft anti-scratch bag.
The Synology DS1515+ comes with a 6′ power cord, two 6′ Ethernet cables, hard drive screws, a set of keys, and a quick start guide.
