While the 2009 Mac Pro was not outrageously noisy, it still was far from silent. What I found particularly attractive was its promise of near-silent operation. I was reasonably happy with the 2009 Mac Pro, but of course, by that time it was getting a bit long in the tooth and I started lusting after the new Mac Pro. I had, in previous years, changed my startup drive from the conventional 1 TB hard drive that came with the Mac Pro to a 240GB Mercury EXTREME Pro 6G SSD from Other World Computing, and I had three conventional hard drives in the other three internal bays, as well as some external FireWire hard drives for backup. When the new Mac Pro was announced in 2013, I was still using a workstation consisting of a 2009 Mac Pro with 12 GB of RAM, two SuperDrives (one for Region 1 and one for Region 2), and two GeForce GT 120 video cards driving two 30″ Apple Cinema Displays (each with a native resolution of 2,560 x 1,600 pixels). Like many other professional Mac users, I suspect, I was quite relieved when Apple finally shared, in early April, with a select panel of writers who cover Apple news, their plans for the Mac Pro and, more generally speaking, for pro and “prosumer” users of Macintosh computers.
