My next NAS is going to be Ubiquiti UNAS Pro . 7 drive bays for $499. Can’t beat it.
What is the File System? BTRFS or ZFS?
I only wish they do a 2 Bay or 4 Bay version. Or better yet something like Time Capsule. 2 Bay + Ubnt Express.

#32I think they are on their way to exit the consumer market. Their linux kernel is old. And DSM dont update the kernel.

Can you put a custom OS on it, wiping their software? I have a network rack in my basement (so, shallow depth, can’t fit a “full” depth server) and I’m looking for a dumb box of hard drives with otherwise simple/supported-by-linux hardware that I can use to build my own NAS. I don’t really want to use unifi’s software for it (plus it’s nice to just run plex/jellyfin/etc directly on the box)
I currently plug a USB3 4-bay disk enclosure into my homelab server for this, but the cabling is messy and it doesn’t support 20TB drives. I could upgrade to a newer enclosure, but I’d rather have a “real” rack mount system with drive bays.

#34Earlier quoted context omitted.
I think preventing alarm fatigue is a very good reason to fix issues. But 5% free is very low. You may want to use every single byte you feel you paid for, but allocation algorithms really break down when free space gets so low. Remember that there's not just a solid chunk of that 5% sitting around at the end of the space. That's added up over all the holes across the volume. At 20-25% free, you should already be loo…
5% of my 500 GB is 25 GB, which is already a lot of space but understandable. Not many things would fit in there nowadays. But 5% of a 5 TB volume is 250 GB, that's the size of my whole system disk! Probably not so understandable by the lay person.
This is partly why SSDs just lie nowadays and tell you they only have 75-90% of the capacity that is actually built into them. You can't directly access that excess capacity but the drive controller can when it needs to (primarily to extend the life of the drive).
Some filesystems do stake out a reservation but I don't think any claim one as large as 5% (not counting the effect of fixed-size reservations on very small volumes). Maybe they ought to, as a way of managing expectations better.
For people who used computers when the disks were a lot smaller, or who primarily deal in files much much smaller than the volumes they're stored on, the absolute size of a percentage reservation can seem quite large. And, in certain cases, for certain workloads, the absolute size may actually be more important than the relative size.
But most file systems are designed for general use and, across a variety of different workloads, spare capacity and the impact of (not) keeping it open is more about relative than absolute sizes. Besides fragmentation, there's also bookkeeping issues, like adding one more file to a directory cascading into a complete rearrangement of the internal data structures.
Re: Synology Lost the Plot with Hard Drive Locking Move
#35Synology became so bad, they measure disk space in percent, and thresholds cannot be configured to lower than 5%. This may have been okay when volume sizes were in gigabytes, but now with multi-TB drives, 5% is a lot of space. The result of that is NAS in permanent alarm state because less than 5% space is free. And this makes it less likely for the user to notice when an actual alarm happens because they are desensi…

100%. Those disks are likely working much harder moving the head all over the place to find those empty spaces when it writes.

#36I have a 8 bay nas from synology and i’m now considering a move out when i’ll have to replace my nas.
Is there something with 6-8 drives slots on which i could install whatever OS i want ? Ideally with a small form factor. I don’t want to have a giant desktop again for my nas purposes.

#37What's better for running Plex ? Assuming I want 4 drives and something that can transcode multiple files in real time.
About a year ago ago I bit the bullet and frankestiend together a TrueNAS scale box. I hated the idea of the DIY route and stuck with frustrating SOHO nas devices for way too long. An all in one NAS product that has an app store or supports containers is nice in theory but in my experience always ended up with a NUC running proxmox sitting next to the NAS.
Managing it is fine. It expects you to understand ZFS more than a turnkey RAID 5 + btrfs job, but has an OK UI and seems born out of the fact ZFS people want that customization, not forcing you fend for yourself. I read a 15 minute explainer, built a pool, and didn't have to think about it at all other than replacing a failed drive last month. And all that took was a quick google to make sure I was doing it right, which is exactly how I replaced drives in a standalone nas.

Plex runs very happily on my Synology box. So I'd want something that was a reasonably drop-in replacement, and not something that required more work.

#39I wish 1 or more HD manufacturers would get together and sell a NAS that runs TrueNAS on it. Or even an existing NAS manufacturer (UGreen, etc)
All these NAS manufacturers a spending time developing their own OS, when TrueNAS is well established.

TrueNAS isn’t nearly friendly enough for the average user. HexOS may fit that bill, although it seems rather immature. It runs on top of TrueNAS.
