The SATA Drive That Powers 70 Percent of Enterprise Backup and Archive Servers

Every backup NAS, every Veeam repository, every Commvault MediaAgent running on a budget needs drives. Not NVMe drives. Not SAS SSDs. SATA hard drives that deliver capacity per dollar, not IOPS per dollar. The Toshiba MG09 18TB is a 7,200 RPM SATA enterprise drive with CMR recording, 2.5 million hours MTBF, and a 550 TB/year workload rating — at a price per terabyte that is roughly 60 percent of the equivalent SAS model. For backup targets, archives, and cold data tiers, the MG09 is the drive that makes the storage budget work.

MG09 SATA vs MG10 SAS — When the Interface Matters and When It Does Not

Recurso	MG09 18TB SATA	MG10 20TB SAS
Interface	SATA 6Gb/s	SAS 12Gb/s (dual-port, full-duplex)
Transfer Rate	281 Mb/s	270 Mb/s
Poder (Idle / Operativo)	2.2C / 4.1C	4.2C / 7.2C
Dual-Port	Não (single-port, single path to RAID controller)	Sim (dual-port, redundant paths — survives HBA failure)
Max Drives per Controller	Typically higher (SATA controllers support more drives)	Lower (SAS expander ports scale differently)
Relative Price	100 percent	~130-140 percent
Best for	Backup targets, archives, cold storage, JBOD, single-controller DAS	Production servers, dual-controller SAN, environments requiring dual-path redundancy
