I do IT for a living so I tend to over research my tech purchases, but this one was time well spent.  This drive is fast enough with a generous 3TB which is what I wanted for the internal storage to our family computer. I do some fairly intense video editing with Final Cut using this drive as both the system drive and the scratch disks and saw very little lag in.One concern I'd heard with some of the other high capacity drives inside iMacs is that they are too loud, so the sound levels was probably my biggest concern.  After several months of all kinds of use I have yet to ever even hear the drive doing anything.  Phew!Its a great drive and I got it for a great price! 

Question: Is this drive safety?
Answer: very little lag in
