This is exactly what I have. My main boot and applications drive is an SSD and I have all my actual samples stored on a 10,000rpm Western Digital Velociraptor drive, so I get the best of both worlds, either of the drives I am using is much faster than a standard 7,200 platter drive. I have about 20,000+ samples or so and Mediabay really isn’t that bad for me tbh.
Best of luck on getting yourself sorted however.
