According to Tom’s Hardware, Seagate revealed its latest mechanical drive roadmap this week, saying its last PMR (perpendicular magnetic recording) mechanical drive will be 24TB and its first HAMR (heat-assisted magnetic recording) drive will have 32TB of capacity.
Seagate reportedly expects to launch a 24TB PMR drive in a few months, with a possible 28TB SMR drive thereafter.
Seagate’s first HAMR HDD will use 10 3.2TB disks, thus providing 32TB of capacity. After that, Seagate’s HAMR HDDs will have a capacity of 36TB, using 3.6TB disks. Further down the line, Seagate will build 40TB AMR drives with 4TB disks. In addition, Seagate already has 5TB disks in its labs to build a 50TB drive.
Seagate has launched the IronWolf Pro 22TB model overseas in April this year, which is not yet available in China. The IronWolf Pro 22TB uses a traditional 3.5-inch format and is equipped with a SATA III interface. It uses 10 internal disks and 20 readheads, operates at 7200 rpm, has 512 MB of cache, and offers data transfer speeds of up to 285 MB/s.
