Toshiba has joined the club of hard drive manufacturers using Microwave Assisted Magnetic Recording (MAMR) technology, as last week introduced the industry's first hard drive with microwave-assisted magnetic recording technology flow controlled (FC-MAMR).
The FC-MAMR is a customization of microwave-assisted magnetic recording technology. The new MG09 series hard drives are primarily designed for near-line and enterprise applications, as well as They offer 18TB capacity and ultra-low standby power consumption.
MG09 series is based on Toshiba's third generation helium-sealed discs, allowing the OEM to increase the Conventional Magnetic Recording (CMR) density to 2TB per disk.
Toshiba has put together 9 dishes on a hard drive this time for a total capacity of 18 TB. The new hard drives are delivered in the standard 3,5-inch format.
According to the company, this format offers a performance of 7200 rpm and easily adapts to cloud storage infrastructure, critical data storage and servers, and file and object storage solutions.
Toshiba said the 18TB CMR capacity is provided through its innovative Flow Control Microwave Assisted Magnetic Recording (FC-MAMR) technology.
"These advancements help the MG09 series achieve optimal storage capacity and application compatibility, with unmatched data reliability," the company said.
Hard drives are manufactured by Showa Denko KK (SDK), a longtime Toshiba partner. Each aluminum tray is about 0,635mm thick, an areal density of approximately 1,5 TB / inch and can store up to 2 TB of data.
MG09 series also includes a 16TB model that probably has fewer trays. The hard drives are equipped with a 512MB buffer memory and are designed for a maximum sustained data transfer rate of 281MB / s.
However, Toshiba hasn't updated random access performance of these newer products, although their IOPS per TB performance is likely to be lower than their predecessors. The manufacturer will offer its new drives with SATA 3.3 (6 Gb / s) and SAS 3.0 (12 Gb / s) interfaces, as well as a selection of logical data block lengths.
One of the main aspects of the FC-MAMR MG09 series hard drives is your energy consumption. According to the company, in active standby mode, consume 4.16 / 4.54 W (SATA / SAS models), which is considerably smaller than the Seagate 'Exos X18' and 'Ultrastar DC HC550' Western Digital models.
When it comes to idle power consumption efficiency (large hard drives can be idle for a long time), the 09TB MG18 achieved record performance as Toshiba said it only consumes 0.23 W / TB (in the case of the SATA version).
Meanwhile, the new units are rated at 8,35 / 8,74 W (SATA / SAS SKU) during read / write operations, which is higher than "DC HC550" as well as the predecessor MG07 and MG08 series.
Because the MG09 hard drive series is designed for data center racks that house hundreds of vibrating hard drives, it features many enhancements to ensure consistent performance, reliability, and durability. Typically these upgrades include top and bottom mounted motors, RVFF (Rotation Vibration Feed Forward) sensors, as well as environmental sensors.
Like all modern units for 24/7 service, Toshiba MG09 series drives are designed for an average annual workload of 550TB, MTBF of 2,5 million hours and are covered by a standard five-year warranty.
In addition, the new MG09 hard drives support Persistent Write Cache technology (PWC) from Toshiba and feature Power Loss Protection (PLP). Protection against power loss is crucial for 4K sector drives that emulate 512B sectors.
The PWC with the PLP function protects data in the event of power loss while performing a read-modify-write (RMW) operation. This aligns the source write request with the physical sectors that you need to modify.
