Data buffer The disk drive uses a 512 KB or 2 MB data buffer to transfer data between the host and the disk media In combination with the read ahead cache system described in item 3 and the write cache described in item 6 the buffer contributes to efficient I O processing Read ahead cache system After the execution of a disk read command the disk drive automatically reads the subsequent data block and writes it to the data buffer read ahead operation This cache system enables fast data access The next disk read command would normally cause another disk access But if the read ahead data corresponds to the data requested by the next read command the data in the buffer can be transferred instead C141 E110 02EN 4 5 6 Master slave The disk drive can be connected to ATA interface as daisy chain configuration Drive 0 is a master device drive 1 is a slave device Error correction and retry by ECC If a recoverable error occurs the disk drive itself attempts error recovery The 42 bytes ECC has improved buffer error correction for correctable data errors Write cache When the disk drive receives a write command the disk drive posts the command completion at completion of transferring data to the data buffer completion of writing to the disk media This feature reduces the access time at writing C141 E110 02EN 1 3 1 2 Device Specifications 1 21 Specifications summary Table 1 1 shows the specifications
