Under the pressure of public opinion, Toshiba, Xishu and Seagate have to admit that there is a mix of CMR and SMR in their hard disk. Compared with the other two,Before Toshiba, only 1 series of hard disks were exposed to SMRNow, Toshiba has changed its design. There are four series of hard disks, including 2.5-inch hard disks, which are SMR hard disks.
Before that, Toshiba recognized that the SMR hard disk is mainly DT02 series, and 4tb and 6tb use SMR technology, which is conscience compared with the other two.
However, this is not the case. There are four series of hard disks using SMR technology, as follows:
