    @cwt Thanks for taking the time to break it all down in such detail, I really appreciate it. Thanks, I'll have a read while I wait for my Enterprise drives to arrive.

    High peak speeds on consumer NVMe look great in benchmarks but don’t matter in real workloads. Enterprise SSDs are built for consistency, with stable performance even under sustained load, while desktop drives quickly drop off once their cache is...

    And I have to ask before committing to the money, with the following in mind what advantages am I going to see with high end desktop TLC like FireCuda, 990 Pro, T500 vs enterprise hardware; R730xd is limited to PCIE 3 x16 bifurcated to 4x per...

    OK so if I were to start again with, for example, 4 x Micron 7450 3.84TB for high performance and keep the existing disks for less demanding uses. What would be the best practice for configuring the Micron array? My instinct says RAIDZ1, I...

    Considering how much better enterprise drives do at small and sync writes I'd rather use them for a SLOG. Probably not needed if the main drives are DC ones already. I'm not sure if normal NVMe drives as SLOG would help that much to accelerate a...

    The theory was double redundancy for hardware failure but the IO performance is such a punish I would be better off moving to 2 separate mirrors. Noted, I started with code then second guessed myself and changed it to quotes. Back to the...

    I have used NVMe for SLOG in the past but from what I've read adding NVMe to the R730 is tricky, only specific drives supported in specific configurations. I was hoping some half decent SATA SSDs would be good enough but it would appear not...

    I had no idea the performance difference was so significant.

    Thanks team, I was wondering if RAIDZ may not be the correct choice.

    Hello Team, Trying to get the to bottom of underwhelming disk performance with ZFS, particularly random spikes of High IO wait. I know this topic has been done to death, I've tried tuning parameters, I have CPU and RAM to spare, on SSD disks but...
