## Questions & Answers

**Q: what is the manufacturer's warranty?**
A: 3 years but do not count on the warranty support, they have been extremely awful supporting any of their products in the past 4+ years.

**Q: Does this come with any cache?  what would be recommended for a single user streaming 1080p video?**
A: It comes with two empty m.2 slots that you can add your own m.2 drives I'm running two m.2 512gb from microcenter. But as far as transcoding from what I've read the ssd cache won't help with transcoding

**Q: I need new sysnology nas as mine is broken  i want plex 4k mine was ds1618+ how does this nas compare to the one i had?**
A: This has a better CPU that 1518+. However, this might not be the best for transposing 4K video as Synology has models that are designed for transposing. I ran plex from another computer and use GPU for transposing so the  1621+ works ok for me.

**Q: Does it come with 2x2gb or 1x4gb for the ram? does dual channel memory make a difference in a nas?**
A: Mine came with 1x4GB. It will run fine with one memory stick (ex: 1x16GB). I eventually upgraded to 32GB using Arch's equivalent memory. If you're using the array just to serve files it's probably fine with 4GB. You might need more RAM if you use the NAS for more demanding tasks. Fortunately the UI provides very good information on memory and CPU usage.
