No answers, just more questions...
I believe that two drives are better than one that is partitioned. Redundancy has its benefits.
I'm not a hardware person: I'm more comfortable with an axe than a soldering iron. Please bear with my ignorance for a moment.
As I understand it, two disks on one controller will only operate one at a time. Two disks on two controllers will both operate at the same time. So, with one controller, if one was to copy a huge file, such as an image, one disk would read, then stop while the other disk would write. When the writing finishes on the destination disk, the reading resumes on the source disk. With two controllers, both disks will be working, halving the data transfer time.
Sounds like a second controller card comes with considerable performance increases at a relatively low cost. Maybe worth looking into.
Cheers, PW.
P.S. Maybe I'm wrong here, and it's two cables instead of two controllers. |
