^ That may be because nobody has tried your exact combination of SSD and iPod. Like I said a few post above, it depends on your specific combination of SSD and iPod. Spec may look the same/similar for different SSD's, but in reality one SSD works while the other may not.
I searched within this thread using the keyword "Mach" for you. This post is relevant (post #241 on page 17 from Headfier "r100"):

"An update concerning SSDs:
I bought a Mach Xtreme Technology MX-Nano 120GB ZIF SSD two weeks ago for my Classic.
After a lot of trial&error I conclude the following:
-This SSD does NOT work in Classics (tried it on two Classic 80GB's, same ata error in EmCORE)
-Bought an old used Video 30GB, the SSD works fine in this one (like promised in the specifications)
I'm both surprised and disappointed that this drive doesn't (seem to) work in Classics. I was looking forward to put it in the complete aluminium cage from a Classic instead of the partly plastic Video.
Does anyone know what makes the HDD in a Classic and Video different from each other?"

See what I was talking about? The same Mach SSD did not work in iPod Classic, but worked in iPod Video. While ProSeriesRacing (see previous page) had the opposite experience, wherein his Kingspec SSD worked in iPod Classic, but not in iPod Video.
