Toshiba MG09ACA 3.5" 18TB, 7200 RPM, 512MB, SATA III Hard Drive, Enterprise

The Toshiba MG09ACA18TA is an enterprise-grade hard disk drive offering an 18 TB storage capacity within a standard 3.5-inch form factor. It connects via a SATA 6.0 Gbit/s interface, ensuring broad compatibility with servers, network-attached storage (NAS), and large-scale storage arrays. The drive operates at a 7200 RPM spindle speed, which contributes directly to its data access and transfer performance. It is engineered for cloud-scale and mission-critical workloads where both high capacity and consistent throughput are primary requirements.

Performance is further supported by a 512 MB cache buffer that optimizes read and write operations for enterprise applications. This model is constructed for long-term reliability in continuous-use environments, evidenced by its 550 TB per year workload rating and a Mean Time Between Failures (MTBF) of 2.5 million hours. It is validated for 24/7 operation and includes S.M.A.R.T. monitoring for predictive drive health diagnostics. For enhanced data protection, Self-Encrypting Drive (SED) options are available to meet specific security protocols.
