Western Digital details 14-platter 3.5-inch HAMR HDD designs with 140 TB and beyond

One problem with large hard drives , in my opinion is the interface speed has not changed - got faster than SATA III (6 Gb/s). A failure of such a drive would mean a enormous amount of data lost .... So obviously backup is absolutely essential
