Works previously without objection in a Synology DS215j (the hard disk is not on the compatibility list of Synology). It is a little louder than I'm used to from 2.5 inches Fesplatten, presumably due to 4 platters. Is moderately warm (39 ° C) with switched off ventilation. The thickness of 15 mm is in a Nas generally not a problem, but the 2.5 inch hard-drive bracket from Synology do not really fit for so thick plates. I can about the longevity previously not say anything, but once fully complete writing the hard disk and completely read has been promoted no errors to light.
