[QUOTE="bobtomay, post: 1643547, member: 24160"] First issue - transferring or copying pictures from a CF card to the internal hard drive. imho - with 6GB RAM already, I don't know that either upping the RAM or the CPU is going to have much affect on transfer speed. The primary issue is the read and write speed of the devices in question. Have you tested your 2 computers using the exact same CF card and reader and the same 500 pics via FW and timed the transfer speed of one machine vs the other? And since you're using Lightroom to import them, both machines need to be running the same version of Lightroom. I'd be interested in seeing that result. Testing is the only way to know one is faster at a task than the other. The major difference between your 2 iMacs related to transfer speed is the 21" has a 3 Gbps SATA with a hard drive and the 27" is using a 6 Gbps SATA and a PCIe with either a Fusion drive (HD and SSD) or an SSD - whichever one you bought with it. I have a hard time believing FW could saturate that 3 Gbps bus on the 21", but actual testing would show whether that is the case. There is one other thing to consider. The 21" has been in use for what, 4 years now you've been using it for this? Have you ever looked at the drive with a defrag tool to see the condition of the free space on that machine? Even if you're running 40% free space on it, if you've never defragged it, that free space "is" going to be spread out from one end of the drive to the other. Fragmented free space is definitely an issue when trying to copy large amounts of data to a drive - slowing down the transfer speed as the arms in that mechanical drive are having to move all over the platters instead of having contiguous free space available to write to. If you've got the 3 TB Fusion drive in the 27" iMac, I sort of doubt you have any issue with contiguous free space yet. [/QUOTE]
