Hi MAM59, Thanks again for the advices. It will be a pure storage as it supposed to ba as NAS. It will be used in a small company and we will store all important data like: documents, GIT repository, tools etc. All server features (GIT, Nextcloud or similar) we need, will be hosted on a separate Hardware in order to keep NAS as storage only. For GIT, only the data will be on the NAS, the DB will be on the same GIT host. DB will be backup regularly on the NAS. I'm not sure we need to move to an array as : all HDDs have the same size, 20 or 30 TB will be enough (GIT doesn't consume lot of memory and documents are not so big). Once NAS storage will be full, it will be time to think about heavier infra as it means company has grown a lot ;-)
