Synology DiskStation DS418j NAS Review

Article Index: >>    


Synology DiskStation DS418jLast year we had an opportunity to review Synology’s DiskStation DS416j, a Network Attached Storage device. We liked every aspect of this device and based on the benchmarks and in depth discoveries gave a highest rating we could. This year Synology is releasing a newer model of ‘J’ series, DS418j. DS418j is a physical replica of DS416j however, internal components has been improved drastically to improve performance and features. Our friends at Synology has provided us with a DS418j for evaluation.

Review Sample Provided by: Synology
Product Name: DS418j

Product was given in exchange for work done to produce this review.

Packaging

Packaging of DS418j is recycle friendly. The shipping box is plain with just a sign of DiskStation on the front. Internal packaging consists of plastic foam that holds everything together and a plastic bag that keeps DS418j unit free from accidental scratches and dust.

Just like DS416j, Synology included all that you are going to need to get up and running in no time. What is helpful with all of the Synology NAS products is the Quick Installation Guide which is included. In the image above you can see few bags of screws (for HDD and SSD), power brick, power cord and Ethernet cable. Supported drives that could be used in DS418j are 3.5″ SATA HDD, 2.5″ SATA HDD and 2.5″ SATA SSD.
