Use of Shingled Magnetic Recording (SMR) technology in Toshiba Consumer Hard Drives

April 29, 2020

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.

In the current range, the following drives do use SMR technology:

The P300 Desktop PC Hard Drive range of products, which is the product line for client drive applications such as all-in-one PCs and desktop PCs.

  • P300 6TB – HDWD260UZSVA (Bulk)
  • P300 4TB – HDWD240UZSVA (Bulk)

The L200 Laptop PC Hard Drive range of products, which is the product line for client drive applications such as notebook PC, game consoles, and external enclosures, etc.

·         L200 2TB – HDWL120UZSVA (Bulk), HDWL120EZSTA (Retail), HDWL120XZSTA (Retail)

·         L200 1TB – HDWL110UZSVA (Bulk), HDWL110EZSTA (Retail), HDWL110XZSTA (Retail)

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.
