Excellent product, easy to use, hooked this to a MS-01 with Unraid for my hard disk storage. Works great over the 10gbps usb4/thunderbolt port on the ms-01. Trays easily remove with a tool-less approach to adding drives. Well worth every penny. Using 10TB HGST enterprise drives in 2 bays with no issues on heat, quiet and for usb4, will never saturate the entire speed of the connection. works with software defined raid or jbod. size comparison, just slightly larger than my Synology 920.

It is exactly as described in the description of product. No second thoughts on buying. Using it as partial RAID and simple storage for homelab. For mounting SSDs, screws are provided, this information is missed out in the product package contents. R/W Speeds match the described information.

I have two different NAS systems. Each time I upgrade the drives, I am left with smaller unused drives. This affordable unit lets me use these drives as a backup. Easy to set up, good price, good performance.
