2TB 7200rpm Western Digital drive, good internal drive for documents?

hi again,

Ok, I think I've reach some conclusions about how I plan to arrange my drives internally, in my Mac Pro, in a cost-effective manner (to start with):

In the first two bays (or maybe the optical bay and bay 1):
System Drive: 640gb HD (the one it ships with)
Documents drive: 3.5" SATA 2TB Western Digital drive

In the next two available bays (as duplicates of above):

System Drive: 2.5" SATA 500gb HD (as that's what I already use for back ups, will need a bracket to fit it in the MP)
Documents drive: 3.5" SATA 2TB Western Digital drive

When my budget allows it, I'll get another two HDs (one 500gb or 640gb and the other 2TB) for backups to be kept off-site.

The 3.5" SATA 2TB Western Digital drive I'm looking at has the following specs:

- Capacity: 2 TB
- Interface: SATA 3 Gb/s
- Spindle Speed: 7,200 RPM (nominal)
- Maximum Internal Transfer Rate: 1156 Mbits/s (Max)
- Maximum External Transfer Rate: 3 Gb/s (Max)
- Buffer Size: 64 MB
- Average Seek Time: 8.9 ms
- Warranty: 3 Years
- Weight: 0.73kg

here's the page I'm getting that from: https://www.pcdiy.com.au/product_in...10752&osCsid=151627a07003bfac501da3a72e387162

can anyone see any gaping holes in my plan? I'm new to this.

One that I can see is that my in-use system drive is 140gb larger than the one I'm backing up to. Eventually I'd replace both with the same size HD - when I'm in a position to do so.

But for now, it means I only have to buy two HDs to get started (2x2TB 3.5" drives).

Any thoughts or suggestions?

cheers : )

ok, so they're a bit pricier, but here is the 64MB, 7200rpm 2TB WD Caviar Black you were talking about:

http://www.itestate.com.au/pages/pr...;jsessionid=0954ACFBDBD75D16BAF65B7DE8BE707A#

this would be better off as an internal document drive?

When I say 'Documents' I mean stuff like Albeton sets and audio recordings, as well as audio/sample libraries. That stuff can eat up a looot of space.

Currently I have all my stuff on a 500gb drive, but I've got sound libraries and stuff I haven't installed yet, cause Im out of space (have two that eat up 40Gb each).

Couldn't afford two Caviar blacks at the moment, but I could get one, and keep backing up to my current drives (they should hold it all for a while), while I save my pennies.

Can anyone vouch for the 3.5" SATA 2TB WD caviar black?

thanks for the advice so far guys. good to have some other people's inputs.
cheers : )
