One of the best deals in today’s Amazon Prime Day event is a significant discount on the Synology DiskStation DS920+ 4-Bay NAS Enclosure — it’s discounted $110 to only $439.99. This model was just released a few months back and it’s a very popular entry in Synology’s line-up. A 20% discount this early after launch is very rare — don’t miss out on this deal (B&H is already backordered).
