I am a photographer and mostly work on the road with my 2011 Macbook Pro 17, with a 3G OWC 1TB SSD in the optical bay for Lightroom catalogs and a Samsung 1TB 850 Pro in the hard drive bay with one partition for my system and another for my User directory. Theres no doubt its useful life has been extended by SSDs, and I need the storage, so no retina for me anyway, back to my Mac Pro, which I dont use as often, but I would like to eek some life out of, too. I have been buying some upgrades; Sonnet Pro Card, USB Card, SSDs. I may be missing a trick or two when it comes to the best setup, so any advice gratefully received. Predictably, I mainly work in Lightroom and Photoshop. The LR catalogs and images are all on the RAID0 Hard Drives, my system and Home folder are on the Sonnet Pro. OSX10.9.5 2008 Mac Pro 3,1 2 x 2.8GHz Quad Core 2x4TB WD Black in RAID0 2x4TB WD Red in RAID0 Card slot #1 (PCIe 2.0 x16) NVIDEA GeForce 8800GT Card slot #2 (PCIe 2.0 x16) Sonnet Tempo SSD Pro Plus with 2x 512GB Samsung 840 Pro in RAID0, with a 100gb partition for my boot volume Macintosh System and a 923GB partition for my Home directory; 950MB/s read. Card slot #3 (PCIe 1.0 x4) Inateck 4 Ports PCI-E USB 3.0 Expansion Card Card slot #4 (PCIe 1.0 x4) cheap PCIE to SATA III and eSATA CONTROLLER CARD, ASM1061, connected to eSATA HD dock (this card lets me hot swap drives in the dock, whereas the eSATA ports on the Sonnet Pro dont). Link Speed 6 Gigabit, negotiated speed 1.5 Gigabit, due to the dock I imagine; I can get 6 Gigabit link on an internal SSD, though only in slot #1 and #2. I am about to install 1x 128GB Samsung 830 and 1x 120GB Samsung 840 EVO in RAID0 in the lower optical bay, connected to the two sata ports on the motherboard, to use as a scratch/cache disk for PS and LR. I am about to upgrade my RAM from 12GB to 32GB with cheap RAM from eBay (fingers crossed). Im a little unsure of how best to set up my hard drive bays; Id like to have around 6TB of storage for my LR catalogs, and the rest can be assigned to safety backups and additional storage. Not sure which HDs to use, either; the REDs are noticeably quieter, but the BLACKs measure 280MB/s read vs. 200MB/s for the REDs. Should I assign a partition on the Sonnet Pro for any LR catalog I am working on (with the images on the hard drives)? I believe this might speed things up in LR, but perhaps not as its also the boot card (currently the catalogs are with the images on the Hard Drives). Or should the working catalog go on the scratch disks below the optical bay? And finally, I might like to try a little Bootcamp and Windows in the future, if that allowed for some modest gaming. As said, any tips appreciated!
