Aside from the drive, is it behaving/performing as you expected?
Too early to tell --- it didn't arrive until late this afternoon, so I only had a few hours to mess with it. Bottom line is I partitioned the .11 to 200/300 and put the OS on the faster 200G end of the newer drive. This leaves 300g for misc data on the slower portion of the platters. I then migrated all my settings from my MBP over to the new Mac Pro, and all went smoothly. Then I erased to oem .10 drive and set it up as my dedicated Time Machine drive. It was writing to Time Machine as I left.
Tomorrow I'll be adding the external eSATA extender from the extra two SATA ports on the MB and figuring out the rest of my drive strategy. I am considering striping two more of the .11 drives for faster reads and writes on my current image files, of course mirrored to an external for redundant back-up. My RAM should be here on Thursday, so that's when I'm going to load it up on processes and see if anything breaks.
FWIW I did pull the cover and feel each drive after an extended read off the .10 and write to the .11. The .10 felt pretty darn cool --- just warm to the touch --- yet I had expected it to be much warmer after reading some online reports about heat. Chalk up another plus for the .10. However, the real surprise was when I touched the .11 --- it was barely warmer than room temp, so it really does run cool! In either case, neither drive heated up to the point where the fans kicked on high.
Oh, here's a 10 page review of some drives, including a 1TB .11 and 500G .10 --- take it with a grain of salt unless the actual tests replicate things you do, but the sustained read and write times are what got my attention --- note that the seagate ES2 is the same as a .11, while ES is a .10 :

The hard fact is, Hitachi 1TB DESKSTAR continues to be the drive to beat on most performance fronts, while the WD 1TB GREEN is Queen of quiet, low power consumption and low heat.
Conclusion: If money isn't a concern, stripe (RAID0) a pair of Hitachi 1TB DESKSTARS for image read write, and back them up to a 1TB WD Green in an external enclosure. Then stripe another pair of Hitachis and partition the top 200G off for OS and use the rest as expensive (but fast) back-up... Those 5 drives and an external enclosure will cost you about $1500 at today's prices. Personally, I'll just live with the slightly slower read and writes and store my images on a single drive, mirrored (RAID1) to a back-up
