Today, there are only three left in the field of mechanical hard disk: Seagate, SISU and Toshiba.

After Western Digital admitted that SMR (laminated magnetic recording) was used for some NAS red disks, Toshiba and Seagate also confirmed that similar phenomena existed in their desktop consumer products.

Toshiba simply lists the main models CMR( traditional magnetic records, basically equivalent to vertical magnetic records) or SMR for consumers to judge

-Model md07aca: 7200 rpm, 12tb, 14tb are CMR (related products are mainly X300 Series)

-Model md04: 7200 rpm, 2, 4, 5, 6GB are CMR (related products are mainly X300 Series)

-Model DT02: 5400 rpm, 4 and 6tb are SMR (related products are mainly P300 Series)

-Model DT01: 7200 rpm, 500GB, 1, 2, 3TB are CMR (related products are mainly P300 Series)

In other words, Toshiba's 3.5-inch P300 desktop hard disk, 4tb (hdwd240uzsva) and 6tb (hdwd260uzsva) use SMR, and users who mind consciously bypass.

Although SMR has effectively improved the hard disk capacity, it has a significant speed drop during long-time or intensive writing. It is also easy to report errors when it is used to configure NAS raid, so it has been criticized and even become a rat in the street. Everyone is shouting.
