Hard drive Toshiba MG11ACA18TE, 18TB, 7200 RPM, 1024 MB, 3.5", Serial ATA III - 100900623

This hard drive Toshiba MG11ACA18TE from the Toshiba MG11 series is a 3.5" server HDD with a capacity of 18TB, aimed at data center, cloud-scale, and enterprise environments, but fully applicable for more serious NAS and storage solutions as well. It operates at 7200 rpm, with an interface of Serial ATA III (6 Gbit/s), so it easily fits into standard modern systems. It features a massive cache of 1024 MB, which helps with sequential and mixed workloads. The helium-sealed design and CMR with FC-MAMR position it as a serious solution for continuous 24/7 operation.

What you get

With a capacity of 18TB, you can gather huge archives – backups of virtual machines, video surveillance, large media libraries, or long-term logs without frequently worrying about expansion. The Serial ATA III (6 Gbit/s) interface provides sufficient transfer for typical server and NAS scenarios, while the 1024 MB cache memory supports a stable flow during prolonged read/write operations. The drive is rated for 24/7 operation mode and workload of 550 TB/year, making it suitable for environments where data is constantly written and read. The consumption of about 7.41 W during read/write and 3.66 W in active idle is reasonable for a helium-sealed 10-disk design, especially when planning many drives in one cabinet. The high MTBF of 2,500,000 hours, low AFR of 0.35 %, and specified non-recoverable error rate add peace of mind for long-term operation in an enterprise context.

• Capacity 18TB – enough for serious data arrays, backups, archives, and large-scale storage solutions in a server or NAS.
• Server type HDD with a form factor of 3.5" and an interface of Serial ATA III (6 Gbit/s), which integrates easily into standard server and storage platforms.
• 7200 rpm and 1024 MB cache memory for stable and predictable flow during long read and write operations.
• Helium-sealed 10-disk design and Conventional Magnetic Recording (CMR) with FC-MAMR, optimized for reliable operation at high data density.
• 24/7 operating mode and workload of 550 TB/year, directly aimed at data center, cloud-scale, and enterprise applications.
• MTBF 2,500,000 hours, AFR 0.35 %, and non-recoverable error rate 1 in 10^16 read bits, indicating a drive designed for long life and low probability of errors.
• Good durability: up to 50 G shock in operation and up to 200 G non-operating, plus specified vibrations and wide temperature and humidity ranges for harsher environments.

Who it is suitable for

This Toshiba MG11ACA18TE is for you if you are building a serious NAS, backup server, storage for virtualization, or participating in building a data center / cloud-scale infrastructure. It is also suitable for corporate file servers and video surveillance systems, where 24/7 operation and high workload are mandatory. If you need primary gaming storage for a home computer, it may be too “enterprise” in class and capacity, but technically there is no obstacle to using it.

The combination of 18TB, server-class reliability, and 24/7 specifications makes this drive a very strong foundation for long-term storage. It impressively balances capacity, durability, and clearly defined enterprise parameters.
