Mac Pro 1,1 Feels Sluggish - shouldn't be. How to diagnose?

[barmann]

I hope this is not too OT, but this thread got me curious, so I ran some speed tests on my MP 3.1 .

The SSDs have been in use since late 2011, never more than about 60% full .

The Blackmagic results are radically different from the AJA test's, very odd .
Maybe an OWC (or similar) thing, as mentioned above, and here ?

Not if you look at the corresponding AJA results above the Blackmagic results, that's what baffels me .

Maybe the image isn't clear - the two screenshots on the left are of my 2x40GB/Raid0 system drive, the two on the right of my 60GB scratch disk ; top is AJA, bottom Blackmagic, 1GB test files each .

I ran a bunch of performance tests some time ago, mainly Photoshop and basic system stuff, and my SSDs deliver the expected improvements over my HDDs, even a 2x Velociraptor Raid0 (yes, she's getting old ).

I'm obviously not an expert, and don't understand the difference between both test programs, but my SSDs perform according to what the AJA numbers suggest, the Blackmagic results are way off .
