The IBM DFHS-M1A is a 1.12/2.25/4.51GB formatted capacity (at 512 bytes/sector) hard drive featuring an industry-standard interface with 50-pin ANSI SCSI-2 or 68-pin ANSI SCSI-3 single-ended or differential connectors, and an 80-pin single connector attachment (SCA). It offers a media data rate of 9.59/12.58 MB/s, 10 bands, a rotational speed of 7200 rpm, and a latency of 4.17ms. The average read seek time is 7.8ms for 1.12 and 2.25GB models, and 8.4ms for the 4.51GB model. It utilizes magneto-resistive heads and a PRML data channel (partial response maximum likelihood with digital filter) for robust data integrity. Key features include spindle synchronization, user-configurable block sizes, a 512KB multi-segmented dual-port data buffer, drive-supported SCSI bus terminator power, industry-standard mounting, low command overhead, read-ahead caching, write cache support, ECC on-the-fly, and predictive failure analysis. It is designed for data server applications and offers compatibility
