The N300 Pro is the higher-rated half of Toshiba's NAS range. Toshiba's line-up table gives it a workload of up to 550TB a year, support for up to 24 drive bays, a five-year limited warranty and capacities up to 24TB. The standard N300 is rated for up to 180TB a year, up to 12 bays and three years, from 4TB to 22TB. Both are 7200 RPM and CMR at every capacity. Few N300 Pro models are usually in stock, so the standard N300 table sits beside it.

Where the figures come from
Toshiba's N300 product page and the line-up table on it, read on October 12, 2026. Toshiba gives an MTTF of up to 1.2 million hours for the standard N300 and notes that it depends on the model; the page gives no MTTF for the Pro.

When the Pro is the right one
Three cases. Your NAS has more than twelve bays, which is past what Toshiba supports the standard N300 for. You want 24TB, which the standard range does not reach. Or you want five years of cover on a drive you will run for a long time.
For a home NAS of twelve bays or fewer at 22TB or below, the standard N300 is rated for the job, and it is normally the cheaper of the two per terabyte. Unlike WD's two NAS ranges, both Toshiba ranges spin at 7200 RPM, so there is no quieter, slower option to choose between them.
