We have flash caches (NVMe) in the machines, but the long-term storage devices are spindle--PMR and SMR.

I cannot disclose, exactly, but it is well below any other public price I've seen.
- voltagex_ 11y agoSo NVMe is "ready for production"? Do you think you'd use it at home, or only in the enterprise?
- jamwt 11y agoI mean, if at home you need 400k IOPS, 1GB/s of writes, and 2.2GB/s of reads... go for it! I sure don't, but more power to you. :-)
- voltagex_ 11y agoI'm tempted to get one and set it up as some kind of cache in my NAS. I'm already in silly territory with it now, anyway. 1GB/s of writes sounds crazy though - I haven't got anything that can write to it that fast!
- stock_toaster 11y agoI have a PCIe NVMe card (with a Samsung 950 pro M.2 in it) in my home server, which serves as an L2arc device for a ZFS pool. It is pretty nice. Runs a bit warm though.
- voltagex_ 11y agoWe are now well offtopic but I've seen some advice recently that advises using an SLOG rather than L2ARC for a home NAS.
- chronid 11y agoI think that a home nas would have a lot of async writes and very few/none sync writes. So a ZIL dedicated device (the SLOG) is not really useful/helpful. I'm not sure even if you really need an L2ARC device, just slap 8/16Gb of RAM on it and you will be happy... Obviously if you are playing seriously with VMs and databases and whatever else both of those (SLOG/L2ARC) may become important for you, I'm going for the "i'm just using this to store my raw-format photos, backups for the taxes and other big files" kind of usage here. :)
- voltagex_ 11y agoYou don't have any contact details but I'd definitely like to talk to you more about home NAS.
- scurvy 11y agoNVMe's lower latency is great. I've never really known how "slow" regular SATA/SAS SSD's were until I used NVMe ones.
- gbrayut 11y agoWe have been primarily using Intel NVMe storage for our database servers since fall of 2014 with no major complaints. Our high end desktop/laptop systems are also using the latest Samsung NVMe M.2 drives which are screaming fast.
- rwg 11y agoJust to put a number to "screaming fast", 2.5 GB/s sequential reads averaged across the entire drive on a Samsung 950 Pro NVMe SSD: https://pbs.twimg.com/media/CaMhc2oVAAE4q3q.jpg:large https://pbs.twimg.com/media/CaMhc2oVAAE4q3q.jpg:large
- toyg 11y agoI put it in production, and it's something else. Whether I'd use it at home depends entirely on how rich I feel I am ;)
- zbjornson 11y agoAside, Google Cloud has NVMe available on almost all machine types if you want to play with it [1]. [1] https://cloud.google.com/compute/docs/disks/local-ssd https://cloud.google.com/compute/docs/disks/local-ssd
