On your current box run the test suite, data, DB out of a RAM disk
or tmpfs. A clean chroot test environment on a 4-8GB RAM disk will
work faster than any HDD/SSD. And much cheaper too.
Sync the RAM disk state to HDD periodically so to ensure persistence.
Syncing can run in background to minimize performance impact.
There are several advantages in not touching disk. The Mailinator creator
discusses how he reaches extremely high performance on old hardware
using Java by running his app entirely out of RAM:
