SMR (laminated magnetic recording) hard disk has recently aroused hot discussion among netizens. Seagate, WD and Toshiba all admit that SMR and CMR (traditional magnetic recording) technologies are used in multiple series of products.

Although SMR hard disk improves the capacity, the biggest defect is the poor write reliability, especially for NAS network storage which needs frequent random read and write, which is also the most controversial place.


Toshiba officials today released a full and up-to-date list of its SMR hard drives, including five series in two areas: a 3.5-inch desktop hard drive and a 2.5-inch laptop hard drive:

In terms of 3.5 inch, P300, DT02 and dt02-v series all use SMR, involving desktop computer, integrated computer, monitoring and other fields, including:

P300- 6TB

- P300 4TB

DT02- 6TB

- DT02 4TB

- DT02-V 6TB

- DT02-V 4TB

In terms of 2.5 inches, the L200 and mq04 series all use SMR, involving notebook, game machine, external hard disk and other fields, including:

L200- 2TB

L200- 1TB

- MQ04 2TB

- MQ04 1TB

Toshiba also stressed that, NAS won't use SMR hard drives like N300 series.



Before that, Seagate also emphasized that Barracuda coolfish and exos Galaxy series hard disks use SMR, but they are clearly marked, and coolwolf NAS hard disks will not use SMR hard disks now or in the future.

In terms of Western Digital, SMR is used for 3.5-inch red disk 2 / 3 / 4 / 6tb, 3.5-inch blue disk 2 / 6tb, 2.5-inch blue disk 1 / 2TB and 2.5-inch black disk 1TB.
