I 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.
