Toshiba Electronic Devices & Storage Corporation ("Toshiba") has announced the addition of new 24 TB models to both its N300 and N300 Pro Series of internal hard disk drives (HDD). The new models offer 2 TB more capacity than current 22 TB versions, making them ideal for increasing the capacity of network attached storage (NAS) and private cloud storage. They are designed for 24/7 operation, feature industry-standard 3.5-inch 7200rpm, 1 GiB buffer, and include integrated sensors to compensate for rotational vibrations.

The N300 Series has a workload rating of up to 180 TB/year with support for up to 12 drive bays, while the N300 Pro Series boasts a workload rating of up to 550 TB/year with support for up to 24 drive bays.

Toshiba today introduced the updated N300 series 3.5-inch internal SATA hard drives targeting NAS applications. These drives come with new product branding the company introduced with its recent S300 series HDDs for surveillance/NVR applications. The drives come in capacities of 2 TB, 4 TB, 6 TB, 8 TB, 10 TB, 12 TB, 14 TB, 16 TB, 18 TB, 20 TB, and 22 TB, with the higher capacity models—12 TB and above—being helium-filled, to reduce power/noise characteristics. All models in the series come with CMR (conventional magnetic recording), which ensures predictable write and rewrite performance. The drives come with 7,200 RPM spindle-speed, and depending on the capacity variant, between 64 MB to 512 MB of write cache. The drives come with SATA 6 Gbps host interface, and offer sequential transfer speeds of up to 281 MB/s reads, with up to 268 MB/s writes, with an MTBF rated between 1-1.2 million hours.
