      thanks Steve. this sounds concerning

      regarding the issue you mentioned, this is a very recent install (about 1 week).

      here are my mount points

      # mount -p
      zroot/ROOT/default      /                       zfs     rw,noatime,nfsv4acls    0 0
      devfs                   /dev                    devfs   rw              0 0
      zroot/var               /var                    zfs     rw,noatime,nfsv4acls    0 0
      zroot                   /zroot                  zfs     rw,noatime,nfsv4acls    0 0
      zroot/tmp               /tmp                    zfs     rw,nosuid,noatime,nfsv4acls     0 0
      /dev/md0                /var/run                ufs     rw              2 2
      devfs                   /var/dhcpd/dev          devfs   rw              0 0
      #
      

      and my /etc/fstab file which interestingly doesnt show any other partition (i dont know why)

      # Device                Mountpoint      FStype  Options         Dump    Pass#
      /dev/ada0p2             none    swap    sw              0       0
      

      regarding the counter, is there any way to confirm this?

      thanks again

        I would not worry about the wear too much. According to the data sheet that drive is good for 160TB of writes. Or about 4,000 days at 1.5GB/hour.

          You are using ZFS so the fstab is no longer required to mount those.

          You can probably see something useful with the correct incantation of iostat.

            thanks

            im running this command. please correct me if im wrong.

            top -m io
            

            im seeing some casual activity spiking (100%) under php, suricata, vnstat and cron but nothing constant

            this is the iostat output

            # 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
               0     2  0.00   0  0.00  23.75  20  0.47   0.40   0  0.00   2  0  0  0 97

              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

                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:

                                i finally reinstalled everything with UFS. so far, the only think i disabled was suricata

                                these are my numbers so far. ill keep testing and report back

                                  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
