I just received my 2nd gen Drobo and have been playing around with it a bit. I’m using a Win7 PC (64-bit). My Drobo currently has two hard drives (both WD Caviar Green 7200 rpm drives). It’s connected via fw800 using the included cable. I saw on the support site that the recommended drivers are from unibrain, so those are the ones I started with. I’m finding that my sustained transfer speeds for large files is only about 30 MB/s. I then tried reverting back to the Windows drivers, and actually got slightly better speeds for large files (~35 MB/s). Both of these marks seem rather low. I am aware of the issues with Win7 and 1394b, but I guess I still expected to get speeds around 75-80 MB/s for transfers (especially with third party drivers). I feel like I should be able to get the speeds I’m getting with USB 2.0 or fw400 (but I haven’t tried it with those connection. Am I being naive? Is anyone having better luck than me with a similar setup. Are Macs much faster? Would my drobo be faster if I had 4 drives in it? Are there better drivers to check out?
I have searched these forums and found that, notably, at least one person thinks it’s not worth the pcie slot that the 1394b card takes up in a win7pc. Is that the consensus? And if so, would it be better to go with USB 2.0 or should I just get a fw 800-to-400 cable?
Thanks, and sorry for all the questions.
