We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Does a 3 x 4TB SSD RAIDZ1 makes sense? (alien.top)

I'm building a new little NAS. I've got no big requirements in terms of space (8 TB would be fine, the more the better of course) and I've got doubts deciding which way to go. I already have a 4TB Crucial MX500 SATA SSD and the idea was to spend another €400 in drives. After investigating I've got two main options:

  1. Buy another two 4TB SSD (€380) units to have three and configure that RAIDz1
  2. Buy three HGST HUH721010ALE601 10TB (€390), configure them in RAIDz1 and have more storage

Does that first option make sense, or I should just go with traditional disks? The purpose of the build is to run TrueNAS/Unraid (I'd maybe give Proxmox a go) to manage photos (with Photoprism, Photostructure, or some other alternative, I plan to test a few) and run several containers with Jellyfin etc, maybe some virtual machines to play with ocassionally.

I've got a 4-disk RAID-Z1 and read speeds will come pretty close to saturating my gigabit Ethernet. My write speeds are a pretty consistent 60MB/s over the network. I'd really only go with SSDs if the NAS was an intermediary box that absolutely needed fast write speeds but then itself persisted to a larger but slower HDD box.

In general though I'm after storage primarily and speed second.

Great. Thanks!
