Replacing old Seagate BlackArmor 4-bay NAS - what's the current recommendation?
So I previously got a free Seagate BlackArmor 4-bay NAS that was being retired but still worked. I replaced the drives with four 16GB units and it has performed decently, but I recently noticed that it is using an allocation unit size of *4GB*, which is killing my capacity. I've never seen that before - I'm used to single drives with allocation sizes measured in kilobytes. Is that normal for NAS in general, or just this particular model?
i.e. The amount of space consumed by any file is rounded up to the nearest multiple of 4GB. Even a text file that is less than a megabyte of actual data consumes 4 gigabytes on the NAS volume. As far as I can see, this is not configurable in the ancient (but latest) firmware for this deprecated device.
So I'm in the market for a new 4bay NAS that I can use these same 16GB SATA drives in instead. The Synology DS425+ and DS925+ both look good and I've heard good things about Synology, but they are a bit pricey. I've also started looking into building my own storage server, but that's a rabbit hole that will take some time to delve.
So I'm hoping some experienced people here can comment. What would you recommend in my situation?
Also can anyone confirm that allocation unit sizes on their NAS volumes for me? I could use a good reality check.
