This hard drive has definitely the WAF (Women Acceptance Factor)! It fits perfectly to our visually MacMini. We had both now for a while above the other (disk above) installed. Unfortunately, this is how we had recently notice affects the wireless antenna of MacMini negative. Meanwhile, the hard drive is again next to it and everything is fine! We use the disk for Time Machine backups and for media data. Our Eye TV library is there. When paused films she needs a second before it is again fully there, but the break is short and not disturbing. The blue indicator light is quite bright, but that does not detract from my star rating! Very good hard drive and the WAF is worth the money!
