Is it perfect? No. But I have one of them in a Pentium 200 MHz system that I use a front-facing CF card slot as the primary means of storage, and I very much appreciate the audible feedback for disk activity. I just wish there was some mechanism to simulate more accurate sounds, but I digress.

P.S., Depending on the CF card, this machine runs Windows 9.x, Red Hat 6.2, OPENSTEP 4.0, or Apple Rhapsody DR2 hehe
