Be very aware of buying this product from OWC. I bought two mini stack STX for the purpose of daisy chaining them and having two simple hard drives. There was no need for performance, just file access. I started having access issues to the drives and also then noticed in the settings for Thunderbolt bus devices ports on each STX showed "no device device connected" even though there was an iPad Pro 13, new MacBook Pro, a TB lacie drive and second Lacie drive.
After weeks of back and forth the folks at OWC say the mini STXs should not be daisy chained and each one needs to be directly connected to my mac (iMac 2019) . As this was the major reason I bought these and I was told by OWC when I bought them Thunderbolt daisy chaining was supported. They have never figured out why the second third and port devices continue to show up as "no device connected" as well.
