MG07SCA12TEY Toshiba 12TB SAS: MG07 vs MG08 and Fit Guide
The MG07SCA12TEY is a Toshiba MG07 12TB SAS drive, from the generation before the MG08, and it is still widely sought because arrays built on it are still in service. This covers what it is, how the suffix decodes, and what to check.
What is the Toshiba MG07SCA12TEY?
A 3.5 inch, 12TB, SAS 12Gb/s enterprise nearline hard drive from the Toshiba MG07 family. 7200 RPM class, helium filled, conventional magnetic recording, 512e sector format, rated for continuous operation.
Toshiba encodes the specification: SCA is SAS, ACA is SATA, and the final letters identify sector format and feature variant. So MG07SCA12TEY is SAS 512e; MG07ACA12TE is the SATA sibling. Our part numbers guide covers reading vendor codes.
MG07 vs MG08: what changed?
Generation and top capacity. The MG08 extended the range to 16TB with refinements to the platter stack; the MG07 topped out at 14TB. At 12TB both exist, and the MG07 is usually cheaper as older stock.
For matching an existing MG07 array, buy MG07. For a new build, MG08 is newer stock with the same reliability class. Our MG08 16TB guide covers the successor.
Is the MG07SCA12TEY CMR?
Yes. Helium filled, conventional recording, suitable for RAID and array use. Our SMR vs CMR guide and helium guide cover what each means.
Why SAS at 12TB?
Dual-port for multipath, SAS backplanes, or matching an existing SAS array. For a single-controller server or NAS, the SATA sibling costs less. Our dual-port guide covers when the second port is actually used.
What to check before buying
SAS controller with capacity support for 12TB. Sector format matching the array. Firmware coding behind Smart Array or PERC, where vendor-coded is safer. Carrier for hot-swap. And on a used unit, hours and health data, since MG07 stock is now several years old. Our hours guide covers judging them.
Frequently asked questions
Is the MG07SCA12TEY SAS or SATA?

Should I buy MG07 or MG08 at 12TB?
MG07 to match an existing MG07 array. MG08 for a new build, as newer stock in the same class.

What RAID level for 12TB drives?
RAID 6 or equivalent with a hot spare. Rebuilds at 12TB take many hours.
What should I check on a used MG07SCA12TEY?
Hours, reallocated sectors and helium level. MG07 stock is several years old.
