Toshiba N300 12TB review

The N300 12TB is a NAS hard drive with 12TB of capacity and a 7,200 rpm spindle. Toshiba rates it for NAS enclosures of up to 12 bays. That puts it in reach of home and small-office boxes as well as larger rackmount units. The 12TB model belongs to Toshiba's helium-sealed N300 line.

The main appeal is a conventional, RAID-friendly specification at a price owners describe as attractive. The main trade-offs are the three-year warranty and the noise that comes with a 7,200 rpm drive.

This drive uses CMR. For anyone building or expanding a NAS pool, that is a point in its favour. It sits alongside the 12-bay rating and the 180TB per year workload figure covered below, and together they make up a conventional NAS specification.

Toshiba lists a workload rating of up to 180TB per year and a reliability figure of 1.2 million hours MTTF. The bay rating is up to 12. These are solid numbers for a multi-drive NAS. The workload figure is a ceiling rather than a target. Heavy write loads, such as constant video ingest or large database churn, could push towards it.

The 12-bay rating gives headroom if you plan to add drives later, since Toshiba rates the drive for enclosures of up to 12 bays rather than only a small box.

Toshiba's press release for the 12TB and 14TB models gives a sustained transfer rate of up to 253MB/s for the 12TB drive. The manufacturer's main N300 page quotes up to 298MB/s across the range. For this capacity, the 253MB/s figure is the one that applies.

Owner feedback supports the rated numbers. One theme is that real-world speed comes close to what Toshiba claims, and owners pair that praise with the attractive price.

The manufacturer's main page says up to 1GB across the range, a third-party page gives 256MB and Micro Center gives 512MB for the 12TB. If cache size matters to you, check the exact listing before you buy.

The drive spins at 7,200 rpm. Owner reports on noise are mixed but lean positive. One theme praises quiet and cool running. One owner calls it a bit noisy but reliable. Your enclosure, drive count and where the NAS sits will all affect how much you hear.

If the NAS lives in a cupboard, garage or rack, this matters less. If it sits in a bedroom or a quiet office, the one noise complaint is worth weighing. Toshiba's listed specifications give no separate power figures to compare here, so the owner comments on cool running are the best guide.

The N300 carries a limited warranty of three years. Owners list that as a complaint. Three years is workable for a drive in a redundant array, but it is shorter than some buyers want for 12TB of storage they expect to keep for years. No data recovery service is listed with it, so backups remain your own responsibility.

The drive suits homelabbers and small offices who are filling NAS bays and want CMR, a 180TB/year workload rating and sustained speeds rated at up to 253MB/s. It also suits people who want headroom for a larger enclosure, given the 12-bay rating.

It suits buyers less well if warranty length decides the purchase, or if the NAS sits within earshot of where you work or sleep. In those cases, the three-year cover and 7,200 rpm spindle are the points to weigh against the price owners like.
