- What kind of performance (throughput) is typical for ESDI drives? I've
- got an Adaptec track-caching controller (64k cache) and an older CDC
- 182MB drive, running on a 486SX-25 machine.
-
- The seek time is very good -- something like 16ms according to all my
- benchmarks -- but the throughput isn't much better than my old MFM
- controller and drive with 1:1 interleave. The benchmarks say the ESDI
- system is giving me about 550kb/sec transfer rate -- the MFM system
- showed about 490kb/sec.
-
- Do these benchmarks understate the performance of my system, do I have
- something wrong, or is there really no advantage to ESDI?
