The installation guide that came with the EVO basic kit (just the drive basically) was not very informative to be honest. The first step features this usb to sata connection for some reason (as if this connector was something commonly laying around people's houses...). It doesn't explain why you have to do this, or what is supposed to happen at that stage. Only later, step five I think, it tells you to place the drive inside your computer and connect it the way you would expect. It bugged me immensely, because with all the fancy software and tech inside modern SSD's I couldn't just automatically rule out that this was in fact not necessary... Anyway, I'm glad that I don't have to go procure this cable, but I'm very curious why the step was included in the first place, and not just as an alternative connection. It was not presented as if it was intended for external usage...
