Question about hard drive performance
I have an Early 2008 Mac Pro (3,1) 2x 2.8 Ghz. I am currently using a 240 GB Mercury Accelsior PCI SSD as my boot drive (with OS X & applications) and triple RAID0 (with 3 750 GB Western Digital drives) as my Data drive (with docs, pictures, video, music). I have 18 GB of RAM.
I do a lot of photography work so I am looking to optimize performance in Lightroom and Photoshop. I also want a little more space on my Data drive.
I'm considering upgrading to a RAID0 with 2x 3 TB Seagate Barracuda (ST3000DM001), and then using the available 3rd bay for another 3 TB Barracuda I'd use for back-up.
Would this give me a significant performance improvement over the triple RAID0 I currently have?
