Building your own Network-attached storage (NAS) can be a costly endeavor. You can still make it a little less draining on your available budget by picking up discounted Synology NAS models and compatible hard drives as part of Amazon Prime Day. The budget-friendly DS220j is available for $136 (was $170), while the expansive four-bay DS920+ is listed for $440 (was $550).

Before you plan ahead, it's worth considering that you'll need to have an active Amazon Prime membership to gain access to these promotions. The good news is you can sign up right now for a free 30-day trial to start prepping for a home media server.

Synology DS920+

Synology's DS920+ is an excellent NAS for those who only require four drives installed for storage. Whether you want to store important files or create your own media server, this is a great starting point.

Your Synology NAS will be useless without hard drives, and Western Digital Red 4TB drives are listed for $90, down from $120. That's a massive discount that makes the drive well worth considering, but you'll need to purchase at least two of them to set up a RAID for better data redundancy.

Synology's DSM even supports surveillance cameras, which you can also find currently on sale for Amazon Prime Day. You will need to double-check with Synology that the camera you plan on purchasing will be compatible with the DSM OS of the Synology NAS, as well as the surveillance software. Be sure to check out other NAS-related deals on Amazon and sign up for a 30-day free trial of Amazon Prime if you haven't already done so to take advantage of these great deals.
