Since I've been running LR (currently 3.6) under Windows XP on a 6 year old HP desktop with an AMD dual core processer I just purchased a Dell XPS 8500 and plan to install LR 4.1 and move my catalogs and images to this new machine.
The machine came with a 1 TB SATA || hard disk, and I've installed a 240 GB SATA III SSD and installed Windows 7 on it. I currently have my images on an external 1.5 TB eSATA hard disk connected to the old computer, and expect to connect it to new computer the same way.
Currently (in LR 3.6) I find I spend most of my time in the library module culling images and selecting a small number to develop. I generate 100% previews for a shoot, and then switch between grid, loupe, and compare views, frequently zooming to 100% to check and compare critical focus. Since I develop a much smaller number for photos, and typically do pretty minimal processing, don't spend as much time in the develop module. Assuming that I'll do the same thing in LR 4.1, my top priority is library and performance, particularly when zoomed to 100%, and secondarily develop performance.
My question is, to get the best performance, where (on the SSD, internal hard disk, or external hard disk) should I
hopefully the rest of the community responds with some of the specifics you are asking, but take a look at
Lightroom's Help- "optimize performance":
-hope these help in the meantime,
I had already read the first link (in fact I have a shortcut to it on my desktop) and plan to incorporate some of its recommendations into my setup, but it doesn't go into much detail about the tradeoffs for placement of LR catalog, ACR cache, and images.
The second link doesn't have much new except for item 8 "Keep Catalogs Small", which recommends less an 10000 images per catalog and multiple catalogs which contradicts what I have read here.
I found the last link useless (I already know to to tell and control where my images are stored).
Anyone else have any suggestions about where to put the LR catalog, ACR cache, and images to get the best performance, particularly for the library module?
