      What are you seeing from top?

      Maybe try: top -mio -ototal -SH

      That will show you system processes too.

      Not really something I've ever dug into too deeply but iostat looks like it gives more useful data.
      You are certainly seeing higher values that I do:

      [2.4.5-RELEASE][admin@2220.stevew.lan]/root: iostat
             tty             md0             ada0            pass0             cpu
       tin  tout  KB/t tps  MB/s   KB/t tps  MB/s   KB/t tps  MB/s  us ni sy in id
       170     1  0.00   0  0.00  31.28   1  0.03   0.00   0  0.00   0  0  0  0 99

        @andyrh said in is this ok for a SSD setup?:

        Or about 4,000 days at 1.5GB/hour.

        That's not even 11 years! 😉

        PfSense running on Qotom mini PC
        i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
        UniFi AC-Lite access point

        I haven't lost my mind. It's around here...somewhere...

          Mmm, I guess 0.47MB/s is ~1.7GB/h.

          0.03MB/s seems about average on the systems I have here without ramdisks. It's 0 with ramdisks.

          But still well within the expect drive life I would think.

            hello @stephenw10
            thanks all for your feedback. even though, at this rate, the ssd would probably last for a while, im concerned on the higher rate on my system compared to you. its way higher.

            is there anything else i might check on my system?

            here are the outputs:

              I've got to think it's because of zfs. It's not something I've ever looked too hard at because the only place it's really an issue is booting from flash and we don't use zfs there.

                @stephenw10 should i consider UFS for my setup instead?
                i dont have any big power outages concerns since all my systems run on UPS with power generator backup

                  If you can easily test that I would do so.

                  I don't really think you need to worry either way.

                    Does it have a slot for a NIC (NOPE) or are you going to use the wireless, or VLANs on the single NIC?

                      i added an additional mini PCIe ethernet card along with the other NIC that already came with the machine.

                      thanks Steve. i think i can do that tonight and test.
                      after disabling a lot of log options from suricata and pfblockerng, i was able to reduce the write rate:

                        hi again. @stephenw10

                          Yeah, I spoke to our devs about this since I'd never considered it. ZFS is expected to have a higher IO rate than UFS. What you are seeing in either case doesn't seem to be cause for alarm.

                            thanks so much for your feedback and information. i would stick with ufs from now on, due to my basic setup not needing much
