I want to buy disk shelf from EBay and connect it to my existing NAS which is running TrueNAS on a Lenovo ThinkStation P520 Workstation 1X 3.70GHz W-2145. I already have 4 SAMSUNG 870 QVO SATA III SSD 4TB 2.5" in this PC that are connected directly to the motherboard via SATA cables. Id like to use 1 of these drives as a cache drive and then the rest move into the disk shelf and also purchase a few extra HDD’s and expand the storage.
What disk shelf and SAS cards does anyone recommend? I’d like to maximize the throughput of the existing SSD’s I’m going to move into there as well. Any help would be appreciated, thanks!
