Watched a install video about installing this into a Synology DS425 NAS Installation went so smooth that I had the sinking feeling I had done something incorrectly That was far from the truth and this module was recognized and used as if it were factory installed. As far as knowing if I saw any speed or lag difference between the original 2g memory and the now 6g I’ll never now because this was installed before ever firing up the NAS It was received well packaged and very speedy delivery considering I ordered just before Bew Years Day
