Happy New Year, all! I will spend the rest of the week reorganizing my digital life around the new 27" iMac that appeared on my doorstep yesterday. The transition didn't start out too smoothly, but the initial brain transplant from my 4-year-old MacPro tower is now complete. I should receive the 3rd party memory upgrade and a new Drobo 5D tomorrow or the next day, too.
When it's all up and running I'll give you a fuller report, but right now with only 8GB of RAM and all my D800 files off on external FireWire drives communicating via a FireWire-to-Thunderbolt adapter, the speed of rendering 1:1 in LR4 is noticeably faster but not astoundingly so. That should improve markedly when the working files are resident in the onboard Fusion drive (3TB of rotating disk storage with an adjunct solid state disk of 128GB) and all 32GB of RAM are installed; we'll see about files on the Drobo, which has both an adjunct SSD as well as the purported benefits of fast disk-array access and will be connected natively via Thunderbolt.
Thankfully, the new 27" iMacs are still user-upgradable, with four DIMM slots accessible behind a cleverly-designed hatch just above the power cord.
Sir Steve: Thanks much for your ongoing reports on the new 27" iMac. Later this year I will be upgrading my system and had anticipated going with a Mac Pro tower and a NEC monitor/display. With your long experience with a Mac Pro tower, I'll be paying great attention to your comparisons and conclusions regarding the new iMac. Issues like monitor calibration, rendering speed, and your Drobo arrangement will be of great interest. Count me as very interested
