I'm interested in buying a 25-MHz 486 PC for software development (C under DOS, OS/2, and Unix) and want to pick the 'right' disk interface type. I assume that IDE is an 8-bit parallel interface. I know ESDI is a bit-serial interface defined for up to 24Mbits/sec. Could future IDE drives have an internal transfer rate >24Mbits/sec and can this interface handle external transfer rates in excess of 3 Mbytes/sec? If ESDI is still best, which controller is best: the Adaptec 2322D, Ultrastor 12F or other? Caching disk controllers are considered too expensive.
