There are utilities like Crystal Disk Mark for Windows that can help determine the performance of internal and external devices. I am certain there are similar utilities for the Mac. I have two monitors on my Windows PC and I open the windows task manager on one monitor and perform some tasks in Lightroom Classic on the other monitor and watch how my CPU, Memory, GPU, Disk, and Network are utilized. If Lightroom Classic is running slow it helps if you can determine where the bottle neck is. The Photo Taco Podcast web site provides a number of speed comparison for Lightroom Classic when using external drives. I hope to upgrade next year to a 14 inch MBP and an external monitor which will solve the drive formatting issues, but until then, I would appreciate any thoughts you may have on these issues. Should I jump to an NVME SSD for additional speed? Will it make a difference to LR? My SSD is about 3/4 full so I need more space. I can put LR and PS on it not problem, but if I want to access my photos and catalogue, I need to reformat it at FAT32 and put the catalogue on the SSD with the photos so that both OS' can read the SSD.ģ. It is a Microsoft Surface Pro 8, Core i7-1185G7, with 16GB RAM and 512 SSD. I stopped using 1:1 previews because they take up too much space.Ģ. Slow to boot, generate photos in the the Library grid and slow to load individual photos in the Library at full screen and 100%.

My goals are to make LR run faster and be able to use both a Mac and Windows OS (see below for the details).ġ. I have a few issues I need some advice on. All LR related photos are stored on an external 2TB SSD w/ a SATA III USC 3.1 Gen 2 connection. I store the LR catalogues on the internal drive which is a little over half full. I have a 2017 Core i7 27 inch iMac with 40GB RAM and 512GB internal storage.
