Monitoring IOPS of the scrub on the TrueNAS ZFS striped mirror array with 12 8TB HGST HDDs and two mirrored 1.9TB SK Hynix PE6110 NVMes for SLOG and metadata. 2.8GB/s read speed? I'll take it! #TrueNAS #Homelab #Server #Networking #Linux

Used high endurance enterprise NVMes for your homelab have gotten down to some pretty good prices over the past year. Right now you can pick up Gen3 SK hynix PE6110 1.92TB NVMes for ~$120, or about the same price as new 2TB Gen4 consumer NVMes. While not reaching the insane 7,000 MB/s read performance of Gen4 consumer drives, the Gen3 3,200 MB/s read and 1,900 MB/s write speed, coupled with sky-high endurance, makes them a perfect fit for heavy write applications. For example, a Samsung 990 Pro or WD Black SN850X has a TBW (amount of data written before potential failure under warranty) of 1,200 TB. In contrast, the SK hynix PE6110 boasts a massive 3,504 TB TBW—nearly 3x the endurance! #NVMe #SKhynix #SSD #Enterprise #Homelab

Thinking upgrading to 10GbE for your homelab isn't enough? How about 25GbE? How about 100GbE? The MikroTik CRS510-8XS-2XQ-IN is an absolute beast of a switch with 8x 25GbE SFP28 ports and 2x 100GbE QSFP ports for nearly all the high-bandwidth connections you'd ever need. Power consumption with no load comes in at a loooow 14W. While cost new is pushing $900, you can find these units used for around $400-500. Well worth it for would likely be your forever big-bandwidth switch. #MikroTik #CRS510 #25Gb #100Gb #Homelab
