especially when the mx500 is only $5 more on amazon and neweggDoesn't appear to be a great alternative to other drives already on the market. I'd rather spend the extra on an MX500 for the better warranty alone. I use a 1tb MX500, for extra storage, in my laptop. If you can use M.2 NVME, and are on a tight budget, though, the 660p is kind of a no brainer. I have had no complaints, with system performance, with the 1tb, that I have in my desktop.
