      Me too! Must be quite busy, anyway I'm happy to wait

      • same, next one said

        ""Sorry, we need to prepare the goods, it may be delayed for shipment, About a week""

        Got my 18Tb today. running test today. Booted 10 times. power on time 1114 days. Cannot see the written/read data in HDD sentinel.

  • They had a public holidays aswell 1st to 5th may. Just got reply on teams. They are probably glad to be back and going through our emails lol.

  • I got the same email. Someone is copying pasting a lot :-)
    Not a problem though, can wait.

    My 18tb just got shipped. Just the 14 left to ship. Its all happening.

    • All been shipped now.

  • My order has been shipped, but it shows that the item is in Sydney. I originally thought it was being shipped from overseas.

    • All mine also shipped from Sydney (3 orders, one arrived the other day. Placed that before this deal). They must have Australian stock, makes sense as lot of hdd sold here and must be cheaper for them to send down a big batch and then distribute it.

    Just received mine in Melb

    Drive 1 (16TB) - 21,120 hrs
    Drive 2 (16TB) - 25,304 hrs
    Drive 3 (16TB) - 21,176 hrs

      Mine arrived today. Similar time. The 18tb had less read write then the 14tb ones. 14tb between 35-45tb read/write. Running full test on them now.

      Drive 1 (16TB) - 27,612
      Drive 2 (16TB) - 21,672

      Bit of a mixed bag, both of them noisy though even when idle

      • That's unfortunate. I was led to believe that the HC550's are some of the quietest enterprise drives out there (in comparison to Toshiba and Seagate).

        Are these your first HC550s, or do you have others to compare against for noise?

  • This is back in stock but at $293.. gees where are the low prices gone to

    the 14TB isn't a bad price

    • I don’t think the 14TB is good comparatively.

      It’s an earlier model HC530 and so older than the HC550s. The bathtub curve is a real (statistical) thing for HDDs, and you have to account for how many years of use your drives had in a data centre and so how many years is likely left for you.

      So a HC530 should have spent longer in use than a HC550, and naturally be significantly cheaper per TB.

      Tech wise, I prefer the HC530. It’s proven tech compared to the new EAMR in HC550. Newer data centre drives statistically have more life on them than older data centre drives tho. So, pay less for HC530 unless you know it has less hours on it.

      • I picked up the 14tb as it will form part of an array with other smaller drives, so the extra capacity is not needed. Will see how many hours are on it when it arrives

          @Eatoff
          Got a 14tb as well.
          Power on time 37699 (4.3 years)
          Built 24th June 2020.
          52tb written
          192tb read
          Running full test now. Finish in 3 or so hours. Let know here if any issues. So far no drama. The 18tb had much less read write on them.

          • @Mikael: That is a lot of hours. Maybe I should have spent the extra $70 for the less hours. Will see when mine gets here. What software are you using to get the reads and writes? Would I be able to use a USB dock to get that data still?

            • @Eatoff: Yes, I use dock. And HDD Sentinel pro I got on a deal from here. Hours are fine as they more than likely been in datacentre most time. I bet most drives from them have around same time. Data is fine too. They are built for 500tb/year i believe.
              The drive came back fine. Rebuilding my unRaid atm.

              • @Mikael: Thanks for the advice. Maybe I'll grab a second to upgrade to raid 6 in the process.

                I was using unraid, but needed too much tinkering for me, so I switched to Synology, but got tired of the noise, so just picked up a UNAS to go in a rack in the garage

                • +1

                  @Eatoff: First time using unRaid and like it so far, few months now. Took a while to wrap my head around it, especially shares. Had/have QNAP too as backup for crusial data.
                  I don't game much so used that PC. Works fine for me. Just upgrading disks in it.

                  • @Mikael: So, according to HD sentinel, my 14tb that arrived today has 1340 power on days, and 23 total start stop count. Max temperature it's seen is 43c. Reports no issues whatsoever, so that's a win I think

                    • @Eatoff: Not bad at all. Mine had similar. Now the temperature is higher here though as so many drives and cooling not the best. Around 47-49 degrees. Doing lot of transfers ATM though.

    My two 16TB had these stats:

    Power-on hours: 27,433 hours
    Power-on counts: 31 cycles
    Total data written: 46.52 TB
    Total data read: 106.45 TB

    Power-on hours: 21,795 hours
    Power-on counts: 30 cycles
    Total data written: 41.73 TB
    Total data read: 33.44 TB

    I am getting another two, can't decide if I want to go with RAIDZ1 or just 2 mirrors.

    • +1

      RaidZ1 vs mirrors is the same debate I'm having.

      It's worth noting that in ZFS, you can remove a vdev from your pool so long as all of your vdevs are mirrors (there are other considerations, but that's a big one) and you have enough spare capacity to store the data. If you have any RaidZ vdevs whatsoever then you're stuck with every vdev in your pool as you created them. If you decide to reconfigure your storage pool later, then you can't migrate from RaidZ1 to RaidZ2 or decide to add data drives to a vdev. You have to store all of your data elsewhere, destroy your pool, rebuild it, and then copy your data back in.

      That's why I'm probably going to start with mirrored vdevs while I build up my storage solution. That way I can maintain flexibility until I reach a point where I feel comfortable moving to a long term RaidZ configuration.

      It's annoying that if you lose a vdev, then you lose your entire pool, but mirrors and hotspares should help avoid that becoming a problem.

      Thanks, I've been checking the prices multiple times per day. They finally dropped from $293ish to $285ish today. That's not as low as the sale price here, but it is enough for me to order some.

      • +1

        Got a few since before too. I know the 18tb is $327 ($18.16/TB). I went that way instead. I know bit more per TB. Also found the 18tb I got had less write/read data then the 16. The 14 had the most of that I got so far.
        Don't need to upgrade more ATM. Got 50tb free with parity on unRaid and upgraded reolink NVR. My old QNAP got 4 4tb. But just for crucial backups that runs weekly and sync up to backup folder on unRaid.

        • I was eying the 18TB too. I’ve already got some 16TB tho, so it’s more flexible to stick with that size unless I’m certain to create a new vdev.

          That’s the Unraid vs zfs trade off.

          • @yak: Taken me so long to rebuild the parity and array. As needed few dockers running it took longer. Just to fix a corrupted Plex database now. Mov d lots of data between the drives and must've accidently moved something in Plex I shouldnt lol.

            • @Mikael: I currently (Synology) keep all of my docker files and databases on SSD. I'm planning on following that philosophy with my new DIY NAS too: Media files on HDD with ZFS and all of my OS, containers, etc on SSD with snapshots and some sort of backup system in place.

              • @yak: Yeah, got 1tb nvme as cache and VM's on another 4tb nvme. Also dockers on nvme. All downloads on cache during the day and moving at night to array.
                48gb ram and runninf on amd 5800x. I know amd not the best for PLEX but it works fine for me. Automatic downloads and if in watchlist it gets it to Plex. Watcharr through Usenet. Also works for friends adding. Just is if they add a series it downloads everything lol. Settings but couldn't be bothered to look into it yet.
