Normally you’ve have to worry about cross-products when you retrieve the lines of two files, but I think we can assume each of these files has only one line?
Try
(name of it, lines of files "size" of it, lines of files "/device/vendor" of it, lines of files "/device/model" of it) of folders whose (name of it starts with "sd") of folder "/sys/block/"
And maybe bundle those together with
Concatenation "," of (item 0 of it; item 1 of it; item 2 of it; item 3 of it) of ...
