Yeah, I think I agree with John. It sounds like given that you don't have real capacity requirements, I'm not sure the Drobo is the best solution for this, except that you already have it.
If performance is key, and it's small random I/O, a mirrored pair of SSDs would kick ass. -Adam On Tue, Dec 6, 2016 at 4:03 PM, John Stoffel <[email protected]> wrote: > > Craig> ...actually, I think it's very helpful. > > Craig> The array is currently grossly over-sized, but only holding > Craig> 105Gb of actual data.
