Question about Samsung 870 QVO

Yes, flawless. I use two of them in a DS918+.

Hello,
Thank you for your enquiry.
The SSD 870 QVO is more suitable for a NAS that is mainly read from with little write access.
However, due to the higher TBW values, we rather recommend an 870 EVO for moderate write access or an 860 PRO for frequent write access.
Kind regards from Schwalbach,
Your Samsung Service Team

I have been using 4x8TB for 5 years and never had a problem.
