Dual controller NAS

Last updated on 08 Apr 2021 📧 Subscribe

I am looking for a dual controller NAS.
Like Synology UC3200, 10GB Ethernet.
Only with SATA SSD disks.
Purchased 6x 2TB server SSD, few months ago and like to reuse these if Possible.

Could you please tell if there is a possibility for a suitable Dual controller NAS using SATA ( Like Synology UC300 ?).

If not possible what could be the alternative using SAS disks, or is the Synology UC3200 best option using SAS disks 10GB Ethernet).

It would be recommended to use SAS drives in this enclosure. Otherwise, you would miss out on potential speed benefits. SATA is 6Gbit and SAS is 12Gbit connection.

Normally SATA drives supposed to work on an SAS connection. You can also try to use SAS adapter with your SATA SSDs https://www.qnap.com/en-uk/product/qda-sa2

I hope this helps.
