Ten cylinders is a small partition. Running Diskperfa will fragment that pretty fast. The test goes from smallest to largest block size leaving the partition fragrmented. The 2090 really shows its speed when it can use DMA to read/write multiple blocks to disk. With 30k bytes records and a fresh clean partition, it can lay 17 block on a track in one operation with the Fast File System. When the partition get fragmented, FFS can't find contiguous block, it is forced to do more operations. With 700k, you might be doing single block read/writes with will be about the smae speed as the old file system. Give your partitions some space (10 or 20 meg) and try again. Dak
