We used them with read caching controllers - some fancy board with lots of RAM with a Motorola 68020 onboard but they caused more issues than the performance advantage. Also remember ESDI was a pain to setup - it was a hack on ST506 so there was startup software to patch the BIOS you had to run to do the proper translation from head/cylinders to blocks done.

You are right, but for a few years, until IDE/ATA became available, the ESDI drives offered faster and bigger HDDs than anything available on the MFM Seagate interface, at still decent prices.
