Samsung Electronics GmbH
Hello,
Thank you for your enquiry.
The Samsung SSD 870 QVO SATA III 2.5 inch is best suited for a NAS that is mainly read and only has little write access. For more frequent write access, we recommend the Samsung 870 EVO due to its higher TBW values and for very frequent write access the Samsung 860 PRO.
Kind regards from Schwalbach
