Какой поставил в итоге? Я так понял, с random access типом нагрузки
лучше ставить побольше, чтобы один конкретный read/write обслуживался
одним, а не несколькими винтами. В ccd(4) вот что пишут:
For random-access oriented workloads, such as news servers, a larger in-
terleave factor (e.g., 65,536) is more desirable. Note that there isn't
much ccd can do to speed up applications that are seek-time limited.
Larger interleave factors will at least reduce the chance of having to
seek two disk-heads to read one directory or a file.
