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

Особенность	MG09 18TB SATA	MG10 20TB SAS
Интерфейс	SATA 6Gb/s	SAS 12 Гбит/с (dual-port, full-duplex)
