Have been using TR-004 for 10 months+. Made in TW, 2Y warranty and it's very stable (running at 24/7). This model supports USB 3.2 Gen 1 only. We need to go for TR-002 (2-bay) if USB 3.2 Gen 2 (10Gbps) is required.
FYI, while Century DAS is supposed to be durable, there was exception. I had a 4-bay Century DAS died in 13 months of use ... only got 1Y warranty (as we know) !!
