Having a single drive is slowing down reads as well, I think.
This depends upon how the RAID is set up.
A standard Linux RAID1 setup does not give better reading performance when reading large files than a single disk.
Maybe, if your system isn't doing anything but reading that one file...
I don't know if the RAID system is cleaver enough to save some seek time.
I don't think it is particularly smart, but it can alternate reads between drives so the heads can be seeking to different places simultaneously. Of course intermingled writes will force the heads to the same place on both, though.
