18TB SATA enterprise drive

The MaxDigitalData MDD18TSATA25672E is an 18TB 3.5-inch internal hard drive built for nearline workloads. It runs at 7200 RPM with a 256MB cache and a SATA 6.0Gb/s interface. The drive is rated for 24×7 operation in hyperscale and cloud environments.

Sustained 550 TB per year workload

Enterprise-class firmware supports a 550 TB per year workload rate, far above desktop-class limits. A 2.0M hour MTBF and 0.44% AFR reflect the reliability target for continuous duty. Advanced caching technology helps maintain predictable response times under heavy multi-drive chassis loads.

Replaces lower-capacity nearline drives

The 18TB capacity lets operators consolidate storage and reduce the number of drives required for a given footprint. The jump is worth it when scaling bulk-storage SLAs in space-constrained racks. Buyers who need desktop-class intermittent use or portable external storage should look elsewhere.

Questions about this item

How loud and hot does the 7200 RPM MDD18TSATA25672E get during continuous 24×7 operation?

The drive is rated for 24×7 use with an MTBF of 2.0M hours and an AFR of 0.44%, supporting enterprise workloads of 550TB per year.

What cables or brackets must I already have to install this 3.5" SATA 6.0Gb/s drive?

It is a bare drive only — no screws, cables or accessories are included, so you need a SATA data cable, a SATA power connector and 3.5" mounting hardware.

Will this 18TB drive work in my older desktop that only supports smaller capacities?

It uses the standard SATA 6.0Gb/s interface and 3.5" form factor, so any system with a SATA port and 3.5" bay can use it; format the drive in the OS for detection.
