Most Mac Pro models are not compute-bound. They have lots of extra compute power that is not being used. Most Mac Pros are I/O bound.
Are you already running 64-bit? You should be.
Your next mission is to determine if your Mac has enough RAM:
Next you need to see if your processor are running flat-out:
Seek time on a rotating drive is not negligible. The about 20 milliseconds must be endured every time you need something different from the drive. To maximize performance, you need to NOT move the heads away from what you are reading or writing.
A drive for the source file.
a drive for the destination file.
a separate drive for the System stuff, so that its habit of going out for a little of this or that does not derail the other drives and cost you file access time.
RAID drives get their performance boost by overlapping I/O. One drive is transferring data while the other drive is seeking. This only works AFTER you have given each source, destination, or System its own drive. A RAID with all three on it is NO FASTER in practice than regular drives!!
SSD can give a modest incremental performance boost to your System drive for a large outlay of cash. RAIDing it as well does improve it slightly, but it is a modest improvement for a very large outlay of cash.
The last is the first 200MB/sec 10K VR
The price of your more standard WD Black 1TB while nice is still $119 and not in the same league for a small fast boot drive.
Why Crucial 4m and others like Intel 520 and Samsung 830 are still popular, recommended, and no going back for every one else.
Crucial m4 128GB $109
$95 for the WD Black 500GB
- seems same discussion on another forum...
I am running Lion and certainly Lightroom is being launched in 64-bit mode. Enough RAM? So 8GB is not enough for running Lightroom?
I don't know if in real life adding a new processor will result in a significant performance boost but at least here says that using it with all memory sockets filled gives you almost the double performance.
Regarding to SSD drives, I have read many issues regarding to speed, when they were using 25nm rather than 34nm or something like that. I cannot remember the numbers. I like also OCZ but there were problems also with Vertex 3 drives so honestly I don't know what to do. I would appreciate if you could tell me which brand is the best one for using it in my MAC.
using it with all memory sockets filled gives you almost the double performance.
You are talking about the frosting and missing the cake. The memory cycles a little faster with all sockets filled. But the jobs run A LOT faster overall if they have enough memory, even if half the sockets are empty!
Only YOU can see whether you have enough RAM to run your Lightroom jobs without substantial Pageouts. Fire up Activity Monitor and watch it.
