The introduction of Shingled Magnetic Recording (SMR) technology has enabled HDD manufacturers, such as Toshiba, to increase the capacity of their spinning platter drives beyond that of existing approaches. SMR technology is recognized as having an impact on write-speeds in drives where this technology is used, especially in the case of continuous random writing. For this reason, Toshiba products are carefully tailored to specific workloads and use cases.
For example, in use cases such as network-attached storage (NAS), where continuous random writing regularly occurs, Toshiba’s current product line for consumers features the N300, which does not use SMR.

The P300 / DT02 / DT02-V Desktop PC & Surveillance Hard Drive range of products, which are the product line for client drive application, such as all-in-one PCs, desktop PCs, and surveillance.
In the current range, the following drives do use SMR technology:
  • P300 6TB
  • P300 4TB
  • DT02 6TB
  • DT02 4TB
  • DT02-V 6TB
  • DT02-V 4TB

The L200 / MQ04 Laptop PC Hard Drive range of products,, which are the product line for client drive application, such as notebook PC, game consoles, and external enclosures, etc.
The following drives also use SMR technology:
  • L200 2TB
  • L200 1TB
  • MQ04 2TB
  • MQ04 1TB

Toshiba works extensively with Notebook and Desktop PC vendors on the selection of the appropriate storage media to help ensure the data integrity, reliability and planned lifetime requirements of the system.

seems to be Toshiba is first HDD vendor from rest of two (WD and Seagate) from 2015 who understands that people aren’t stupid and they will discover they step into race for better areal density.
Still is valid the main message: SHR is great for all Storage eaters, based on description in this blog
There is still question, why Toshiba uses for NAS flagship HDD line N300 such wording:

Offering high reliability and scalability, N300 drives achieve a max. 180 TB/year workload factor, up to 3 times more than convenient desktop hard drives.

My note: This workload factor is used by all vendors for SMR disk workload limitation.
