when you use QTier with only 1 SSD, what Raid level do you use for the Tier level? The other level (with 3 HDs) is Raid 5? Is SSD data protected?

No just 3 hdd = raid5 So the SSD just use to save important data. The correct way is use 4 HDD with 1 or 2 m.2 SSD. To do the best value.

@@3cdogs thanks for the response. I read on QNAP support and the manual said at least 2 SSDs are required to be in Raid 1 while rest of HDs are in raid 5 for QTier to work as SSDs Tier need to be protected. I'm getting 453D next week and want to use QTier based on your video but it does not seem possible since highest Qtier level should also be on raid 1. So i'm very confused. I want to follow your setup with 3 8TB HDs and 1 500GB SSD.

@@3cdogs at 3:23 of your video, i see that you have two raid groups- you only show raid group 2. can you show what is Raid Group1? that would clarify things. thanks

@@tc41 the data is all clean now. Group 1 is just 512GB SSD. That's right.
My opinion is based on my couple of years experience on QNAP. Don't buy it. Buy something more stable. QNAP software is crap and will give you outages and outages over and over again. For example recent firmware update done by system and after firmware update, can't login. Means can't access anything because of encrypted storage. QNAP responded after 2 days and their instructions didn't fix the issue still. No response for last 24 hours and I'm still waiting after 4 days of complete outage. Hoping that eventually at least it gets fixed without any data loss. It has been a disaster situation so far. Time I have spent on QNAP issues working with them again and again every now and then is really just too much too handle when I have already too much work going on.
