That's smart! It gives you access to any filesystem under Windows with somewhat easy (?) ability to transfer between Windows partitions and external volumes mounted in WSL.
Not sure if I got your comment correctly, but this is rather not about existing drives (though it could be applied to them), but to have a dedicated drive running within WSL that has a native performance. WSL handles existing drives (those that are readable under windows and linux) as a network drive using the 9p protocol. And, frankly, the performance sucks. E.g. I only reached write speeds of ~125MB/s when using 9p (while the disk is NTFS formatted and encrypted with Bitlocker), while the native LUKS encryption + ext4 reached 460MB/s. Using this approach transfer between Windows and Linux still would be slow though.
Thinking about that...I should probably have mentioned this in the article.
