Calibre performance on those libraries is faster than the same libraries on an internal SATA2.0 spinning disk drive . That said, the performance on the internal SATA 2.0 disk is more than good enough.
Have you checked the speed of the USB3.0 flash drive. Here is a review of some speed testers ==>> 6 Tools to Test Read and Write Speed of USB Flash Drives
Try copying the 400+ books to an empty library without any existing custom columns and see how that goes. I have known composite columns to slow things down, but I hasten to add a) only on large libraries, and b) since Calibre 1.0 even those situations have gone away.

I have 2 huge Calibre libraries, 168 211 books on main one (181 GB), all books from Gutenberg.org in epub and mobi formats (I update it weekly, so around 45 500 books right now (I am using the main one, can't switch to check
(83 GB) )
Both libraries are on a SAMSUNG HD103UJ S-ATA II (7200 rpm)
I back them up to an external USB drive and what takes around 19 hours.
I Have libraries databases and Calibre temp folder in a "persistent" RamDisk of 4GB (using symlinks to fool Calibre). These databases are backed up every 60 minutes to another local disk (not the usb one)
The software I use for the ramdisk is freeware, and no nags or anything annoying, SoftPerfect RamDisk (
http://www.softperfect.com/)
The only slow down i notice is when Calibre starts up. It will take about 2 minutes to show the user interface. After that it is fast even when I ask it to do nested searches. or update metadata in bulk.
Once a week, I use MyDefrag do defragment this partition, with the preset "Data disk Monthly" (MyDefrag is a free scriptable defragmenter for windows)
And I am very happy with the overall performance of Calibre.
I am sorry if I didn't explain something properly, I am not a native English speaker and I am still learning English at school.
