How fast will a new MacPro Quad process a Canon1dsMk2 file to .tif and to a small jpeg (quickproof)?

Anyone try yet?

  I'm waiting for my new MacPro so don't know from own experience but I've been told it takes only 2 seconds.

  Mac Pro Quad Xeon 3,0
  C1 Pro 3.76
  OSX 10.4.9
  Canon1ds Mk II Raw File
  100 % Tiff (HQ) and 100% jpg (quick proof)
  
  9.4 seconds
  
  Lightroom: 3.7 sec (100% tiff only) CPU load ca. 80%
  C1 Pro: 8.2 sec (100% tiff only) CPU load 100%

  I discovered a 50% speed increase in the new Beta Version of C1.
  Same Configuration as before:
  
  Canon1ds Mk II Raw File to 100% Tiff
  
  C1 Beta 4: 5,8 sec
  C1 Pro: 8,2 sec
  
  I verified this with 10 Raw´s to uncompressed tiff:
  
  C1 Pro: 85 sec (100%)
  C1 Beta 4: 57 sec (150%)
  LR 1.1 : 34 sec (257%)
  
  Nor bad but Lightroom is still leading the race
  Maybe Hard Disk speed is also factor here for Cross System comparison .
  You have about 48 MB per File witch gives a total amount of 476 MB.
  I use a internal 2x 250 MB SATA striped Array.

  How much RAM do you have? I ordered a 2.66 unit, 8 additional Gigs RAM, two additional 500GB WD HD's. I plan to strip those additonal HDs as RAID 0 and place the Sessions there. Others have told me it is a good way to go.

  Hi jjlphoto,
  
  I have 8 GB RAM. I use a additional 250 internal HD as Backup Volume. I don't trust RAIDs 😉

  Uh, isn't this "I use a internal 2x 250 MB SATA striped Array." a RAID 1?

  jjlphoto,
  
  RAID 0 is super fast, especially if you use 4 drives... however if you lose any one of those drives all you files will be corrupted. If you can, try a Raid 5, that will give you both striping and parity, so if you lose a drive you can rebuild the info. It will not be a fast, but the security is fantastic.
  
  dneibert, striping alone would be Raid 0, RAID 1 is Mirror 😊

  RAID 5 is only tolerant of a single drive going down. Raid 5+1 or 6 are better ideas if the information is important. RAID 0 is horrible to store data but great for a scratch disk.
  
  If you have a 4 1TB drives set as RAID 5 and one goes down you have to wait for it to rebuilt an entire TB of data before you are safe again. If there is another error while rebuilding you'll lose everything because there is only one set of parity information.
