Toshiba said earlier today that it has launched a new desktop, lower cost NAS disk drive, the MN series.

The new units come in a 3.5-inch form factor with 4, 6 and 8 TB capacities. They are air-filled, spinning at 7,200 RPMs, feature a 6 Gbps SATA interface and a 1 million-hour MTBF rating.

We can view them as an update on the MC04, MD04 and MG04 series drives. The MN series are intended for 24/7 operation, and up to 300,000 load/unload cycles.

The average latency rate is 4.17 milliseconds and the drives have rotational vibration sensors to help mitigate its effects. Sequential data transfers operate at up to 230 MiB/s.

So a lower cost doesn't mean that you have to sacrifice quality or performance. Toshiba says the new drives bridge the value gap between top-end enterprise capacity HDDs and entry-level desktop HDDs.

We might compare it to Seagate's BarraCuda desktop drives with their 500 GB to 4 TB capacity range, 7,200 RPMs and 6 Gbps SATA interface, or to Seagate's larger BarraCuda Pro version with its 6, 8 and 10 TB capacity points. Both product types are air-filled.

Looking over at Western Digital's disk drive range for similar products, we shed light on its Purple surveillance drives and Gold data center nearline drives.

Those are air-filled at the 4 and 6 TB capacity points but helium-filled for the 8 and 10 TB levels.

Toshiba introduced its X-300 8 TB desktop drive in May of 2016. The disk maker says these new MN04ACA/MN05ACA series products deliver "the performance and reliability needed for file and object storage workloads that typically utilize sequential data transfer operations."

The target market is basically one needing cost-effective drives for moderate (not data center) workloads with suggested applications being:

-- Mid-level
-- Entry-level
-- SOHO NAS storage enclosures
-- Remote-office backup
-- Archival storage
-- Home multimedia data archive
-- Fixed-content object storage

The drives are available now but we're still waiting for some pricing data from Tochiba. We'll keep you updated.
