Synology RAM Alternative
Exactly the same RAM memory is manufactured by other companies like Crucial and Hyper. Synology warns that if you use any other but Synology RAM, you will void the warranty. But sometimes this is the only option if you need NAS for specific tasks where more RAM is required and you do not want to use Qnap as an alternative. Crucial is one of the most popular alternative brands for Synology RAM upgrades. The specs will look exactly like Synology, which make someone think that all RAM comes from one place just with a different label on the top.
