With that setup your backend should normally be able to respond within
the ~4 (may be a bit less) second timeout. Have you checked your HD DMA 
settings? I know that some of the Maxtor drives can have acoustic 
management (hdparm -M) enabled by default, that can have quite an impact 
on HD seek times.
