Toshiba crams 14TB into another helium drive, this time with SAS boost

MG07SCA is a workhorse designed for constant use

Toshiba has added a helium-filled 3.5-inch form factor SAS disk drive alongside its equivalent SATA product.

Like the SATA-using MG07ACA, the catchily named MG07SCA comes with 12 and 14TB capacities but uses a dual-port 12Gbit/s SAS interface instead of the 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 MG07SCA, which effectively replaces Toshiba's MG06SCA air-filled drive with its 6Gbit/s SAS interface and 10TB capacity, is intended for constant use. It is said to be 50 per cent more power-efficient than the MG06, and has a 2.5 million-hour mean time to failure rating, 550 total TB transferred per year workload rating and 600,000 load/unload cycles.

There are nine 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 have kept shtum.
