This is PCIe, not USB. Although if OP does have an unused PCIe slot they didn’t mention in the post, I do agree a second-hand LSI card is by far the most cost-effective way to connect large amounts of SATA/SAS drives. And you get much better performance than USB as a bonus!





I mean, cheapest way I think would be to go on aliexpress and find the best price for a USB-SATA adapter and just buy a ton of them. Be careful with power consumption though, spinning up disks can be power hungry and your hub might not like it.
