No SMR Anywhere In The Line

Toshiba does one thing in enterprise storage that its two competitors do not

FC-MAMR — flux control microwave-assisted magnetic recording — uses a microwave field to make the platter momentarily easier to write, which allows higher density without moving to shingled recording. Every MG drive from MG09 upward is conventional recording. There is no SMR anywhere in the MG line, and no capacity tier where you have to trade rewrite performance for density.

That is a real simplification. On the Seagate and WD enterprise ranges, the highest capacities are shingled and unsuitable for random rewrite. On MG, a 24 TB drive behaves like a 4 TB drive, only larger.

Elite Infotech supplies the MG range across Oman for servers, storage arrays, RAID and archive tiers.

Enterprise hard drive platters and actuator, the mechanism behind Toshiba FC-MAMR conventional recording in the MG series — FC-MAMR raises areal density without shingling adjacent tracks

Practical Reference

Reading a Toshiba MG model number

The part number tells you the interface and the sector format before you look anything up. This is more useful than it sounds when you are checking a delivery against a purchase order.

MG11ACA24TE is an MG11 platform, SATA interface, 24 TB, 512e sector format.
MG10SDA400N is an MG10-D platform, SAS interface, 4 TB, native 512n.

When 512n actually matters

The 512n models exist for legacy systems and hypervisors that require native 512-byte sectors. If your platform does not specifically need it, the E and TE variants are faster — 268 MB/s against 211 to 228 MB/s on the MG10-D range.

Specify MG11 on new builds

All four carry MTTF of 2,500,000 hours at 0.35% AFR, 550 TB/year, 7,200 RPM and a five-year warranty. MG11 is the current generation — double the buffer and roughly 10% higher sustained transfer than MG10 at the same capacity.

MG09 model numbers

SAS 4Kn: MG09SCA12TA, MG09SCA14TA, MG09SCA16TA, MG09SCA18TA. SAS 512e: MG09SCA12TE, MG09SCA14TE, MG09SCA16TE, MG09SCA18TE. SATA follows the same pattern with ACA in place of SCA. The 512e models include Persistent Write Cache Technology for power-loss protection.

MG10 and MG10-F model numbers

MG10 SAS: MG10SCA20TA (4Kn), MG10SCA20TE (512e). MG10 SATA: MG10ACA20TA, MG10ACA20TE. MG10-F SATA: MG10AFA20TE, MG10AFA22TE. MG10-F SAS: MG10SFA20TE, MG10SFA22TE.

MG11 model numbers

SATA: MG11ACA14TE, MG11ACA16TE, MG11ACA18TE, MG11ACA20TE, MG11ACA22TE, MG11ACA24TE. SAS: MG11SCA14TE through MG11SCA24TE. Default format is 512e, convertible to 4Kn on most models.

Raise cooling before you quote

The 55°C operating ceiling is tighter than the surveillance range and tighter than some competitor enterprise drives. On any Oman deployment in an uncooled or marginally cooled equipment room, raise this with the client before quoting.

Deployment

Where MG series is specified in Oman

Servers, virtualisation hosts and RAID arrays — CMR throughout means no capacity tier is off-limits
Software-defined and object storage deployments
Backup and archive targets, disk-to-disk
Government and banking storage requiring SIE or SED drives
Legacy systems and hypervisors requiring native 512n sectors — the MG10-D N models
Centralised long-term surveillance archive behind multi-site recorders

For the recorders themselves, S300 or S300 AI remain correct. MG belongs at the server and archive tier.

FAQ

Frequently asked questions

Do any Toshiba MG drives use SMR?

No. The entire MG line is conventional recording, using FC-MAMR to reach high capacity rather than shingling. This is a genuine difference from the competing enterprise ranges, where the highest capacities are shingled and unsuitable for random rewrite workloads.

What is FC-MAMR?

Flux control microwave-assisted magnetic recording. A microwave field makes the platter momentarily easier to write, allowing higher areal density without shingling. MG11 uses a second-generation implementation reaching roughly 2.4 TB per disk.

Should I choose SATA or SAS?

SATA for single-controller servers and cost-sensitive capacity tiers. SAS for enterprise arrays needing dual-path redundancy and deeper command queuing. Both are available across most MG capacities at the same platform specification.

What is the difference between 512n, 512e and 4Kn?

512n is native 512-byte sectors, needed by some legacy systems and hypervisors. 512e presents 512-byte sectors while using 4096-byte physical sectors. 4Kn is native 4096-byte. Unless your platform specifically requires 512n, the 512e and 4Kn variants are faster.

What is the difference between MG10 and MG11?

MG11 doubles the buffer to 1 GiB, reaches 24 TB against 20 TB, and delivers up to 295 MiB/s against 268 MiB/s using second-generation FC-MAMR. On new builds, specify MG11.

What warranty applies?

Five years across the MG family, through authorised distribution with regional support.
