Yeah the adpater is working good for me thus far since ive had it. My machine hasnt had a power drain but I have a P4000 so idk if its just because of that. I do have another question regarding the adapter though. I recently bought an M18x R1 for like 85$. Like MAD cheap. Just got it today and while its got some cosmetic damage, it runs pretty good. I outright refuse to use the default HDD cable they give you to use since ive had nothing but problems using that setup with that crappy cable with that crap port on the R2 (Only using it temporary as to see if the machine ran) and the R1 is basically the same format but smaller. I want to use this adapter for this R1 as well. Will it work for an R1?
