RAID partitioning/drive testing
on Aug 15, 2010 at 12:51:28 pm


What are the considerations partitioning large external RAIDs? I've just put 2TB drives in my three RAID boxes so I'm thinking now of how best to organise them. I'm a film maker and photographer working with EX1 and HDCAM files in Final Cut and big layered Photoshop files. This is what I've got now:

Mac Pro,
Boot/application drive,
6TB internal RAID 0 for fast still image work,
18TB RAID 5 SAS run off an Areca 1680x for fast video work,
7.5TB eSATA and a 20TB eSATA RAID 5 boxes run off a HighPoint 2314 for backup and archiving.

Should I partition? If so, in what way? To what purpose?
Also, how should I test the drives before the RAID build? (I've run them through Disk Utility, checked I can write to and from them and am now doing a surface scan in Drive Genius. Is it worth doing this last step? (cos it's going to take about a week at this rate).
