Title: Inbetween moving from PC to MAC & how to sync a catalog
Post by: robertDthomas on August 07, 2012, 08:59:26 pm
Just bought a RMBP have been a PC user since way back.  My office computer is a PC and I have a single large catalog on this PC with 34,000 images which take up 780GB of image space and then there's the space required for the LR catalog itself and the previews.  The Mac has a 512 SSD and I plan on using the Mac for field work. Importing images to LR, editing and then transferring to my main catalog on my desktop when back in the office.  This I am pretty clear about which I believe would be to import the images from camera to LR on the Mac, edit and then when back in the office "export as catalog" from the Mac to a USB 3 external drive and then "import from another catalog" to the PC.  This I believe will transfer all the edits, keywording, collection work, etc. that I might do while in the field.  I will format the external drive in FAT 32 so it is read/writable by both platforms and since none of my images exceed 4GB I see no limitations to FAT 32.

Where things get a bit confusing to me is where I might want to do a bit of keywording or editing of previous shoots in the hotel or when having some downtime.  As the Mac does not have the hard drive space for the full catalog and all the other programs I will selectively move the images I want to 'carry with me' to the Mac.   With this I expect to transfer the images I might want to work on in the field ("export as catalog" from the PC and "Import from another catalog" on the Mac.)  I will probably use the external drive as the transport mechanism.  I know I can probably export the whole catalog to a 2TB portable drive and operate off that as my source for both the PC and MAC but I don't want to take the perfomance hit of operating off a 5400 rpm 2.5" external drive even if its connected via USB 3.0.  BTW I want a very portable solution so a Pegasus RAID 0 array will not be my choice.  I also want to see if I can export all my keyword structure to the Mac from the PC catalog so I have them handy for my keywording sessions.

I know a lot of questions but I have been searching the web, this and other forums and haven't come across a good solution or one that I understand.  Maybe I have the wrong idea of how to run across desktop and laptop with LR.  Can someone point me in the right direction??

If your laptop has an SSD drive, you might want to consider a small external drive for Lightroom ... there are some extremely small and light ones available ...

I'm planning on getting the one (http://www.promise.com/storage/raid_series.aspx?region=en-global&m=192&rsn1=40&rsn3=60) Michael talks about in his retina macbook pro article as soon as I can get my hands on one ..

I do something similar to what you describe:  import into LR on MacBook Pro, cull, tag, develop, etc. on the MBP, then move to the big catalog on the PC.  Things I've learned along the way:


Also, if you use the wired network and run 1Gbps ethernet then that is going to be a faster way to copy than using external drives: regardless of using USB3, the actual platters on mechanical drives aren't going to let you push data on/off the drive that fast.  Unless maybe you use an external SSD drive.  Also, using external drives implies a multi-step process:  Mount the drive on the Mac, export to there, unmount it, mount the drive on the PC, copy, unmount it.  Over the network you're just copying in one step, without the mount, unmount, mount unmount steps that also add time.

And if you find that you're not time-constrained enough to need the wired ethernet then it's even easier to do the copy over WiFi.

You're going to get a huge benefit from doing most of your work on the Mac's SSD.  I've found that when I'm done editing on the Mac that everything after that is not time-constrained.  You might discover the same thing.  I would start simple.  Don't try to go for mega-fast expensive external transfer drives until you prove to yourself that you actually need it.  And if you need it you'll make sure you appropriately solve problems that you really have.
