Toshiba has added a high-capacity helium-filled 3.5-inch form factor SAS disk drive alongside its equivalent SATA product.
Like the SATA-using MG07 ACA, the MG07 SCA has with its 12 and 14TB capacities but uses a dual-port 12 Gbit/s SAS interface instead of the MG07 ACA’s 6Gbit/s SATA link.
The MG07ACA has already spawned an MN07 NAS drive in 10TB and 14TB capacities. Both Western Digital and Seagate have 14TB helium-filled drive products and product categories spread out as the technology matures.
The MG07 SCA, which effectively replaces Toshiba’s MG06 SCA air-filled drive with its 6Gbit/s SASA interface and 10TB capacity, is intended for 24 x 7 use. It is said to be 50 per cent more power-efficient than the MG06, and is rated for a 2.5m hours MTTF, 550 total TB transferred per year workload rating and 600,000 load/unload cycles.
There are 9 platters in the 14TB product; we understand there are 8 in the 12TB model.
It comes with a 256MiB cache and transfers data at 242MiB/s at the 12TB capacity level and 248MiB/s at the 14TB level.
Now that all three drive manufacturers have 14TB products, and Seagate is anticipating shipping a multi-actuator 20TB HAMR-technology product in 2020 we ask ourselves if there will be one more capacity jump with current magnetic recording technology before then? Perhaps to 16TB? The manufacturers are not saying.
