My thoughts:
Like the WD-12, this drive is worthy of praise. IBM really made a great showing with their early microwinchester offerings, and the four platter WD-25 is no exception. There are very few 4 disk drives in this era, and IBM's is certainly the best. I recommend it for both it's low cost, high performance, high reliability, wonderful sound, and for just how common it is.
