I think that’s a little too pricey for the 4 TB version at $899.  

Check out Amazon. A bare 4TB Sabrent NVMe SSD is $650 and good, bare Thunderbolt enclosures aren't cheap either. The only way to get the maximum speed of an NVMe SSD is to use a PCIe x4 interface in the enclosure. (I believe this is what OWC is using in these models but they aren't using them in all external TB enclosures.) USB4 drives (USB interface) are not as fast as Thunderbolt and even with the latest USB4 enclosure interface they are still slower than Thunderbolt.

If you read the fine print on the MacSale's website you'll see the maximum speed was achieved on a specialized Windows PCs.
